Now, let's talk about the second part of your question, because understanding what causes roof leaks in the first place is very helpful for any homeowner. Knowing the common reasons for leaks can help you spot the signs early and call us before a small issue turns into a very big, expensive repair. In Glasgow, most roof leaks are caused by a mix of old age, harsh weather, and simple wear and tear.
One of the most frequent causes of leaks is missing, broken, or cracked tiles and slates. This is very common, especially after a strong storm or a windy night. Roof tiles and slates are the first line of defence against the rain. When they break, the protective barrier is gone, and water flows straight onto the wooden roof structure underneath, leading to a leak inside your home. The tiles can break for many reasons: strong winds lifting them, someone walking incorrectly on the roof, or simply the material getting old and brittle over time. If you see pieces of tile or slate on the ground around your house after bad weather, it is a sure sign you need our repair services right away.
Another major culprit in roof leaks, particularly in Glasgow where many homes have chimneys, is faulty or deteriorated lead flashing. Flashing is thin strips of metal, most often lead, that are used to create a watertight seal where the roof meets a vertical surface, such as a chimney stack, a wall, or in the valleys where two sections of the roof join together. Lead is a fantastic material, but it can age, crack, or become loose over time. When the flashing fails, it creates a direct path for water to enter the building. Sometimes, the lead is stolen—a terrible problem that leads to huge leaks very quickly. Other times, the cement or mortar holding the lead in place cracks and allows water in. Repairing or replacing lead flashing is one of the most common and important jobs we do at Glasgow Roofmasters.
The presence of moss and vegetation is also a surprisingly common cause of leaks. Over time, moss, lichen, and even small plants can take root on your roof tiles. Moss acts like a sponge, holding onto water. This means your roof is constantly damp. In winter, that water freezes, expands, and pushes the tiles apart or cracks them. The moss itself can also stop water from flowing correctly down the roof and into the gutters, forcing it sideways and under the tiles, where it can cause a leak. While some moss looks natural, heavy build-up is a clear sign that your roof needs professional cleaning and repair to prevent future leaks.
Leaks are also frequently caused by problems with the gutters, fascias, and soffits. While these are not technically part of the roof surface, they are part of the overall roofing system. If your gutters are clogged with leaves and debris, they cannot carry rainwater away from the house. When the water backs up, it often overflows and soaks the wooden fascias and soffits, or even runs back up underneath the tiles, leading to leaks and rot. We always check and clean the gutters as part of a thorough repair job because we know they are vital for keeping your roof leak-free.
Finally, and especially in older Glasgow homes, leaks can be caused by the simple age and wear of the roofing felt or the underlay beneath the tiles. This felt is a backup layer of protection. Over many, many years, this material can become brittle, tear, or even just crumble away. If the felt fails, and a small amount of water gets past the tiles—which happens even on a good roof—there is nothing to stop that water from getting into the roof space and causing a leak. In these cases, we often have to lift a section of tiles, replace the felt, and then carefully put the original tiles back, giving your roof a fresh, new layer of protection underneath.
