Flat Roof Services in Surrey & the South East

Fully guaranteed flat roof solutions

Felt, Rubber (EPDM), GRP and More

At Crown Roofers, we provide expert flat roof installation, repair, and renovation services for homes and commercial properties across Surrey and the South East. Whether you need a durable new flat roof for a home extension, garage, or outbuilding—or repairs to an ageing system—our experienced team delivers long-lasting solutions using high-performance materials.

We work with a wide range of flat roofing systems, including traditional felt, advanced EPDM rubber, and modern GRP fibreglass. Every project is carried out to the highest standard and backed by our workmanship guarantee.

Why Choose a Flat Roof?

Flat roofs are a popular and cost-effective option for:

  • Rear or side extensions
  • Garages and carports
  • Porches
  • Dormers and loft conversions
  • Garden rooms and sheds
  • Commercial buildings

They offer a low-profile appearance, easy access for maintenance, and are often quicker to install than pitched roofs. With modern materials, flat roofs can now rival pitched roofs in terms of durability, insulation, and performance.

Materials We Use

Frequently Asked Questions –
New Roofs

How long does a flat roof last?2025-07-25T15:17:36+00:00

This depends on the material used. Felt roofs can last 10–15 years, EPDM rubber often lasts 20–30+ years, and GRP fibreglass may exceed 30 years with proper care.

Are flat roofs prone to leaking?2025-07-25T15:17:56+00:00

Not if installed correctly. Modern flat roofing materials are designed to be completely watertight. Proper installation, good drainage, and regular maintenance are key to avoiding leaks.

Can a flat roof be insulated?2025-07-25T15:18:19+00:00

Yes. We can install warm or cold deck insulation systems to improve thermal performance and reduce energy bills. Warm roofs are particularly popular for extensions.

How much does a flat roof cost?2025-07-25T15:18:39+00:00

Costs vary depending on size, material, and access requirements. We’re happy to provide a tailored, free quote with no obligation.

Do I need planning permission for a flat roof?2025-07-25T15:18:57+00:00

In most cases, no—especially for repairs or replacements. However, large-scale projects or listed buildings may require consent. We can guide you through this if needed.
