I saw this post when I was googling RoofMaxx because I wanted to see what other peoples experiences were with it. I recently had it applied to my 1550 square foot home. So here is what I think, and why I bought it. I was cleaning my gutters and I noticed that my shingles were extremely brittle...My roof is over 23 years old so I figured it might be time to replace it. I have no leaks, and the home is in great condition. My neighbor, suggested that I could put it off for a few years with roofmaxx. Basically, the stuff hydrates the singles with a chemically altered oil that acts like penetrating oil. True to its word, my shingles are super flexible and they aren't crumbling like they were when I initially jiggled a few around. I would not recommend this product if your underlayment has been compromised and your roof is already leaking, but if you're trying to keep your shingles from sheering I think its the real deal. I read someone on this thread paid WAY more than I did. I think that anyone doing roofmax is just a general contractor selling the product like a franchise does, so you can definitely get price gauged like with any other product. I'll just say that what I paid was like 17 % of the cost of reroofing. It's been 8 months, shingles are still super flexi.
