Reflective Roof Coatings, Flashing Repair & Leak Prevention for San Diego Commercial Roofs
Commercial Roof Coating & Restoration Contractors in San Diego, CA
San Diego roofs face constant sun with very few cloudy days to give them a break, and near the coast they also deal with salt air and nightly marine moisture. Membranes dry out and crack, seams and flashings loosen, and metal edges, fasteners and rooftop equipment curbs corrode. Because rain is rare, small openings often go unnoticed until a winter storm brings water inside. Low-slope roofs on offices, hotels, research buildings, schools and warehouses across the county all 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 flashings and seal the roof with a seamless reflective coating that adds years of service and keeps the building cooler, for far less than a tear-off.
OUR COMMERCIAL ROOF COATING SERVICES IN SAN DIEGO
We restore the common commercial roof types found around San Diego with reflective coatings selected for strong sun and coastal conditions.
Silicone resists UV and salt and tolerates the ponding that follows a storm. After cleaning and repairing the roof, we apply it in one seamless layer at the warrantied thickness for a bright, reflective finish.
TPO, PVC and EPDM roofs are common on San Diego offices and industrial buildings, and years of sun shrink the sheets and loosen the seams. We prime the membrane, reinforce seams and flashings and apply a compatible coating for a new watertight surface.
Spray foam roofs need an intact, UV-resistant top coat to protect the foam from constant sun. We repair damaged foam and recoat it so the roof keeps insulating and shedding water.
Built-up, modified bitumen and cap sheet roofs dry out, crack and blister in the sun. We repair defects, reinforce flashings and apply a reflective coating designed to bond with asphalt roofs.
Not every roof should be coated. Widespread wet insulation or a damaged deck may mean replacement makes more sense, which is why we test for moisture and take cores first and tell you plainly what we find.

San Diego Commercial Roof Coating FAQs
How does the cost of a roof coating compare to a roof replacement?
A coating restoration usually costs much less than a tear-off because the existing roof stays in place. Savings depend on the roof’s size and condition.
How long does a silicone roof coating last?
Usually 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 structurally sound.
When should a San Diego commercial roof be coated?
Almost any time of year. We schedule around the winter storms and start once morning dew and marine moisture have dried off.
Does a reflective roof coating save energy in San Diego?
Yes, especially inland where summer temperatures run higher. A white reflective surface lowers roof temperatures and cooling demand.
Do tenants need to leave during a roof coating project?
No. The work stays on the roof, and we protect air intakes and keep disruption low.
