Flat Roofing
At CGL we also specialise in flat roofs and are forever installing new flat roofs. We only use the best materials to give you a longer-lasting flat roof. Our operatives are trained to the highest of standards and we pride ourselves on doing a good, neat job that the client is satisfied with.
We have qualified installers of the following membranes Sarnafil, FLAG and firestone. We have achieved great success in installing single-ply membrane roofs and can cover a 1m x 1m outhouse or 5,000 square metre flat roof.
With more flat roofs being built due to big open living extensions you need to make sure you have the correct material for the project.
We offer almost every possibility and system you could choose for a modern-day flat roof so we can point you in the right way of choosing what you want out of your roof and what material would be best for the size of the roof and project!
Reasons to go for a single-ply membrane roofs are:
- The material goes down quicker than felt, perfect for a job on a time limit.
- Comes with longer guarantees than felt
- Is designed to hold water and will not get broken down by UV rays making an ideal choice for a long-term choice for your flat roof.
- Gives a clean modern finish and can come in a colour of your choice (including copper effect and silver)
- Single-ply membrane comes with a 15-year guarantee or there Is an optional 20-year guarantee. We can offer budget membranes with 15-year guarantee also. For flat roofs, I wouldn’t recommend anything else other than single-ply membrane or felt as we are always replacing old roofs which have either been recently coated or had the grp fibreglass installed.

Our Services
General Roof Maintenance
Gutters start to rust and corrode if left untreated. CGL’s high quality gutter lining prevents rust, corrosion and other wear and tear. We have come across all shapes, sizes and profiles and have great success in lining with our seamless polypropylene gutterflex membrane into existing gutters.
GRP Fibreglass
GRP is comprised of polyester resin and chopped strand mat glass fibres, which are mixed together to form a laminate. GRP fibreglass has become one of the most popular forms of flat roofing systems because it is not only a strong material but doesn’t add too much extra weight to the structure.
