Rancho Santa Margarita, 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.

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
- Whether a coating is being sold as a repair
- Drain, scupper and overflow provision
- How the flat section is flashed into adjoining walls and pitched roofs
- Whether water ponds anywhere after rain
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.
Modified bitumen is the rolled, torched or self-adhered system you see on older flat additions. Cheaper, and shorter-lived.
Locally
The second problem is morning fog that sits on the roof until mid-morning. Damp that arrives every morning and leaves by lunchtime is worse for a roof than rain, because nothing ever fully dries between one and the next.
About flat roofing here
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.
What time of year is best to re-roof in Rancho Santa Margarita?
Practically, the long dry run from May to October. Crews are busiest right after the weather turns — November through March — so booking outside that stretch usually buys you a better date and a keener number.
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.
What does a new roof cost in Rancho Santa Margarita?
Most quotes here for a standard asphalt replacement come in around $12,000 to $25,500. That assumes one layer to remove and sound decking. Every quote you get should say in writing what happens if the decking is not sound.
