Old felt flat roofs crack, blister and pond water. A modern system laid on a new deck will last decades with almost no maintenance.
We will recommend the right system for the roof — rubber, fibreglass or high-performance felt — and explain the difference in cost and lifespan.

Flat Roofing: common questions
Which flat roof system is best?
EPDM is excellent value and very durable; GRP gives a hard, walkable finish and is great for complex shapes; felt is the budget choice. We will recommend what suits your roof.
How long does a flat roof last?
A properly installed EPDM or GRP roof typically lasts 25 years or more.
Can you add insulation to my flat roof?
Yes. Converting to a warm roof when replacing the covering improves energy efficiency and helps prevent condensation.
