Many historic homes in Gladwyne, PA featured low sloping or flat roofs that currently have rolled roofing or rubber roofing. Unfortunately, these roofs are only designed to last 10 years! That is why this homeowner chose a 50 Year Standing Seam Metal Roof for their low sloping roof. Becuase we use a mechanically seamed panel we are able to install our panels on roofs with a 1/12 pitch! Conversely, asphalt roofs are not warrantied below a 3/12 pitch, making metal roofing from Global the idea choice for any home with a low-pitched roof.
