Today's Fiasco

Built in 2001, I have not seen so many blisters in a foam roof in quite some time, open blisters.

Leaking like a sieve (when it rains-:))))

“Dale Killer”… :mrgreen:

Leaks like sieve when it rains, huh…

well, that’s not much of a defect in Arizona, now, is it?

it may be a stupid question but what do You attribute the blistering to Dale ?

I never saw a foam roof before, must be a dessert thing. How long does one last compared to other types used in Arizona.

There is no such thing as a stupid question, just stupid people who ask questions. :wink: Kidding of course, I just love that line.

Seriously though, until you experience it, our sun is just simply brutal. It is continuous and direct. Combine that with poor or lazy workmanship and hence, blisters.

The blisters will be all yours for a couple months while I am on a sabbatical----:frowning:

Hope you have fun ole buddy—:smiley:

They last forever if you keep a reflective sealant on the Foam, James.

Like Dylan said, poor workmanship, usually the mix is not set correctly and the foam gets air bubbles, which enlarge with extreme heat from the sun, or the foam is applied over a moist surface, but that is not usually the case here…just piss-poor-work-and-product…!

Just to picky!

It is not a leak.

For the conservationist it is a GREEN SPRINKLER system!

I’ve seen about three residential foam roofs that had holes in them ranging from the size of a dime to a quarter, and once was actually fortunate enough to see what looked like a crow pecking away at one. I’ve seen similar damage to wood roofs, and probably from the same cause, but still not sure why. Maybe it’s just the nutty activity of crows in La-la-land.

Just about everyone I seen down here has blisters or craters where the blisters used to be.

BTW, I can add another installation problem to Dales’ list, see the last picture, in that one they had applied a new thin cover coat over an existing SPF roof, but hadn’t preped the surface so the new application had no “key” you can see the undercoat still has its’ reflective coat applied which the new covering couldn’t adhere to.

try these

Gerry, SPF doesn’t appear to be the type of roof I would want for some reason.

Why is the roof covered with stone?

Is it for ballast, protection, or both.

Dosen’t appear loggical for a roof system.

Hi Marcel.

SPF is a good system if properly applied and maintained (which you never see) the gravel is used for UV protection, but is a bad idea in my experience as wind scouring tends to create damage, also if the roof gets too much foot traffic this drives the gravel into the surface. I also see a lot of mechanical damage caused by HVAC contractors dragging new compressors across the roof.

Thanks, I think sticking with Membrane is the way to go up here.
