Roof Coatings, Flashing Repair & Leak Prevention for San Francisco Commercial Roofs
Commercial Roof Coating & Restoration Contractors in San Francisco, CA
San Francisco roofs deal with wind, moisture and salt more than heat. Strong ocean winds lift membrane edges and loosen flashings, fog keeps roofs damp for long stretches, and salt air corrodes metal copings, fasteners and equipment curbs. When the winter storms come, every weak seam and flashing gets tested. Flat roofs on offices, hotels, apartment buildings, schools and warehouses across the city age this way.
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 flashing details and seal the roof with a seamless coating that adds years of life, for much less than a tear-off on a crowded city block.
OUR COMMERCIAL ROOF COATING SERVICES IN SAN FRANCISCO
We restore the common commercial roof types found across San Francisco with coatings selected for wind, moisture and salt air.
Silicone handles ponding water and constant dampness better than most coatings and resists salt and UV. After cleaning and repairing the roof, we apply it as a seamless layer at the warrantied thickness.
TPO, PVC and EPDM membranes shrink and loosen at the seams with age, and wind can lift weak edges. We prime the membrane, reinforce seams, edges and flashings and apply a compatible coating for a new watertight surface.
Spray foam roofs need an intact top coat to protect the foam. We repair damaged areas and recoat with a UV-resistant system so the roof keeps insulating and shedding water.
Built-up, modified bitumen and torch-down roofs are common on older San Francisco buildings, and they crack and blister with age. We repair defects, reinforce flashings and apply a coating made to bond with asphalt surfaces.
Coating is not right for every roof. Wet insulation across large areas or a damaged deck can mean replacement is the better choice, so we test for moisture and take cores first and give you a straight answer.
Our Commercial Roof Restoration Process in San Francisco
Every San Francisco roof project follows five steps, so you know its condition, the plan and the price first.
Roof Condition Survey
We inspect the membrane, seams, edges, flashings, drains and rooftop equipment for wind, moisture and salt damage.
Adhesion Testing
Core samples and pull tests show whether the insulation is dry and a coating will hold.

San Francisco Commercial Roof Coating FAQs
How does the cost of a roof coating compare to a roof replacement?
A coating restoration usually costs a fraction of a replacement because the existing roof stays in place, which also avoids hauling debris through dense city streets.
How long does a silicone roof coating last?
Typically 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, as long as the roof is mostly dry and sound.
When should a San Francisco commercial roof be coated?
Late spring through early fall usually works best. We schedule around fog and morning dampness and aim to finish before the winter storms.
Does a roof coating help with energy costs in San Francisco?
A reflective coating can reduce heat gain on sunny days and helps buildings meet California’s cool roof standards, though savings are smaller than in hotter inland cities.
Do tenants need to leave during a roof coating project?
No. The work stays on the roof, and we protect air intakes and keep noise down.
