A leaky roof is one of the most common problems homeowners face. This is a problem that never resolves itself. It may start with a small water drip from the ceiling after heavy rainfall, but over time, it can turn into damp walls, stained ceilings, and expensive structural damage. As one of the most trusted commercial roofing contractors Ealing and the surrounding areas, we at GTB Builders frequently have homeowners getting in touch with us only after damage has been extended. The good news is: if you notice the signs early and understand what to do, you can avoid worsening the situation.
What are the Causes of a Leaky Roof?
Here are the most common reasons for a leaking roof:
- Missing, slipped, or broken tiles (often after storms and wind)
- Damaged flashing around roof joins, chimneys, or abutments
- Broken or blocked gutters that could cause water to overflow into the roof edges
- Worn roofing felt/underlay (often due to gradual deterioration)
- Cracked seals around the roof vents, pipe peneteraions or skylights
Heavy or wind-driven rain for a long period of time can test these vulnerable areas. In the UK, heavy and repeated rainfall followed by drying can weaken seals and flashing, which is why a leak appears after many days of bad weather rather than during the first shower.
How Much Does It Cost to Repair a Roof Leak?
You might be wondering: How much does a small roof leak repair cost? Depending on the material, severity, and accessibility of the roof, the cost could range from £150 to £500 in the UK. Larger and more complicated roof leak repairs may cost more than minor repairs, which typically cost between £100 and £200. But keep in mind that this is an estimate, so you can’t rely solely on these figures to fix your leaky roof. You can speak to GTB Builders to find out the precise cost of fixing a roof leak.
What is the Best Way to Fix a Leaking Roof?
Here’s what you can do to fix a leaking roof:
- First, you need to look for signs of water damage, such as stains, wet spots, or mould.
- Place a container or bucket under a leaky roof.
- To puncture a small hole in the middle of the bulge, you can use a sharp object like a utility knife. This will help you drain trapped water into your bucket.
- Make sure to wipe down the wet surfaces with rags or towels. If possible, make sure to improve ventilation to help dry the area. To increase airflow, you can use fans or open windows.
- Clean and dry the area around the leaks.
- You can use a roofing tape to cover the leak. Create a seal by pressing it firmly into place. Additionally, you can also apply roofing caulk to the hole or crack.
- Make sure to use a plastic sheet to cover a leaky roof. You can use wooden boards to secure the edges of the plastic sheeting.
- Make sure the roofing tape is still there to seal leaks.
By opting for these practices, you can fix leaks temporarily. You can contact a roofing professional, like GTB Builders, for emergency roof leak repair and permanent fixes. We can also help inspect and repair the damage properly. If one area of your roof is leaking, there is a chance that other parts of the roof could also leak. A complete inspection can spot potential issues before they become major issues.
Can You Repair a Leaking Roof from the Inside?
Yes, you can temporarily repair a leaking roof from the inside, specifically to stop water drainage during heavy rain. This method is effective for emergencies, such as sealing small holes or cracks in roofing felt within a loft space using specialized patches or sealants. However, for a long-term solution, it’s highly suggested to have the roof inspected and repaired by professional roofers, such as GTB Builders.
Is It Normal for a Roof to Leak in Heavy Rain?
While it’s common for a roof to leak in heavy rain, it is not considered normal for a healthy roof to leak even in heavy rain. There are many reasons for a roof to leak in heavy rain, such as:
- Missing or damaged shingles
- Missing or damaged roof tiles
- Blocked guttering
- Built-up debris in roof valleys
- Damaged or poor-quality flashing
- Old roofing
- Poorly installed skylights
- Improper drainage on flat roofing
- Moisture build-up in lofts
- Incorrectly installed tiles and roofing sheets
- Pipe boot failures
