Downey, CA

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

A pitched roof sheds water. A flat roof is a shallow tray that has to be watertight everywhere at once, which is a much harder thing to build.

What best describes your home?

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

Free, and no obligation to 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.

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

Look at the flashing where the flat section meets a wall. That transition leaks far more often than the field of the membrane does.

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

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

Locally

Behind it: the marine layer keeping the north slope damp. Slopes that never get direct sun stay wet for hours after the fog burns off, and that is where moss, lifted shingles and soft decking start.

About flat roofing here

How long does a re-roof take?

A straightforward asphalt roof on an average house is one to three days. Tile, slate and complex rooflines take longer, and weather stops work more often than anything else.

Why three quotes and not one?

One quote is a number with no context. Three gives you a range, and the conversation about why they differ is where you learn what you are actually buying.

Can I stay in the house while it is done?

Most people do. Expect noise from early morning, dust in the attic, and a day where the driveway belongs to the crew.

How long should a roof last here?

An architectural asphalt roof is rated for twenty-five to thirty years and, in this climate, tends to land at the lower end of that. Tile and metal go much further, provided what is underneath them is maintained.
