We take on repairs to TPO roofs already in place. We are a roofing company in Los Angeles working on homes and commercial buildings. TPO is one low-slope covering we install, and a modified-bitumen cap sheet is another.
TPO roof repairs and replacement
Our TPO work ranges from localized repairs to full replacement. If water is entering a building with a TPO roof, tell us where it appears. A leak confined to one area may be repairable without replacing the whole roof.
If you want TPO installed on a re-roof, we can bid that work. We may also propose a modified-bitumen cap sheet as an alternative.
Whether TPO is the right covering depends on the roof and what you plan for the building. A modified-bitumen cap sheet suits some projects instead.
Assess the roof assembly and condition
The covering in place and the number of layers on the deck set much of the scope. Rot under the covering can change it again.
Tear-off means stripping to the deck instead of laying a new covering over the old one. The layer count feeds that decision. Once the old covering comes off, the deck condition is visible.
A roof can be sound overall with one failed detail, or worn across the whole surface. The actual condition drives what we recommend.
If the roof is tile rather than a low-slope covering, the work is different. Our tile roof underlayment replacement lifts the tile, replaces the underlayment and restacks tile that is still suitable.
TPO and modified-bitumen alternatives
TPO is thermoplastic polyolefin, a single-ply membrane used on low-slope roofs. Heat-welded seams are a characteristic of the material.
The alternative is a modified-bitumen cap sheet. A cap sheet is the granulated top layer of a built-up or modified-bitumen assembly. The product we work with is Polyglass Polyfresko G.
Polyfresko G is a granulated cap sheet for low-slope roofs. It can form part of a multi-ply system with approved base sheets. That build differs from a single-ply membrane.
If a cool roof surface matters for your building, compare cool roof products and climate considerations before choosing. California also publishes a current nonresidential cool roof resource for commercial projects.
What lands on the roof matters too. Oils and grease can stain TPO, and certain chemical exposures can make it weather faster. Concentration, temperature and how much exposure occurs all change the picture.
If anything on your building can release grease or chemicals onto the roof, let us know at (323) 616-1483.
Occupied buildings and coordination
We work on homes and commercial buildings. Tell us who manages the property and how to reach the roof.
Permit requirements depend on the building and the scope of work. If your project needs one, we can help you pull it from the city or whichever authority has jurisdiction. Give us the address, whether the building sits in Los Angeles or one of the cities we serve.
Review the proposal
A sales estimate from us is free, and you can ask for one at (323) 616-1483. A detailed roof inspection with a written report is a separate paid service. The two documents answer different questions.
Ask how the proposal handles what a tear-off uncovers. Deck condition shows up after the old covering comes off. Ask what the scope includes and what it leaves out.
A 10-year workmanship warranty applies to full roof replacement. It does not cover repairs or other services.
Send the building address and what you know about the roof through our contact page. If water is coming in now, call instead.
TPO roofing questions
What is the average cost of a TPO roof?
An average figure would not tell you much, because the scope of the work drives the cost. Roof area, the number of stories and the slope shape that scope. Rot under the covering and the number of existing layers count as well.
What are the downsides of TPO roofing?
Chemical exposure can be a concern on TPO roofs. Oils and grease can cause staining, and some chemicals can accelerate weathering. The risk depends on the substance, its concentration, the temperature and the amount of exposure.
What is flat roofing called?
A low-slope roof may use TPO, short for thermoplastic polyolefin. TPO is a single-ply membrane with heat-welded seams. A modified-bitumen cap sheet is another system, so ask which assembly a flat-roof proposal specifies.
Call (323) 616-1483 for a free estimate on TPO or a modified-bitumen cap sheet. Tell us the property address, building size and any leaks or visible damage you have noticed.
