Flat Roofs Built To Cope With Devon Weather
A flat roof works considerably harder than a pitched one. Rain does not simply run off it, and Exeter sees a good deal of rain. In our experience, flat roofs rarely fail across the middle of the covering. They fail at the perimeter, around the outlets, and at the junctions where the roof meets a wall.
That is where our attention goes first. We establish the condition of the deck, confirm where the water is intended to drain, and identify what is preventing it. Once that is understood, specifying the right covering, whether rubber, fibreglass or felt, becomes far more straightforward.
We work across Exeter and the wider Devon area on domestic, commercial and industrial property, from single garages and rear extensions through to dormers, balconies and flat-roofed commercial units.

Why choose us
An Honest Assessment First
Many of the enquiries we receive come from property owners who have already been told their roof needs replacing in full. Sometimes that is correct. Frequently it is not. A single split seam or a blocked outlet can put water through a ceiling on a covering with years of service left in it, and you are entitled to know which applies before committing to the work.
Our flat roofing sits alongside the pitched roofing, leadwork and chimney work we carry out across Devon. That breadth matters, because problems on a flat roof almost always begin at the junctions with the rest of the building.
Accurate leak tracing
Water rarely enters where the damp appears. We identify the true point of entry before quoting for any remedial work.
The right system for the roof
EPDM, GRP or felt, specified according to the size, access and intended use of your roof rather than ease of installation.
Domestic and commercial
From single garages and rear extensions through to flat-roofed commercial and industrial premises.

Flat roofing questions
Frequently Asked Questions
The questions we are asked most often about flat roofing in Exeter.
How long does a flat roof last in Exeter?
Most flat roofing lasts between 20 and 40 years, though the figure depends heavily on the system installed and the maintenance it receives. Exeter's wet climate makes drainage particularly important, and keeping outlets clear has a greater effect on lifespan than many property owners expect.
Which flat roofing system is best for my property?
No single system suits every roof. The right choice depends on the size and shape of the roof, whether it needs to carry foot traffic, how it meets the surrounding walls, and your budget. EPDM rubber suits most domestic extensions and garages, GRP fibreglass is the stronger option for balconies and walk-on areas, and torch-on felt remains economical on larger roofs. We inspect the roof before making a recommendation.
Can a flat roof be repaired, or does it need replacing?
Localised faults such as a split seam, a blister or a failed upstand can usually be cut out and repaired without disturbing the rest of the roof. Replacement becomes the better option once a covering has reached the end of its life, where the deck beneath has decayed, or where leaks continue to appear in new positions. We will advise you which of these applies, including when the smaller job is sufficient.
Why is water sitting on my flat roof?
A flat roof should never be entirely level. It is built with a slight fall so that water runs to the outlets. Standing water, known as ponding, usually indicates insufficient fall, a deck that has begun to sag, or a blocked outlet. Because it places the covering under constant load and accelerates wear, it is worth investigating rather than leaving.
Do you work on commercial flat roofs as well as homes?
Yes. We carry out flat roofing work on domestic, commercial and industrial premises. Larger roofs bring additional considerations around access and detailing, but the approach is the same throughout: inspect the roof properly, explain what we have found, and specify a system appropriate to the building.
