Whether or not you put weep holes on your tiled roof is a topic of much debate within the roofing community.

A weep hole is a nail sized hole in the top ridge pointing of a tiled roof. The holes are made every 30cm, along the ridge pointing and allow for water to escape. It is crucial that water can escape from the ridge pointing as the bedding holding this part of the roof together is cement. Cement, although strong, is porous which can allow for water to soak in and build up, resulting in cracking and other issues.

When flexible pointing was introduced people assumed that weep holes were now redundant, however this theory relies on the fact that the flexible pointing will uphold its integrity ‘til the end of time. This is why flexible pointing manufacturers recommend that you still use weep holes, and we agree, we will put weep holes in all our tile roofing.
