Flat Roofing FAQs

What is flat roofing?

Flat roofing refers to a roof design that appears level but actually has a slight fall (usually 1–10°) to allow rainwater to drain away. Flat roofs are commonly used on:

  • House extensions
  • Garages
  • Porches
  • Garden rooms
  • Commercial buildings

Unlike pitched roofs, flat roofs rely heavily on the quality of materials, installation, and drainage design to remain watertight.

What are the benefits of flat roofing?

Flat roofing offers several advantages, including lower installation costs compared to pitched roofs, a modern and clean appearance, and efficient use of space. Flat roofs are ideal for installing roof lights, solar panels, or green roofs, and they are easier to access for maintenance and inspections than on pitched roofs.

What materials can be used for flat roofing?

Several materials are commonly used for flat roofing, including:

  • Felt roofing – a traditional and cost-effective option
  • EPDM rubber roofing – durable, flexible, and low maintenance
  • GRP fibreglass roofing – strong, seamless, and long-lasting
  • Single-ply membranes (PVC or TPO) – lightweight and often used on larger or commercial roofs

The best material depends on your budget, roof size, and how the roof will be used. Speak to an expert at S&J roofing today for advice tailored to your needs.

What are common flat roof problems?

Common flat roof problems include ponding water, cracks or splits in the membrane, blistering caused by trapped moisture, and leaks around roof edges, skylights, or drainage outlets. Most issues are caused by ageing materials, poor installation, or blocked drainage rather than the flat roof design itself.

If you are experiencing issues with your flat roofing system get in touch with our team at S&J Roofing for expert advice and repairs.

How long does a flat roof last?

The lifespan of a flat roof depends on the material used and how well it is maintained. Felt roofs typically last 10–20 years, while EPDM rubber and GRP fibreglass roofs can last 25–40 years. Regular inspections and timely repairs can significantly extend the life of a flat roof.

How to repair a flat roof?

Flat roof repairs depend on the type and extent of damage. Minor issues such as small cracks or localised leaks can often be patched or sealed. More serious problems, including widespread leaks or water-damaged decking, may require partial or full roof replacement. A professional inspection is recommended to identify the most cost-effective solution.

Do flat roofs leak easily?

No, a properly installed flat roof should not leak. Most leaks occur due to poor workmanship, ageing materials, or lack of maintenance. Modern flat roofing systems are highly reliable when fitted by an experienced roofer.

If you need an experienced and trusted team of roofers to install or repair your flat roof get in touch today.

Is a flat roof waterproof?

Yes, flat roofs are designed to be fully waterproof. Although they appear level, they include a slight slope to direct water towards drainage points and prevent standing water.

Do flat roofs need maintenance?

Flat roofs should be inspected at least once a year and after severe weather. Keeping outlets clear and addressing small issues early helps prevent costly repairs and extends the roof’s lifespan.

Can a flat roof be insulated?

Yes, flat roofs can be insulated using either warm roof or cold roof systems. Proper insulation improves energy efficiency, helps prevent condensation, and ensures compliance with current building regulations.

S&J re-roofed our 1960’s house during September. The service was excellent from start to finish. Everyone we dealt with at S&J was polite, courteous and helpful. We chose them because they were a long established local family business with a good track record offered a 25yr guarantee and they had done a good job on a neighbour house . On our house they removed the existing tiles, battons very damaged felt liner. They installed a new breathable lining, new battons and we opted for new tiles.. we are very pleased with the outcome. Thanks to Lee, Naomi, Tom, James, Kye, Scott, Cam and Jay…. You made it a painless experience

If it were possible to give a higher than 5* review, I would be more than happy to do so. Prior to instructing a company to do my roof renewals, I obtained five quotes. These quotes were from reputable Bath specialist roofing companies, all with a minimum of 4.6 plus reviews. S&J Roofing were the last company I met with, by this time I had already instructed another company. I was so impressed after meeting with the Director of S&J, Lee Shellard, that I cancelled the other company I’d already instructed (forgoing my deposit.) Before starting the work Lee encouraged me to come into the Walcot Street shop, so I could see all the materials that would be used on my roof and check I was happy before the work commenced. Throughout the project I could not have been happier with how the work was carried out. The S&J team were, polite, tidy on site, worked extremely hard even in the summer heatwave. They were always happy to answer questions and kept in constant communication regarding the work that had been done and completion timings. They completed the work on time and left the site immaculately tidy. I’m so grateful that I decided to instruct S&J and would not hesitate to recommend them. They are absolute professionals and a brilliant example of a specialist family-run company, who really care about the work they do and how they conduct their business. My sincerest thanks, to all the S&J team.

⭐⭐⭐⭐⭐ S&J Roofing Bath recently carried out work on my property and I couldn’t be happier with the result. The workmanship was exceptional, and the communication was excellent from the moment I first made an enquiry right through to the finished project. Everything was handled professionally, the work was completed to a very high standard, and I was kept informed throughout the whole process. Highly recommend!

S&J re-roofed our Grade I listed roof with real expertise and professionalism. The project could genuinely not have gone any better. The attention to detail of tricky construction interfaces showed real care and the weekly progress updates kept us informed along the whole process. Thanks to Lee and the whole S&J team to a tricky job very well done.

What an amazing experience dealing with Lee and his team at S&J Roofing in Bath. Not only were they responsive from the first contact but kept me in the loop on every aspect of the tricky historical roof. Which they repaired, with like for like materials and even went above and beyond by going to a reclamation yard to get historical coping stones that had been broken by the previous roofers. My new neighbours have all commented on how professional his team were and have all told me they filed away S&J’s contact details, As they wouldn’t think of using any other roofing company in Bath. Their work is simply superb And I wouldn’t hesitate to highly recommend them to anybody. Thank you, Lee and the team. ❤️
