You asked us to send you a note on our feedback. As a roofer we have tried many products Sealoflex, Santi-Tred, Snow Roof and everything in between. Yours is what we will be using from now on. We are especially impressed with the flexibility of your product. With the seasonal changes we find this is the major cause for cracking to occur with the other products we have used. I guess it goes without saying….You get what you pay for.
