Why a Spray Foam Roof Beats the Alternatives

One seamless layer, bonded to your roof, often installed right over what you already have — no seams to leak, no costly tear-off.

The case for SPF

What a foam roof does that patch-and-pray can't

SPF roofing goes on as one seamless layer with no seams to leak, and it bonds to concrete, wood, steel, or your existing roof — so we can often install right over what you have and skip the costly tear-off and landfill fees. It's lightweight, adds insulation value on top of your roof, and a reflective coat cuts cooling costs. One material, tapered to drain, sealed tight.

SEAMLESS

No seams to leak

Applied as one continuous, fully-adhered layer — the seams, fasteners and flashings that fail on other roofs simply aren't there.

OVER EXISTING

Skip the tear-off

SPF bonds to most existing low-slope roofs after prep — less cost, less downtime, less waste to the landfill.

INSULATES

R-value on top

You're re-roofing and adding insulation in one step, then reflecting summer heat with a light top coat.

Questions

Foam roofing — FAQ

Can you install a spray foam roof over my existing roof?

Often yes — SPF bonds to most existing low-slope roofs after prep, so we can roof over what you have and skip the tear-off and landfill fees. We'll assess yours first and tell you straight.

Does a spray foam roof add insulation?

Yes — a spray foam roof adds insulation value on top of your roof while it seals it, and a reflective top coat helps cut cooling costs. You're re-roofing and insulating in one step.

Is a spray foam roof heavy — can my building handle the weight?

No — SPF is very lightweight because it is mostly trapped air, so it adds very little load to your building, far less than tearing off and re-roofing with heavier materials or adding another layer. For most structures that is a non-issue, and we confirm it when we assess your roof.
