Ridge Caps

Ridge flashing installation is a task that should be carried out towards the end of your roofing project. If you have a sloped roof with two sides, which meet at an apex in the middle, you will need to know how to install roof cap ridges. Roofs without adequate ridge capping could be a costly error that you may end up paying for in years to come. Rain, snow and winds can seep through the gaps in the apex of the roof, and they’ll compromise your energy supply and allow heat to escape.


Ridge Flashing Installation

When constructing your purlin support structure, consideration should be given if the need for additional purlins is required. Be sure to purchase enough purlins to allow for this part of the project and don’t forget to install them before completing the ridge section.

How to Install Ridge Flashing

Begin by determining which end of your ridge is least affected by the wind. Your first ridge flashing should be laid at this point, and each flashing thereafter overlapped by the next flashing on the run by an absolute minimum of 150mm.

We recommend fixing your ridge flashings with a self-drilling TEK type stitching screw into the highest point of each profile they cover, ensuring they also penetrate any ridge filler being used. Foam fillers can be used for eaves and ridges if required to seal off ends or left out if you wish to keep the ventilation. Fillers can help ensure a robust weather resistant joint as well as keeping out birds and vermin.
