The type of metal roof will affect the type of solar installation system required for a successful installation.
Each installation manufacturer has a different design and method to connect to a sinusoidal corrugated roof.
SnapNrack’s Corrugated Straddle Block attaches to the roof at the peak of the corrugation. The fastener is positioned at the top of the ridge, out of the water channel. Still, SnapNrack suggests installers use a compatible adhesive sealant to ensure a waterproof connection.
S-5!'s CorruBracket and EcoFasten's CorruSlide also span one ridge, but the CorruBracket attaches in the valleys, while the CorruSlide attaches more toward the bottom of the hump, not quite in the valley. (These are just a few examples. Many companies have multiple brackets or clamps with different installation techniques.)
