What are the most common roofing problems in Hobart?

The most common roofing problems in Hobart include cracked or missing tiles from storm damage and falling branches, deteriorating ridge and hip caps from mortar breakdown, valley corrosion particularly in coastal suburbs like Bellerive and Howrah, moss and lichen growth in sheltered areas like Lenah Valley and South Hobart, metal roof corrosion from salt air exposure on the Eastern Shore, flashing failures around chimneys and penetrations, blocked gutters causing water backup, and structural sagging from long-term water damage. Tasmania's challenging climate with powerful westerlies, heavy rainfall, salt air in coastal areas, and extended damp periods creates unique stress on roofing systems that requires regular monitoring and maintenance.

How can I check my roof for problems without climbing on it?

You can safely check your roof from ground level using binoculars to examine roof surfaces for visible damage, missing or cracked tiles, ridge cap condition, moss or lichen growth, and gutter condition. Walk completely around your property to view all roof sections. Inside your home, check ceilings for water stains, paint bubbling, or dampness. If you can safely access your roof cavity, look for water stains on rafters, daylight through the roof, mold growth, or damaged insulation. Take dated photos of anything concerning. Watch for roofing material on the ground after storms. Never walk on your roof yourself—according to Safe Work Australia, falls from roofs cause serious injuries. Ground-level inspection combined with professional roof inspections every 2-3 years provides comprehensive monitoring.

When should I call a professional about roof problems?

Call professionals immediately if you see active leaks with water entering your home, structural sagging or irregular roof lines, multiple damaged tiles or large roof sections damaged, ridge caps failing or displaced, or any safety hazards. Call within a week for new cracks in several tiles, changes in ridge or hip condition, new rust or corrosion areas, flashing gaps or damage, or gutter problems causing water issues. Schedule inspection within a month for gradual moss or lichen increases, minor surface rust on metal, aging but not yet failing components, or any uncertainty about what you're seeing. Don't delay on active problems—small issues caught early cost $300-$800 to repair, while delayed problems can cost $3,000-$8,000 with interior damage.

Is moss on my roof a serious problem?

Yes, moss is more than cosmetic and creates real problems for Hobart roofs. Moss retains moisture against roofing surfaces keeping them damp far longer than they should be, which accelerates tile degradation. Heavy moss growth can physically lift tile edges creating gaps for water entry. Moss roots work into tile surfaces gradually breaking down protective glazing and the material itself. Moss makes roofs dangerously slippery for any necessary access. In sheltered Hobart suburbs like Lenah Valley and South Hobart, moss growth is particularly aggressive due to shade and moisture. Professional roof cleaning every 2-3 years ($1,200-$2,800) removes moss and applies treatments that slow regrowth. Never pressure wash your roof yourself—excessive pressure damages tiles and improper technique forces water under tiles creating leaks.

How do I know if my metal roof is corroding?

Early warning signs of metal roof corrosion include small rust spots often starting at fastener locations, paint fading or chalking beyond normal aging, bubbling or blistering paint, color changes indicating corrosion under paint, and white or red staining from rust leaching out. Advanced problems show visible rust spreading across panels, paint peeling in large sections, perforation (actual holes rusted through), buckled or warped panels, and fasteners that have rusted through. In coastal Hobart suburbs like Bellerive, Howrah, Sandy Bay, and the Eastern Shore, corrosion develops much faster due to salt air. Standard-grade Colorbond in coastal locations often shows problems within 15-20 years rather than the 40-50 year lifespan expected inland. Annual freshwater washing removes salt buildup and extends roof life. Touch up any scratches immediately with matching paint to prevent rust starting.

What does deteriorating ridge capping look like?

