For over 20 years, Allstate Spray Foam Roofing has been the trusted name in Fresno for high-stakes commercial roofing. Our crew is highly trained, an SPFA member, and dedicated to delivering the longest-lasting roofing solutions in California.
We've come a long way from the early days. Today Allstate runs the Central Valley's most modern spray operation — high-tech rigs, computerized proportioners, heated hoses, and a fleet you can't miss rolling through Fresno. The equipment got smarter. The old-school work ethic never changed.
Straight answers for commercial building owners.
With a maintained coating, SPF roofs perform for decades. The silicone topcoat is recoated every 10–20 years, which renews the entire system without tear-off — foam roofs over 30 years old routinely test like new underneath. Full data in our lifespan guide.
New commercial SPF systems typically run $4–$8 per square foot installed; recoating an existing foam roof typically runs $2–$4. See the full 2026 cost guide — and get a firm written bid within 48 hours of your free assessment.
In most cases, yes — blisters, cracks, ponding, and worn coating are repaired or recoated at a fraction of replacement cost. See foam roof repair in Fresno.
Usually yes. SPF installs directly over most existing metal, built-up, and concrete roofs with no tear-off — saving removal and disposal costs while your building stays open.
Yes. SPF has the highest R-value per inch of any roofing material (about R-6.5 per inch), and the white silicone topcoat reflects most solar energy — a major advantage in Fresno's 100-degree summers.
Most commercial installations finish in under a week: about a day of prep, 1–3 days of foam application, and 1–2 days of coating — with your building open for business the whole time, since everything happens from the roof side. See the full installation walkthrough.
For hot-climate flat roofs like the Central Valley, usually yes — SPF has zero seams, built-in insulation at ~R-6.5 per inch, and renews with a recoat instead of a tear-off. TPO's advantage is a lower first bid on simple new-construction decks. Full breakdown: spray foam vs TPO.
It's one of the best uses of the system. Foam seals every seam and fastener head — the places metal roofs leak — and adds continuous insulation in the same application, with no tear-off.
Yes — SPF is the only roofing material where slope can be built into the application itself. We add foam to low spots to re-slope the roof and eliminate ponding permanently. Details on the foam roof repair page.
