Discover Our Durable Flat Roofing Systems for Every Property

Choosing the right flat roof material for your property is crucial for its longevity and performance. We work with leading modern flat roofing systems, each offering distinct advantages. Our experienced team will help you understand the options and select the perfect fit for your specific needs, whether it's for a garage, extension, or a large commercial flat roof.

  • GRP Fibreglass Roofing: Also known as 'fibreglass roofs', GRP (Glass Reinforced Plastic) creates a tough, seamless, and completely waterproof surface. It's applied cold, making it safe and efficient, and cures to an incredibly durable finish that can withstand heavy foot traffic and extreme weather. Ideal for balconies or areas needing extra resilience.
  • EPDM Rubber Roofing: This single-ply rubber membrane is renowned for its exceptional flexibility and impressive lifespan, often exceeding 50 years. EPDM is UV stable, resistant to extreme temperatures, and incredibly easy to maintain. It’s a popular choice for extensions, dormers, and larger flat roof areas where a robust, long-term solution is preferred.
  • High-Performance Felt Roofing: We install modern, multi-layer torch-on felt systems, a significant advancement from older felt roofs. These systems provide a highly robust and cost-effective waterproof barrier. Applied by our expert team, this method offers superb resistance to tears and punctures, making it a reliable and budget-friendly option for many flat roof replacements.

Why Choose Kevington Roofing for Your Flat Roof Replacement in Ramsden & Bromley?

Our Thorough Flat Roof Replacement Process – Built for Durability

Replacing a flat roof requires precision, expertise, and a meticulous approach. Our process is designed to be as smooth and efficient as possible, causing minimal disruption to your home or business. We start with a comprehensive assessment, then provide a clear, no-obligation quotation. Once you’re happy, our skilled team gets to work:

  1. Safe Removal: We carefully strip away your old flat roof covering, disposing of all waste responsibly.
  2. Decking Inspection: The existing roof deck is thoroughly inspected for any signs of rot or damage, and we repair or replace timber as needed to create a sound foundation.
  3. Insulation Installation: Where appropriate and required, new insulation is fitted to enhance your property's thermal efficiency and help reduce heating bills.
  4. System Installation: The chosen flat roof system – GRP, EPDM, or high-performance felt – is expertly installed to manufacturer specifications, ensuring a flawless, watertight finish.
  5. Finishing Touches: We ensure all edges, upstands, and detailing are perfectly sealed and finished, including checking adjacent gutters and chimney flashings.
  6. Site Clean-up: We leave your property tidy and clear of all debris, so you can enjoy your new, durable flat roof without any hassle.

Identifying the Signs: When Your Flat Roof Needs Replacing

Ignoring a deteriorating flat roof can lead to serious and expensive problems. Here are some common signs that your flat roof might need professional attention and potentially a full replacement:

  • Ponding Water: If water collects and stands on your flat roof for more than 48 hours after rain, it indicates drainage issues or structural sagging.
  • Cracks or Splits: Visible cracks, tears, or blisters in the roofing material are clear signs of failure, allowing water to penetrate.
  • Moss & Algae Growth: Excessive moss can trap moisture against the roof surface, accelerating its deterioration.
  • Water Stains Indoors: Any damp patches, mould, or peeling paint on your ceilings or walls directly below the flat roof are undeniable indicators of a leak.
  • Age: Most older felt flat roofs have a lifespan of 10-20 years. If yours is approaching or past this age, it's wise to consider replacement even if no obvious issues are present.
  • Visible Sagging: A noticeable dip or sagging in the roof surface suggests underlying structural problems.

Flat Roof Replacement FAQs

Frequently Asked Questions

Expert answers to common questions about GRP fibreglass, EPDM rubber, and high-performance felt flat roof replacements in Ramsden, Bromley, and Croydon & South London.

What is the best material for a flat roof replacement in Ramsden?

+

The best material depends on your budget and what you use the roof for. GRP Fibreglass is very popular in Bromley because it is seamless and very tough. EPDM rubber is also a top choice for domestic extensions because it is flexible and has a very long life. We can look at your roof and tell you which one fits your needs best.

How much does a new flat roof cost in the Bromley area?

+

The cost varies depending on the size of the roof and the material you choose. A small garage will cost less than a large extension. We provide free, no-obligation quotes where we break down the costs of labour and materials so you know exactly what you are paying for.

How long will a new GRP or EPDM roof last?

+

Modern flat roofs are designed to last a long time. You can expect a professionally installed EPDM or GRP roof to last upwards of 25 to 30 years. This is much longer than the old felt roofs of the past.

Are you local flat roofing contractors for Ramsden?

+

Yes, we are based in Orpington and cover the whole Ramsden and Bromley area. We have worked on many homes in the local neighbourhood over the last 25 years.