From ground level with binoculars, deteriorating ridge caps show visible gaps between ridge or hip tiles, crumbling or missing mortar, ridge tiles that appear uneven or tilted, white powder or residue from deteriorating mortar, ridge tiles that have shifted position, and cracks in visible mortar bedding. Inside the roof cavity, you might see daylight along the ridge line or water stains on timber near the ridge. Ridge deterioration is extremely common in Hobart because ridge caps sit at the highest, most exposed part of your roof taking the full force of sun, wind, rain from all directions, and temperature extremes. The mortar bedding typically needs attention every 15-25 years even when tiles are excellent. Coastal exposure accelerates this—salt air breaks down mortar faster. Catching deterioration early costs $600-$1,500 for repointing specific sections, while complete ridge failure requiring emergency repairs costs $2,500-$5,000 plus any interior water damage.

Are cracked tiles always a serious problem?

Even a few cracked tiles are concerning because every damaged tile is a potential water entry point. A single cracked tile can allow moisture into your roof cavity during heavy rain, where it saturates insulation, rots timber framing, and eventually creates ceiling leaks. However, the urgency depends on the extent: 1-3 damaged tiles from a specific cause (fallen branch, foot traffic) is straightforward repair territory costing $200-$500 and should be addressed within weeks. Widespread tile damage (10+ tiles across different areas) suggests either a recent event affecting the whole roof (hail storm) or general roof deterioration requiring comprehensive assessment—this needs professional evaluation immediately. Hairline cracks that haven't broken through yet can be monitored short-term but should be replaced proactively as freeze-thaw cycles in Hobart winters will turn hairline cracks into full breaks within 1-2 years.

How quickly do roof problems get worse in Hobart's climate?

Roof problems accelerate quickly in Tasmania's challenging climate. A small crack in one tile can become a major leak within one winter season of heavy rainfall and freeze-thaw cycles. Minor rust spots on coastal metal roofs can spread significantly within 6-12 months due to constant salt air exposure. Valley corrosion that seems minor can perforate within 1-2 years once protective coatings are compromised. Moss growth doubles in coverage within one damp winter season if untreated. Deteriorating ridge mortar progresses from minor cracks to complete failure within 2-3 years once breakdown begins. The key accelerator is Tasmania's extended wet periods—roofing materials don't dry out properly, so damage compounds rather than stabilizing. This is why early detection and prompt roof repair in Hobart is so critical—the window between 'minor problem' and 'expensive emergency' is shorter here than in drier, more stable climates.

How to Spot Roofing Problems that are common in Hobart

Most roof problems—they develop gradually, quietly, and often invisibly until something makes them obvious. By then, what could have been a $300 repair can become a $3,000 emergency.

After twenty years working on Hobart roofs, we’ve developed a trained eye for spotting problems. But you don’t need two decades of experience to identify the warning signs that your roof needs attention. You just need to know what to look for and where to look for it.

This guide will walk you through the most common roofing problems in Hobart and surrounding areas, teach you how to spot them early, and explain what each problem means for your roof’s health. Some issues you can safely identify yourself from ground level; others require professional inspection. Either way, early detection is your best defense against expensive roof repair or premature roof replacement in Hobart.

Why Hobart Roofs Develop Specific Problems

Before we dive into spotting problems, it helps to understand why certain issues are so common in our region.

Our Weather Creates Unique Stresses

Tasmania’s climate isn’t just one thing—it’s many things happening in succession. We get powerful westerlies that stress roofing fasteners and can lift materials, heavy rainfall that tests every seal and flashing point, salt air in coastal areas accelerating corrosion, temperature swings causing expansion and contraction, occasional hail damaging surfaces, and extended damp periods promoting biological growth.

Each of these environmental factors creates specific types of damage. Understanding the cause-and-effect relationship helps you know where to look for problems.

Coastal vs. Inland: Different Challenges

A roof in Bellerive faces different challenges than one in Brighton. Coastal properties battle constant salt exposure that corrodes metal components far faster than inland locations. Sheltered valleys in suburbs like Lenah Valley or South Hobart develop moss and lichen problems that exposed coastal roofs rarely see.

Your roof’s specific problems depend partly on your micro-climate. For comprehensive guidance on maintaining roofs in Tasmania’s varied conditions, see our article on Why Regular Roof Inspections Are Essential for Tasmanian Homes.

Age Matters More in Harsh Conditions

A roof might last 50 years in stable, dry conditions. In Hobart’s environment, that same roof under constant environmental stress might show problems at 30-35 years. This isn’t a failure of materials—it’s simple reality of challenging conditions.

