Flat Roofing in Graffham

Modern flat roofing systems are far more durable and long-lasting than the old felt that gave flat roofs a bad reputation. West Sussex Roofing install and repair all leading flat roofing systems across West Sussex. Our preferred specification for most residential flat roofs is fibreglass GRP — a seamless, rigid surface built to resist UV, ponding water, foot traffic, and root intrusion. Where flexibility is required we install EPDM rubber membrane, the market-leading commercial flat roof system trusted on buildings worldwide. We also carry out like-for-like felt replacements for heritage properties and temporary structures. Every flat roof installation includes proper drainage design, correct fall configuration, and perimeter edge detailing to the highest waterproofing standard.

About Graffham

Graffham sits tucked under the northern slope of the South Downs between Midhurst and Petworth, a small, well-wooded village of period cottages — flint, brick, and some tile-hung fronts — set among mature trees that shelter it from the wind in a way the more open downland villages don't get. That shelter comes at a cost: heavy tree cover means Graffham roofs deal with a lot more leaf litter, moss, and shaded, slow-drying surfaces than exposed villages further along the Downs, and gutters here need clearing considerably more often to avoid blockages backing up under the tile edges. A number of Graffham's older properties are set on larger rural plots with outbuildings and barns converted for residential use, often with long, low-pitched roofs that were built for agricultural rather than domestic use — these need particular attention to ventilation and underlay when they're brought up to a proper weathertight standard. West Sussex Roofing serve Graffham, Midhurst, and Petworth, with free surveys, gutter clearing, and fixed-price quotations on all roofing work.

Flat Roofing in Graffham — FAQs

How long will a new fibreglass flat roof last?
A properly installed fibreglass GRP roof is a long-lasting, low-maintenance option. Unlike felt, it is fully seamless so there are no joints to fail. Our fibreglass installations come with a written material and workmanship guarantee.
Can I add a rooftop terrace to my flat roof?
In many cases yes, but it requires assessment of the roof structure, planning permission advice, and an appropriate surface specification such as paving on pedestals over a protected membrane. We carry out all of this work and advise on the planning process.
My garage flat roof is bubbling — what does that mean?
Bubbling (blistering) in felt flat roofs indicates the felt has delaminated and moisture is trapped beneath. It is a sign the roof is nearing or past the end of its serviceable life and should be surveyed as soon as possible to prevent water ingress.
