A roof inspection checklist is a systematic list of the roof, attic, and drainage points a homeowner should examine twice a year — and after every major storm — to catch problems while they still cost $150–$750 to repair instead of $5,000–$15,000 to re-roof. A complete DIY inspection takes 45–90 minutes, requires only binoculars and a flashlight, and can be done almost entirely from the ground and the attic. The checklist below works in any season; for season-specific tasks, pair it with the Spring Roof Inspection Checklist and the Fall Roof Winterization Guide.
How Often Should You Use This Roof Inspection Checklist?
- Twice a year: once in spring (to find winter freeze-thaw and ice-dam damage) and once in fall (to prepare for winter). This matches the guidance in How Often Should I Have My Roof Inspected.
- After every major storm: high winds, hail, or heavy snow load each warrant a walk-around the same week — see Signs of Roof Damage After a Storm.
- Professionally every 2–3 years, or annually once the roof passes 15 years of age. A professional inspection costs roughly $120–$400 and catches what binoculars cannot.
Most of this checklist is performed safely from the ground or inside the attic. If you do climb, read the Roof Safety Guide for Homeowners first, never walk a wet or icy roof, and skip roof walking entirely on tile, slate, or steep pitches.
Exterior Ground-Level Checklist
Walk the full perimeter of the house with binoculars on a dry, bright day. Check off each item:
| Check | What to Look For | Action if Found |
|---|---|---|
| Shingle condition | Missing, cracked, curling, or buckled shingles; gaps in the pattern | Repair promptly — see How to Replace Damaged Shingles |
| Granule loss | Bald or shiny patches; granules at downspout outlets | Monitor; widespread loss suggests aging — see Signs You Need a New Roof |
| Roofline shape | Sagging ridge or roof planes; visible dips | Professional structural evaluation, promptly |
| Flashing (visible) | Rust, lifted edges, gaps at chimney, walls, and valleys | Reseal or repair — see How to Repair Roof Flashing |
| Chimney | Cracked mortar, leaning stack, gaps at flashing, damaged cap | Mason or roofer depending on failure — see Chimney Flashing Repair |
| Fascia and soffits | Peeling paint, rot, water stains, pest holes, blocked vents | Repair and clear vents |
| Moss, algae, lichen | Dark streaks or green growth, especially shaded north slopes | Treat — see How to Remove Moss and Algae from Your Roof |
| Overhanging trees | Branches within 6 feet of the roof surface | Trim back |
| Ground debris | Shingle pieces, granule piles, flashing fragments, nails | Investigate where they came from |
Roof-Surface Checklist
Perform from a ladder at the eaves or, where safe, on the roof. Many items can also be checked with binoculars or a zoom camera.
| Check | What to Look For | Action if Found |
|---|---|---|
| Penetration flashing | Cracked vent pipe boots, loose exhaust hoods, gaps at mounts | Replace boots — see How to Replace Vent Pipe Flashing and How to Seal Roof Penetrations |
| Sealant condition | Dried, cracked, or peeling sealant at flashing edges and nail heads | Re-caulk with proper products — see Roofing Sealants and Adhesives Guide |
| Valleys | Debris accumulation, displaced valley metal, shingle erosion | Clear and repair |
| Ridge line | Damaged or missing ridge cap shingles, lifted ridge vent | Re-fasten or replace |
| Skylights | Cracked glazing, failed sealant, debris dammed on the uphill side | Address early — see Skylight Leak Repair |
| Nail pops | Raised shingle tabs over backed-out nails | Re-fasten and seal |
| Drip edge | Bent, loose, or missing sections along eaves and rakes | Repair — see How to Install a Drip Edge |
| Soft spots | Spongy feel underfoot (deck rot) | Stop walking; professional assessment |
Attic and Interior Checklist
The attic reveals problems weeks or months before they show on a ceiling. Bring a strong flashlight and inspect on a dry day, then again during steady rain if you suspect a leak.
