Reflective Roof Coatings, Flashing Repair & Leak Prevention for San Jose Commercial Roofs
Commercial Roof Coating & Restoration Contractors in San Jose, CA
San Jose has some of the largest collections of low-slope commercial roofs in California, covering R&D buildings, tilt-up warehouses, data centers, offices and schools. Months of strong sun and hot afternoons dry those roofs out, open seams and loosen flashings, and rooftop equipment adds penetrations that need constant attention. When the winter storms come, every one of those weak spots gets tested.
Many of these roofs can be restored instead of replaced. Presto Restoration has more than 25 years of experience restoring commercial roofs with high-performance coatings. We repair damage, rebuild flashings around equipment and seal the roof with a seamless reflective coating that adds years of life and lowers cooling costs, for far less than a tear-off.
OUR COMMERCIAL ROOF COATING SERVICES IN SAN JOSE
We restore the common commercial roof types around San Jose with reflective coatings chosen for strong sun and winter rain.
Silicone holds up to UV and to the standing water that follows a storm. Once the roof is cleaned and repaired, we apply it in one seamless layer at the warrantied thickness, and its white finish reflects much of the summer heat.
TPO, PVC and EPDM roofs cover many San Jose R&D and industrial buildings, and years of sun shrink the sheets and open the seams. We prime the membrane, reinforce seams and flashings and apply a compatible coating for a new watertight surface.
Spray foam roofs rely on an unbroken top coat to protect the foam from sun. We repair damaged areas and recoat with a UV-resistant system so the roof keeps insulating.
Built-up and modified bitumen roofs crack and blister after years of heat. We repair the defects, reinforce flashings and apply a reflective coating made to bond with asphalt surfaces.
A coating only makes sense on a roof that is still mostly dry and sound. If testing shows widespread wet insulation or a damaged deck, we will tell you replacement is the better choice.

San Jose Commercial Roof Coating FAQs
How does the cost of a roof coating compare to a roof replacement?
Restoring a roof with a coating usually costs a fraction of tearing it off, since the existing roof stays in place. Savings depend on the roof’s size and condition.
How long does a silicone roof coating last?
About 10 to 20 years depending on thickness and warranty, and the roof can often be recoated after that.
Which commercial roofs are good candidates for coating?
Most low-slope roofs, including TPO, PVC, EPDM, modified bitumen, built-up, metal and spray foam, if the roof is mostly dry and solid.
When should a San Jose commercial roof be coated?
Late spring through early fall, so the coating cures well before the winter storms. In midsummer we start at first light.
Does a reflective roof coating save energy in San Jose?
Yes. With long, warm summers, a white reflective surface can lower roof temperatures and air conditioning loads noticeably.
Do tenants need to leave during a roof coating project?
No. The work stays on the roof, and we protect air intakes and coordinate around sensitive equipment and labs.
