SPF and torch down

robert

We spray chopped fiberglass over spf have few never had a problem,chop it and aluminum emulsion on top never had a problem give a ten year warranty on it to boot.

I've seen plenty of PUF in rough shape, but usually the issue is the topcoat. I don't understand why people put acrylics on foam, as even the best gunner can't avoid a birdbath here and there. The key here is the term "applicator error". I don't get 90+ mph winds once or twice per year in my area, but I do see two guys and a truck flying in PUF over wet substrates.

What do you put on foam, Rosco?

Rosco

I'd recommend urethane (I'm a big fan). Acrylics are what you usually see, as price is an issue, but like I mentioned they can't withstand birdbath ponding.

I did a major repair job on a puf with acrylic coating and ceramic granuals. Damn near none of the granuals stuck. We patched each and every penetration then walked every square foot and patched areas with cracks, exposed insulation, or looked thin.

The roof was done all wrong. I was told that they had nothing but problems since day one, and I beleive it. The manufacturer claimed installation error and efused to fix it. The out of state roofer claimed the manufacturer issued a warranty and it was out of their hands. LOL So they had to pay an additional $12k for a local roofer (Me) to fix it. I used solvent based elastomeric roof coating and elastomeric mastic for that repair.


I also heard they over-sprayed a parking lot full of cars. This is a nursing home.

What was the source/cause of the problems, Grumpy?

Grumpy

100% installation error in my opinion. Not only did they foam in a downspout from one upper section to a lower section, but some plumbing soil pipes were turned into roof drains. Yes they sprayed about 8" of insulation in some areas for what reason, I do not know. Furthermore their edge detail left almost a completely exposed edge of insulation. Finally to top it off they used acrylic and there was alot of ponding water since it was a butterfly style roof and everything drained to the center.


The customer asked for a price to "redo" the roof. I told them the only way I could warrant that roof would be to strip it off, which would have been a million dollar project. The other alternative would be to redo all the edge metal and a completely new elastomeric roof coating. That'd still be over a quarter million dollar job... and their roof was plus or minus 5 years old. I think less than that maybe 2 or 3 actually.

Last time I drove by they demolished half of the entire building, which was all 1 story, and are now beginning to build a 2 story section essentially doubling the number of rooms.

If you ever run into this situation again, let me know. We can always find solutions if we look hard enough.

make sure this guy is heavily insured, as soon as he hits the foam with the torch, grab the smores.
