Minnesota Roofing Contractors are busy these days. Much like road construction’s heavy load in the summer, the Minnesota Roofing industry is buzzing as well. When Minnesota homeowners consider roof replacement, there are several critical things to know before the process begins.
Improper nail installation techniques will void the shingle manufacturer’s warranty. Don’t trust just any Minnesota Roofing Contractor.
Too few nails installed per shingle, deferred nail gun maintenance, inadequate nail gun air pressure, and nails not secured in the correct location on the shingle are common errors we find when called upon to repair improperly installed shingles. Too few nails per shingle affects wind rating and wind tolerance. Inadequate nail gun maintenance affects the consistency and performance of nailing patters, and commonly leaves nails installed not flush into the wood underlayment causing rubbing and marring of the shingle underside. Inadequate nail gun pressure leaves nails loose and promotes severe nail popping. Nails driven into the asphalt sealing strip will prevent shingles from bonding and sealing over time as required. These conditions are common precursors to significant damage not covered under insurance policies or manufacturers warranties. This is why a dependable craftsmanship warranty is extremely important.
