Just a quickie (I hope) for all you guys that use them regularly. I have to paint some dormers and have to install roof jacks to get my footing. I have used them before awhile ago and don"t think I did it right. I know they were installed tightly to the roof and worked perfectly, but I screwed them in over the top layer of existing shingles. I used gutter seal to seal the holes and there have been no problems with leakage. I now know that I am supposed to attach them under a layer of shingles. The roof I will be putting them on now have older shingles and I don't think they will flex enough to allow me to lift them. So the question is what are my options? Is making screw holes and filling with gutter seal an ok thing? Thanks for any help folks.

Alton, if the shingles are as brittle as you say, they will break during the install, laying over the roof is an option, then blackjack the nail hole. Also get up into the attic, figure out the rafter layout, and nail into them. One more thing, when you install the jack, take a piece of new roof shingle, cut it into a strip, place it under the heel of the jack, this will keep the jack from diging its heel into the roof . G

DO NOT JUST USE CAULK

Take this from a guy that used to just caulk his pump jack brackets. THEY WILL LEAK, and if the roof is visible the caulking will look horrible. After you take the bracket off pry up the shingle, just enough to put a dab of caulking, and then slip a piece of step flashing all the way up under the shingle

Patrick,

That flashing idea is genius. I'm going to use it next week.
