The difference between a metal roof that lasts decades and one that develops problems within years often comes down to installation quality. In La Crosse, WI, where seasonal temperature swings exceed 100 degrees, proper installation becomes even more critical. At MQ Roofing, our metal roofers follow precision-based protocols that account for these unique regional challenges. Our specialists at (608) 553-3300 understand that durability begins long before the first panel is secured.
Correct Installation Steps
Material Acclimation: The Overlooked First Step
Professional metal roofers recognize that metal panels need time to adjust to local conditions before installation. This acclimation period, typically 24-48 hours, allows materials to reach equilibrium with the surrounding environment. Skipping this step often leads to improper tensioning as panels expand or contract after installation. Our teams schedule deliveries specifically to allow this crucial adjustment period, particularly during temperature extremes.
Precision Underlayment Creates the Foundation
What happens beneath metal panels largely determines a roof’s lifespan. Quality installers use synthetic underlayment with proper overlaps (minimum 6 inches at horizontal seams, 12 inches at vertical transitions). The underlayment must be properly tensioned – not too tight to allow for structural movement, yet not so loose it creates waves. This invisible layer becomes your roof’s critical second line of defense against moisture intrusion.
Fastener Selection and Placement
The science of fastening goes far beyond simply securing panels. Professional metal roofers select fasteners based on metal compatibility to prevent galvanic corrosion. Proper torque settings ensure fasteners are tight enough to create weatherproof seals without over-compressing washers or denting panels. Equally important is fastener placement – following engineer-specified patterns that account for wind uplift pressures at different roof zones.
Allowance for Thermal Movement
Metal expands and contracts with temperature changes. Expert metal roofers calculate specific expansion gaps based on panel length, material type, and local climate data. These precise measurements prevent buckling, oil-canning, and fastener stress that can compromise roof integrity. Proper installation includes specialized clips and fastening systems that allow this natural movement while maintaining weather resistance.
Flashing Details Make or Break Performance
The most vulnerable areas of any metal roof are its transitions and terminations. Professional installers create custom flashing components for each unique roof intersection rather than using one-size-fits-all solutions. These hand-fabricated pieces follow specific design principles for proper water channeling, including adequate overlaps, hemmed edges for strength, and appropriate sealant placement only where absolutely necessary.
