Built Up Roofing for Arizona Homes

Built-up roofing is a traditional flat or low-slope roofing system made of multiple layers or roofing felt (or fabric) alternated with bitumen (asphalt or coal tar), and finished with a protective surfacing like gravel, asphalt, or a reflective coating. The key components are:

  • Structural Damage
  • Water Damage
  • Missing Materials
  • Skipped Inspections or Maintenance

RENCO has been my roofing service for over five years. Every year, they come out and do a good inspection to make sure everything‘s great. Recently, I had my roof recoated. It was done in a timely fashion. The service was excellent, which even included the clean-up of the yard afterward. Overall, I couldn’t be happier.”

Built-Up Roofing Process

Installing built-up roofing at RENCO is accomplished by paying close attention to detail:

  1. Inspect and prepare the roof deck – make sure it is clean, dry, and structurally sound
  2. Install insulation (optional) – adhere rigid foam insulation using cold adhesive, hot asphalt, or mechanical fasteners
  3. Lay base sheet – attach a base sheet with nails, adhesive, or embed into hot asphalt
  4. Apply hot asphalt & ply sheets – mop hot asphalt on the base sheets and install the first ply sheet, and repeat
  5. Install flashing – embed roofing felt into hot asphalt around all penetrations
  6. Apply surfacing layer – there are three main options:
  7. Gravel (standard) – broadcast gravel into the asphalt while it is still hot
  8. Mineral surface cap sheet – install a mineral-coated sheet (torch-applied or embedded in hot asphalt)
  9. Reflective coating – apply aluminum or white reflective coating
  10. Seal and inspect – final cleanup and roof integrity inspection
  11. Alternatively, built-up roofing can be installed using a cold process

“Everyone was so kind and honest! They went above and beyond to make sure the job was done correctly, and I was happy. My neighbor highly recommended RENCO Roofing. So glad I went with them. I will absolutely recommend them as well. They cleaned up every afternoon and had a dedicated employee to clean after the project was finished, too. Very friendly and professional!”
