Emergency Roof Leak Repair in Slough & Windsor

For most homes, replacing a roof falls under permitted development, provided the materials are similar in appearance to the original. However, if you live in a conservation area in Windsor, Datchet, or Maidenhead, or if your building is listed, strict Article 4 directions may apply. This often means you must use specific materials like natural slate or clay peg tiles. We can advise you on what is required to stay compliant with the Royal Borough of Windsor and Maidenhead or Slough Borough Council regulations.

Under Building Regulations Part L, if you replace more than 50% of your roof covering, you are usually required to upgrade the thermal insulation to meet current U-values. This is an excellent time to improve your home’s energy efficiency. We can install modern breathable membranes and high-quality insulation as part of the re-roofing process to help lower your heating bills.

EPDM is a synthetic rubber membrane that is laid in large, single sheets, meaning there are no joints for water to get through. It is very flexible and handles temperature changes well. GRP fibreglass is a cold-applied liquid resin that cures into a hard, impact-resistant surface. GRP is often preferred for balconies or areas with light foot traffic because of its toughness, while EPDM is a cost-effective, long-life solution for standard extensions and garages.

Chimneys are highly exposed to the elements. Years of freeze-thaw cycles, where moisture enters the mortar and expands as it freezes, causes the material to crack. Additionally, acidic gases from older heating systems can degrade the brickwork from the inside out. We provide structural repointing and can replace perished bricks to stabilise the stack and stop leaks around the lead flashing.

Yes. The valley is the internal angle where two roof slopes meet, often lined with lead. If the lead has thinned or cracked, it will cause a significant leak. We can carefully remove the surrounding tiles or slates, install a new Code 4 or Code 5 lead valley or a modern GRP liner, and then reinstate the tiles. This is a common and effective way to stop a leak without the cost of a full replacement.

In many older homes across Slough and Maidenhead, ridge tiles are held in place only by mortar. As the house settles and the mortar ages, the bond weakens. High wind speeds create uplift, which can pop these loose tiles off the roof. When we perform ridge tile re-bedding, we ensure a deep mortar bed or recommend a mechanical dry-fix system which screws the tiles into the timber structure for maximum security.
