Flat roof work in Riverside, CA
Flat sections on an otherwise pitched house are where the leaks are. Additions, porch roofs, and the bit over the garage.

Before you let anybody on the roof
The things worth pinning down on a flat roofing job. A contractor who has not raised them has not looked properly.
- Which membrane, and how the seams are joined
- How the flat section is flashed into adjoining walls and pitched roofs
- Drain, scupper and overflow provision
- Whether water ponds anywhere after rain
- Whether a coating is being sold as a repair
Coatings can buy a sound roof several years. Coating a failed roof buys you a wet roof with a fresh top coat on it.
Look at the flashing where the flat section meets a wall. That transition leaks far more often than the field of the membrane does.
Modified bitumen is the rolled, torched or self-adhered system you see on older flat additions. Cheaper, and shorter-lived.
Locally
Then, less dramatically: sudden dry winds that test every lifted edge on the roof. These winds are not constant, which is the problem. A roof gets nine quiet months and then one night at fifty miles an hour, and whatever was marginal goes.
About flat roofing here
Why does ventilation keep coming up?
It is the most under-sold part of a roof. Trapped heat and moisture shorten shingle life, warp decking, and in cold weather it is what turns snow into an ice dam.
What if the decking is rotten underneath?
Some of it usually is. The important thing is that the price per sheet is agreed in writing before the tear-off, so the conversation on day two is about quantity rather than rate.
Are the contractors licensed and insured?
Contractors have to give us their state licence number and proof of liability and workers compensation cover before they can receive requests. You should still ask to see current certificates yourself before work starts — a licence can lapse between checks.
Does the sun really wear a roof out here?
Yes — heat and ultraviolet, more than rain, set the clock here. Expect the sun-facing slopes to fail years before the shaded ones, and expect a good contractor to point that out.
