Spray-Applied
Roof Foam.
Seamless. Waterproof. Energy-efficient. A spray-applied roof system that bonds directly to your existing deck, blocks heat transfer, and resists wind uplift in tropical storms. Installed by Premium Foam, our spray foam division.
Roof foam — also called Spray Polyurethane Foam roofing, or SPF — is a spray-applied roof system that bonds directly to your existing roof deck. Closed-cell foam goes on first, expanding to fill every gap, crack, and seam. A protective elastomeric coating goes on top to seal it against UV and weather. The result is a seamless, fully-bonded roof with no gaps, no fasteners, and no cold spots.
Unlike traditional shingle or membrane roofs that rely on overlapping layers and mechanical fasteners, roof foam is one continuous surface. There are no seams to leak, no edges to lift, no penetrations to fail. The foam itself adds R-value to the roof, so the same install that waterproofs your building also dramatically improves its energy performance.
Roof foam isn't right for every roof. It's commercial-grade for residential applications — best for flat or low-slope roofs, metal roofs, and any building where wind, water, or thermal performance is a priority. Standard pitched-shingle homes are usually better candidates for spray foam under the deck plus traditional shingles on top. We'll tell you straight which approach fits your building.
Roof foam.
By the numbers.
Where roof foam
outperforms.
Roof foam isn't a universal solution — it earns its keep on flat, low-slope, metal, and storm-exposed roofs. Three places it consistently outperforms traditional roofing in the Rio Grande Valley.
Flat & Low-Slope Commercial Roofs
Strip centers, warehouses, retail buildings, restaurants — anywhere a flat or low-slope roof is leaking, ponding, or aging. Roof foam goes directly over the existing system in most cases, eliminating tear-off costs and downtime.
→Metal Roofs with Leaking Seams
Metal roofs leak at seams and fasteners as they age. Roof foam encapsulates the entire surface, sealing every leak path at once. We've turned 15-year-old leaking metal roofs into 50+ year systems without removing a single panel.
→RGV Storm-Exposed Properties
Hurricane-prone properties benefit from roof foam's structural bond. There's nothing for wind to grab — no edges, no overlaps, no fasteners. Field-documented to keep roofs intact through Category 3 winds.

RGV roofs face the worst of two climates. Six months of relentless heat, UV, and 100°F days. Then storm season — Gulf-fed downpours, hurricane-force winds, and the occasional named system. Most roof failures in the Valley happen at seams, fasteners, and edges. Roof foam eliminates all three. There's no seam to fail, no fastener to back out, no edge to lift.
On the energy side, the Valley's heat makes the roof the single most expensive surface on most buildings. Reflective coatings on top of roof foam reduce surface temperatures by 50–80°F vs. dark traditional roofs. For commercial buildings with 20,000+ sq ft of cooled space, that translates to thousands of dollars saved every summer.
Five steps.
No surprises.
Roof foam takes one extra step that wall and attic spray foam don't — the protective coating. Same crew, same standards, full documentation throughout.
-
i.
Free Roof Inspection
We come to your building, inspect the existing roof system, identify problem areas, and recommend whether roof foam is the right fit. Inspections typically scheduled within 48 hours.
-
ii.
Surface Prep
Roof foam needs a clean, dry, well-bonded substrate. We pressure-wash, scrape loose material, repair major damage, and prime if needed. Skipping prep is the #1 cause of roof foam failures — we don't skip it.
-
iii.
Spray Foam Application
Closed-cell foam is sprayed in 1–2 inch passes until target thickness is reached. The foam fills every gap, crack, and low spot — eliminating ponding water issues in the same step it insulates.
-
iv.
Elastomeric Coating
Once foam is cured, we apply 2–3 layers of UV-resistant elastomeric coating. This protects the foam from sun degradation and gives the roof its weatherproof, reflective top layer.

Walkthrough + Maintenance Plan
Final walkthrough together. We document the install, photograph the finished roof, and provide a maintenance schedule for periodic recoats — the only ongoing task to extend the roof to 50+ years.
