FAQs
What types of flat-roof systems do you install in Lancing?
We specialise in three main flat-roof systems: high-performance Torch-On felt, single-ply EPDM rubber, and GRP (glass-reinforced plastic) fibreglass. Each option is fully suited to the coastal climate in Lancing, offers different aesthetic and performance benefits, and comes with manufacturer-backed warranties ranging from 15 to 30 years.
How long should a new flat roof last in Lancing’s coastal conditions?
With correct specification and installation, a Torch-On felt roof typically lasts 15–20 years, an EPDM rubber roof 20–25 years, and a GRP fibreglass roof 25–30 years. All systems are UV-resistant and designed to withstand the salt-laden air and wind exposure common along the Sussex coast.
Do I need planning permission to replace or install a flat roof on my property?
In most cases, replacing an existing flat roof like-for-like falls under Permitted Development, so you won’t need planning permission. However, if you are changing the roof’s height, adding a roof terrace, or working on a listed building or property in a conservation area, you should consult Adur & Worthing Council’s planning department before work begins. We can provide drawings and technical data for any application if required.
How do you ensure proper drainage on a flat roof?
Although called ‘flat’, every roof we install is laid to a minimum fall of 1:80 to channel rainwater toward internal outlets or external guttering. We incorporate tapered insulation schemes, pre-formed GRP drip edges, and, where necessary, new PVCu downpipes to prevent ponding and comply with BS 6229:2018 drainage standards.
What maintenance is required after installation?
Flat roofs are low-maintenance, but we recommend a visual inspection twice a year—ideally in spring and autumn. Clear leaves from outlets, check flashings, and look for surface damage after storms. We offer affordable annual maintenance packages that include a written condition report and any minor remedial work, protecting your warranty.
How much does a new flat roof cost in Lancing, and what factors affect the price?
Prices start from roughly £80 – £110 per square metre for Torch-On felt, £95 – £120 for EPDM rubber, and £110 – £140 for GRP fibreglass, inclusive of labour and 120 mm PIR insulation to meet current Part L energy standards. Final cost depends on roof size, level of insulation required, number of penetrations (skylights, pipe vents), access scaffolding, and any deck repairs.
