J L.: Joseph and his crew did a fantastic job from start to finish. Our ADU unit was completed beautifully, including two bathrooms, a kitchen, and a complete roof replacement. The craftsmanship is excellent, the team was professional and respectful, and the worksite stayed clean. We're extremely happy with the results and highly recommend them!

Flat roof materials we repair
We work with all common flat and low-slope roofing systems used in Los Angeles:
- TPO (thermoplastic polyolefin) — heat-welded seams for flat roofs and ADUs
- Modified bitumen — torched or self-adhering asphalt membrane
- Roof coatings — elastomeric and cool-roof coatings to extend roof life
- Tar and gravel (BUR) — built-up roofing repair and maintenance
Title 24 cool roof requirements
Much of Los Angeles falls under Title 24 energy code requirements that call for cool-rated roofing on flat and low-slope reroofs. We specify Title 24–compliant products — including cool-roof coatings and reflective membranes — that meet the SRI (Solar Reflectance Index) requirements for your climate zone. We verify the requirements for your specific address and jurisdiction.
Common flat roof problems in LA
Flat roofs fail differently than pitched roofs. Watch for:
- Ponding water that doesn't drain within 48 hours after rain
- Blisters or bubbles in the membrane — trapped moisture underneath
- Separating or peeling seams where the membrane meets itself
- Cracked or dried-out flashing around roof penetrations and parapet walls
- Interior water stains, especially around the edges of the flat roof
Frequently Asked Questions
How much does flat roof repair cost in Los Angeles?
The cost depends on the roof size, the type of membrane, and the extent of the damage. Small repairs like seam patches or flashing replacement are a fraction of a full membrane replacement. We inspect the roof and give you a free written estimate with each item listed.
How long does a flat roof repair take?
Most flat roof repairs are completed in one day. A full membrane replacement on a typical garage or addition takes two to three days. We protect the area and clean up daily.
Does Title 24 require a cool roof on my flat roof?
In much of Los Angeles, California's Title 24 energy code requires cool-rated roofing on most flat and low-slope reroofs. The specific SRI requirement depends on your climate zone and the slope of your roof. We verify the requirements for your address and jurisdiction before specifying materials.
Can you repair a flat roof over a living space?
Yes. We repair and replace flat roofs over additions, converted garages, and ADUs — including those with occupied space below. We check the decking, address any moisture damage, and install a membrane system that meets code for your use case.
