Seamless SPF Roofing & Roof Coatings

Spray-foam roofing for low-slope commercial, shop, ag and metal roofs — one seamless membrane that stops leaks and adds insulation, then sealed with a protective coating that you renew instead of tearing off.

Why SPF roofing

One seamless layer that stops leaks and insulates

Spray polyurethane foam goes down as a single seamless layer over your existing low-slope roof — no seams or fasteners for water to find. It adds real insulation on top of stopping leaks, and a protective coating shields it from UV. When it ages, you recoat it instead of tearing it off — a roof that renews for decades.

01 / LEAKS

Stops leaks

Seamless foam self-flashes around penetrations, curbs and seams — the spots where built-up and membrane roofs usually fail.

02 / EFFICIENCY

Adds insulation

You're insulating and re-roofing in one step — lower energy bills on shops, warehouses and ag buildings.

03 / RENEWABLE

Recoatable

Recoat at the end of the coating's life instead of a full tear-off — a renewable roof, not a landfill.

Best for

The roofs SPF fits best

METAL & AG

Metal & ag buildings

Seals rusting seams and fastener leaks on shops, barns and steel buildings — common across our region.

COMMERCIAL

Low-slope commercial

Warehouses, storefronts and flat commercial roofs where ponding and seams are the enemy.

RE-ROOF

Re-roof over existing

In many cases we spray right over the old roof — less tear-off, less downtime for your business.

Coatings

Coatings that make it last

We finish every SPF roof with a protective coating — acrylic or silicone depending on your roof and climate — applied to manufacturer spec. Silicone stands up to ponding water and UV on flat roofs; acrylic is a cost-effective, reflective option. The coating is what you renew down the road to keep the roof going — see our protective & roof coatings for metal, flat and foam roofs.

Questions

Common questions

How long does an SPF roof last?

The foam itself is long-lived; the protective coating is the wear layer. Recoat it at the end of the coating's service life and the roof keeps going — often for decades. Call for specifics on your roof.

Can you spray over my existing roof?

Often yes — SPF can go over many existing low-slope roofs after prep, which saves the cost and downtime of a full tear-off. We'll assess yours and tell you straight.

Do you do metal and ag building roofs?

Yes — sealing leaking seams and fasteners on metal, shop and ag roofs is one of the best uses for SPF. It's a big part of what we do in this region.

How do you maintain an SPF roof?

An SPF roof is low-maintenance: we inspect it, keep drains and penetrations clear, and address any dings. The coating is the wear layer — when it reaches the end of its service life you recoat the same surface instead of tearing off, and the foam underneath keeps going.
