If roof is not leaking and just looks discolored (IE not white) just ignore the discoloration.Īlso, NEVER USE ANY PRODUCT THAT CONTAINS SILICONE!!! When roofing turns black that means it's life is over and having NEW roofing put on is the proper fix. If you do it WILL be a very short term 'fix' at best. There is a very good chance that Blackjack material contains petroleum distillates which WILL attack any synthetic and natural rubber along with vinyl and severally damage the existing roofing.Īs stated, unless the roof is showing BLACK you should never apply any other material over top. If the Blackjack manufacturer specifically states not to use, you really SHOULD HEED THAT WARNING!

TPO is a synthetic rubber like material which IS made from petroleum products. I am a newbie and just learning so what's the difference between a rubber roof and a TPO roof please. Money wise this would be great for me, but if you think I shouldn't use it can you please recommend the next best product that won't cost me a arm and a leg. Can anyone explain that to me? Like I said others have used it on rubber but others say do not use it. I am assuming I have the rubber roof but I do NOT know what a TPO roof is. I have read in other forums about other people using this but when I read the Precautions on the can it specifically says DO NOT use on TPO or rubber roofs. The roof needs some TLC and I was all set to purchase this product Blackjack 1000 ultra roof coating.