| Check | What to Look For | Action if Found |
|---|---|---|
| Daylight through the deck | Pinholes or gaps visible in the sheathing | Mark and seal from the roof side |
| Water stains | Dark trails on rafters and sheathing; new stains vs old dry ones | Trace uphill to entry point — see How to Find and Fix Roof Leaks |
| Insulation | Wet, compressed, or moldy patches; insulation blocking soffit bays | Dry/replace; install baffles — see Attic Ventilation and Insulation Guide |
| Mold and odor | Black/green patches on wood, musty smell | Fix moisture source; remediate |
| Ventilation performance | Attic much hotter than outdoors; condensation on nails or sheathing | Improve airflow — see Roof Ventilation |
| Structure | Sagging, cracked, or split rafters and trusses | Structural professional, promptly |
| Penetration backsides | Staining around chimney, vents, and skylight shafts | Matches an exterior flashing item above |
| Interior ceilings | Stains, bubbling paint, hairline cracks at ceiling corners | Find and fix the leak before repainting |
Gutter and Drainage Checklist
Roof drainage failures damage fascia, foundations, and basements long before the roof itself leaks.
| Check | What to Look For | Action if Found |
|---|---|---|
| Gutter debris | Leaves, needles, shingle granules filling the trough | Clean — see How to Clean Gutters Safely |
| Gutter slope and mounting | Sagging sections, separated hangers, standing water after rain | Re-pitch and re-fasten |
| Seams and corners | Drips or rust streaks at joints and end caps | Reseal |
| Downspouts | Clogs (test with a hose), crushed sections, disconnected joints | Clear and reconnect |
| Discharge | Water exiting at least 4–6 feet from the foundation | Add extensions or splash blocks |
| Fascia behind gutters | Rot or staining where gutters mount | Repair and check drip edge |
| Ice dam evidence (cold climates) | Bent gutters, ice ridges at eaves in winter | Improve ventilation/insulation — see How to Prevent and Remove Ice Dams |
What Are the Limits of a DIY Roof Inspection Checklist?
A homeowner checklist catches the majority of developing problems, but be honest about its boundaries:
- Don't walk what you can't walk. Steep pitches, wet or icy surfaces, tile, slate, and brittle old shingles are off-limits — binoculars, a zoom lens, or a drone cover most of it. How to Inspect Your Roof details ground-based technique, and When to DIY vs When to Call a Roofer is the honest decision guide.
- Hidden layers stay hidden. Underlayment condition, deck rot under intact shingles, and fastener corrosion can't be seen without lifting material. This is what professional inspections and moisture meters are for.
- Hire a professional when the roof is 15+ years old, after significant hail, before buying or selling a home, or whenever your checklist turns up structural sag, widespread granule loss, or recurring leaks. An inspection report also creates a paper trail that supports warranty and insurance claims — see Roofing Insurance Claims and Warranties.
- Act on findings by priority. Active leaks, exposed underlayment, and structural issues within days; failed sealant and minor flashing within weeks; cosmetic and preventive items seasonally. Typical pricing for what you find is laid out in Roof Repair Costs.

Frequently Asked Questions
How often should a roof be inspected?
Inspect twice a year — spring and fall — plus after any major wind, hail, or heavy-snow event. Add a professional inspection every two to three years, moving to annually once the roof passes 15 years old. Twice-yearly checks catch most problems while repairs still cost a few hundred dollars.
What should a roof inspection checklist include?
Four zones: exterior ground-level checks (shingles, flashing, fascia, roofline shape), roof-surface checks (penetrations, sealant, valleys, ridge, skylights), attic and interior checks (stains, daylight, insulation, ventilation, structure), and gutter and drainage checks (clogs, slope, downspout discharge). Work zone by zone and record findings with photos for year-over-year comparison.
Can I inspect my roof without climbing on it?
Yes — most of a thorough inspection happens from the ground with binoculars, from a ladder at the eaves, and inside the attic with a flashlight. Roof walking adds little for most homeowners and carries real fall risk, especially on steep, wet, or aging roofs. Leave on-roof work to professionals.
When should I call a professional instead of inspecting myself?
Call a professional when the roof is over 15 years old, after significant hail, before a real-estate transaction, or when your own checklist reveals sagging, widespread granule loss, soft decking, or leaks you cannot trace. Professional inspections cost $120–$400 and document conditions for insurance and warranty purposes.
