Safety first. Most items can be checked from ground level using binoculars. Only access the roof if you are comfortable doing so safely, have appropriate footwear, and never work alone. If in doubt, hire a professional.

A — Exterior & Ground Level Inspection
Can be completed safely from ground level
0 / 0
Roof Surface — Shingles
No missing or displaced shingles Missing shingles expose the roof deck to water ingress immediately
No cracked or split shingles Thermal movement or impact damage — allows water under the surface
No curling or buckling shingles Edges curling up (cupping) or middle buckling (clawing) indicates moisture damage or aging
No blistering or bubbling shingles Caused by poor ventilation or manufacturing defects — reduces waterproofing
Granule Loss
Minimal granules in gutters Excessive granule loss in gutters indicates the protective layer is depleting — a sign of end-of-life shingles
No bare patches visible on shingles Dark bare spots mean the asphalt is exposed to UV — replacement is likely needed
Flashings & Penetrations
Chimney flashing intact — no rust, gaps or lifted edges Chimney flashing is the #1 cause of roof leaks — check step flashing and counter flashing separately
Pipe boot / plumbing vent flashings not cracked Rubber neoprene pipe boots degrade in UV and crack after 10–15 years — a very common leak source
Valley flashings secure and undamaged Valleys channel high water volume — open or rusted valley flashing leads quickly to interior leaks
Roof vent flashings sealed — no gaps around collars Check sealant around all vent collars for cracking or separation
Chimney & Masonry
Chimney mortar joints intact — no crumbling or gaps Deteriorating mortar allows water into the chimney structure and the roof below
Chimney cap present and undamaged Missing or cracked cap allows rain directly into the flue and down into the firebox
Structure & Vegetation
No sagging ridgeline or uneven roof planes Visible sag indicates structural issues with rafters or decking — requires immediate professional assessment
No moss or algae growth Moss retains moisture and lifts shingles. Black algae streaks (Gloeocapsa magma) degrade shingles over time
No lichen (grey-green crusty patches) Lichen bonds to shingle surface — professional chemical treatment required, mechanical removal causes damage
Gutters & Downspouts
Gutters clear of debris and flowing freely Blocked gutters cause water to overflow and back up under the roof edge — a major cause of fascia rot
Gutters securely fastened — no sagging sections Loose gutters pull away from the fascia and direct water against the wall
Downspouts draining away from foundation Water pooling at the foundation causes basement flooding and structural damage — extensions should discharge at least 6 ft away
B — Interior & Attic Inspection
Inspect from inside the attic with a torch
0 / 0
Light & Water Intrusion
No daylight visible through roof deck Beams of light coming through the decking mean there are gaps large enough for water entry — urgent repair needed
No water stains or dark patches on sheathing Dark staining on roof decking indicates past or ongoing water intrusion — trace the source carefully
No active dripping or wet surfaces Any active leak during or after rain is an emergency — call a professional immediately
Mold & Mildew
No mold or mildew on rafters or sheathing Mold growth indicates persistent moisture — source must be found and fixed before mold remediation
No musty or damp smell in attic space Persistent damp smell even without visible mold may indicate moisture trapped in insulation
Ventilation
Soffit vents unobstructed and clear Blocked soffit vents prevent air intake — leads to heat and moisture buildup that degrades shingles from below
Ridge vent functioning — air flowing from soffit to ridge Proper cross-ventilation extends shingle life by up to 25% and prevents ice dams in cold climates
Roof Deck Integrity
No sagging or soft spots in roof deck Soft spots when walking the attic floor indicate rotted decking — structural repair required before re-roofing
No visible wood rot on rafters or decking Rot spreads rapidly once moisture enters — discoloured, soft, or crumbling wood needs immediate attention

How to inspect your roof yourself

Most of a roof inspection can be done safely from the ground. Follow these steps in order — use the interactive checklist above to record your findings as you go.

1

Gather your equipment

You need: binoculars (essential for ground-level inspection), a smartphone or camera for photos, a torch for the attic, and a notepad or the PDF from our checklist above. Wear non-slip shoes if you plan to access the roof.

2

Safety rules before you start

Never inspect a roof alone. Avoid working in wet, icy or windy conditions. If your roof pitch is steep (more than 6:12) or you are not confident at heights, inspect from ground level only. A $200 professional inspection is far cheaper than an ER visit.

Most of the 27 items in our checklist can be assessed from ground level with binoculars. You do not need to go on the roof to complete a useful inspection.
3

Do the ground-level walk-around

Walk slowly around the entire perimeter of your home, looking up at each roof section. Use binoculars to check shingle condition, ridge lines, flashings around the chimney and pipes, and any visible moss or dark streaking. Photograph anything that looks unusual.

4

Check the gutters and downspouts

Walk the gutters and look for: debris buildup, granules in the gutter (a sign of shingle aging), sagging sections, separated joints, and downspouts that discharge water too close to the foundation. Flush a downspout with a hose to confirm it drains freely.

5

Inspect the attic

On a bright day, go into the attic with all lights off and look for beams of daylight — any visible light means a gap large enough for water entry. Then switch your torch on and inspect the sheathing for dark staining, mold, soft spots, and signs of rust on any metal components. Check that soffit vents are clear and smell for mustiness.

6

Record and photograph everything

For each issue found, photograph it from multiple angles and note its location (e.g. “north-facing slope, second valley from chimney”). This makes it much easier to describe to a contractor and ensures you get an accurate quote. Use the Download PDF button in our checklist to generate a formatted report.

Professional inspection

When to call a professional roofer

A DIY inspection is a great starting point, but there are situations where a licensed professional is essential — and trying to self-assess can delay urgent repairs.

