Rubber Roofs

My rubber roof is also 15 years old and fine. Big problem with roofs (All kinds) is the seams. Any cracks or bad looking areas should be looked after. I use Dicor lap sealant. Others like other products but the dicor stays some what soft and can be removed with a plastic putty knife if a small area needs replacing. And a small area will blend in with the old seam. Remember the roof is a large flat area that is working and twisting all the time so keep an eye on all the seams.. In all truth I think and rubber roofs are the best after spending a couple weeks helping a friend replace much of his fiber glass roof. There is no real fix it once and forget it product no matter what others say. I am not saying Dicor is the best just the easiest to work with over the years..
