Is a flat roof a good idea?
If you need to replace a roof possibly on your garage or maybe you are having an extension built, you will need to decide if you are going to have a flat roof or a pitched roof. There are advantages and disadvantages to having both and below we explain the options in a little more detail to find out which one is right for you and your property.
There are typically two options: pitched and flat. Although the latter is more traditional, flat roofs are definitely making a comeback in contemporary architecture.
Advantages of a flat roof
Flat roofs had a bad reputation in the past. However, thanks to new materials that increase their strength, you’ll see them appear in more places. Speed is one of the reasons why more homeowners are turning to them. Flat roofs are much faster to build than pitched roofs. This is a huge benefit if you want to save money on contractors as well as avoid paying rent on temporary housing during the construction phase. Also, flat roofs require fewer materials, giving them a cost advantage. Flat roofs are often the less expensive option if you’re looking to save money.
Flat roofs are also more compact than pitched roofs, taking up less head height. This may be beneficial if you are converting a garage or building an extension, both of which are subject to planning rules that may limit the height of your project. Though flat roofs do not have the same level of drainage as pitched roofs, they are cleverly designed to prevent water from pooling and flooding your home.
However, there are also some disadvantages that you need to bear in mind. Flat roofs are now commonly made of EPDM, which has increased their lifespan from 20 to 30 years. However, this is still 20 years less than a pitched roof will provide.
Flat roofs will also require significantly more maintenance, resulting in higher day-to-day costs. It’s possible that with maintenance and having to replace it earlier, your flat roof will end up costing more than the initial savings you made during construction.
Pros of a pitched roof
Some people do prefer to opt for a pitched roof instead and often the main reason for this is their longevity. Overall, a pitched roof will likely outlive any flat roof thanks to the better-quality materials that are used in the construction of the roof.
