Most roofing deteriorates over time, especially those at the highest points of a property where harsh weather conditions take their toll on materials, such as clay tiles. Whether it’s roof repairs for a listed building or maintenance work on a pitched roof, repointing ridge tiles is a task regularly undertaken by roofers across the UK.
Here’s everything you need to know about repointing roof ridge tiles.
What are roof ridge tiles?
Roof ridge tiles run along a pitched roof at the intersection where the sides meet, playing a vital role in the structural integrity of your roofing. They also ensure your roof stays as watertight as possible, as the point where two surfaces join is often the place where water tends to creep in.
Most ridge tiles are manufactured from clay or slate, but you may also find some made from concrete on larger roofs. They come in various shapes and sizes, remaining in keeping with the rest of the roof.
How are roof tiles damaged?
Ridge tiles can become damaged through general wear and tear, but it’s often extreme weather conditions such as heavy rainfall, strong winds and storms that cause deterioration.
If the mortar between roof tiles becomes broken or loose, it can be scraped away and replaced as new, ensuring roofing remains as stable as possible.
How to repoint ridge tiles
Once the area is secure, the first job is to remove the affected tiles, levering them away from the roof as carefully as possible. Your roofer may want to inspect the area underneath for damage and may have previously recommended buying replacement ridge tiles if there’s extensive damage.
Once the roof is prepared for repointing, the new tiles are secured in place by appropriate means, including clamps, nails and replacing the mortar. The recommended method is via mechanical fixing, which can take a little more time but is worth it for the long-lasting results achieved.
Top roof safety tips
The main issue with roof safety when it comes to repointing ridge tiles is the heights involved. This means roofers will need to ensure they can work safely without causing further damage to your property, finding ways to carefully remove unwanted debris and materials from the area.
Professional roofers will have the right safety equipment (including scaffolding) to stay safe on your roof, keeping the structure stable during the job. They’ll also understand how to prevent further damage to other tiles in place across the roof while maintaining the ridges as the repointing work is carried out.
