Protective Flat Roof Coating
Seal the roof you have instead of paying for the roof you don't need yet

A flat roof in Los Angeles does not usually fail because the membrane wore out. It fails at the seams, the parapet flashings and the drains, and it fails after fifteen years of UV rather than fifteen years of rain. A coating addresses exactly that: it goes over the existing roof as one seamless membrane with no seams left to open up.
A coating works on a roof that drains. Where water stands for days after rain, no coating is the answer on its own – the drainage has to be fixed first, which usually means re-sloping to the drain, clearing or adding scuppers, and rebuilding the low spot. We check that during the inspection and tell you honestly if your roof needs that work before anything gets sealed.
There is a second payoff most homeowners do not expect. A white reflective coating drops roof surface temperature dramatically in an LA summer, and the rooms directly underneath feel it. Clients regularly tell us their upstairs finally holds temperature after a coating went on.

2How it runs
Our flat roof coating process
Roof inspection
We walk the roof, probe for soft spots and wet insulation, photograph every seam and flashing, and send you the photos. If the roof is too far gone to coat, we say so – coating a rotten deck is throwing money away.
Clean and repair
Power wash the entire surface, cut out blisters, rebuild failed seams, and replace any saturated insulation we found. Drains and scuppers are cleared and re-flashed.
Reinforce and prime
Fabric reinforcement is embedded at every seam, penetration and parapet transition – the places roofs actually leak. Then the correct primer for your substrate goes down.
Coat and document
Two coats applied at the manufacturer's specified thickness, checked with a wet-mil gauge as we go. You get before-and-after photos and the warranty paperwork registered in your name.
“Another company quoted me twenty-six thousand for a tear-off. Fresh Build climbed up, showed me photos of a deck that was completely fine, and sealed it for under eight. No leak since, and the back bedroom is noticeably cooler in summer.”

Flat Roof Coating questions
The things people ask before they book. If yours is not here, call and ask it.
(213) 375-0868Coating starts around $4.25 per square foot, and a roof that needs repair before it can be sealed runs from $8.50. For a typical 1,200–1,800 sq ft flat roof that works out to roughly $5,200–$11,000 all-in. A full tear-off and replacement on the same roof would usually run $18,000–$30,000, which is why coating makes sense whenever the deck is still sound.
