Common Questions

What is a flat roof?

A flat roof is a roof which has an angle or pitch below 10°. Whereas a sloped roof appears to have a significant slope on either side, a flat roof appears level throughout.  

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.

What are flat roofing materials?

Flat roofing materials are purposely designed for use on roofs with an angle or pitch below 10°. Unlike other materials, these can withstand the unique challenges faced by flat roofs, such as severe UV, standing water or resting debris.

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

What is the best material for a flat roof?

The most popular type of flat roofing material are rubber membranes. These membranes, which are often referred to as EPDM, can easily handle standing water and resting debris. This is due to the thick rubber being resistant to UV and watertight.

When using a rubber membrane, you will require a range of flashings. 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 material used and which flashings 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 significantly more labour time being necessary.

What is the life expectancy of a flat roof?

The life expectancy of a flat roof can vary hugely. This is as it is dependent upon the fitting methods followed and 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 poor seams. Small tears in the rubber membrane may also cause severe water damage over a prolonged period of time.
