EPDM Rubber Roof Maintenance and repairs

Hello All--I know about the use of butyl tape under skylights, vents, etc and self leveling sealant over all seams, edges, vent/skylights edges, over screws, etc.

Am I correct with the above? Am I missing something?

I think you have that down. What I have seen on older rigs (mine is a 2001) is that many owners simply pile more lap sealant over the existing without consideration of its integrity. Unfortunately, the old sealant often needs to be removed before adding new. As an example...the sealant on my skylight looked OK but in reality the under coats were loose and allowed for leakage. The picture shows how easily the sealant came off the roof.



I wanted to know, as I have heard of some folks doing this, but is it recommended to cover the entire roof with a roll on, paint-like finish that seals and protects entire roof? It sounds logical, especially for older EPDM rubber roofs like mine. However, I do not want to do something to diminish or be harmful to the rubber roof material.

Most people are not supportive of using these coatings preferring a complete new membrane installation. I plan on using one of these in a year or two. The product I am considering is Liquid Roof. There is another brand that gets good reviews and they will come to your rig to apply!

Thanks!
