5 Signs your roof needs a repair.
When it comes to early signs of roof damage, homeowners often struggle to identify them and avoid major issues down the line. The majority of the time, issues are quick fixes you can handle yourself or hire a professional to handle.
We decided to make an article to help identify minor issues and prevent further damage:
1. Water stains and small leaks
In the UK, normally the first repair warning sign is water staining or small leaks, which can often be diagnosed as a cracked tile, damaged flashing, or a weak area in the protective covering.
If these damages are addressed early, they are often a quick, cheap fix, preventing more serious problems down the line.
2. Lose or slipped tiles
After periods of more extreme weather, such as storms or strong winds, tiles may become dislodged or come loose. Even one tile being moved out of position is enough to let water through.
Things to look out for:
Tiles have slipped out of alignment.
Cracked or broken slate.
Gaps in the roof surface.
If noticed early on, these problems are often localised and can be fixed without a full replacement.
3. Block and damaged gutters and valleys
If water starts pooling in gutters and / or roof valleys, it can break the protective layer and cause leaks, leading to further damage. moss, natural materials, and debris, and the common pollutants of water accumulating due to London's pollution and trees.
Clearing cutters and roofs of leaves and other debris is often all it takes to fix the problem. Luckily for you, as a roofer, this can be done in less than 1 hour.
4. Dampness or mold in the loft
A good rule of thumb is to check your loft a couple of days after a storm to make sure that there hasn't been any damage. Usually, this is where you can notice the first signs.
look out for:
Damp timber
Black mold
Dripping water
5. damaged flashing or worn seals
Flashing is the material around where your tiles meet bricks or chimneys. Over time, due to temperature changes, it can crack, which is one of the most common causes of roof leaks.
Luckily, it's a very quick fix when caught early, and the leaks haven't damaged any of the timber structure.
Why roof repairs are important in London
Due to London's constantly changing weather, all roofs are susceptible to damage, and catching these signs early can save you a lot of money. Most things here can be fixed in less than a day and won't cost you much.
