What outside guidessay it costs
Five cost guides we read put roof foam between about $3.50 and $8 per square foot for a home. HomeAdvisor's total for a whole roof is $7,500 to $18,000.1
Outside ranges, not Lifetime's prices
No neutral source exists here. No government agency or trade body publishes foam roof prices, so every figure above comes from a company that sells or sells leads.
HomeAdvisor and Modernize are lead-generation sites; they earn money by passing your request to contractors. ArmorThane, RoofObservations, and The Roofing Brief are vendors or contractors.34
Short version. Treat $3.50 to $8 per square foot as a rough outside range for a house, and get the real number in writing.
Roof foam, notattic insulation
Searches for spray foam mix two different jobs. This guide covers roof foam, called SPF, which is sprayed on top of the roof and sealed with a UV coating.6
Attic and wall insulation sits inside the house and is priced as a different job. Those per-square-foot figures don't apply to a roof.
What moves theprice up or down
Quotes differ for three reasons: how thick the foam goes, which coating sits on top, and whether the old roof stays or comes off.2
- Foam thickness. The industry guide calls for at least 1 inch of foam.6 HomeAdvisor prices foam by density, from $0.30 to $1.50 per square foot for materials.1
- Coating type. HomeAdvisor lists silicone topcoat at $1.40 to $2.50 per square foot and acrylic at $0.15 to $0.75.1 The coating should reach 20 to 40 dry mils.6
- Old roof removal. Outside guides add $1 to $3.50 per square foot when the old roof must come off.24
- Permit. HomeAdvisor lists $250 to $500 for a foam roof permit, as a national figure.1
Ask any quote you get whether it includes removal, how many inches of foam, and which coating. Those three answers explain most gaps between two bids. Our roof coatings page covers the coating side.
The recoat isa cost too
A foam roof needs its coating renewed about every 10 to 20 years, and maintained foam roofs can last past 30 years.6 Outside guides put the recoat at about $1.50 to $4.50 per square foot.5
At Lifetime Roofing of El Paso, the lifetime warranty covers our workmanship. A recoat on schedule is normal upkeep, and the owner pays for it.
Be careful if a roofer says a recoat is due. Ask them to show you the worn coating, and to find the leak first if there is one. Our elastomeric roof coating guide explains how coatings wear.
