Planned around the roof you actually have
Clear assessment before specification
We look at the existing flat roof, its condition and the details around it before recommending a system
Felt and GRP options
We can discuss traditional felt and liquid GRP systems according to the roof, its construction and the work required
Work focused on the whole detail
The covering is only part of a flat roof. We pay attention to edges, outlets, junctions and other areas where water needs to move correctly
Felt flat roofing for practical roof renewal
Flat roofs need more than a new surface laid over an existing problem. If the covering has deteriorated, water is ponding or previous repairs are beginning to fail, we assess the roof and identify what needs attention before work starts. Felt roofing provides a practical waterproofing system for suitable flat roof applications, with the specification determined by the roof construction and its condition.
Where renewal is appropriate, we can strip back the existing covering as needed so we can assess the exposed roof. We then prepare the surface and install the agreed felt system with careful attention to laps, edges, outlets and junctions. The aim is to create a continuous weatherproof covering rather than simply conceal the area where water has previously entered.


Liquid GRP roofing with attention to the details
Liquid GRP roofing provides another option for suitable flat roofs, forming a seamless reinforced waterproofing system around the roof surface and its more difficult details. It can be particularly useful where the roof has awkward junctions, penetrations or areas that need a carefully formed finish.
The installation process involves preparing the existing roof structure, applying the specified GRP system and forming the waterproofing around the relevant edges and details. Drainage remains important throughout the work, so outlets and changes in level need to be considered as part of the complete roof rather than treated as separate features. Wills Brothers Roofing Limited explains the proposed system and scope clearly before work begins, so you know what is being renewed and why.
Frequently asked questions
What types of flat roofing do you provide?
We provide felt flat roofing and liquid GRP roofing for suitable applications. The most appropriate system depends on the roof construction, existing condition, detailing and required scope of work.
Is felt or liquid GRP better for a flat roof?
Neither system is automatically right for every roof. We assess the existing construction and the areas requiring renewal before recommending a suitable approach. We can explain the practical differences between the options as part of the quotation.
Can you replace a leaking flat roof?
Yes. We can assess the source and extent of the problem before determining whether the existing covering can be repaired or whether a more substantial renewal is appropriate. We also consider surrounding details and drainage rather than focusing only on the visible leak.
