Why many flat roof jobs land with Fell Roofing
GRP done as a full system
Deck preparation, falls and edge details all matter if a GRP roof is going to last well.
Material choice with a reason
We compare GRP, EPDM and felt around use, drainage and long-term upkeep.
Honest repair guidance
If a local fix makes sense, we say so. If the roof is spent, we say that as well.
Flat roofs need sound details, not wishful thinking
A flat or low-pitch roof only behaves well when the deck, falls, outlets and edge details all do their job together. If even one of those parts is weak, water finds a way to sit, creep or return. With Fell Roofing, flat roofing work covers installation, repair, maintenance and full replacement using GRP fibreglass, EPDM rubber and felt systems. We look at how the roof is used, what condition the substrate is in, how drainage currently behaves and how much upkeep you want to deal with over time. That matters whether the roof sits over an extension, porch, garage, balcony, outbuilding, utility room or a commercial property with regular exposure to standing water and harsh weather.
Repair, recover or replace with the right system
GRP is a strong option where you want a seamless, joint-free finish with minimal upkeep and a lifespan of more than 25 years, and advertised systems start from £999. That said, not every flat roof needs starting again. Some faults can be handled with a targeted repair, while others call for recovering or full replacement because the deck, drainage or waterproof layers have already had enough.

Frequently asked questions
Is GRP the best choice for every flat roof?
Not automatically. GRP is an excellent option where you want a seamless finish, strong leak resistance and low upkeep, but the right system also depends on the roof use, substrate condition, drainage layout and budget. We assess those points before suggesting GRP, EPDM or felt for the job.
How do I know if my flat roof needs repair or full replacement?
If the problem is isolated and the main roof build-up is still sound, a repair may be enough. If the roof has widespread deterioration, poor falls, weak joints or repeated leaks from more than one point, replacement is often the more sensible route. The decision rests on condition, not guesswork.
What affects the price of a flat roof job?
Size matters, but so do deck condition, access, required edge details, outlets, the chosen material and whether the job involves repair, recovering or full replacement. Where GRP is suitable, systems start from £999, but a proper site look is still the best way to price the work fairly.
