Torch-on felt flat roof installation on a Hull property
The Two Systems We Fit

GRP Fibreglass and Torch-On Felt, Explained Plainly

GRP fibreglass is laid as a liquid resin with glass matting, curing into a single continuous surface with no seams across the main area. That seamless skin is why it suits the low-pitch and completely flat roofs common on Hull garages and extensions, and why it shrugs off standing water that defeats older coverings.

Torch-on felt is built up in layers of high performance membrane, torched and bonded to the deck. It remains a well proven, practical covering, and on some roofs and budgets it is the right call. We fit both systems, so our recommendation is based on your roof, not our stockroom.

Repair It or Replace It

The honest answer depends on the state of the covering and the deck beneath it. Here is how we judge a flat roof when we stand on it.

When a Repair Is Enough

A localised split, a failed detail at an edge, or a problem around an outlet can be repaired properly and give the roof years more life. These jobs feed into our wider roof repairs in Hull service, with a free quote before anything starts.

When Replacement Is the Honest Answer

Blisters across the whole surface, a deck that flexes or has rotted, or a covering already patched several times. At that point repairs are wasted money, and we will say so at the inspection rather than sell you a job that fails next winter.

If a storm lifted a flat roof tonight, that is a job for our 24/7 emergency page, and the phone is answered around the clock.

Where We Fit Flat Roofs in Hull

Most of the flat roofs we lay around the city sit on domestic buildings like these.

Garage Roofs

Extensions

Dormers

Outbuildings

While the flat roof is being renewed we can also check the edges it meets, and if the boards at the roofline are past their best, our fascias and soffits in Hull service covers the replacement.

Flat Roofing Hull FAQs

What is GRP fibreglass roofing?

GRP stands for glass reinforced plastic, a fibreglass system laid in one continuous coating on your roof deck. It cures with no joints or seams across the main area, which is what makes it such a popular choice for flat roofs on garages, extensions and dormers.

Is felt still a good flat roof covering?

Yes, when it is fitted properly. Modern high performance torch-on felt is a long way from the old pour and roll materials people remember, and it remains a practical, well proven covering for flat roofs. We use quality materials and fit them to a standard we would accept on our own homes.

GRP or felt: which should I choose for my flat roof?

It depends on the roof, the budget and the use of the building, and that is a conversation worth having before you commit. Both systems are everyday work for us, so our advice is based on what we see lasting around Hull, not on pushing one product.

Can you repair my existing flat roof?

Usually, yes. We find the fault, whether it is a split in the covering, a failed edge or corner detail, a problem around an outlet, or movement in the deck joint, and repair it properly. If the deck underneath has rotted or the covering is beyond saving, we will say so and quote for a replacement instead of taking money for a repair that will not last.

How long does a flat roof take to replace?

Most domestic flat roofs, a typical garage or extension for example, are stripped and renewed within a working day or two once materials are on site. Weather matters, especially for fibreglass curing and felt work, so we book around the forecast rather than rushing a roof on in the rain.

Do you cover flat roofing work outside Hull?

Yes. Alongside Kingston upon Hull we cover Beverley, Cottingham and the wider East Riding of Yorkshire, working within roughly a 20-mile radius. If your flat roof is just outside that, call 07375 366681 and ask, we would rather say yes than lose a local job.
