Santa Ana, CA

Flat roofs do not shed water. They hold it back.

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

What best describes your home?

Different buildings need different crews, so this is the first thing a roofer asks.

Free, fast, and no obligation to hire anyone.

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
  • Drain, scupper and overflow provision
  • Whether a coating is being sold as a repair
  • How the flat section is flashed into adjoining walls and pitched roofs
  • Whether water ponds anywhere after rain

Modified bitumen is the rolled, torched or self-adhered system you see on older flat additions. Cheaper, and shorter-lived.

Coatings can buy a sound roof several years. Coating a failed roof buys you a wet roof with a fresh top coat on it.

Ponding water is the enemy. Anything still sitting there forty-eight hours after rain is a design problem, and tapered insulation is usually the answer.

Locally

Close behind that: enough salt in the air to matter to fasteners over twenty years. The covering will reach its rated life here. Plain galvanised fixings holding it down will not.

About flat roofing here

Are you a roofing company?

No, and it matters that we say so. We are a referral service, not a contractor. The roofing work, the licence, the insurance and the warranty all sit with the independent company you choose.

Do I need a permit?

Yes, in nearly every jurisdiction a re-roof is permitted work. A contractor who suggests skipping it is telling you something useful about how they work.

How quickly will someone call?

Most requests are picked up the same day, often within an hour. Emergencies are prioritised. If you have not heard anything by the next morning, check voicemail — contractors usually call from a mobile.

Why does ventilation keep coming up?

Because a badly ventilated attic cooks the roof from underneath and takes years off it. Intake at the eaves and exhaust at the ridge, in balance. It is cheap during a re-roof and awkward afterwards.