Urgent

You have an active interior leak

Water staining on ceilings, dripping from light fixtures, or damp patches on walls indicate a breach that is already causing damage. Call a professional immediately — every rain event that passes without a repair extends the damage and increases the cost significantly.

Before they arrive: photograph the leak location, place buckets, and note whether it happens during rain, after snow melt, or constantly.

Act soon

You find significant granule loss, broken tiles or widespread damage

Granules in the gutter after every rain, multiple cracked or missing shingles, or widespread moss and lichen growth are signs the roof is approaching end of life. A professional can assess whether targeted repairs will extend its life or whether a full replacement is more cost-effective.

Ask for: a written report with photos, a clear itemisation of repair vs replace costs, and a timeline recommendation.

Recommended

You are uncomfortable or cannot safely access the roof

There is no shame in hiring a professional for the inspection itself. Most roofing contractors offer inspections for $75–$200, and many offer free inspections as part of a cleaning or repair quote. If you are buying or selling a home, a professional inspection is strongly recommended regardless of what a DIY check shows.

What to ask for: a written report, photo documentation, and an indication of remaining roof lifespan based on current condition.

By roof type

Roof inspection checklist by roof type

Different roof materials have different failure points. Here’s what to focus on during your inspection based on your roof type.

Shingle roof inspection

Asphalt / fibreglass shingles

Asphalt shingles typically last 20–30 years. The most common failure points are granule loss, curling edges, and cracked pipe boot flashings — all of which can be spotted during a careful ground-level inspection.

  • Check granule buildup in gutters — consistent loss means end-of-life shingles
  • Look for “cupping” (edges curling up) or “clawing” (middle buckling) — both indicate moisture issues
  • Inspect pipe boots around plumbing vents — rubber cracks after 10–15 years
  • Check that ridge shingles are lying flat and haven’t lifted
  • Look for dark streaks (algae) or green patches (moss) especially on north-facing slopes

Metal roof inspection

Standing seam, corrugated & metal tile

Metal roofs last 40–70 years but have unique failure points. Fastener backout, seam separation, and surface rust at cut edges are the main concerns — easily missed without knowing what to look for.

  • Look for exposed fastener heads that have backed out from thermal expansion
  • Check panel seams for separation or sealant failure at overlaps
  • Inspect cut edges around penetrations and gutters for rust streaking
  • Check that panel clips haven’t restricted thermal movement — causes oil canning
  • Inspect painted surfaces for fading, chalking or peeling — affects weather resistance

Flat roof inspection

TPO, EPDM, modified bitumen & built-up roofing

Flat roofs are particularly vulnerable to ponding water and membrane damage. Drainage is the single most important factor — any water sitting on the roof for more than 48 hours after rain is a problem.

  • Check for ponding water — low spots indicate structural deflection or inadequate drainage
  • Inspect membrane for blistering, bubbling or delamination
  • Check roof drains and scuppers are clear and flowing freely
  • Look at seams and lap joints for separation — these are the primary leak points
  • Inspect penetration flashings for membrane pull-away or sealant failure

Commercial roof inspection

Large commercial & industrial roofs

Commercial inspections are more complex due to HVAC equipment, parapet walls, and larger roof areas. A professional commercial roof condition inspection form is recommended for formal assessments and insurance purposes.

  • Inspect HVAC unit bases and curbs for membrane damage from vibration
  • Check parapet walls and copings — a leading source of water entry on commercial buildings
  • Inspect expansion joints for sealant failure or membrane tearing
  • Check roof access hatches for proper sealing and membrane integration
  • Document all penetrations, drains and equipment with photos for the inspection report
Frequently asked questions

Roof inspection — common questions

How often should a roof be inspected?

Twice a year — once in spring to assess any winter damage, and once in autumn before the wet season. You should also inspect after any major storm event (hail, high winds, heavy snow) regardless of the regular schedule. For roofs over 15 years old, an annual professional inspection is recommended even if no issues are visible.

Can I inspect my roof myself?

Yes — most of a useful inspection can be done safely from ground level using binoculars. Our free checklist above covers all 27 key inspection points and most can be assessed without setting foot on the roof. A DIY inspection is a good way to identify obvious issues and decide whether to call a professional. For a full structural assessment, buying or selling a property, or any insurance claim, a licensed professional is strongly recommended.

How long does a roof inspection take?

A professional inspection typically takes 45–90 minutes for a standard residential property. Larger homes, complex roof designs, or those with multiple issues to document take longer. A written report with photos usually follows within 24–48 hours. A DIY inspection using our checklist takes around 30–45 minutes including the attic check.

What does a roof inspection report include?

A professional roof inspection report should include: written findings for each inspection zone (exterior, flashings, gutters, attic), photographs of all identified issues with location notes, a severity rating for each issue (minor, moderate, urgent), recommended actions and estimated timelines, and an overall remaining roof lifespan assessment. Our free interactive tool generates a basic version of this report which you can download as a PDF.

Is a roof inspection worth the cost?

Yes. A $150–$300 professional inspection regularly identifies issues — cracked pipe boots, failed flashing sealant, early moss growth — that cost $100–$500 to fix proactively but can cost $5,000–$20,000 if left until they cause interior water damage. The inspection pays for itself if it catches even one issue that would otherwise go undetected. For homes over 15 years old or before buying or selling, the ROI is particularly strong.

Do I need a roof inspection before selling my home?

It is not legally required in most states, but it is strongly recommended. Buyers routinely request a roof inspection during due diligence — discovering issues at that stage gives you no time to fix them and can result in price reductions, repair credits, or deals falling through. Getting a pre-listing inspection lets you fix issues on your own timeline and price the home accordingly, removing a common negotiation lever for buyers.
