Flat Roofing Repairs & Replacement Lewes

If your flat roof is showing signs of damage, the right solution will depend on the overall condition of the roof. In many cases, a targeted repair can resolve isolated problems and extend the life of the existing roof.

Problems we solve

Leaking roofs demand immediate attention

Flat roofing problems rarely fix themselves. What may start as a small issue can quickly develop into a more serious and expensive repair if left unresolved. Our team helps property owners in Lewes identify problems early and choose the most practical solution before further damage occurs.

Common flat roofing problems we deal with include:

Leaking flat roofs causing damp patches, water ingress, and internal staining
Blistering, cracking, or lifting membranes that allow water to penetrate the roof surface
Pooling water caused by poor drainage or ageing roofing materials
Cold rooms and heat loss from older flat roof construction and worn insulation
Loose ridge, hip, or verge areas that allow wind-driven rain to enter the property
Recurring mortar failures on ridge or verge lines that repeatedly require repair

Types of flat roofing we can install

Torch on felt roofing

A proven, cost-effective system for many flat and low-pitch roofs. Installed in layered sections and heat-bonded to create a watertight seal.

GRP fibreglass

A modern, joint-free system installed over solid decking with resin, matting, and topcoat. Known for a clean finish, low maintenance, and long lifespan.

Polycarbonate roofs

A lightweight and durable option for canopies, patio covers, conservatories, and walkways, allowing natural light while staying weather-resistant.

Warm roof construction

Insulation is fitted above the roof structure and below the weatherproof layer, helping reduce heat loss and lowering condensation risk.

What our customers say

"Liam did a great job resurfacing the flat roof on our house. Even with inclement weather the job was finished in good time! The quote was very reasonable and Liam listened to what we needed and also to what was in our budget. Liam was very helpful, polite and tidy."

"Liam and team did a fantastic job of replacing our roof and refelting another flat area. Everything was done on time and to a high standard for a reasonable price. We were very happy with it service we received. There was a lot of mess while they were working but they left everything very clean and tidy once they finished."

"Liam and Reece stripped and relaid a flat roof over the hallway in a day, making sure all defects were repaired, and kept me informed about progress, providing before and after photos. They were professional and courteous, and cleared up all the resulting debris until nothing remained. A good job at a reasonable cost."

Frequently asked questions

Find answers to common questions about our flat roofing services.

How long should a flat roof last?

The lifespan of a flat roof depends on the system used and the quality of the installation. Many modern flat roofing systems can last for many years when installed correctly and maintained properly. Properties across Lewes and the surrounding East Sussex area, including villages such as Ringmer, Plumpton, and Newick, commonly use flat roofing for extensions, garages, and dormers. Lewes sits in the Ouse Valley and is exposed to strong prevailing winds coming off the South Downs, which can accelerate wear on roofing membranes and make quality installation particularly important.

Is torch-on felt or GRP better?

Both systems have their advantages. Torch-on felt is a traditional flat roofing solution known for its strength and layered waterproof protection. GRP (fibreglass) roofing creates a seamless finish that is highly resistant to leaks. The right option often depends on the size of the roof, the existing structure, and the specific property.

What is a warm roof and do I need one?

A warm roof is a type of flat roof construction where insulation is placed above the roof deck rather than below it. This helps reduce heat loss and prevents condensation issues. Warm roofs are commonly recommended for new flat roof installations and replacements, particularly on extensions and renovated properties in Lewes and across the East Sussex district.

Can you repair a flat roof instead of replacing it?

Yes, many flat roofs can be repaired if the damage is limited to specific areas and the overall structure is still sound. Small leaks, membrane damage, or isolated faults can often be fixed without needing a full replacement. If the roofing system is failing across multiple sections, however, replacement may be the better long-term solution.

Do you work on garages, dormers, and balconies?

Yes, flat roofing is commonly used on garages, dormers, balconies, and home extensions. We regularly carry out work on these types of roofs across Lewes and nearby areas such as Ringmer, Ditchling, and Barcombe.

Can I submit a question before booking?

Absolutely. If you have a question about a flat roof problem or want advice before arranging an inspection, you can get in touch and we’ll be happy to help. Whether you’re based in central Lewes or surrounding villages such as Glynde or Rodmell, we’re always happy to provide guidance.
