J&S Roofing & Bricklaying is proud to serve as a local specialist for the repair, replacement, and maintenance of flat roofs across Swindon, Marlborough, and all nearby locations listed on our Areas We Cover page. Whether you’re a domestic or commercial client, we’re a roofer capable of keeping flat roofs in top condition, whatever the weather throws their way.

Flat roofs are a popular choice for house extensions, kitchen refurbishments, and side extensions, offering a sleek, modern look and practical space utilisation. We work with a variety of materials to suit your needs, including felt roofing, EPDM roofing, lead roofing, and fibreglass roofing, and offer a range of helpful guttering services should you be also looking to upgrade your roofline alongside flat roofs.

Felt roofing is one of the most traditional materials used for flat roofs. Made from layers of bitumen felt, they’re best known for their cost-effectiveness, and both ease-of-installation and repair. They’re a great choice for home and business owners around Swindon and Marlborough who may be on a budget. When it comes to repair and maintenance, some common issues experienced by felt flat roofs include:

  • Ponding water due to poor drainage.
  • Blistering due to trapped air or moisture.
  • Cracking over time, particularly in older roofs.
  • Lifting at the edges, especially in high winds.

EPDM flat roofs are made from a modern, highly durable rubber roofing membrane. They’re a popular choice for flat roofs because of their resistance to UV rays and high temperatures. EPDM roofing is also eco-friendly and has a long lifespan, often exceeding 20 years with proper maintenance. This makes it an ideal choice for clients in Swindon and Marlborough looking for a long-term solution. Some common issues our roofers address with EPDM roofing include:

  • Adhesion issues, particularly in colder weather.
  • Shrinkage over time, leading to gaps or cracks.
  • Punctures from sharp objects or foot traffic.
  • Poor installation, leading to water infiltration.

Lead roofing is renowned for its longevity and classic appearance, making it a preferred option for traditional and historic buildings in Marlborough and Swindon. Lead is incredibly durable and can last over a century when properly maintained. Its malleability also allows it to conform to various roof shapes, making it ideal for complex roof designs. Common issues with lead flat roofs include:

  • Potential for sagging if not supported adequately.
  • Expansion and contraction leading to cracks.
  • Corrosion in areas exposed to acidic rain.

Fibreglass roofing, also known as GRP (Glass Reinforced Plastic) roofing, is a strong, lightweight, and waterproof material. It’s an excellent option for flat roofs due to its seamless finish and resistance to water and fire. Fiberglass roofing is ideal for extensions and refurbishments in Swindon and Marlborough, providing a modern and durable roofing solution. Some common roof repairs our roofers undertake for fibreglass systems include:

  • Cracking due to expansion and contraction.
  • Fading or discolouration from UV exposure.
  • Again, poor installation from sub-par roofers leading to leaks.

It depends on your needs. EPDM is long-lasting and eco-friendly, fibreglass (GRP) offers a seamless and durable finish, felt is budget-friendly, and lead is ideal for heritage properties.

With proper installation and maintenance, flat roofs can last anywhere from 10 to over 40 years. EPDM and fibreglass roofs generally offer the longest lifespan.
