I recently moved into my girlfriends house and noticed there are a few pretty bad leaks in the roof. Everytime it rains they have a few rubbermaid tubs to catch the water. In the main area of the house it is shingle roof witch needs to be fixed also but the back where the tar and gravel roof is it is in very bad shape. I was wondering what would be the best product to buy from home depot to patch the roof i say home depot because i have a good friend that works there and gets me really good discounts. i swept off about half the gravel yesterday to look for spots with bad cracks or if i could see any bare wood. i found some cracks so i just patched them with some of that henry’s stuff in the short black bucket. I really need to fix this roof, i have a 2 year old son and i dont like him being exposed to all this mold and mildew ive been seeing. I just need to know whats the best product to use to patch the roof and maybe last a couple years until we can afford a new roof.