Knowing your roof’s age helps you understand whether problems indicate premature failure or expected end-of-life issues. If you’re unsure whether problems warrant repair or full replacement, our guide on How to Tell if Your Roof Needs Repairs or a Full Replacement provides detailed decision-making criteria.

Common Problem #1: Cracked, Broken, or Missing Tiles

This is perhaps the most visible problem and one of the easiest to spot from ground level.

What to Look For

Obvious signs:

◉ Tiles on the ground, in gutters, or in your yard
◉ Visible gaps in roof coverage where tiles should be
◉ Tiles that appear to be sitting at wrong angles
◉ Cracked tiles visible even from street level

Subtle signs requiring binoculars:

◉ Hairline cracks that catch the light differently
◉ Chips or breaks at tile edges
◉ Tiles that have slipped slightly out of position
◉ Color mismatches where replacement tiles don't quite match

Where This Problem Occurs Most

High-risk areas:

◉ Roof valleys (highest water flow, most stress)
◉ Ridges and hips (most exposed to wind)
◉ Lower roof sections near trees (branch impact)
◉ Areas with foot traffic (around chimneys, near access points)
◉ South-facing slopes (less sun, more moisture, more freeze-thaw cycles)

What Causes Tile Damage in Hobart

Common causes:

◉ Falling branches (extremely common in treed suburbs like Mount Stuart, Lenah Valley, or South Hobart)
◉ Foot traffic during maintenance or service installations
◉ Hail impact (we get occasional hail events that damage tiles across entire neighborhoods)
◉ Age-related brittleness (tiles become more fragile after 40-50 years)
◉ Freeze-thaw cycles (water enters small cracks, freezes, expands, breaks tile)
◉ Manufacturing defects that only become apparent with age

Why This Matters

Every damaged or missing tile is a potential water entry point. Even a single cracked tile can allow moisture into your roof cavity during heavy rain. Once water enters, it can:

Saturate insulation (reducing thermal performance and potentially causing mold)
Rot timber framing (structural damage that’s expensive to repair)
Create ceiling leaks (interior damage to plaster, paint, and furnishings)
Spread to adjacent areas (one small leak becomes multiple problems)

What to Do

If you spot 1-3 damaged tiles: This is straightforward roof repair territory. Call a professional for individual tile replacement. Cost typically depends on tile type and access.

If you see widespread tile damage (10+ tiles): This suggests either a specific cause (recent hail storm affecting the whole roof) or general roof deterioration. Get comprehensive professional assessment to determine whether targeted repairs or broader roof restoration makes more sense.

Don’t wait: Tile damage doesn’t improve with time. Address it promptly before water damage occurs.

Common Problem #2: Deteriorating Ridge and Hip Caps

Ridge and hip problems are incredibly common in Hobart, yet many homeowners never look closely enough to notice them developing.

What to Look For

From ground level with binoculars:

◉ Visible gaps between ridge/hip tiles
◉ Crumbling or missing mortar
◉ Ridge tiles that appear uneven or tilted
◉ White powder or residue (deteriorating mortar)
◉ Ridge tiles that have shifted position
◉ Cracks in visible mortar bedding

Inside the roof cavity (if you can safely access it):

◉ Daylight visible along the ridge line
◉ Water stains on timber near the ridge
◉ Deteriorated mortar fallen into roof space

Why This Problem Is So Common

Ridge and hip caps sit at the highest, most exposed part of your roof. They take the full force of sun, wind, rain from all directions, and temperature extremes. The mortar bedding that holds them in place deteriorates faster than almost any other roof component.

In Hobart’s climate, ridge mortar typically needs attention every 15-25 years, even when the tiles themselves are in excellent condition. Coastal exposure accelerates this—salt air breaks down mortar more quickly.

