Request a free roofing estimate

We use the details you send to review your roofing request and prepare a free estimate. You can also call and describe the roof instead.

Commercial roofs leak, wear thin and eventually reach the end of their service life. We look at the covering that is on your building now and tell you what it needs.

An owner or a property manager can ask us to take that look. The estimate for the work is free.

What We Handle on Commercial Buildings

Commercial work here means low-slope and flat roofing, plus the sloped sections that sit alongside it.

That includes multi-unit properties and buildings that a property manager is responsible for. Commercial roofing is one part of the roofing we do in West Covina.

If your property is a single-family home, residential roofing is the better starting point.

Commercial Roofs Are Not Always Flat

A commercial building can carry a flat covering, a sloped covering, or both on different sections.

A retail building may run low-slope over the sales floor and sloped tile above the entrance. An office building can carry shingles on the visible elevation and a membrane behind the parapet.

Our commercial range includes tile roofing and asphalt shingle sections, along with standing-seam metal and TPO. Standing seam metal joins its panels with raised seams and concealed fasteners.

On flat and low-slope roofs, torch-down modified bitumen is our preferred system. It is the one we lead with, not the only one we install. The torch that applies it is where the name comes from.

What We Look At on a Commercial Roof

The covering, the flashing details and the decking underneath are what tell us what a roof needs.

An interior stain does not always sit directly under the place where water entered the building. Water can travel along a seam or a decking board. Where it got in is what shapes the repair.

Flashing is the metal that seals roof-to-wall, chimney and valley transitions. It is a leading leak origin.

Earlier repairs matter too. A patch or an added layer changes what is already sitting on the decking. We look at four parts of the roof:

  • The flashing at walls, parapets, curbs and the mounts that carry rooftop equipment.
  • The condition of the decking, because concealed rot can change the scope we quote.
  • The underlayment beneath any tile section.
  • The covering itself, which can differ from one roof section to the next.

Access and How Your Building Is Used

How materials reach your roof, and how the building is used, both shape a commercial roofing job.

Parking, loading areas, gates and shared driveways all shape the route to the roof. Tell us about them when you call, and say whether the way up runs through an occupied unit. It also helps to know what sits under each section, whether that is a warehouse bay, offices or storage.

The same building can be easy to reach on one side and blocked on the other.

Repair or Replacement on a Commercial Building

A repair fixes the failed part and leaves the rest of the covering in place. A replacement takes the whole covering off and puts a new one on.

One failed area on a commercial roof may call for a roof repair rather than a new covering. Damage spread across the whole roof points toward a full roof replacement. What is hidden under the covering does not settle that by itself.

A tear-off removes the existing covering completely, down to the decking underneath. An overlay installs a new layer over the old covering, so the decking stays hidden.

Tile sections have a third option, because the underlayment beneath the tile can be replaced on its own. A lift and relay swaps that underlayment and any damaged decking, then restacks the tile that is still sound.

How Commercial Roof Size Is Counted

Roof size is counted in squares, and one roofing square is 100 square feet.

Squares measure area, and the area they cover is not all open surface. Rooftop equipment sits on curbs and mounts, and every penetration is one more place the covering has to seal around.

The covering itself raises two questions:

  • Whether the existing covering is torn off first or a new layer is installed over it.
  • How many separate coverings the building carries, and how large each section is.

Free Estimates and Paid Condition Reports

The estimate for your roofing work is free. A documented roof condition report for an insurer or an escrow file is a separate paid service.

An insurer or a buyer in escrow may require documented roof condition before proceeding. The fee for that report varies with the size of the roof and the number of stories.

Start With the Exact Property Address

Give us the exact street address, because a ZIP code alone does not settle the city boundary.

91790 and 91791 are West Covina ZIP codes. Buildings on either side of a boundary can share one postal code, so the address settles it.

The city's General Plan names Downtown and Eastland as planning districts. Either name is a useful local reference alongside the street address of your building.

If your property sits outside the city, check the other areas we cover.

Call Us About Your Commercial Roof

Call (626) 593-1910, describe the building and the problem, and ask for your free estimate.

For some existing roofs, we can quote the work from satellite imagery without visiting first. That approach does not suit every roof or every building, so sometimes we come out and look.

New construction works differently, so supply the plans and we quote the roofing from those drawings.

West Covina Roofing Contractor is a division of Home Vision Remodel. We work under CSLB #1112525, and you can confirm that number with the state license board.

You can also send us your building details instead of calling. Include the address and a short description of what the roof is doing.
