Flat Roof Installation in Bodmin & Cornwall
Flat roofs need to work harder in Bodmin & Cornwall's wet climate. At NL Roofing we install GRP fibreglass, EPDM rubber, and torch-on felt systems that are fully waterproofed and thermally efficient — built to last, not just to pass a visual inspection.
What's involved in a flat roof installation
Every flat roof job starts with a survey of the existing deck. We check for any soft spots, water damage, or failed insulation that needs to be addressed before any new material goes down. Getting this right first time is the difference between a flat roof that lasts and one that causes problems.
Once the deck is sound, we install the right system for your roof — either a fully seamless GRP fibreglass membrane or traditional lead, depending on the property and the detail required. Every installation is finished with properly formed lead flashings to all abutments and upstands, and we don't consider the job done until there are zero leak points.
Included as standard
- Full inspection of existing deck and substrate
- All waste stripped and removed from site
- New insulation board where required
- Seamless GRP membrane, fully bonded
- Lead flashings to all upstands and abutments
- 25-year manufacturer guarantee (GRP) + 15-year workmanship guarantee
Flat roof systems we install
We work with all the main flat roof systems and will recommend the best one for your property, budget, and roof shape.
GRP Fibreglass
Our most popular flat roof system. GRP is laid as a single seamless skin — no joints, no weak points. Incredibly durable, maintenance-free, and backed by a 25-year manufacturer's guarantee. Ideal for extensions, garages, and flat roof sections.
Lead Roofs
Lead is a time-served roofing material renowned for its longevity and weather resistance. We install lead on flat and low-pitched roofs, dormers, bay tops, and complex details where a durable, malleable material is essential. Correctly laid lead can last well over 100 years.
