Flat Roofing in Arundel

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 Arundel

Arundel is one of West Sussex's most distinctive towns — dominated by its medieval castle and Gothic cathedral, with a dense concentration of listed buildings and conservation-area properties that require specialist roofing expertise and careful attention to planning requirements. The town sits in the Arun valley at the foot of the South Downs, creating a sheltered microclimate that nevertheless experiences high rainfall funnelled along the valley corridor from the south-west. Working on heritage properties in Arundel requires knowledge of traditional materials and techniques that not all roofers possess. Natural Welsh slate, plain clay tiles, stone slates, and lime mortar pointing are all common requirements in the older streets, and any repair or replacement work on listed buildings must use appropriate matching materials and — in many cases — receive prior approval from the local planning authority. West Sussex Roofing have extensive experience navigating these requirements and can advise on appropriate routes from the outset. We cover all of Arundel and the Arun valley including Ford, Yapton, Walberton, and the surrounding villages. We provide free written surveys, planning guidance where relevant, and fixed-price quotations for all roofing work from conservation-area repairs to full modern replacements on newer properties.

Flat Roofing in Arundel — 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.
