The Green Sense Methodology
The expansion and contraction of the substrate, whether it be concrete or metal, causes either cracks in the concrete or openings in the endlaps and side laps on metal roofs and joints in most types of gutters. We take out the movement by installing an expandable ridge cap which acts as an expansion joint in the middle of the roof.
And in larger roofs where we need to take the movement out even further we install floating sheets, which like the expandable ridge cap prevents the movement forming on the endlaps.
Trust us when we say that if these techniques are not used, the end laps
