Flat & Low-Slope Roofing in Pasadena.

Pasadena flat-roof work is split between commercial properties along Lake, Colorado, and Fair Oaks, and the historic homes in Bungalow Heaven and Madison Heights with original flat sections over additions and porches. Historic-district flat-roof replacements often require materials and edge details that pass CHRD review — not every TPO color qualifies.

Why RAA for Flat & Low-Slope Roofing in Pasadena

The local-roofer details that don’t skip.

Pasadena's separate plan-check office and CHRD review are familiar territory. We pull commercial reroof permits through the city, know which TPO and modified-bitumen colors pass historic review, and document the work to the standards required for tax-credit historic-rehab projects.

What’s included

  • TPO single-ply installation
  • Modified bitumen (cold-applied)
  • Torch-down APP/SBS systems
  • Parapet wall flashing detail
  • Scupper, drain, & overflow detail
  • Penetration boot replacement
  • Cool-roof reflective membrane (Title 24)
  • Drain testing before sign-off

We hired RAA Roofing for our extremely old roof. Their team is in-house which is great and knocked out the whole job within few days. We also got a very competitive price from them. Along the way, they found other problems as well, and we were not charged for those.

AA Roofing did an excellent job on three residential roofs for us. They were professional, on time, and very upfront about all the costs and procedures from start to finish. The price was fair, and the quality of their work was outstanding. I’m very happy with the results and would highly recommend them to anyone looking for a reliable and honest roofing company.

Exceptional Experience with RAA Roofing! I couldn’t be more impressed with the exceptional service provided by RAA Roofing. While preparing to install solar, we reached out to several roofing companies for estimates. Moti from RAA responded quickly and scheduled a visit right away. He arrived on time, was highly knowledgeable and professional, and provided a fair and competitive estimate. Once we signed the contract, the process moved smoothly and without delay. Permits were immediately pulled, and the entire roof replacement was completed well within our solar installation timeline — and just in time to beat a rainstorm. Moti maintained clear and consistent communication throughout the process – from permits and materials used to timelines and the warranties provided. When the job was done, both my wife and I felt complete peace of mind. Not only did the roof look fantastic, but we knew the job was done correctly. Accordingly, if you are looking for a reliable, skilled, honest, and trustworthy roofing company, I strongly recommend RAA Roofing!

From the moment we decided to tear down and rebuild our family home, RAA made the process transparent and reassuring. The quality of workmanship is impeccable, and the project stayed on schedule and on budget throughout.

FAQ

Flat & Low-Slope Roofing in Pasadenastraight answers.

What Pasadena homeowners ask before hiring a roofer.

Do you handle Pasadena Landmark District roofs?
Yes. We've completed multiple roofing projects requiring Certificate of Appropriateness review through Pasadena's Design and Historic Preservation Section, including Bungalow Heaven and Madison Heights.
Can you match original Craftsman roof character?
Yes - we use cedar-look architectural composition shingles for tear-offs of original wood shake, and we know the period-correct clay tile sources.
Which flat-roof system is best for my home?
TPO is the most common modern choice - bright white, energy-efficient, 20-25 year warranty, no fire risk during install. Modified bitumen is similar life but better in retrofit situations where you can't get clean sub-deck. Torch-down is still common on commercial but slowly being phased out residentially.
How long does a TPO roof last?
20-30 years with the heavier mil membranes (60 mil and up), assuming the flashings and penetrations are detailed correctly. Most failures are at the details, not the field membrane.
