Roof Inspection Checklist: What You Can Check Safely
You can learn a lot about a roof without walking on it. Check from the ground, safe windows, interior rooms, and an accessible attic for missing roofing, visible sagging, damaged flashing, gutter problems, ceiling stains, drips, damp insulation, and other changes. Leave steep or elevated roof access, close flashing inspection, damaged decking, and storm-impact assessment to qualified professionals.
Stay off the roof
This checklist is for what you can see safely—not for proving what is wrong.
Do not walk on the roof. NRCA does not recommend roof access by inexperienced homeowners. If you need to climb, lean out, or cross an unstable surface to get a better look, stop there and leave that part to a professional.
Start outside, from the ground
Walk around the house and look up from the driveway, yard, sidewalk, or street.
- Missing, slipped, lifted, cracked, or obviously damaged roofing.
- A roofline that looks lower, bowed, or different from before.
- Branches or debris on the roof.
- Flashing that looks loose or displaced where you can see it.
- Gutters pulling away, sagging, overflowing, or damaged.
- Downspouts that are disconnected or dumping water where they should not.
- Damaged fascia, soffit, or eave areas.
- New dark areas, stains, or visible changes after a storm.
Binoculars can help. A ladder onto the roof should not be part of the homeowner check.
Use windows if they give you a safe view
An upstairs window can sometimes show a lower roof section much better than the yard can.
- Look for roofing that has shifted or gone missing.
- Check valleys and roof transitions for obvious debris.
- Note visible flashing that looks bent or out of place.
- Take a photo of anything you want a roofer to examine more closely.
Do not climb out a window or step onto a porch roof to improve the angle.
Then walk the rooms below the roof
Look up as you move through the house.
- Brown, yellow, or dark ceiling stains.
- Bubbling, peeling, or softened paint or drywall.
- Active dripping during or after rain.
- Musty smells or areas that stay damp.
- New staining near chimneys, skylights, vents, or exterior walls.
- Changes that appeared after a particular storm.
Write down the room and rough location. A ceiling stain confirms moisture showed up there; it does not necessarily tell you where water entered the roof.
Check the attic only if access is normal and safe
Do not improvise attic access. If there is a proper entry and a stable place to stand or walk, use a flashlight and look from the accessible area.
- Water staining on visible decking or framing.
- Damp or visibly wet insulation.
- Active dripping.
- Musty odors or visible moisture damage.
- Daylight through an opening where you would not expect it.
- Decking that looks sagged or deteriorated.
Do not step between framing members, crawl across concealed framing under insulation, or enter an area that is wet, unstable, cramped, or electrically unsafe.
These checks belong on the professional list
Some questions need close roof access, experience, or both:
- Condition of roofing materials at close range.
- Flashing at chimneys, walls, skylights, valleys, vents, and other penetrations.
- Fasteners, seams, laps, seals, and transitions you cannot see safely from below.
- Soft or deteriorated roof decking.
- Steep, wet, fragile, or edge-adjacent areas.
- Hail or wind damage that needs close examination.
- Drainage details or debris that cannot be reached safely.
- Damage that may affect the repair-versus-replacement decision.
Even a trained inspector may choose not to walk a roof when doing so would be unsafe or could damage the material.
A few notes can make the professional visit much more useful
Write down:
- When you first noticed the issue.
- Whether it followed rain, wind, hail, snow, or another event.
- Where you saw water or damage.
- Whether the problem is changing.
- Previous repairs near the same area.
- Photos taken from the same safe vantage point over time.
You do not need to name the cause. A clear timeline is often more useful than a guess.
What to do with what you found
If nothing looks unusual, keep your notes as a baseline.
A small, obvious maintenance issue may simply need attention. A clear local defect may lead to roof repair. Active leaking, repeated problems, damage in several areas, or anything you cannot assess safely is a good reason for a professional roof inspection.
If water is near electrical equipment, stay out of the wet area and get qualified help for the electrical hazard separately.
