Flat Roofing
A long-term solution

A long-term solution

Most conventional flat roofs are too cold in the winter and too warm in the summer. With Global Flat Roofs we have built in a warm deck insulation system as standard on all habitable rooms which means your room is warmer in the winter and cooler in the summer, while saving you thousands of Euro on heating bills. And with over four decades serving our customers, our team offers a friendly, stress-free service from your very first point of contact with us right through your 15-year guarantee and beyond.

Global Flat Roof design
Designed to protect the most vulnerable area of your home. Permanently.

We only use the highest quality materials to produce a monolithic laminated membrane that offers excellent weatherproofing.

Avoid costly roof repairs

Our harsh climate can cause blistering, cracking and leakage to occur. Chippings and moss are unsightly and require regular maintenance to keep the roof weatherproof. The cost of a replacement with a normal life expectancy for traditional materials is just 10-12 years. Get rid of one more worry - addressing your flat roof challenge can save you costly structural repairs, damp and redecorating bills.

Transform your home's energy efficiency
Reduce your carbon footprint & your heating bills

Flat roofs have a bad reputation in terms of energy efficiency. We have built in a warm deck insulation system as standard with our Flat Roof solutions so your room is warmer in the winter and cooler in the summer, also saving you thousands on your heating bills.

Your peace of mind. Guaranteed

excellent from start to finish

From start to finish the service we received was first class. Just one little think that I think should be pointed out to customers at the start of their journey is that occasionally there will be moisture on the outside of the window in damp cool weather. Other than that the service was first class and the workers were very careful when working through out our home

On time, had cloths on floor and stairs, worked straight through, nice men.

Yes, I would buy from them again. The salesman who came to our apt. demonstrated the window, showed all the features and wasn’t pushy. The product sold itself and has turned out exactly what we needed and hoped for.

The door and fitting was carried out quickly with little fuss and no issues

The two guys were very professional and left no mess and the job was completed in good time and I was kept up to date on the progress as I was in work whilst it was going on.
