Technology has advanced to the point where modern metal finishes not only offer aesthetic value, but they also protect the roof panels from moisture and pollution.
I was raised on the construction adage: “More guys fall off of shallow pitches than steep ones,” and it has certainly proven true in my 35 years of construction history.
Successful metal roofing systems require proper attachment procedures, provisions for expansion and contraction, and expedient removal of water (snow and ice) from the roof surface.
The elements required for establishing proper roof maintenance guidelines on metal roof systems are similar to maintenance conducted on conventional systems.
The correct amount of replacement together with the initiation of a complete maintenance system can completely return the roof to original performance standards.
