Common Questions

What is a Flat Roof?

A flat roof has a pitch below 10° and appears virtually flat throughout. This is opposed to a pitched roof, which has a pitch above 10° and appears to have a significant slope on either side. 

Flat roofs are common due to them being easy to construct and cost-effective. It is for this reason that extensions, garages and garden buildings often feature a flat roof. Although, it is important to note that not all roofing supplies can be used on a flat roof. 

What Are Flat Roof Materials?

Flat roof materials are purposely designed for use on roofs with a pitch below 10°. Unlike other materials, these can withstand the unique challenges faced by flat roofs. These challenges include severe UV, resting debris and standing water.

Other roofing supplies, such as roof tiles, would not be able to withstand such challenges. You would therefore face leaks, sagging and other structural issues if you were to use these materials on a flat roof.

The most common type of flat roof material are rubber membranes. These are manufactured from a unique formula of ethylene, propylene and diene comonomer. This provides you with a lightweight yet durable solution for your flat roof. 

What is the Best Material for a Flat Roof?

The most popular type of flat roof material are rubber membranes. These membranes, which are often referred to as EPDM membranes, can easily withstand standing water and resting debris. They can also handle the impact of severe heat and UV rays. 

When using a rubber membrane, you will require a range of accessories. Whilst these can be purchase separately, you can use our flat roof kit builder for added convenience. This will calculate all the supplies you’ll require for your flat roof.

How Much Does It Cost to Replace a Flat Roof?

If using a rubber membrane, you can expect a flat roof replacement to cost between £10 - £20 per square meter. However, the total cost can be dependent upon the exact flat roof material used and which accessories you require.

When replacing a flat roof other factors may also impact the overall cost. For example, the introduction of a skylight can inflate the cost significantly due to more labour time being necessary.

What is the Life Expectancy of a Flat Roof?

The life expectancy of a flat roof can vary. This is as it is dependent upon the fitting methods followed and flat roof supplies used. However, if using a reputable rubber membrane you can typically expect a lifespan of up to 35 years.

The biggest cause of flat roof failure is leaks. This is usually caused by poor drainage or faulty seams. Small tears in the rubber membrane may also cause severe water damage over a prolonged period of time. They should therefore be spotted and rectified quickly.
