Roof Systems for San Jose buildings.
Roof systems are reviewed against the existing assembly, slope, drainage, rooftop traffic, and code path. The pages below link to every available route in this part of the site.
Built-Up Asphalt
Built-up asphalt layers felt and bitumen into a thick, redundant membrane, a proven workhorse on older San Jose low-slope roofs where multiple plies and a gravel surface still earn their keep.
EPDM Black
Black EPDM rubber flexes through the valley's daily temperature swings and ages predictably, a low-maintenance pick for Santa Clara County back-of-house roofs where reflectivity isn't the priority.
EPDM White
White EPDM pairs rubber's proven durability with a reflective surface, giving San Jose buildings the thermal toughness of EPDM while meeting California's cool-roof expectations.
Fleeceback TPO
Fleeceback TPO bonds a reinforcing fabric to the membrane for added puncture resistance and a strong fully-adhered bond, suited to San Jose roofs that see heavy foot traffic and wind uplift.
KEE Roof Systems
KEE thermoplastic resists grease, chemicals, and UV better than standard single-plies, making it a durable choice for San Jose restaurants, labs, and plants with punishing rooftop exhaust.
Modified Bitumen APP
APP modified bitumen carries a tough, UV-stable cap sheet that stands up to San Jose's long sun exposure, a heat-welded multi-ply system well suited to valley low-slope roofs.
Modified Bitumen SBS
SBS modified bitumen stays flexible across temperature swings and adds redundant plies, a forgiving low-slope system for Santa Clara Valley buildings that need walkable, resilient waterproofing.
PVC Roof Systems
Hot-air-welded PVC seams form a continuous reflective skin with strong chemical resistance, meeting San Jose's cool-roof code and standing up to the grease and exhaust on restaurant and food-plant roofs.
Silicone Roof Coating
Silicone coating tolerates the ponding water that lingers on San Jose's dead-flat roofs after a winter storm, restoring and reflecting an aging membrane without a tear-off.
Spray Polyurethane Foam
Sprayed polyurethane foam insulates and waterproofs in one seamless pass, filling the awkward slopes and crowded curbs of older valley buildings, then takes a reflective coat for California energy code.
TPO 60 Mil
Sixty-mil TPO is the reflective single-ply standard for valley low-slope roofs, welding into a continuous white skin that meets Title 24 and suits most San Jose offices, retail, and warehouses.
TPO 80 Mil
Eighty-mil TPO adds thickness for tougher wear and longer service life, a heavier reflective single-ply for San Jose roofs facing heavy foot traffic, hail, or demanding warranty terms.