Warning Signs of Imminent Failure

Critical signs requiring immediate attention:

◉ Ridge tiles that move when touched (if you can safely access the roof)
◉ Multiple sections of completely missing mortar
◉ Ridge tiles that have fallen off (even if they're caught in gutters)
◉ Large gaps visible from ground level

Geographic Variation in Hobart

Ridge deterioration happens faster in:

Coastal suburbs (salt accelerates mortar breakdown)
Wind-exposed locations (Mount Nelson, elevated Eastern Shore properties)
North and west-facing ridges (maximum sun and weather exposure)

Slower deterioration occurs in:

Sheltered locations
South-facing ridges (less sun and weather exposure)
Newer roofs with modern mortar formulations

Common Problem #3: Valley Problems and Corrosion

Valleys are critical roof components that channel large volumes of water. When they fail, you get significant leaks.

What to Look For

Valleys are harder to see from ground level, but you can spot warning signs:

Visual clues from the ground:

◉ Rust staining running down from valley areas
◉ Paint peeling or bubbling near valleys
◉ Water overflow marks on walls near valleys
◉ Discoloration or staining on valley metal visible from certain angles

Inside the roof cavity:

◉ Water stains on rafters near valleys
◉ Rust perforation in valley irons (holes or thin spots)
◉ Daylight visible through valley sections
◉ Active rust or corrosion

During rain:

◉ Water overflowing valley edges rather than channeling properly
◉ Leaks appearing near valley areas

Why Valleys Fail in Hobart

Valley irons are typically made from zincalume or similar metal products. In inland Hobart locations with minimal salt exposure, they might last 30-35 years. In coastal suburbs, they often fail in 15-20 years.

Failure causes:

◉ Coastal salt corrosion (Eastern Shore, Sandy Bay, coastal Kingston)
◉ Standing water from inadequate pitch or debris blockage
◉ Galvanic corrosion where dissimilar metals contact each other
◉ Thermal stress from expansion/contraction cycles
◉ Aging protective coatings allowing rust to begin

High-Risk Locations for Valley Problems

If your home is in Bellerive, Howrah, Lauderdale, Seven Mile Beach, or any Eastern Shore location, inspect valleys more frequently. Salt air dramatically accelerates valley iron corrosion.

Similarly, if your valleys have minimal pitch (flatter angles), they’re more prone to standing water and earlier failure.

Common Problem #4: Moss, Lichen, and Biological Growth

This is perhaps the most visible problem in Hobart’s sheltered suburbs, yet many homeowners don’t realize it’s actually a problem.

What to Look For

Moss and lichen are obvious once they develop:

◉ Green, black, or orange growth on roof surfaces
◉ Thick coverage in shaded areas
◉ Growth concentrated on south-facing slopes
◉ Moss extending from roof edges upward
◉ Heavier growth under overhanging tree branches

Where This Problem Develops

Where This Problem Develops Highest risk areas:

◉ Lenah Valley (sheltered, tree-covered, limited sun)
◉ South Hobart valleys (similar conditions)
◉ Mount Stuart (heavy tree coverage in many areas)
◉ Any property with overhanging trees creating shade
◉ South-facing roof slopes (limited direct sun)

Lower risk areas:

◉ Coastal properties (salt air and wind inhibit growth)
◉ North and west-facing slopes (more sun exposure)
◉ Properties without nearby trees
◉ Exposed, wind-swept locations

Why Biological Growth Matters

Many homeowners think moss is just cosmetic, but it creates real problems:

Moisture retention: Moss holds water against roofing surfaces, keeping them damp far longer than they should be. This accelerates tile degradation and promotes rot in any timber components.

Physical lifting: Heavy moss growth can physically lift tile edges, creating gaps for water entry.

Surface damage: Moss roots (yes, moss has roots) work into tile surfaces, gradually breaking down protective glazing and the tile material itself.

Weight: Extensive moss coverage adds weight to your roof—not usually structurally significant, but it does add load.

Slipping hazard: Moss makes roofs dangerously slippery, increasing risk during any necessary roof access.

The Cleaning Question

Homeowners often ask: “Should I clean the moss myself?”

