"Thanks to advances in metal roofing technology, metal roofing in Maine has become an increasingly popular material. These roofs can withstand winds of up to 120mph, and are also now more than ever more resistant to rust. And since they are reinforced with layers of inner sheets and coatings, homeowners expect a low-maintenance roofing system that last them 50 years or longer. For Maine's residents, dealing with seasonal storms is part of the lifestyle peril of living in “Vacationland.” Getting a metal roof in Maine resolves much of that worry while the material has come to represent elegance and dependability even in the harshest of weathers."
