What Homebuyers Should Look for in a Property’s Roof

Buyers fall for kitchens and light. Nobody falls for a roof. It’s also the part of the house you can barely see during a short showing.

You don’t need to climb a ladder to get a decent read on it. You just need to know where to look, and what the inspection report won’t tell you.

Start With the Paperwork

Ask the seller or listing agent how old the roof is, and whether it was replaced or just repaired. A vague “it’s newer” isn’t an answer. Ask for the invoice, the permit if one was pulled, and any warranty paperwork.

Warranties come with strings. GAF’s standard shingle warranty, for example, can be transferred only once, and the new owner has to notify GAF in writing within a year of the sale. So check the transfer terms before you count on one.

A record of repeated leak repairs in the same spot tells you something too. It can mean the cause was never fixed.

What You Can Spot From the Ground

Walk the full perimeter of the house, and bring binoculars or use your phone’s zoom. Look for missing, cracked or curling shingles, patches that don’t match the rest, and any dip or step along the ridge line, which can point to a structural problem.

Then look at where the roof meets something else. Chimneys, skylights, vents and walls all rely on flashing to keep water out, so damaged or missing flashing at those joints is worth noting.

Check the gutters if you can see into them. A buildup of shingle granules in an asphalt roof’s gutters can mean the shingles are aging.

Go Inside: Attic and Top-Floor Ceilings

The inside can tell you more. On the top floor, look for water stains on ceilings and walls.

If there’s attic access, take a flashlight up. Dark staining on the underside of the roof deck, rusty nail tips, wet or compressed insulation, and daylight showing through the boards can all point to moisture getting in, and are worth a professional’s look.

A freshly painted patch of ceiling in an otherwise older room deserves a question.

Know What the Home Inspection Covers

It’s easy to assume the home inspection has the roof handled. It covers less than you’d think. Under InterNACHI’s standards, an inspector reviews the roof from ground level or the eaves and isn’t required to walk on it, predict how long it will last, or warrant or certify it.

That’s not a knock on inspectors. It just means a general inspection is a starting point. If the report flags anything on the roof, or the roof is clearly older, it’s worth getting a specialist’s opinion during your inspection window.

Bring In a Roofer Before You Commit

A roofing contractor can give you a view a generalist isn’t required to: how much life the roof likely has left, whether problems are repairs or a replacement, and what either would cost. If you’re buying in Sonoma County, for instance, a local contractor such as cornerstone roofing can assess the roof and put a detailed written estimate in front of you.

That estimate is useful in two ways. You can take it to the negotiating table and ask for a price reduction or a seller credit. And you can share it with your insurance agent early. Connecticut’s Insurance Department, for one, notes that insurers may weigh roof age and condition, including missing or cracked shingles, when deciding on coverage.

A tired roof doesn’t have to end a deal. You just want to know about it before you sign, not after closing.