The answer is no. Here’s why:

Pressure washing roofs is genuinely hazardous:

◉ Walking on moss-covered tiles is extremely slippery and dangerous
◉ Excessive pressure damages tiles and blasts away surface glazing
◉ Water forced upward under tiles creates leaks
◉ You risk serious injury from falls

Professional roof cleaning involves:

◉ Proper safety equipment and training
◉ Appropriate pressure levels for your specific tile type
◉ Correct water direction (always downward, never up under tiles)
◉ Chemical treatments that kill biological growth and slow regrowth
◉ Gutter clearing to remove all debris
◉ Full insurance coverage for any accidents

According to Safe Work Australia, falls from roofs are a leading cause of serious injury and death. Leave roof work to professionals.

Moss Management Strategy

For properties prone to moss growth:

Every 2-3 years: Professional cleaning and treatment (cost will depend on roof size)

Between cleanings:

Trim overhanging branches to increase sun exposure
Clear gutters regularly so water doesn’t back up under tiles
Monitor growth and schedule cleaning before it becomes heavy

Long-term: Consider preventative treatments that inhibit growth for 2-4 years after cleaning

For comprehensive seasonal maintenance guidance including moss management, see our article on Spring Roof Care Tips Every Tasmanian Homeowner Should Know.

Common Problem #5: Metal Roof Corrosion and Paint Degradation

Colorbond and metal roofing are popular in Hobart, but they face specific problems in our environment.

What to Look For on Metal Roofs

Early warning signs:

◉ Small rust spots (often starting at fastener locations)
◉ Paint fading or chalking (more than expected aging)
◉ Bubbling or blistering paint
◉ Color changes indicating corrosion under paint
◉ White or red staining (rust leaching out)

Advanced problems:

◉ Visible rust spreading across panels
◉ Paint peeling in large sections
◉ Perforation (actual holes rusted through metal)
◉ Panels that have buckled or warped
◉ Fasteners that have rusted through

Areas to check specifically:

◉ Valleys and low points (water collects)
◉ Fastener locations (penetrations through protective coating)
◉ Roof edges and capping
◉ Any areas of standing water or poor drainage
◉ Flashing around chimneys and penetrations

Coastal vs. Inland Corrosion Patterns

In coastal Hobart suburbs (Bellerive, Howrah, Sandy Bay, Eastern Shore):

Corrosion develops much faster. Salt particles in the air gradually penetrate protective coatings. Even “coastal-rated” Colorbond experiences more stress here than inland.

Standard-grade Colorbond installed in coastal locations often shows problems within 15-20 years rather than the 40-50 year lifespan expected inland.

In inland Hobart areas (Kingston, Brighton, Glenorchy):

Corrosion develops more slowly. Properly installed Colorbond with appropriate maintenance typically reaches expected lifespan without significant problems.

What Causes Premature Metal Roof Corrosion

Common causes in Hobart:

◉ Wrong product specification (standard grade in coastal location)
◉ Inadequate maintenance (salt buildup not washed off)
◉ Scratches or damage to protective coating
◉ Dissimilar metals in contact (galvanic corrosion)
◉ Standing water from poor drainage
◉ Chemical exposure (some tree species produce acidic runoff)

Prevention and Early Intervention

For coastal properties:

◉ Annual freshwater washing removes salt buildup
◉ Immediate attention to any scratches or damage
◉ Use coastal-rated materials from the start
◉ More frequent inspections (annually vs. every 2-3 years)

For all metal roofs:

◉ Touch up any scratches promptly with matching paint
◉ Keep roof and gutters clear of debris
◉ Address standing water problems immediately
◉ Professional inspection every 2-3 years minimum

When corrosion appears:

◉ Small rust spots: Professional assessment and treatment
◉ Multiple corroded areas: May indicate systemic problem requiring professional evaluation
◉ Perforation: Usually means panel replacement
◉ Widespread corrosion: Consider metal roof replacement or roof restoration

Common Problem #6: Flashing Failures Around Chimneys and Penetrations

Flashing creates waterproof seals where your roof meets chimneys, vents, skylights, or walls. When flashing fails, you get leaks—often in confusing locations.

