Can Spray Foam Be Used on Metal Roofs?

Yes—spray foam roofing (SPF) is an excellent solution for metal roofs. At L&L Roofing & Construction, we apply SPF over existing metal panels in Gainesville to seal leaks, improve insulation, and extend the roof’s lifespan without the cost of a full replacement.

Why SPF Works Well on Metal Roofs

• Seals Leaks at Seams & Fasteners: Expands into cracks and gaps that commonly cause metal roof leaks.

• Adds Insulation: SPF provides one of the highest R-values per inch, reducing heating and cooling costs.

• Waterproofs the Roof: Creates a seamless layer over panels, eliminating weak spots.

• Improves Durability: Protective coatings shield against rust, UV rays, and weather damage.

• Retrofit-Friendly: Can be applied over most existing metal roofs without removal.

Benefits for Property Owners

• Avoids costly tear-offs and landfill waste.

• Extends roof life by 20–30 years with proper recoating.

• Reduces noise from rain and hail.

• Strengthens the roof against wind uplift.
