Roof Inspection Checklist (Free Download)

A full roof replacement runs $12,000 to $25,000. A neglected leak behind a chimney? That’s $4,000 in drywall-and-mold remediation before you touch the shingles. Catching that same problem early costs 20 minutes and a $15 tube of sealant.

That ratio is why a solid roof inspection is the highest-ROI half hour you’ll spend on your house all year.

Inspect twice a year. Spring after snow melts, fall before leaves fill the gutters. Add a third pass after any storm with hail or gusts over 50 mph. Three checks a year keeps your roof out of the emergency zone.

This guide walks you through ground first, then walls and trim, then the attic, then the roof surface itself — only if it’s safe. Use the order as-is.

Before You Start: The Only Safety Rules That Matter

I’m not going to give you a lawyer’s list of disclaimers. I’m going to tell you what gets people hurt.

Never get on a wet roof. Water turns asphalt into a Teflon slide. Wait 48 hours after rain.

Never work alone. A kicked-out ladder with nobody home means a broken hip and a phone two feet out of reach.

Ladder basics: Level ground. Extend three feet above the roof edge for a handhold. Three-to-one angle rule.

Footwear matters. Slip-resistant shoes. Not sandals, not barefoot.

Pitch over 4:12 or height over 15 feet? Stay off. Use binoculars, a zoom camera, or a drone. A $150 pro inspection is cheaper than an ER copay.

Walking on asphalt shingles on a hot day knocks granules loose. Minimize roof walking.

Step 1: Ground-Level & Drainage Checklist

Start at the bottom because water problems almost always show up here first.

Gutters and downspouts:

• Look for standing water. Gutters should drain freely toward downspouts. Puddles mean sags, clogs, or improper pitch.
• Check for rust, corrosion, or white oxidation deposits on aluminum gutters. That white powder is the metal breaking down.
• Inspect joints and seams — especially at elbows. Separations here turn a gutter into a watering can pointed at your foundation.
• Downspouts should discharge at least six feet from the house. If yours dump right against the foundation wall, you’re inviting basement water.
• Check downspout straps. A loose downspout pulls the gutter away from the fascia, and now water spills behind the gutter onto the roof edge and trim.

Soffit and fascia:

• Walk the full perimeter and look for soft spots, peeling paint, or mold on fascia boards. Every one of those is a sign of gutter overflow or ice damming in winter.
• Check soffit vents for blockages — bird nests, wasp hives, insulation stuffed in from the attic side. Blocked soffits kill intake airflow, which creates ice dams in cold months and cooks shingles in summer.

Ground drainage:

• Water pooling at the foundation means grading is off. That same water is backing up against the sill plate and potentially wicking up into the roof sheathing from below.
• Look for dark vertical stains below downspouts. That’s overflow during storms. It means your gutters are undersized or clogged.

Pro tip from experience: If you see anything green actually growing out of your gutters — moss, grass, a small shrub — that’s not debris. That’s soil. Which means water has been sitting there long enough to become a planter. Clean gutters are not optional.

Step 2: Exterior Walls, Roof Edge, and Penetrations

From a stable ladder — don’t stretch. Move the ladder.

Roof perimeter:

• Check the bottom row of shingles along eaves and rakes. Any lifted or curled tabs? That’s where wind gets a foothold. Once wind lifts the bottom row, it can peel back entire sections in the next storm.
• Look at the drip edge. You want to see a thin metal lip (usually white or brown) hanging over the gutter. If the shingle edge is flush with the fascia or dips below it, water runs behind the gutter and rots the fascia.
• Inspect the starter strip. The first course of shingles should be fully sealed. Torn or missing starter tabs create a direct entry point for driving rain.

Valleys:

• Valleys carry the highest water volume on your roof. Check for missing shingles in the valley path, cracked metal in open valleys, or lifted shingles in closed (woven) valleys.
• Debris accumulates in valleys. Leaves trap moisture against the metal and accelerate corrosion. Clean them out.
• If a valley narrows to a pinch point where it meets a wall, check for kickout flashing or diverter flashing. This single detail — a $10 piece of metal — prevents thousands of dollars in wall rot. If yours doesn’t have it, add it.

