Tar and Gravel Roof in Florida
I know I am biting off more than even my mouth can chew, however ...
I am going to have to be the onsite supervisor for a new tar and gravel roof.
Where can I find the steps and what should each step consist/look like.
What is the final step and what should it look like.
Presently my roof is half done (according to contractor) hoever at 11pm this Friday night I went up on the roof to discover that there are HUGE patches of gravel that is not stuck to the poured hot tar!
I think that I should stop the guy and demand that the gravel SHOULD be stuck/held down by the hot tar.
So, that is about it.
Any and all coaching on this project is gratefully recieved and needed.
Also if my question is deserving of a FAQ lookup, I will do that, if some one could point me in the right direction.
I have heard that tar and gravel is not allowed anymore in Florida due to missile damage caused by flying gravel during hurricanes.
Anywhoo, it is almost impossible to have all of the gravel firmly emedded in hot asphalt and still acheive the required 600 pounds per square foot required as a ballast. The bottom layer of the aggregate shall be embedded, but not all of it. This is acceptable in the industry.
It is a strange thing here in Miami.
No more permits are being issued for tar and gravel, and (get this) one can still put a tar and gravel roof on your home, and, and,... you still need a permit for a roof, but no more permits are being given for tar and gravel.
So, the gravel is coming off, the roof smothed with a think layer of tar. Allowed to set. Then another layer of tar and then 90# paper with a mineral coating (sorta like very fine rock, but not rock)(at least 90#) on that second layer of tar.
Some mess, but correctable.
