Things you don’t expect

I have said it before and I’ll say it again. If your not careful in selecting the right roofing contractor you may end up with a roof that looks like the picture below.

This is what happens when you drag your foam hose through wet foam

wet foam

This is what happens when a foam applicator drags the foam hose over wet foam. This kind of thing  does happen from time to time but the real problem here is the fact that it was left like this. Normally you would take your grinder and grind it flat and then apply your coating, apparently this roofing contractor was to lazy to do it right. Kind of makes you wonder what else they didn’t do. Well take a look at the pictures below.

Sloppy workmanship

This picture shows all around bad foam detail. First off they foamed in the A/C condensate line and the A/C electrical conduit. So if for some reason you needed to replace the electrical  or condensate line in addition to hiring an A/C contractor you will also need to hire a roofer. The foam detail is all around bad.

Not enough foam around the base of the pipe

Cracked Pipe

This is really a all to common mistake. 9 out of 10 foam roof leaks are due to a failed penetration or some other component and not the foam it’s self. If they would have put the foam they sprayed up the sides of the pipe around the base of the pipe this wouldn’t have happened. As you can see someone tried to fix this by brushing some elastomeric coating around the pipe and as you can see it didn’t work. The proper way to fix this would be to re-foam the pipe. If you didn’t have the money to hire a roofer to do it you could apply a thik bead of urethane caulking around it. It will be a semi permanent fix. By the way this type of failure is due to settlement and the lack of foam around the pipe.

In a nutshell this property owner paid some one to give them a new roof and then paid someone else to fix their mistakes. And believe me it’s not cheap, had they hired a roof consultant from the very beginning the job would have been done right the first time and would have cost them a lot less than it’s costing them now. Remember that cracked pipe how much damage did it cause inside the structure? How many pipes were failed  like that…. About 9. So remember when you decide to have roofing work done it might be a good idea to at least call a roofing consultant  to see what his fees are you might just be surprised. Or you can roll the dice.
