I contacted this company because I noticed my roof was leaking. They came out immediately and put a tarp on my roof to prevent any further leaking. They advised me of what kind of damage they found on my roof. My insurance came out and confirmed this damage and paid for my roof to be completely replaced. Guardian Roof Systems put CertainTeed's top of the line roof system on with no additional cost to me other than my deductible from my insurance. I would recommend this company to anyone that is planning on replacing their roof or thinks that they may have damage on their roof.
