Flat Roof Installation

We install flat roofing systems designed to cope with UK weather and everyday use without early breakdown.

Flat Roof Replacement

If a flat roof has ongoing leaks, widespread cracking, sagging or repeated patch repairs, replacement is often the safest long-term option. We strip back failing materials, inspect the structure underneath, and replace the roof with a system suited to the building and how the roof is used.

Flat Roof Repairs

Flat roof leaks are commonly caused by split membranes, failed seams, damaged flashing or blocked outlets that lead to standing water. Our repair work focuses on finding where water is actually getting in and fixing the cause, not just the visible damage.

Flat Roof Inspections

A flat roof inspection is the best way to decide whether a repair or replacement is needed. We check the roof surface, seams, edges, outlets and vulnerable details, then explain the findings clearly so you know exactly what needs doing and why.

Emergency Flat Roof Repairs

When water is entering the property, speed matters. Emergency flat roof repairs are focused on making the roof watertight and preventing further damage, followed by clear advice on any permanent work needed to stop the issue returning.

About Our Flat Roofing Work in Buckingham

In Buckingham, we regularly work on flat roofs fitted to older garages, home extensions and dormers where original felt systems are now reaching the end of their lifespan. We also see problems caused by poor drainage, leading to ponding after rainfall, and weak edge detailing that allows water to track underneath the roof covering. Flat roofs in Buckingham often fail early when these details are rushed or ignored. Our work focuses on correcting those weak points so the roof performs properly long term.

Flat Roofing Systems We Work With

The right flat roofing system depends on the roof’s size, access, exposure and how it’s used. We work with a range of flat roofing materials and explain which options suit your property best after inspecting the roof.

EPDM Rubber Roofing

EPDM rubber roofing is a popular choice for residential flat roofs in Buckingham due to its flexibility and resistance to cracking. When installed correctly with secure edge detailing, it provides reliable waterproofing and handles movement well over time.

GRP Fibreglass Roofing

GRP fibreglass roofing creates a seamless, hard-wearing surface that suits smaller flat roofs and areas where a tougher finish is needed. Applied correctly, it forms a strong waterproof layer with clean detailing around edges and outlets.

Torch-On Felt Roofing

Modern torch-on felt systems remain a practical option when layered and finished properly. The lifespan of felt roofing depends heavily on preparation, detailing and drainage, which is where many older flat roofs fall short.

Liquid Roofing Systems

Liquid roofing systems can be suitable for flat roofs with complex shapes or detailing. They form a seamless waterproof coating and can be effective when installed under the right conditions with proper preparation.

We inspect the roof properly, explain the problem in plain language, and recommend work based on what the roof actually needs. Our focus is on drainage, edges and detailing, the areas that prevent repeat leaks and unnecessary future costs.

Removal of Chimney stack, replacement of roof underlay, guttering and flat roof repair. - Mitchell from Alliance Roofing & Building was the only builder, of many that I had contacted, that climbed a ladder to inspect my flat-roof and to climb into my loft-space to inspect the main roof from the inside. After an extensive review of my property and discussing my options, he emailed me his quotation on the same day. Booking in dates for Alliance & Roofing to commence work was quick and effortless. They arrived on time, completed the work as planned to a professional standard. Provided Photos of work carried out at all stages. I highly recommend Alliance Roofing & Building.