Chimneys, vents, and skylights:

• Scan the chimney for cracked mortar, missing bricks, or a loose chimney cap.
• Look at the counterflashing where the chimney meets the roof. Dried or cracked caulk here is the most common chimney leak origin.
• Inspect plumbing vent flashing collars. The rubber gaskets degrade in 7–10 years. This is the #1 source of mysterious DIY attic leaks. A $30 rubber boot replacement prevents a $3,000 ceiling repair.
• Check skylight frames for separated seals or condensation between panes. If you see fog between the glass layers, the seal failed and water is next.

Step 3: Attic Inspection Checklist

The attic is the truth-teller. The roof surface lies to you — the attic never does. Grab a flashlight and spend 15 minutes up there.

Moisture indicators:

• Dark water stains on rafters, decking, or insulation. Mark them with a pencil so you can track if they grow.
• Gently press the insulation between rafters. If it feels crunchy or crumbly, that’s moisture damage. Rot is underway.
• Check the corners where rafters meet the top plate. Mold likes these dark, stagnant-air spots.

Ventilation:

• Confirm ridge vents, gable vents, and powered vents are unobstructed. Insulation shoved over the soffits from the attic side is the most common ventilation killer. It chokes off intake airflow completely.
• Frost on nail shanks in winter means warm humid air is hitting cold roof decking. That condensation drips onto insulation, ruins its R-value, and rusts fasteners.
• On a hot summer day, the attic should feel cooler than the outdoor air. If it’s hotter, you’re cooking your shingles from below. That’s how you lose 10 years of shingle life.

Daylight test:

• Turn off your flashlight at midday. If you see daylight streaming through the roof deck, you have gaps in shingles, decking, or flashing. Trace every single source and tag it.

Decking and structure:

• Walk on the joists only — never between them. Push on the decking between joists. Soft or spongy spots mean waterlogged sheathing that needs replacement.
• Sagging between rafters means the wood has been wet long enough to lose structural integrity.
• Check collar ties and rafters for cracking, especially near the ridge connection. Hairline cracks are normal. Splits you can fit a fingernail into are not.

Insulation:

• Check for even depth. Raked or collapsed insulation is a red flag for rodents or past water intrusion.
• IRC recommends R-49 to R-60 in most climate zones. That’s roughly 16–20 inches of blown-in fiberglass or cellulose. If you’ve got 6 inches, you’re heating the outdoors.

Step 4: Roof Surface Checklist (Safe Conditions Only)

Do this section only if: the roof is dry, it’s a calm day, the pitch is walkable (under 6:12), and someone is with you. Otherwise, binoculars and a contractor.

General field:

• Look for missing shingles — especially after wind or hail events.
• Check for cracked, curled, or buckled tabs. Curled shingles lose their factory seal and become wind sails.
• Bald spots where granules are gone. Exposed asphalt mat means UV damage or hail impact. That shingle is dying.
• Popped blisters are a leak pathway. Unpopped blisters are usually cosmetic, but they don’t stay unpopped forever.

Flashing details:

• Step flashing at wall intersections should be intact and properly laced into the shingle courses. Missing step flashing means water running behind your siding.
• Dormer valleys need complete metal without bends or paint wear.
• Pipe collars need intact rubber boots. Cracked ones leak. Replace them now.

Moss and algae:

• North-facing and shaded planes grow moss and algae. Moss lifts shingle edges and traps moisture beneath.
• Light moss can be treated with a 50:50 water-and-bleach solution sprayed from a garden sprayer. Don’t pressure wash — that blasts granules off good shingles.
• Extensive moss or coverage in valleys means the shingles underneath are already degraded. Plan for replacement.

Hail damage (post-storm):

• Hail bruises look like soft dark spots where the impact shattered the mat beneath the granules. Press gently — if it’s soft and dark, that shingle is compromised.
• Check metal components — vent caps, chimney caps, flashing — for dents. Dented metal confirms hail of sufficient size to damage shingles. If the metal is dented, the shingles are too.

Step 5: Interior Room-by-Room Checks

Water can travel 10–20 feet down rafters before it drips. The leak entry and the stain could be rooms apart.

