Los Alamitos, CA

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

Almost every flat roof problem is a drainage problem wearing a disguise. Standing water finds the one seam that was not welded properly.

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.

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

Single-ply membranes — TPO, PVC, EPDM — are heat-welded or taped at the seams. The seams and the terminations are the whole job.

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

Locally

Close behind that: dry offshore wind that arrives all at once in autumn. Dry offshore wind lifts material that damp coastal air had been holding down. Most wind losses here happen on a handful of nights a year.

About flat roofing here

Do I have to hire anyone?

No. Take the quotes, sit on them, compare them, or throw them away. There is nothing to cancel and nothing owed.

Do you handle commercial buildings?

Yes. Commercial requests go to contractors who do low-slope and flat systems rather than to residential crews. Say so on the property question and it routes correctly.

What time of year is best to re-roof in Los Alamitos?

Here, the long dry run from May to October is the easy window. November through March is when the phone rings hardest, which means less flexibility on dates and less room on price.

Does being near the ocean change what goes on the roof?

Yes. The specification that matters here is metal, not shingle. Ask directly what the fasteners and flashings are made of; in salt air that answer decides how long the roof lasts far more than the brand of the covering.
