Many companies have multiple brackets or clamps with different installation techniques.) 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. Still, SnapNrack suggests installers use a compatible adhesive sealant to ensure a waterproof connection. The fastener is positioned at the top of the ridge, out of the water channel. SnapNrack’s Corrugated Straddle Block attaches to the roof at the peak of the corrugation. The type of metal roof will affect the type of solar mounting system needed for a successful install.Įach mounting manufacturer has a different design and way to attach to sinusoidal corrugated roofs. Trapezoidal roofing has more flat space in between peaks. For example, sinusoidal corrugated roofing’s ridges and grooves are closer together, in a consistent wave-like pattern. To further complicate things, there are several variations of metal roofs. SnapNrack’s Corrugated Straddle Block can be used on sinusoidal corrugated and trapezoidal metal roofs
