Whilst I think that anything that Michael Morro says is as close to gospel as we can get, I am currently working on a foam roofing problem on a property that has a 13 year old roof. Again, that wonderful sunshine in California, eats away the sealers and the paint, and causes blistering on the foam, which quickly deteriorates if left untreated. Seemingly the sealent wears off, and has to be recoated every 2-3 years, which may be more hassle than you want. I do not know of any better solutions, yet, but I am working on finding some roofers to come and give me bids on replace versus repair. And it may be that this was a poorly executed job, and when done right, as Michael suggests, it will have a much longer lifespan.
