Flat Roofs and Commercial Roofing
Flat and low slope roofs cover shops, offices, warehouses and plenty of patio covers and additions. We repair leaks, clear drains, and install coatings, torch down and single ply systems that seal the surface and keep the building cooler.

Why Flat Roofs Leak
Water that sits for days breaks down the surface and finds every seam. Ponding comes from clogged drains, sagging decks or a roof that was never sloped right. We clear the drains, fix low spots and seal the seams before anything else.
Coatings for Hot Buildings
A white reflective coating seals small cracks and bounces sun off the roof. On a warehouse or shop that means a cooler building and less strain on the air conditioning. Coatings work on roofs that are still sound underneath. Roofs that are wet through need repair first.

Questions We Hear
Do you work on warehouses?
Yes. We handle low slope roofs on warehouses, shops and office buildings across Norco, Jurupa Valley, Eastvale and Corona.
Can my patio cover be fixed?
Usually. Flat patio covers and additions leak at the joint with the house. We reflash that joint and seal or recover the surface.
