A roof inspection tells you what's actually happening up there before you buy, sell, renew insurance or just want to know what's ahead of the rainy season. Requesting an estimate is free; an inspection or a certification letter may carry a fee, covered below.
What's prompting the inspection?
Tile roofs get checked for cracked, slipped or missing tiles and how much of the underlayment beneath is still doing its job. Tile can look fine from the street while the felt underneath has already failed; see tile roofing in Los Angeles for more on how that layer works. Shingle roofs get checked for curling, bald or missing shingles and granule loss. Flat and low-slope sections get checked for open seams, blisters, and standing water: under the industry's ponding definition, water still sitting more than 48 hours after rain counts as a ponding problem, not normal drainage lag.
Flashing is where a large share of roof leaks start, and it's easy to miss from the ground. A thorough inspection checks the metal or membrane at every roof penetration: chimneys, skylights, vent pipes and any rooftop equipment.
Clogged or undersized gutters push water back under the roof edge instead of away from the house. It also checks that gutters are pitched correctly, downspouts discharge away from the foundation, and drains on flat sections aren't blocked.
Where the attic is accessible, the inspector looks for daylight through the decking, damp insulation, and staining on rafters. Water often travels along framing before it shows up as a stain somewhere else in the house entirely.
Soft, spongy or sagging decking usually means water has been getting in for a while, even when the surface problem looks minor. It changes whether a section needs a repair or a full tear-out.
| Item | Typical cost |
|---|---|
| General roof inspection | ~$300–$500 |
| Certification letter (separate from the inspection) | ~$75–$200 |
| Example: inspection + 2-year certification, 2,500 sq ft house | ~$650 total |
Ranges reported by published 2025–2026 cost guides (HomeGuide). The inspection and the certification letter are billed as two separate line items, so confirm which one (or both) is included in a quote.
Sending the form to request an estimate is free. The inspection itself, and any certification letter, may carry a fee; the contractor should tell you the price before booking one.
An inspection and a certification are two different documents. The inspection is the condition assessment. The certification is a separate letter, based on that inspection, stating how much useful life the roof has left, and it's usually what an escrow officer, lender or insurer is actually asking for.
In California real estate sales, the most commonly requested version is a 2-year certification, and FHA loan guidelines require at least 2 years of documented remaining roof life before the loan can close. Insurers increasingly ask for a similar letter, sometimes called a "4-point inspection," documenting at least 3 to 5 years of remaining life before they'll write or renew a policy. For more on what a policy actually covers, see our guide to roof insurance in California.
NRCIA, the National Roof Certification and Inspection Association, is a recognized certifying body for this work. An NRCIA-certified inspector appraises the roof's condition specifically for insurance or real-estate purposes and issues the condition and life-expectancy letter that goes into the transaction file.
If you're heading into escrow, a refinance or an insurance renewal and need something in writing, send the form and a contractor will reach out ASAP to talk through what you need and what it costs.
Los Angeles gets nearly all of its rain between November and April, about 92% of the annual total, with February typically the wettest month. Scheduling an inspection in late summer or early fall, ahead of that window, means problems get caught and repaired while the roof is dry and there's room on the schedule. Waiting until the first storm to find out what needs attention means making a decision at the same time as dealing with an active leak. If a repair does turn up, see roof repair in Los Angeles, or, if the inspection points to full replacement, see Roofing Los Angeles for replacement options.
Missing, cracked or slipped tiles and shingles; bald patches where granules have worn off; water still standing on a flat section more than 48 hours after rain, the industry threshold for a ponding problem rather than normal drainage lag; soft or spongy decking; and active staining inside on ceilings or in the attic. Any of these is worth getting looked at before you're mid-escrow or filing a claim, and before the roof's remaining life becomes a question for a guide like roof replacement cost in Los Angeles.
A full inspection covers the roof surface by material (tile, shingle or flat membrane), flashing at chimneys, skylights and vents, gutters and drainage, and any visible attic or ceiling staining. On a pitched tile or shingle roof that also means checking how the underlayment beneath the surface is holding up, not just the tiles or shingles themselves.
Published guides put a general inspection at roughly $300 to $500, with a separate certification letter (if you need one for escrow or insurance) running about $75 to $200 on top. A worked example for a 2,500 sq ft California house runs about $650 total for both. Requesting an estimate is free, but the inspection itself is a paid service.
Missing, cracked or slipped tiles and shingles; bald or curling shingles; standing water on a flat section more than 48 hours after rain; soft or spongy decking; and active leaks or interior staining are the items most likely to get flagged.
It's a separate letter, based on the inspection, stating how many years of useful life the roof has left. California real estate transactions most commonly ask for a 2-year certification, and FHA loans require at least 2 years of documented remaining life before the loan can close. Insurers sometimes ask for a similar letter documenting 3 to 5 years.
No. Most of the inspection happens on the roof and, where accessible, in the attic. Being reachable by phone during the visit is usually enough, though you're welcome to be there.
Late summer or early fall, before the rainy season starts in November. Roughly 92% of LA's annual rainfall falls between November and April, so an inspection ahead of that window catches problems while the roof is dry and repairs are easy to schedule.
For general contracting work, search the company or license number on the CSLB license check for an active C-39 roofing license. For a certification specifically, ask whether the inspector is NRCIA-certified, since that's a recognized standard for condition and life-expectancy letters used in real estate and insurance.
Tell us what's prompting it, a sale, a lender, an insurance renewal, or just wanting to know what's ahead of the rainy season, and a contractor will reach out ASAP to talk through whether you need an inspection, what it costs and what the written report covers.
