Roof Seal - Lazy vs. Doing it right March 19, 2020, 05:49:37 pm Hi Everyone,I just uncovered our LD and got on the roof for the first time this season. The roof was newly sealed when we bought it 5 years ago. Now there are about 7 cracks in the seal, around 5 inches long each and in the center of the seal, as opposed to the edges. I have searched the forum and have been educated about how to reseal it right - a lot of work and/or money - which gets the Lazy part of me thinking:Can I put this job off by cleaning the roof and applying liberal amounts of the right goop into and around the cracks? The rig sees some rain, but is covered during the wet Oregon winters.Thanks for your thoughts and stay healthy this year... aka boon-dock!Pete

If it is surface only, there is no need to do anything, particularly if the subsurface is pliable. If it is brittle or if the crack penetrates through the caulk, not just on the surface, only then should you need to re-seal, IMHO.Ken F in NM 1 Likes
Re: Roof Seal - Lazy vs. Doing it right Reply #2 – March 19, 2020, 09:30:26 pm If I had to guess, the roof looks like was sealed 10+ years ago, it takes a long time for the screw heads to pop through.I would clean the old sealant well, cover the cracks and screw heads with new polyurethane, let cure and then Eternalbond Tape the seams.Larry 6 Likes

Re: Roof Seal - Lazy vs. Doing it right Reply #4 – March 20, 2020, 12:30:47 pm Thanks everyone for the feedback. Will the eternabond work well over the slightly uneven surface? 3 or 4 inch wide should cover the old sealant. I will inspect in more detail...

With the right tool, the old sealant cuts like butter.Roof seam reseal | FlickrLarry 3 Likes
