Flat Roofing in West Covina, CA

How your flat roof is meant to drain

A low-slope roof is built with a slight fall, so water travels toward a drain or scupper.

A scupper is an opening through a parapet wall that allows water to leave the roof surface. Drains and scuppers remove water only while they stay clear, since leaves, gravel and debris will block them.

A clogged drain, a blocked scupper, settled insulation or a low spot can each hold water in place.

Standing water is a reason to inspect the seams and the outlets, not proof that the roof has failed.

Where water gets into a flat roof

Flashing, the metal that seals roof-to-wall and valley joints, is a leading origin of leaks.

Water can also enter at a seam, around a vent pipe or along a parapet wall. Each of those details interrupts the flat surface and depends on flashing that ties back into the roof.

A flat section can also meet a pitched roof, on a porch or an addition. A transition like that may sit below asphalt shingle roofing or a tile roof.

The flat roof systems we install

Torch down modified bitumen arrives in rolls.

We heat the material with a torch and bond it to the surface below. The visible top layer is a granulated cap sheet, which is the finished surface of the assembly.

Decking is the structural board layer beneath the roof covering. Hidden rot can change the scope we quoted.

A tear off removes the old covering down to the decking, rather than adding another layer over it. Existing layers, wet areas and the condition of the decking decide whether your roof needs one.

Repairing or replacing your flat roof

How much of the system has failed decides between a repair and a full replacement.

A failure limited to one flashing, one seam or one drain often points toward a targeted repair. Widespread splitting, soaked layers and leaks in several places point the other way. Neither outcome is automatic.

Failed decking does not force a full replacement by itself. What matters is how much of the covering and the deck below have failed. We tell you what we found before you decide.

What decides the price of a flat roof job

Roof size, existing layers, the number of stories and the condition of the decking all move the price.

Roofers measure area in squares, and one roofing square equals 100 square feet. Size is only the start, because two roofs of equal area can price very differently.

On a two-story building, access and setup change. Drains, scuppers and wall flashing all add detail work.

Getting a free estimate on your flat roof

The sales estimate is free, and a documented inspection report is a separate paid service.

A buyer in escrow may order that report before closing. An insurer may require one before renewing or writing coverage. The report fee varies with the size of the roof and the number of stories on the property.

Start by telling us the address and what you have noticed inside the building. For new construction, we work from the plans you supply.
