Roofing Experts....SPF
So my house is a mid-century house with a very low slope (almost flat) roof. I'm due for a new roof, and looking at different options. had quotes for EPDM, Single-Ply (60mil), and SPF roofing.
The SPF is a BASF product, closed cell foam...would be 2 inches thick, with 3 layers of acrylic and cloth reinforcement on top. The manufacturer is offering a 20 year warranty on it, not prorated. Hard to find any reviews of SPF...that aren't on websites promoting it. Any of you guys have experience with this stuff. EPDM, Single-Ply, or SPF...which route should I be looking?

lots of foam roof problems years ago here in s fla
no idea if it is the same as SPF or even is a BASF product but think the newer codes banned it here are you in a fire danger area ? or wild weather ? I am amazed at pre-dark age teck in roofing the best we have is tar paper over wood with tile on top romans did that 2000+ years ago bahama style 3 layers of a/c plywood screwed and glued like a boat hull is the best for hi winds most just paint the wood with quality paint but s fla codes willNOT allow that you can nail gun up one layer of cdx but then have to use tar paper and a code nail count and the shingles or tile with more nails and the result a good class 4 or 5 cain will blow the whole thing off while the bahama screwed and glued painted roof stays in place Last edited by nota; 04-19-2016 at 08:45 PM.. |

central Indiana. so we get real seasons here. I live in the woods, so I am concerned about penetration from falling debris off trees. ive been getting estimates from commercial roofers. the theory behind spf seems cool, wasn't sure if there were any caveats. I do like the "cool" roof that the TPO (single ply) and the SPF provide, though. also like the insulation properties of SPF.

Climate and pic of existing roof would help.
I've had good experience with EPDM. |

Why not just new cap sheet?

cap sheet is super expensive here, not many people do it anymore (around here, at least...the commercial guys are all going to more greener roof systems). flat roofs are almost unheard of in Indiana...not at all like out west

I have an extremely low slope roof and went with metal. Seemed to be the best value and lifespan of products that will work.

EPDM, but when I did my own roof, I ask my roofer to install torch-down over the flat roof/patio because it was cheap. Torch down on my rental, and it will last 15 years here. I am happy with that given the amount of money I spent on it. I went that route because it never rains in southern CA.

Fabric and coating is pretty tough. It is the fabric reinforcement that imparts integrity. It would be penetrable, but it is easily patched and repaired, you just re coat and reinforce with more fabric and sealer. Maintenance is often just a wash and re coat.
Closed cell foam is also water proof, but I am not sure if you are talking sheets or spray. |

Not sure of style in your area, but I'd frame a roof on top, pick up the pitches, and do a standing seam roof. I don't see how attic space is getting ventilation.... you could add some overhangs (for some soffit ventilation)

I'd do it in Gaco Roof.
I have two small decks on my house done in Gaco Deck, which is the same stuff with a colour tint in it. Three Canadian winters and it's standing up like a champ. I think it has something like a 50 year warranty. Made in USA. If you can't see it do it in white, you'll save big time on air conditioning.
