Our Flat Roofing Services in Manchester
New Flat Roof Installations
Building an extension, garage, or dormer? We install flat roofs from scratch using premium materials suited to Manchester’s demanding weather. Every new flat roof we install comes with a full workmanship guarantee and is built to last 20 years or more with the right system.
Flat Roof Repairs
Leaking flat roof? Cracks, blisters, ponding water, and splits are the most common flat roof problems we see across Manchester. We diagnose the issue quickly and carry out lasting repairs using matched materials. For older felt flat roofs nearing end-of-life, we will always give you an honest recommendation on whether a repair or full replacement makes better long-term sense.
For urgent leaks, see our 24/7 emergency roofing service.
Flat Roof Replacement
If your flat roof is beyond repair — typically after 15-20 years for felt systems — a full replacement is the most cost-effective option. We strip the old covering back to the deck, inspect for any timber damage, and install a new system that will protect your property for decades.
Flat Roofing Materials We Use
GRP Fibreglass Flat Roofing
GRP (Glass Reinforced Polyester) is the gold standard for modern flat roofing. It creates a single, seamless membrane with no joints or seams to fail. A properly installed GRP flat roof will last 30+ years with virtually no maintenance. It is ideal for extensions, porches, bay window roofs, and garages across Manchester.
Learn more about our specialist GRP fibreglass roofing service.
EPDM Rubber Flat Roofing
EPDM (Ethylene Propylene Diene Monomer) rubber is a highly durable single-sheet membrane system. It is flexible, UV-resistant, and can last 40+ years. EPDM is often the best choice for larger flat roofs and commercial applications where a single-piece covering is needed.
Felt Flat Roofing
Traditional felt remains a popular and affordable flat roofing option. Modern torch-on felt systems offer improved durability over the older pour-and-roll methods. Felt is a practical choice for budget-conscious projects, though it has a shorter lifespan (10-15 years) compared to GRP or EPDM.
