How Often Should a Roof Be Inspected?

Q: How often should a roof be inspected?

Once a year is the right cadence for most homes here, and the best time is early autumn — September or October — before the first storms arrive. Add an inspection after any major wind event, after any work by another trade on your roof, and before you buy or sell a house. Older roofs and roofs under trees deserve twice a year, because debris in valleys and drains is the leading cause of the leaks that are entirely preventable. A real inspection is not a walk around the driveway. It covers penetrations, flashings, valleys, ridges, drainage, the condition of the underlayment where it can be assessed, and the attic where there is access — and it ends with photographs and a plain-language priority list rather than a replacement quote.

Why timing matters more than frequency

San Diego County gets long dry stretches followed by concentrated storms. Everything that will leak in December has already failed by September — sealant has shrunk, boots have split, valleys have filled — but nothing shows because it has not rained.

An early-autumn inspection catches those items when the roof is dry, the schedule is open and the repairs are cheap. The same items in January are emergency calls competing with everyone else's emergency calls.

What a proper inspection covers

On the roof: every penetration and boot, all flashing and counterflashing, valleys and their debris load, ridge and hip details, drip edge and rake metal, the condition of the covering slope by slope, and drainage — gutters, drains, scuppers, and whether water leaves the roof or sits.

Underneath: attic access where available, looking for staining, rusted nails, damp sheathing, daylight, disconnected bath fans and inadequate ventilation. On closed ceilings, moisture readings at any suspect stain.

What you should get from it

A photo report of every issue, each one labelled with what it is and what happens if it is left. A priority list in plain English: fix now, fix this year, watch. And a written quote for anything you want addressed.

What you should not get is a verbal verdict with no evidence, or a replacement recommendation from someone who never lifted a tile.

Special cases

Real estate and escrow: get a roof inspection independent of the general home inspection, because general inspectors rarely walk tile roofs and their reports say so in the fine print.

After solar, HVAC, satellite or stucco work: inspect the penetrations those trades created. After a Santa Ana event: check ridges, hips and windward edges for slipped or lifted material before the next rain.

HOAs and rental property: an annual photo report is the cheapest defence against a dispute about who knew what and when.

Maintenance beats inspection

An inspection only helps if the cheap items get done. Clearing valleys and drains, replacing aging pipe boots on a cycle rather than after a leak, renewing sealant at curbs, and recoating a foam or flat roof on schedule are all small costs that prevent the $1,200–$2,000 repair.

Our inspections are free, which removes the excuse. There is no charge and no obligation, and the report is yours whether you hire us or not.

In San Diego County and along the coast

The inspection calendar in San Diego County is set by two things: the autumn arrival of winter storms and the Santa Ana winds that precede and follow them. September and October are the ideal window countywide, and a post-Santa Ana check is worth doing in the tile neighbourhoods of Escondido, Poway, Rancho Bernardo and Ramona where wind slides ridge and hip tile.

Coastal homes in Carlsbad, Oceanside, Encinitas, Del Mar, Solana Beach and Coronado should be looking specifically at metal — flashing, fasteners, valley corrosion — because salt air works year-round regardless of rainfall. Properties under eucalyptus, oak and pine in Fallbrook, Ramona, Poway and El Cajon need the twice-a-year cadence purely because of debris in valleys and drains.
