Flat Roofing in Worthing

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 Worthing

Worthing's coastal location means roofs here take some of the hardest punishment in the region — salt-laden winds, driving rain, and the occasional storm event accelerate deterioration significantly compared to inland properties. Regular inspection and maintenance is particularly valuable for Worthing homeowners. West Sussex Roofing operate throughout Worthing, Lancing, Shoreham-by-Sea, and Findon, providing full roof replacements, repairs, flat roofing for seafront properties, and comprehensive gutter and fascia work. We stock a range of materials specified for coastal environments and advise on appropriate finishes to maximise service life in exposed locations.

  • EPDM rubber membrane for flexible applications
  • Correct drainage design and fall configuration included

Flat Roofing in Worthing — 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.