Top-floor ceilings and walls:

• Brown or yellow discoloration after rain. If it appears and dries between storms, that’s an active leak.
• Paint bubbling or cool spots — trapped moisture expanding behind the paint.
• Corner staining at exterior walls means water is entering through the wall-roof intersection.

Closets and secondary rooms:

• Musty smells in upstairs closets are early leak indicators that everyone misses.

Cracks and nail pops:

• Diagonal cracks near the roofline are usually truss uplift — cosmetic. Water-stained cracks need investigation.
• Nail pops in the top drywall row are common. Moisture rings around them mean condensation or a slow leak.

Seasonal Roof Inspection Schedule

Different seasons stress different parts of the roof system. Calibrate your inspections.

Spring (March–May): Winter damage — ice dams, gutter separation, lost shingles. Check valleys, inspect fascia for rot, clean gutters before spring rains.

Summer (June–August): Heat damage, pest entry, ventilation. Attic over 120°F on an 85°F day means inadequate ventilation is cooking your decking. Treat moss and algae.

Fall (September–November): Drainage prep. Most important inspection of the year. Full gutter flush, clear downspouts, confirm soffit vents are unobstructed before winter.

Winter (December–February): Interior monitoring, ice dam identification. After heavy snow, check ceilings and attic for drips. Icicles at the eaves mean heat is escaping. Never chip ice off shingles — it tears granules and cracks tabs.

When to Call a Professional

DIY inspection catches 80% of problems. The other 20% needs tools you don’t own. Call a pro if:

• You find soft decking anywhere. That’s wood rot beneath the shingles. Not a surface fix.
• Multiple lifted or missing shingles in one area. Usually means failed underlayment.
• Active leaks during rain. By the time water hits drywall, damage has spread.
• Your roof is tile, slate, or metal. One wrong footstep cracks a $15 clay tile.
• Flashing is pulling away from walls or chimneys. Proper repair needs shingle removal in courses. Caulk is a bandage.
• You’re uncomfortable with the height or pitch. Roof work is the #2 cause of homeowner ER visits after ladder falls. Trust your gut.

A good contractor walks you through findings with photos and classifies issues as urgent, monitor, or cosmetic. Red flags: same-day pressure, refusal to document, or inability to explain in plain English.

FAQ

How often should I inspect my roof? Twice per year — spring and fall. Add a third check after any severe storm with hail or winds over 50 mph. That schedule covers 95% of what will go wrong.

Can I do a thorough inspection without actually walking on the roof? Absolutely. Ground-level checks, a ladder, binoculars, and a 15-minute attic visit catch most issues. Walking the roof surface is the least important part and the most dangerous. Only do it if conditions are perfect and you’re comfortable. Otherwise, send a drone or a pro.

What’s the most common thing homeowners miss during a DIY inspection? The attic. Every single time. The roof surface can look perfect while moisture is actively rotting the decking from the inside. The attic never lies. Spend real time up there with a flashlight.

How do I tell a roof leak from a plumbing leak? Timing. Roof leaks appear during or right after rain. Plumbing leaks happen when fixtures run or are constant. Location matters too — roof leaks follow rafters and drywall seams, while plumbing drips usually come from above the fixture. If in doubt, run every fixture for five minutes during a dry day. No new stains? It’s the roof.

Does my homeowners insurance cover a roof inspection? Not for preventive maintenance. Insurance pays for damage, not checking for damage. However, if a storm caused visible damage (hail dents, missing shingles), the insurance adjuster’s inspection is free and part of the claims process. Document everything with photos before they come out.

What does a professional roof inspection cost? $150 to $400, depending on roof size, pitch, and your market. Some contractors offer free inspections if they suspect storm damage — but recognize that a “free inspection” is a sales call. Pay for the independent report if you want unbiased answers.

What should I photograph and document for insurance or repairs? Wide shot of the whole roof area, medium shot of each problem zone, and a tight close-up of each defect. Include a reference object (a quarter or tape measure) for scale. Note compass orientation (south-facing slope, east valley) and the approximate location in rafter-counts from a corner. Good documentation turns a two-hour adjuster visit into a 20-minute approval.
