Has anyone used the RV roof magic product on their roof. According to manufacturer no primer is needed for application. If so how well does it hold up?

I am probley in the minority but I do not like or use total roof coatings. I reseal seams but why do the whole roof? I have seen roof coatings go bad making it tough to find the point of enrry.

I am probably somewhere in the middle. If your roof is okay, don't coat it. If it's getting older it may need coated.

I have found that by coating the roof, I don't get nearly as many black streaks on the side of fhe RV.

I'm not familiar with RV Roof Magic. I have used Heng's Rubber Roof Coating. It does not need a primer, goes on easily and holds up well to the Pennsylvania summers and icy, snowy winters.

I like "Henry Tropi-Cool" I ordered it through Home Depot. It applies really nice. NO primer, wash roof before application. If your roof is wearing down showing lots of Black Spots, it is time for a roof coating. My original roof was
26 years old. I used a 1/2" nap roller and one coat did the trick.

Can't go wrong with Henry roof coating. It is easy to apply, relatively inexpensive and 100% waterproof.

Just be careful using these roof coatings. Henry's makes two types, Silicone and Acrylic. The acrylic roof coating works best on standard membrane RV roofs like EPDM or TPO. The silicone is best for fiberglass, metal or bare wood roofs. Sadly the more expensive silicone won't last as long as the less expensive acrylic when applied to rubber roofs. This is the main reason so many complain that silicone roofs fail. It's not that the silicone roof is bad, just the wrong product was used. Likewise, the less expensive acrylic roof coating won't last as long as the silicone when dealing with hard roof surfaces like metal, fiberglass or even bare wood.

So, if you have a membrane roof, save the money and buy the less expensive acrylic as the silicone won't hold up much longer than the acrylic on those roof. If you have a hard roof, metal, fiberglass, wood, etc., definitely go with the silicone.
