La Verne, 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.
- Whether water ponds anywhere after rain
- Drain, scupper and overflow provision
- Whether a coating is being sold as a repair
- Which membrane, and how the seams are joined
- How the flat section is flashed into adjoining walls and pitched roofs
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
Close behind that: wind-blown embers landing in the valleys. Most houses lost to wildfire are lost to embers arriving ahead of the fire, not to the fire itself.
About flat roofing here
What time of year is best to re-roof in La Verne?
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.
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.
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 La Verne?
For a typical La Verne home of about 23 squares, an architectural asphalt re-roof usually lands between $11,500 and $27,500. Tile, slate and standing-seam metal run well above that. The number moves on how many old layers come off, how much decking is soft underneath, and how easily a truck can get to the house.
