Flat roof FAQs

  • Rubber membranes (EPDM) and high-quality felt are popular options. Felt roofing is usually cheaper upfront but has a shorter lifespan. Rubber offers longer life, greater flexibility, and better weather resistance, making it a preferred but more expensive choice.

  • Frequent leaks, pooling water or visible membrane damage usually mean repairs are needed. Older flat roofs nearing 20 years or with widespread damage might need replacement.

  • Roof size, materials chosen, condition of underlying structure and any additional repairs required all influence cost. Felt roofs typically cost less than rubber, but rubber lasts longer and requires less maintenance. We provide tailored quotes after surveying your property.

  • Yes, flat roof sealing adds a waterproof layer that can protect and extend your roof’s lifespan when combined with regular maintenance.

  • Yes, we respond promptly to urgent flat roof repairs to prevent further damage.

  • Having read previous reviews and needing my garage flat roof replacing I decided to take a punt and was glad I did. Jay knows his stuff and along with his team including Christie in the office I was kept informed of the job progress from start to finish. No bull or trying to upsell just a good honest job done well and left clean and tidy afterwards. Would not hesitate to use Jay again for future projects.
