Frequently Asked Questions
Answers to common questions about flat roof installation, replacement and repairs.
Which flat roofing system is best?
The most suitable system depends on the property, roof layout, condition of the existing structure and available budget. EPDM rubber, fibreglass and modern felt systems can all provide reliable protection when correctly specified and installed.
Can a leaking flat roof be repaired?
In many cases, yes. If the problem is limited to an isolated split, damaged flashing or a small affected area, a targeted repair may be appropriate. If the roof covering has deteriorated extensively, replacement may offer better long-term value.
How much does a new flat roof cost?
The cost depends on the size of the roof, the selected material, access requirements, the condition of the roof deck and whether the existing covering needs to be removed. We inspect the property and provide a clear quotation before work begins.
Do you install EPDM rubber roofing?
Yes. We install EPDM rubber roofing systems where suitable for the property. EPDM is commonly chosen for garages, extensions and other domestic flat roofs because it offers a durable, flexible roofing membrane.
What is fibreglass GRP roofing?
GRP stands for glass-reinforced plastic. It is a fibreglass roofing system that creates a strong, smooth and weather-resistant finished surface when installed correctly.
Should water sit on a flat roof?
Flat roofs should be designed to allow water to drain. Persistent pooling can indicate drainage problems, an insufficient fall, blocked outlets or deterioration within the roof structure. If water remains on the roof regularly, it is sensible to have the area inspected.
Can you replace a garage flat roof?
Yes. We repair and replace garage flat roofs using suitable roofing systems, including felt, fibreglass and EPDM rubber, depending on the roof structure and your requirements.
Which areas of South Wales do you cover?
We provide flat roofing services throughout South Wales, including Bridgend, Cardiff, Cowbridge, Penarth, Pencoed, Pontyclun, Pontypridd, Caerphilly, Swansea and the Vale of Glamorgan.
