At Fortress Roofing, we provide professional flat roofing services for homeowners across Thornbury and the surrounding areas. Whether you need a new flat roof for an extension, repairs to an existing system, or a complete flat roof replacement, our experienced team can provide a practical, long-lasting solution.

Flat roofs are commonly used on home extensions, garages, porches, outbuildings, and some residential properties. When installed correctly, they offer excellent protection, a neat appearance, and a cost-effective solution where a pitched roof may not be suitable.

However, flat roofing needs the right materials, proper drainage, and careful installation to perform well. Poor workmanship can lead to leaks, standing water, cracks, and premature failure. At Fortress Roofing, we focus on quality from the start, ensuring your flat roof is durable, weatherproof, and suited to your property.

New Flat Roof Installations

If you are building an extension, garage, porch, or outbuilding, a flat roof can be a practical and cost-effective option. We install flat roofing systems designed to provide strong waterproof protection and a neat finish.

Before installation begins, we consider the structure, drainage, insulation, and best material for the project. This helps ensure your new flat roof performs properly and remains reliable for years to come.

A well-installed flat roof can be low-maintenance, weather-resistant, and suitable for a wide range of residential applications.

Flat Roof Replacements

If your existing flat roof is repeatedly leaking, badly worn, or reaching the end of its lifespan, replacement may be the best option. We provide full flat roof replacement services, removing the old system and installing a new, durable roof.

During the replacement process, we also inspect the structure beneath the roof covering. This is important because hidden damage, trapped moisture, or timber deterioration can affect the performance of the new system if not dealt with properly.

Our aim is to provide a replacement flat roof that improves protection, appearance, and long-term reliability.

Emergency Flat Roof Repairs

Flat roof leaks can cause internal damage quickly, especially during heavy rain. If your flat roof has suddenly failed or started leaking, we can provide emergency roofing support to help protect your home.

Where a full repair cannot be completed immediately, we may be able to provide temporary protection before returning to carry out a permanent solution.

If you need urgent help, call 07988 084870.

Liquid Roofing Systems

Liquid-applied roofing creates a seamless waterproof coating and can be useful for certain repair or refurbishment projects. It can often be applied around awkward details and roof features.

We will explain the benefits of each option and recommend the most suitable system for your property.

Why Quality Installation Matters

Flat roofing relies heavily on correct installation. Even high-quality materials can fail early if the roof is not fitted properly.

Important details include:

  • Correct roof fall and drainage
  • Proper sealing around edges and joints
  • Suitable ventilation where required
  • Strong waterproofing around roof details
  • Careful preparation of the roof structure
  • Quality finishing around outlets and upstands

At Fortress Roofing, we pay close attention to these details to reduce the risk of leaks, standing water, and premature wear.
