Built up Roofing (BUR) or traditional built up 3 layer flat roofing systems.

These roofs consist of multiple layers of roofing felt or fiberglass matting saturated with bitumen (asphalt). These layers are alternated with hot-applied bitumen or cold-applied adhesive. Gravel or a mineral surface is often applied to protect the roof from UV radiation and provide durability. BUR roofs are durable and long-lasting but can be heavy and require regular maintenance.

Single-Ply Membrane Flat Roofing

Single-ply roofing systems use a single layer of synthetic material, typically TPO, PVC, or EPDM. They are lightweight, easy to install, and offer good UV resistance. Single-ply membranes are versatile and have a relatively long lifespan.

EPDM Rubber Flat Roofing

EPDM is a type of single-ply membrane made of a rubber-like material. EPDM roofs are durable, flexible, and resistant to UV rays and weathering. They are often installed as large sheets, minimizing seams and potential leaks.

Fibreglass Roofing (GRP) Flat Roofing

GRP roofing involves a seamless, reinforced fiberglass mat that is saturated with a polyester resin. The layers are built up on the roof, creating a strong, watertight, and durable surface. Fibreglass roofs are lightweight, resistant to UV radiation, and have a long lifespan. They are known for their excellent waterproofing properties, low maintenance requirements and can be used in various applications, including flat roofs, balconies, and gutters. They are often used in residential and commercial settings, offering a smooth and aesthetically pleasing finish.

Green Flat Roofing

Green roofs also known as living roofs or eco-roofs, are vegetated layers installed on top of a building’s roof. They consist of a waterproofing layer, a root barrier, a drainage system, a growing medium (soil or substrate), and various types of plants or vegetation.

Our Flat Roofing Project Gallery


Replaced the entire roof on our house.

Having used Ben on smaller jobs in the past we were very confident he was the man to take on the much larger job of sympathetically replacing our roof in keeping with the age of our house (several centuries old). Despite many tricky sections where different elevations met, plus two flat roofs, dormer windows and a balcony to contend with, Ben and his team did a brilliant job. Ben’s communication was great right from very early planning/quoting stages right through to the end. He and all his guys were very reliable, polite and dependable. We are extremely happy with the end result.

Graham & Rowan Turrell

Replacing a section of the roof.

Reliable, great quality, very professional team. Ben came out to assess the problem, explained what was required, sent quote, dropped off sample tile as promised, and then his team completed the work on time and without fuss. Kept us informed throughout the job, showing us the damage and explaining exactly what was required. We were very impressed with every aspect of the work, everything left tidy afterwards too. Thank you Ben, Dave and the team. We wouldn’t hesitate to recommend these guys.

Adam Gibbons

Replace 25 year old felt on flat roof house extension.

Upgraded to a modern rubber roof system with purpose designed edging and trims; ventilation was incorporated on Ben and Dave’s advice. The finished job looks terrific, and so much better than before. Work was done efficiently, care was taken with the house’s wall coating, and all rubbish was cleared off site. All the workers were a pleasure to have around. Would definitely recommend BJ Roofing.

Patt Jeffcoate

Removal and reinstallation of extension roof

Extremely professional from first contact quote through to completion of the job. The team on site were thoughtful and polite and kept me updated on the progress of the work. Would not hesitate to recommend.

Zoe Green

Tiled a complicated extension and 2 front porches

Exceptional! I’ve used roofers before on building projects, but Benjamin James is by far the best. All the staff were customer-friendly and the quality of the workmanship and tidiness was exceptional. They gave me peace of mind so I could leave them to it without worry. One of the best trades I’ve come across. An absolute pleasure to deal with from start to finish. Professional, competitively priced and really polite. Would absolutely recommend.
