I have old derbigum roof. The angle hair is showing. Some areas the hair is blowing in the wind and when I press on it the membrane it feels brittle. The field seams are in good condition. The flashing seams are in good condition. But where the membrane makes the transition from cant strip to vertical wall the membrane is starting to split horizontal. I read some other topics but I have a hard time applying coating to old roofs. The slop is good but there are a few areas that pond and of course itÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢s along the drains, crickets and saddle. All coatings that I have seen peal off within two or three years. ThatÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢s with cleaning, priming and then coating.
IÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢m also not a big fan of recover. Never applied a foam roof, seen them after installation and it seems like thereÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢s a lot of maintenance on the top coating.
#1 ÃƒÂ¢Ã¢â€šÂ¬Ã¢â‚¬Å“ Foam applied to a properly cleaned surface. Will it stay in place or become unattached and blister.
#2 ÃƒÂ¢Ã¢â€šÂ¬Ã¢â‚¬Å“ This roof is semi-busy. I know walk pads are good but the HVAC people never stay on them. What is the typical maintenance on the coating on the foam?
#3 ÃƒÂ¢Ã¢â€šÂ¬Ã¢â‚¬Å“ Warranty?
#4 ÃƒÂ¢Ã¢â€šÂ¬Ã¢â‚¬Å“ Two storyÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢s ÃƒÂ¢Ã¢â€šÂ¬Ã¢â‚¬Å“ easy access ÃƒÂ¢Ã¢â€šÂ¬Ã¢â‚¬Å“ 100 sqÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢s
#5 ÃƒÂ¢Ã¢â€šÂ¬Ã¢â‚¬Å“ Cost per sq ÃƒÂ¢Ã¢â€šÂ¬Ã¢â‚¬Å“ Chicago area
Thanks for the input