What to Look For

External signs:

◉ Gaps between flashing and the surface it seals against
◉ Cracked or deteriorated sealant
◉ Rust or corrosion on metal flashing
◉ Loose or lifting flashing edges
◉ Damaged or missing flashing components

Internal signs:

◉ Water stains on ceilings near chimneys or walls
◉ Damp spots appearing during rain near penetrations
◉ Rust stains on ceiling near metal penetrations
◉ Mold growth near flashing locations

Why Flashing Fails in Tasmania

Thermal stress: Flashing materials expand and contract with temperature changes. After years of cycling between cold winters and hot summers, sealants crack and metal fatigues.

UV degradation: Sealants exposed to sun break down, becoming brittle and cracking.

Wind-driven rain: Hobart’s wind patterns can drive rain horizontally, testing flashing seals from angles that normal rainfall wouldn’t.

Corrosion: Metal flashing, particularly in coastal areas, corrodes over time.

Poor initial installation: Some flashing problems trace back to incorrect installation techniques that only reveal themselves years later.

Most Common Flashing Problem Locations

Chimney flashing (especially on older chimneys with complex brickwork)
Skylight installations (both the skylight seal and roof penetration seal)
Vent pipes (plumbing vents, exhaust vents)
Wall junctions (where roof meets vertical walls)
Antenna or satellite dish mounts (penetrations through roofing)

Common Problem #7: Gutter Problems Affecting Roof Health

While gutters aren’t technically part of your roof, gutter problems cause roof damage.

What to Look For

Obvious problems:

◉ Gutters sagging or pulling away from fascia
◉ Visible rust or holes in gutters
◉ Water overflowing during rain
◉ Plants growing in gutters (indicates long-term debris buildup)
◉ Downpipes disconnected or damaged

Subtle signs:

◉ Water staining on fascia boards or walls below gutters
◉ Paint peeling on eaves or walls near gutters
◉ Puddles forming against house foundation after rain
◉ Rust stains streaking down from gutter joints

How Gutter Problems Damage Roofs

Water backup: When gutters are blocked or inadequate, water backs up under roof edges. This can saturate fascia boards, penetrate under roofing materials, and enter wall cavities.

Fascia rot: Overflowing gutters constantly wet fascia boards, causing rot. Fascias support gutter systems and roof edges—when they rot, both gutters and roof edges can fail.

Ice damming: In cold Hobart winters, backed-up water can freeze, creating ice dams that force water up under roofing materials.

Weight stress: Gutters full of water and debris become extremely heavy, stressing mounting brackets and pulling away from fascia.

Maintenance Requirements

Minimum gutter maintenance:

◉ Spring cleaning (after autumn leaves)
◉ Autumn cleaning (before winter rains)
◉ Additional cleaning if you have nearby trees

For properties with heavy tree coverage:

◉ Quarterly gutter checks
◉ Consider gutter guards (though these need maintenance too)
◉ More frequent downpipe checks (blockages cause backup)

Common Problem #8: Structural Issues (Sagging, Uneven Roof Lines)

This is the warning sign that should never be ignored.

What to Look For

From outside:

◉ Roof lines that appear wavy rather than straight
◉ Noticeable dips in ridgelines
◉ Uneven eaves (one section lower than others)
◉ Visible sagging between support points

From inside roof cavity:

◉ Rafters that appear bowed or bent
◉ Cracked or split structural timber
◉ Timber that feels soft or spongy (rot)
◉ Structural members that have moved or shifted

What Causes Structural Problems

Water damage and rot: Long-term leaks saturate roof framing. In Tasmania’s damp climate, this timber doesn’t dry properly, leading to rot and loss of structural strength.

Inadequate original design: Some older homes have undersized rafters or insufficient bracing for modern loading (especially if tiles were added to roofs originally built for lighter materials).

Termite damage: In some Hobart areas, termites attack roof framing, compromising structural integrity.

Overloading: Excessive roofing material weight beyond what the structure was designed to support.

Age and fatigue: Timber naturally weakens over decades, particularly in Tasmania’s moisture-variable climate.

