Leaking Flat Roof Repair for Extension in Wirral
We have a flat roof (9 x 6 feet) that is leaking water into the premises. The roof is located on an extension and is covered with roofing felt. We need a repair to stop further water damage.
Common Causes of Flat Roof Leaks
Flat roofs, especially those covered in roofing felt, are susceptible to wear and tear over time. Some common causes of leaks include:
- Cracked or Blistered Felt: Over time, felt roofing can develop cracks or bubbles that allow water to seep through.
- Poor Drainage: Standing water on a flat roof can weaken the surface and lead to leaks.
- Loose or Damaged Flashing: Flashing around the edges of the roof may deteriorate, allowing water ingress.
- Seam Failures: Weak points where felt sheets are joined may separate, creating leak points.
Steps to Repair a Leaking Felt Flat Roof
The repair process depends on the severity of the damage but typically involves:
1. Inspection and Leak Detection
- Identifying the exact source of the leak.
- Checking for additional signs of damage, such as sagging or pooling water.
2. Patching Small Leaks
- Cleaning the damaged area and removing loose debris.
- Applying a specialist roofing felt adhesive or liquid waterproofing membrane.
- Sealing the area with an extra layer of felt or a patch repair.
3. Resealing Flashing and Joints
- Inspecting and replacing any damaged flashing.
- Sealing edges with a weatherproof sealant.
4. Full Felt Roof Overlay (If Necessary)
- If the damage is widespread, a full overlay with new felt may be required.
- Installing high-performance torch-on felt for enhanced durability.
