The benefits of flat roofing

While sloped roofs remain the most popular choice for residential buildings, flat roofs are still a common option for many commercial properties. They are also widely used on domestic extensions and outbuildings, while architects are increasingly incorporating flat roofing on modern homes as an attractive and eco-friendly design feature.

Flat roofs may have had something of a bad reputation in the past, but you may be surprised to discover that they can actually offer substantial benefits. Meanwhile, modern design and materials mean you don’t need to worry about rainwater pooling and leaking as you may have done previously.

Here are our top four flat roofing benefits that make it so popular with homes and businesses across the UK.

Low cost

Flat roofing is much quicker and easier to install than pitched roofing, and with a smaller overall surface area, it also requires fewer materials. Those factors mean that it’s generally considerably cheaper to install as well. 

Of course, just because it’s a cheaper roofing option, don’t make the mistake of thinking that it is necessarily going to be lower quality as well. Modern types of flat roofing use strong and durable materials in their construction, such as EPDM rubber roofs that come with a guarantee of 20 years or more to give you real peace of mind that you’re getting both reliability and value for money.

Easy maintenance

As well as being cheaper and easier to install, flat roofing is nearly always easier to maintain as well. After all, when you need to work on it, you don’t need to worry about putting up scaffolding to do the job safely – most of the time, you can just get a ladder and climb up to get access.

That could also mean that you’re likely to save money on costly repairs in the long run, as it should be easier to keep a close eye on its condition. That will give you a better chance of spotting developing issues and dealing with them before they deteriorate to the point that more substantial work is required.


They may not have the internal storage you get when you have a loft, but flat roofs still offer possibilities that you don’t get with pitched roofs. For commercial buildings, that could mean providing somewhere out of the way to place air-conditioning units or other large items that would otherwise take up valuable space inside. It’s also relatively easy to install solar panels that could significantly reduce your running costs by generating your own clean electricity. In residential buildings, a flat roof could be somewhere to put in a roof garden that both provides an outside space for owners to relax in and improves the insulation of your home.

Energy efficiency

With so many options for materials that can be used on flat roofs, it’s sensible to use those that give you the most thermally efficient results. That can mean you’re hopefully going to be saving money on both heating your premises in winter and cooling them during a hot summer. Of course, you need to make sure that you’re using an experienced flat roofing company that knows how to carry out the work so that you’re getting the best results out of the materials and construction at hand.

How long will my project take?

Each project is different and the size of the build will determine the time it will take to complete; however, an average rear extension/loft conversion will take approximately six weeks from start to finish.

Will I be able to live in my property while the work goes on?

Yes, you will be able to live in the property. If this is the case, we will attempt to leave the breaking through into the house until as late as possible in the project.

Will someone be on site every day?

Yes, we will have someone on site every day. However, the caveat to this is if we are waiting on drying times or materials. That being said, we will endeavour to have a team member/team members present as much as possible to ensure the project is completed in a timely manner.

Will an extension add value to my property?

Absolutely, it is becoming more and more popular to add space to your existing property instead of the hassle and fees involved with moving. Adding additional square meterage can add up to 10-20% onto the market value.

Can you help with plans/designs?

Of course, we can offer suggestions and ideas, and show you previous projects. We can also arrange for you to visit a previous project if required. We have built relationships with trusted architects and can introduce you to our preferred contacts in order to obtain your drawings.

How long does it take to get planning permission?

It will depend upon whether you are applying for permitted planning or full planning permission. Different councils work to different timescales; however, as a guide from submission of plans it will take approximately 8-12 weeks.
