I had a 16 year old architectural asphalt shingle roof that was just at that age it was needing some renovation even though I had installed 25 year Owens Corning shingles , this Georgia weather is tough on a roof. I contacted Matt at Guaranteed Roofing and he did an inspection, after I saw the pictures I decided to get the full treatment. It gave me a new roof and saved me thousands. I would recommend it 100% vs a new roof.
