Although new construction roofing also involves installing roofing materials directly onto the roof itself, it's not quite the same as roof replacement. Roof replacement also includes tearing off the old roofing materials attached to the home, but there's no old roofing material to tear off in new construction roofing. It's carried out at the same time as other construction work. First, the roofers will build the framework, then the underlayment and the roof covering will be installed. Finally, they will install the shingles, and the new home will have a roof!
