Roofing in West Covina CA for Repairs, Replacements and Inspections

Roof leak repair and finding where the water gets in

Failed flashing is a leading source of roof leaks, and slipped tile or split shingles let water through.

Water that gets past the covering can travel before it shows. It may follow a rafter or a slope in the deck, then drip a room away. So the stain on your ceiling may mark where the water left, not where it came in.

We trace the leak uphill from that stain and examine the flashing first. Flashing is the metal that seals a roof against walls, chimneys, and valleys. On a flat section we begin with the seams and the low areas where water collects.

A roof repair can be as small as resetting loose tile or patching a few shingles. Larger repairs mean new flashing, a rebuilt valley, or fresh underlayment over the damaged area. A patch holds best when the surrounding roof remains sound, so we check the slopes around it.

Roof replacement tear-offs, decking repairs and tile lift and relay

We replace a roof when the covering has reached the end of its service life across the slopes.

A full roof replacement begins with a tear-off. The tear-off strips the covering down to the deck, the layer of boards that carries everything above.

Rot in that decking is the most common reason a quoted scope changes. Some of it shows from the attic side, and plenty stays hidden until we pull the covering off. We replace the soft boards, and the price of the job moves with them.

Underlayment is the water protection layer beneath tile, and it often fails while the tile is still serviceable. That is when we price a lift and relay of the tile.

We remove the tile in sections, strip the old underlayment and repair damaged decking. Then we install fresh underlayment and restack the tile that remains fit for service. Some pieces break or weather past reuse, so we replace those.

Roof systems we work on

Slope decides which systems can go on your roof, and the current covering guides the repair.

Flat and low-slope sections take torch-down or a single-ply membrane, while pitched slopes take shingle, tile, slate or metal. Each system fails in its own way, so we match the repair to the system overhead.

Residential roofing and commercial roofing come down to the same short list of details. Drainage, seams, flashing and clean detail work decide whether a roof holds. A flat section on a house and one on a warehouse share those same details.

• Asphalt shingle roofing, from a patch on one slope to a full tear-off and re-roof.
• Flat roofing, usually torch-down modified bitumen, heat-welded along overlapping seams.
• Tile roofing in clay and concrete, including lift and relay under tile that is still sound.
• Slate roofing, including repair of broken pieces and new underlayment beneath the slate.
• Metal roofing, including 24-gauge standing seam panels joined by raised seams with hidden fasteners.
• TPO roofing, a single-ply membrane we use on low-slope commercial buildings.

What changes the scope and price of a roof job

Roof area in squares, pitch, access, old layers and the tile we lift set most of the price.

Two roofs with the same footprint can still land far apart on price. A footprint says little about the surfaces above it, so we price from the roof itself. We measure roofs in squares, and one square covers one hundred square feet.

We can quote some existing roofs from satellite imagery, without anyone on site. That gives you a scope and a preliminary number while you are still deciding. Measurements we take at the property can still move that figure.

We take on new roof installation when the drawings already exist. Then we price from that plan set, which supplies the pitch, the area and the details. The plan set replaces the measuring we would otherwise do on an existing roof.

Civic Center, The Mall and the Glendora Avenue neighborhood are three connected downtown neighborhoods.

Asteria is a neighborhood at Rowland and Azusa. Seville at Vincent Place sits near Vincent and Workman.

Woodside Village is inside the city limits. Sunkist Village was the city's first residential subdivision, and it is also a potential historic district.

Shadow Oak Planned Community Development sits in the south of the city. Our work also extends past the city line into the cities around West Covina.

Free estimates and paid roof inspection reports

The estimate is free; a documented inspection report for escrow or an insurer is a paid service.

Start with the free estimate if you are weighing a repair against a replacement. Tell us which way you are leaning when you call or send the form.

A roof inspection report answers a different need, and buyers in escrow may ask for one before closing. Insurers may ask for a report before they renew or write a policy.

That report puts the condition in writing, and its fee follows the roof size and the number of stories.

It helps to know exactly who is working on your roof and under what license. Our California contractor license is CSLB #1112525, and you can check it on the state's license lookup. West Covina Roofing Contractor is a division of Home Vision Remodel.
