Q:Can i use flex seal spray to just cover the damaged boot
by|Jan 23, 2022
3 Answers
Answer This Question

A:  I would not do that. Flex seal deteriorates a lot faster than the pvc rubber boot does. Flex seal is a bandaid where the rubber boot is permanent. 

by|Jan 25, 2022

    A:  Well that all depends. FlexSeal spray is like a paint. It will only works in certain situations. I don't know your damage, so it is impossible to answer your question. There isn't anything special about that boot that would not allow you to use flexseal spray. It is the type damage that will matter. If you have an open gap, meaning there is nothing behind it - a whole, I wouldn't use flexseal unless you get creative and patch it with an innertube, then flexseal. Flexseal is meant to adhere to a surface, not an air gap.

      A:  A spray coating may not work as well as simply sliding another pipe flange and boot over the cracked one until the roof is replaced in a few more years, as the boots crack just a few years before shingles need replacing. I did this for over 5 years with no problem, even though flange was not fastened down. If it blows off from severe storm, just slide another on. Spray coating may not allow expansion/movement without cracking quickly.

        Answer This Question

        A:  This is not recommended for a metal roof. It is designed for a shingle roof. There are other pipe boots for metal that can be sealed to the metal with a butyl sealant and screws.

          A:  No this is not for metal roof installation.  This is the item number  Model# 81840  Internet# 305390940  Store SKU# 1003233651
