Ridge Caps

laying of ridge caps

Lay ridge caps from the opposite end of the roof to the direction of prevailing winds. Each cap should be overlapped by the next cap in the run by a minimum of 150mm.

We usually recommend ridge caps are fixed using self-drilling TEK type stitching screws to the high point of each profile they cover and through the appropriate ridge filler if one is being used. This helps ensure a robust weather resistant joint as well as keeping out birds and vermin.

Top tip - When constructing your purlin support structure consideration should be given to the need for additional purlins to support your ridge caps and other flashings.
