Commercial Roofing in Glendale, CA

Your Glendale roof may have a torch-down cap sheet, a single-ply membrane, shingles, tile or metal. Some buildings mix a low-slope main roof with a sloped section over an entry.

If you are not sure what you have, describe what you can see from inside or from the ground. We can help you identify the covering from there.

Next, tell us whether you need a repair, a full replacement or a roof for a new building. The covering, its condition and the work you need shape the scope more than any brand name does. For flat or nearly flat roofs, see our page on flat and low-slope roofing.

Commercial owners often ask for TPO, a plastic roofing membrane with heat-welded seams, and we install it. On a low-slope roof, our first suggestion is often torch-applied modified bitumen, a type of asphalt-based sheet roofing. The better fit depends on your building, your budget and how you plan to handle future repairs.

Our preferred modified bitumen has a reflective white cap sheet, the top layer that sun and rain reach first.

In our experience, TPO usually costs more than modified bitumen, and its repairs are often harder and more costly. We explain the price and repair outlook of each option. Then you choose the system that suits the building.

Commercial roof repair may fit when a leak seems limited to one seam, wall flashing or drain. Replacement may make sense when leaks appear in several places, wear shows across the roof or old patches keep failing. These are possible signs only, so we weigh them against the condition of the whole roof before you choose.

Our commercial roof replacement work covers tear-off, deck repair where needed and a new roof system.

Tear-off can reveal damage to the deck under the old roof. If we find wet or soft wood decking, we repair it before the new system goes on. Ask how your estimate treats any decking we find.

Full replacements come with our ten-year workmanship warranty. Ask for the warranty terms in writing with your proposal.

Putting up a new building? Send us the plans, and we will price the roof from them. Our commercial roof installation page covers roofing for new construction.

Not sure which job you have? Call (424) 842-2249 and describe what you see. We can start with a free estimate.

Send us the full street address, whether on Brand Boulevard, Colorado Street, Central Avenue or elsewhere in Glendale. Also name the person who handles roof hatch or ladder access, such as a property manager. Tell us who should receive the estimate, too.

Check that the property sits inside the City of Glendale, California. The agency with jurisdiction over that address handles its permit review.

A few short notes help when you call. Write down when each leak showed up, where water appeared inside and any past roof work. A sample roof inspection form lists useful headings for that kind of record.

Keep your notes to what you can see from inside and from old paperwork. Leave the roof itself to our crew.

Our free estimate covers the roof work we propose and its price. A detailed written inspection report is a separate paid service for escrow or for an insurer that requires one. We also help owners pull required permits from the City of Glendale, which decides on approval and timing.

The report fee depends on the roof's size and the building's number of stories. Ask us for the current fee and what the report includes. Our commercial roof inspection page explains that service.

Read any written roof proposal for what it includes, what it leaves out and what it promises. The Contractors State License Board's roofing contractor guide also advises putting promises in writing.
