How Long a Flat Roof Lasts

Most extension roofs are Flat. How long they last can depend on a number of things.

Lifespan by Material

Felt roofs last around 10 to 15 years. High quality EPDM rubber roofs last for around 25 to 30 years. Fibreglass GRP roofs can last for 25 years or more. Liquid coatings to flat roofs can last around 20 to 25 years and are relatively easy to maintain.

Installation Makes a Difference

So long as the joins, edges and upstands are all properly sealed, then a qualified roofer should be able to get all of the relevant details correct the first time round.

Keep Drainage Clear

The main enemy of a flat roof is standing water. Regularly check that outlets and gutters are clear, ideally twice a year, especially after the autumn leaf fall.

Inspect Regularly

It’s worth checking your roof every Spring and Autumn to look for signs of blisters, cracks and lifted edges. This will enable you to pick up any problems before they cost too much to put right. The damp winters in Hampshire make it especially important to carry out these checks.

Know When to Replace

Ponding, cracking and interior damp patches can be signs that a roof needs to be replaced. However, it is also worth checking if replacement of the roof would require planning permission and whether it would fall within the relevant permitted development provisions for flat roofs.

So with the right choice of roof and regular maintenance, your flat roof can last for decades to come.
