  1. easy to apply, able to get product into small crevices

    By SueL

    I applied this product just yesterday to my roof so I don’t yet know if it fixed the problem. If it didn’t, it’s not because of the product, but not knowing exactly where to apply it. Water was dripping from a crack on my living room ceiling along a wall where the roof levels change. There is no obvious problem such as a missing shingle, so I measured the distance of the leak/crack from the outer wall, then on the roof, I applied the product plus/minus two feet of the measured distance at the joint where the siding and shingles meet. What I like about this product is the aerosol application. It is easy to apply into small crevices that I would not be able to do easily or neatly with a caulk gun or paint brush and can of roof tar. With clear color, I didn't have to worry about overspray. There is no mess to clean up like there is with a caulk tube or can of tar and brush. One word of caution is to clear away all debris in the surrounding area because the force of the aerosol might blow debris onto the wet paint so keep some paper towels handy in case you need to wipe it up and re-spray. I wish I would have known about this product for another roof leak next to the chimney. Several chimney and roof repair companies were unable to identify the source of the leak. It still leaked after having the chimney rebuilt (it had loose mortar and was starting to crumble) so I put lots of messy roof tar on the flashing and on a nail that was exposed. The aerosol Leak Seal would have been so much easier to use.