Why This Is Dangerous

Structural problems indicate serious safety concerns:

Risk of collapse, particularly under snow load or during severe storms
Accelerated deterioration once structural integrity is compromised
Potential damage to walls and foundations as stress transfers
Major safety hazard for anyone accessing the roof

What to Do

If you notice any structural irregularities:

Do not delay. Call licensed roofing professionals immediately for assessment. Some structural problems require temporary bracing while planning permanent repairs.

Structural repairs typically involve:

Comprehensive structural engineering assessment
Timber replacement and reinforcement
Often coupled with full roof replacement
Building permit requirements

For guidance on whether structural problems require complete replacement, see our guide on How to Tell if Your Roof Needs Repairs or a Full Replacement.

How to Conduct Your Own Visual Inspection

You can spot many problems with careful observation from ground level—no need to access the roof yourself.

Monthly Quick Check (5 minutes)

Walk around your property looking at:

◉ Overall roof appearance (anything obviously different?)
◉ Gutters (any overflow stains or sagging?)
◉ Ground around house (any roof material or debris?)
◉ Visible damage or changes from ground level

This quick monthly check catches obvious changes like storm damage or sudden material failure.

Quarterly Detailed Check (20-30 minutes)

With binoculars, examine:

◉ All visible roof surfaces systematically
◉ Ridge and hip caps along entire length
◉ Valleys (as much as you can see)
◉ Flashing around chimneys and penetrations
◉ Gutter condition along entire length
◉ Fascia and soffit condition
◉ Any areas of biological growth

Inside your home, check:

◉ All ceilings for stains or changes
◉ Walls near roof edges
◉ Roof cavity access (if safely accessible)

Document what you find:

◉ Date your inspection
◉ Take photos of anything concerning
◉ Note any changes from previous inspections
◉ Create a simple log of findings

This documentation helps you track whether problems are developing or stable, and provides valuable information if you need professional assessment.

What Requires Professional Inspection

Never attempt to:

◉ Walk on your roof without proper training and safety equipment
◉ Make roof repairs yourself unless you're qualified
◉ Access steep or high roofs

Always call professionals for:

◉ Anything you can't safely assess from ground level
◉ Problems you've identified that need confirmation
◉ Biennial/triennial scheduled comprehensive inspections
◉ After major weather events
◉ Before property sales

According to Master Builders Australia, proper safety protocols are essential for any roofing work. Falls from roofs cause serious injuries annually—don’t become a statistic.

When to Call Professionals Immediately

Some problems require immediate professional attention:

Call today if you see:

◉ Active leaks (water entering your home)
◉ Structural sagging or irregularities
◉ Multiple tiles or large roof sections damaged
◉ Large sections of ridge caps failing
◉ Any safety hazards

Call within a week if you notice:

◉ New cracks in several tiles
◉ Changes in ridge or hip condition
◉ New rust or corrosion areas
◉ Flashing gaps or damage
◉ Gutter problems causing water issues

Schedule inspection within a month if you observe:

◉ Gradual increases in moss or lichen
◉ Minor surface rust on metal
◉ Aging but not yet failing components
◉ Any uncertainty about what you're seeing

Early professional assessment prevents small problems from becoming emergencies. The cost of inspection is minimal compared to emergency repair costs.

◉ Watch for: Age-related deterioration, period-specific problems
◉ Consider: More frequent inspections on roofs over 40 years old

Modern developments:

(Kingston, Brighton, Blackmans Bay new estates)
◉ Primary concern: Installation quality on newer roofs
◉ Watch for: Problems appearing within first 5-10 years
(often installation-related)
◉ Document: Keep all installation records and warranty information

The Bottom Line: Early Detection Saves Money

Every roofing problem I’ve discussed follows the same pattern: caught early, it’s a manageable repair. Caught late, it’s an expensive emergency.

You don’t need to be a roofing expert—you just need to look regularly, know what’s normal, and recognize when something’s changed.

Your roof protects everything underneath it. Taking 20 minutes quarterly to inspect it from ground level, and calling professionals when you spot concerns, protects that investment and prevents small issues from becoming major expenses.
