It's not cheap but in my opinion it was worth it. It's transferable so it should add to the value of your trade/sale later down the line along with the fact that you can pretty much prove that you have never had a leak. It is also cheaper than some of the other roof treatments that I researched. All in all mine cost about $3400. Check out the website and you can get a quote via email if it is something that you have or are thinking about.
