Acrylic Cool Roof Recoat on an 11,100 Sq Ft Commercial Building in Huntington Beach
How we repaired a leaking scupper drain, reinforced the parapets and drains, and renewed an aging coated roof with a bright-white, Energy Star rated acrylic cool roof — without tearing anything off or closing the building.
An Aging Coated Roof With an Active Leak
The owner of a commercial building in Huntington Beach's industrial district called our Huntington Beach commercial roofing office: their flat roof's worn coating needed renewing — and they had a leak that couldn't wait.
During our job walk with the owner's team, we documented the problem areas across the roof:
- An active leak at the front scupper drain, directly above the building's roll-up door
- A rear scupper drain that needed sealing and reinforcement
- Parapet walls that needed to be reinforced and brought into the new coating system
- Debris, dirt, and loose gravel in the drains and waterways
- A weathered roof surface due for a fresh reflective coating
Why Huntington Beach Roofs Need Attention
Near the coast, marine-layer moisture, salt air, and strong sun all work on a roof at once. Scuppers, drains, and parapet edges — where water is concentrated — are usually the first places that fail.
A leak over a roll-up door also means water right where people and equipment move in and out of the building.
Repair the Problem Areas, Then Recoat the Whole Roof
A coating only performs as well as the roof underneath it. So we fixed the leak and reinforced every weak point first, then sealed the entire roof under a new white acrylic cool roof topcoat.
Job Walk
Walked the roof with the owner's team to identify problem areas and plan the work so the building could stay open throughout the project.
Clean Drains & Waterways
Removed dirt, leaves, loose gravel, and debris from the drains and waterways.
Field & Parapet Repairs
Repaired fractures, loose seams, and blisters with modified bitumen and flashing-grade sealant, and reinforced the parapet walls, drains, and roof field.
Front Scupper Rebuild
At the leaking front scupper, removed the failed membrane, cleaned and primed the metal drain, and installed new #28 base sheet and modified bitumen — sealed with flashing-grade sealant and polyester fabric.
Rear Scupper Sealing
Sealed the rear scupper drain with flashing-grade sealant and polyester fabric, with membrane repairs where needed.
White Acrylic Topcoat
Applied a premium white elastomeric acrylic topcoat across the roof, including the parapet walls — Energy Star rated and Title 24 compliant.

Why a Recoat Instead of a New Roof?
A coated roof is built to be renewed. When the coating wears, the roof can be cleaned, repaired, and recoated — extending its life again without the cost of a tear-off.
Lower Cost, Less Disruption
The existing roof stays in place. No demolition, no disposal, and no exposed building.
Bright-White & Reflective
The Energy Star rated topcoat reflects sunlight and meets California Title 24 cool roof requirements.
One Continuous Membrane
The coating ties into the repaired drains, scuppers, and parapet walls as a single watertight surface.
A Renewed Cool Roof, Completed September 2026
The building now has a repaired front scupper, sealed drains, reinforced parapets, and approximately 11,100 square feet of fresh, bright-white acrylic cool roof — completed in about 10 days while the building stayed open for business.

Roof Recoating FAQs
Can an existing coated roof be recoated?
Yes. When a roof coating wears, the roof can usually be cleaned, repaired, and recoated rather than torn off — as long as the roof underneath is still sound.
Why fix leaks before recoating a roof?
A coating seals the surface, but it won't fix a failed drain, scupper, or seam underneath it. Repairing and reinforcing those areas first is what makes the new coating last.
Is an acrylic roof coating a cool roof?
Yes. A bright-white acrylic topcoat reflects sunlight, lowering roof temperature. The topcoat used on this project is Energy Star rated and Title 24 compliant. Learn more about acrylic roof coatings.
