Hello Roofing experts, I have recently bought an older house in the Washington DC area, which has a flat tin roof in bad condition. I have estimates from two different roofing companies, each of which propose a different solution. What are the pros and cons of each?
Company #1 suggests installing a 43 lb. fiberglass underlayment and then a new Firestone APP modified bitumen roof, one ply rubber roof using the torch down method. it carries a 12 year manufacturerÃƒâ€šÃ‚Â´s warranty on the rubber material and a 3-year warranty on labor. There is also the option of installing a densdeck insulation board and/or installing a 20-year rubber roof? (does that mean more coats or what?)
Company #2 proposes to install a Sealoflex 3-coat system brushed and rolled over the existing metal roof, consisting of a pink base coat with fiberglass mat and two finish coats. Final color = white, and there is a 10-year warranty on materials, five year on labor.
Thanks for your input. these things are difficult for the neophyte to compare.
