What is Flat Roofing?

The term ‘flat roofing’ describes a roof surface that is completely or almost level. Although they’re described as flat, more often than not these roofs are actually laid at a slight angle to allow for the drainage of rainwater. Typically, they are designed to have a minimum fall of 1:40, but this can vary anywhere to 1:80, depending on the site upon which the structure has been built.

In the UK, flat roofs are commonly found on outdoor living or storage spaces, house extensions and industrial buildings. It’s a very popular style and has been gaining popularity with architects for houses with a more modern, minimalist design.

 

Types of Flat Roofing

When searching around for ‘Flat Roofing Bristol‘, you’ll more than likely find a wide range of materials available and which one you require will come down to personal preference. There isn’t an industry consensus on which one yields the best results.

The most important thing to think about when choosing the material for your flat roofing is the price and the guarantee provided by the manufacturer. Here at The Roofing Company Bristol, we’re a registered member of the NFRC and can offer you up to 25 years guarantee on our flat roofs to ensure longevity.

It’s also important to think about the material performance, the complexity of the structure and the overall aesthetic appeal it’ll bring.

 

Torch-On Felt

Torch-on Felt covering consists of two or three layers of bitumen sheet, which is applied to the roof using a gas torch. This is a very common, cost-effective option.

One of the main advantages of using torch-on felt to cover a flat roof is its malleability and multi-layering which really helps it stand up well to foot traffic and general weathering.

 

GRP/Fibreglass Roofing

GRP/fibreglass is an extremely versatile option for flat roofing, which works well on any roof, especially ones that are not of standard shape or size. It’s lightweight, yet strong and durable and can be excellent for domestic and commercial buildings that need to withstand footfall.

 

What are the Advantages of Choosing a Flat Roof?

Flat roofs are a popular choice for three distinct reasons. Their aesthetic, price-point and low maintenance.

  • Design: Flat Roofs are a great choice for both small and large structures,  most commonly being used on extensions, garages, airports and supermarkets. Their highly waterproof membranes will also protect the structure and a flat roof also creates more space inside the structure compared to pitch roofing. This makes the most out of the dimensions of a building of any size.
  • Cost: When installing a flat roof, fewer materials will generally be used, making it considerably cheaper to install than a pitched roof. The installation time will also be significantly shorter, with smaller buildings being completed in just a couple days.
  • Low Maintenance: A flat roof will typically be a lot easier to inspect and repair than a pitched roof.

Common Flat Roofing Problems We Face in Bristol

Some of the common flat roofing problems we have worked with and fixed across Bristol include;

Ponding Water

Flat roofs don’t drain as well as pitched roofs, which is why they commonly develop ponding water. Ponding water is water that stands in a puddle on your roof for more than 48 hours or more.

This issue will only develop if the water remains on the roof for an extended period, wearing down the membrane. This can resultantly cause leaking.

Blistering

Blistering is caused when small pockets of air or moisture get trapped either beneath the membrane of in between layers of the membrane. This will then worsen when the roof warms up in the sun, causing the pockets of air or moisture to expand and stretch out the membrane.

Alligatoring

Alligatoring describes the cracking of a coating or surface bitumen on a flat roof. This, therefore, causes a pattern similar to the hide of an alligator. This can be caused by water, debris or a long term exposure to the sun.

This cracking will eventually split further if left unrepaired, meaning that more water can get in and cause leaking, moisture and even more damage.

Buckle in Membrane

Any house will move and settle over time. However, this does mean that the roofing membrane will move too. Typically, the membrane will only consist of a single sheet, so when the roof moves, this sheet will buckle.

Thermal Movement

Temperature changes can cause the roofing material to expand and contract, which is relatively normal. However, continual expansion and contraction can weaken the roof, causing leaks. This movement can occur on the flashing, causing it to move away from the edges of the roof, allowing water into the roof.

If you have noticed any of the above problems, make sure to get in touch with one of our Bristol-based experts today. Making sure that roofing issues are solved proactively can save you a lot of money in the long run, by preventing any small issues developing into bigger ones.

Ways to Prevent Flat Roofing Issues in Bristol

If you are looking to avoid flat roofing leaks, you can:

  • Apply a protective coating to prevent rain from leaking through the roof,
  • Ensure your roof has a good drainage system,
  • Making sure that there is enough roof fall, to enable water to drain off properly.
