For Windham’s larger homes, Master Roofers recommends the GAF Timberline UHDZ or Camelot II shingle line paired with GAF WeatherBlocker premium underlayment, full ice-and-water shield in all valleys and eave edges, and a ridge vent system with baffled soffit vents. This system qualifies for GAF’s Golden Pledge warranty — the strongest roofing warranty available — which is transferable to future owners at the time of sale.
