TPO, PVC, modified bitumen and built-up systems for commercial and industrial properties throughout Southern California, installed to the manufacturer’s specification so you get the full system warranty.
What we do
Mechanically fastened and adhered TPO and PVC over polyiso insulation and cover board, FM-rated assemblies, hot-air welded seams.
Torch, cold-applied and hot-mop systems with cool-roof cap sheets for flat and low-slope roofs.
We are an approved applicator for GAF, Carlisle, Holcim Elevate and Sarnafil, so we can register 10 to 20 year no-dollar-limit system warranties.
Ground-up commercial roofs on steel deck, recovers over existing membranes where the deck allows, and full tear-offs.
Phased scheduling, resident communication and board-ready documentation for condominium and apartment communities.
Semi-annual inspections, drain and scupper clearing, and seam and flashing repairs that keep a warranty valid.
