Question

What is the best thing to used to repair cracks on your concrete slab roof?

Answer 1

I work at Home Depot in the lumber and building materials department.  If your roof is purely concrete (e.g. no black roof coating) then I would recommend a vinyl concrete patcher.  It has a vinyl component in it that will bond to the existing concrete.  Also, it depends on the size of the crack as well.  You may get away with using the tubes of concrete repair made by quickcrete.  However, I would recommend the vinyl concrete because I know it will work and hold up to the elements.  You may have to work it down into the cracks if they are small, but it should be a sure way to void them coming back.  It is a little more than regular concrete, whereas 80 pound bags of the cheap stuff is 3.22, but this is around 10 dollars for a 50 pound bag.  It is much more money, but worth what you are going to get out of it.  We also sell many roof coatings to seal it as well...... Hope this helps

Answer 2

go to lowes or home depot and ask someone there they will show you what you need

Answer 3

This probably isn't correct, I'm not a builder, contractor, etc. but perhaps sealing with a caulk/silicone etc, and going over it with more cement/concrete to patch? Depends on your climate also...
