How often should you have your roof inspected, and what does an inspection cover?

An inspection is worth having on a schedule and worth having after a storm, and those are two different inspections. Here is what each one should produce, and what it should cost you.

The short answer

How often should a roof be inspected?

Twice a year on a roof past 15 years, once a year before that, and always after a wind or hail event in your postcode. Ours costs nothing: the inspection, the measurement and a 20-plus photo report are free and yours to keep. Home-inspector and engineering reports typically run into the hundreds.

What a proper roof inspection actually covers

A walk round the house with a pair of binoculars is not an inspection, and neither is a photograph of one slope. These are the things a report should have looked at and named.

  • Every plane separately. Roofs age unevenly. A south-facing plane can be finished while the north one has a decade left, and a single overall verdict hides that.
  • The field surface: granule loss, curling, cracking, bald patches, blistering, and whether shingles are still sealed to the course below when lifted by hand.
  • All the details: valleys, drip edge, step and counter flashing, the chimney, pipe boots, exhaust caps, skylight perimeters and any wall-to-roof intersection. This is where the leaks are.
  • Ventilation: intake at the soffits, exhaust at the ridge, and whether the two are balanced or working against each other.
  • The deck, by feel and from the attic: soft spots underfoot, sag between rafters, daylight, damp insulation, dark staining and rusty nail shanks.
  • The gutters and the ground: granule accumulation, dents from hail, where the downspouts discharge.
  • Corroborating evidence off the roof: soft metal on the property — vent hoods, the air-conditioning condenser fins, the garage door, fencing. If none of it is dented, be sceptical of anyone telling you the roof is destroyed by hail.

What you should be handed at the end: photographs, slope by slope, of what was actually found, with the date. Not a verbal summary, not three stock photos, and not a number with no evidence attached. Our report is yours whether or not you hire us, including when the finding is that nothing needs doing.

What a roof inspection costs

The kinds of roof inspection, and what each is for.
TypeCostWhat it is for
Contractor condition inspectionFree from us, and free from most reputable contractorsCondition, remaining life, and a scope if work is needed. This is the one most homeowners want.
Storm or claim inspectionFree from usDocumenting dated, photographed damage by mechanism, so a claim is decided on evidence rather than argument.
Home inspector, roof sectionPart of a full home inspection feePoint-in-time condition for a property transaction. Usually from the ground or a ladder, and rarely a walk of every plane.
Engineering or forensic reportSeveral hundred dollars and up, paid by youA written opinion by a licensed engineer, used where a claim is disputed or a structural question exists.
Drone surveyIncluded in ours where it is usefulPhotographs of a roof too steep, too high or too brittle to walk. Good for imagery; no substitute for lifting a tab by hand.

A word on drones, because homeowners ask. Aerial imagery is genuinely useful on a steep or fragile roof and it produces the pictures that make a claim legible. What a drone cannot do is lift a shingle to see whether the seal is still bonded, feel a soft deck underfoot, or look at the underside of the sheathing. A broken thermal seal is the most common wind damage there is and it is invisible from above. So a drone-only inspection is an incomplete one, however good the photographs are.

When to book an inspection

  • Once a year on a roof under 15 years old, ideally in autumn before the freeze-thaw season.
  • Twice a year past 15 years, and after every winter.
  • After any wind or hail event in your area, whether or not you can see anything. Most carriers have a reporting window and the evidence gets harder to attribute the longer you leave it.
  • Before you list the house. A roof finding in a buyer inspection costs more in negotiation than it does to deal with in advance.
  • Before a policy renewal if the roof is past 20, because roof age is increasingly what drives a carrier decision in this market.
  • Whenever a stain appears on a ceiling. That is not a schedule, that is now.
Red flag — an inspection that is a sales visit“Free inspection — we just need you to be there to sign the paperwork afterwards.”

A free inspection is normal and good. A free inspection that requires a signature at the end of it is a sales appointment wearing an inspection badge. There is nothing to sign at an inspection; there is a report to read.

Ask instead: What am I signing, and can I have the photo report without signing anything?
Red flag — damage nobody will photograph“It is bad up there, you would not believe it. You need a full replacement.”

If it is that bad it photographs easily. A verdict with no imagery is not a finding, and the reason it matters here is that the same visit usually ends with a price. Evidence first, price second.

Ask instead: Please send me the photographs of each slope before we discuss any number.

Roof inspection questions

How often should you get a roof inspection?

Once a year on a roof under fifteen, twice a year after that, and always following a wind or hail event in your area. Autumn is the better single slot in Maryland because it puts any repair in before the freeze-thaw cycles that widen every small opening. Add an inspection before listing a house and before a policy renewal on a roof past twenty, since roof age is increasingly what drives a carrier decision here.

How much does a roof inspection cost?

Ours costs nothing. The inspection, the measurement and the photo report are free and yours to keep whether or not you hire us, and there is no inspection fee and no consultation invoice. Paid alternatives exist for different purposes: the roof section of a home inspection is part of that inspection fee, and a licensed engineer forensic report for a disputed claim runs into the hundreds and is paid by you. What you should never pay for is a contractor coming to look at a roof he hopes to sell.

What does a wind damage roof inspection look for?

Broken sealant bonds first, because that is what wind actually does. An inspector lifts tabs by hand across each plane to see whether they are still bonded to the course below, and looks for the sharp horizontal crease left where a shingle folded back and reseated. Then the edges and corners, where uplift is highest: bent drip edge, a wavy rake line, ridge caps lifted at one end. Then everything that is not the roof — fencing, screens, siding, gutters — because damage elsewhere corroborates that something happened.

Can a roof be inspected with a drone?

Partly, and it is genuinely useful on a roof that is too steep, too high or too brittle to walk safely. Aerial photography documents missing and displaced material well and produces imagery that makes a claim legible. What it cannot do is lift a shingle to test the seal, feel a soft deck underfoot or inspect the underside of the sheathing from the attic, and broken seals are the most common wind damage there is. Treat a drone as a camera, not as the whole inspection.

Should I get a roof inspection before buying a house?

Yes, separately from the general home inspection, if the roof is past about fifteen years or the general inspector flags anything. A home inspector assesses the whole house and typically looks at the roof from a ladder or the ground; a roofing contractor walks the planes, lifts material and checks the attic. The difference matters because roof age drives both the insurance position and a five-figure future cost, and both are things to know before closing rather than after.

What happens if the inspection finds nothing wrong?

You get the report and we go away. A meaningful proportion of the roofs we look at do not need anything doing, and saying so in writing is the point of putting the finding on paper rather than in a conversation. It also gives you a dated baseline: a photographed record of the roof today makes the next storm claim considerably easier to argue, because the before is already documented.
