Converting a flat roof to a pitched metal roof – the key considerations
Are you thinking about converting from a flat roof to a pitched one? Read our blog to learn more about using metal roof tiles for a pitched roof conversion.
Flat roofs are often chosen as a low-cost roof option but can end up being expensive to maintain over the years, and in many cases needing replacing much sooner than a pitched roof. Flat roofs are more likely to leak and cause damage due to a number of reasons, mostly commonly cited as bad maintenance or poor fitting.
Due to this, many people consider converting a flat roof to a pitched roof which are better for water drainage.
Metal roof tiles are becoming increasingly popular as they come with several benefits, the most obvious being that they are lightweight and easier to install.
Here are the key considerations if you are thinking about converting a flat roof to a pitched metal roof.
If you are not replacing the roof with the exact style and pitch of the current one, you will most likely need to apply for planning permission to do so. This is the case when converting a flat roof to a pitched roof. Although, a low pitched roof will be much easier to get planning permission for if the current roof is flat, compared with a higher pitched roof.
For more about the rules on planning permission and roofing, take a look at the government’s planning portal.
How durable will it be?
Traditionally, concrete roof tiles have been thought of as the go-to durable roof tile choice. However, the latest metal roof tiles have a come a long way with steel in particular, known for its durability.
By choosing a low pitch roof over a flat roof, inevitably, the roof will be more durable as rain water will be able to flow away more easily. They also reduce the overall weight being put on the building’s structure. Flats roofs on the other hand need regular maintenance to check for holes and remove debris build up which can lead to leaks and damage.
You should keep in mind that low pitch roofs will still require care as some of the main problems of flat roofs can persist if not maintained. Checking for debris should be done regularly, particularly in the winter months. By using a non-porous, lightweight tile such as steel, durability will be higher.
Managing the installation
By choosing a lightweight metal roof, installation is usually simpler, quicker and more cost effective. It’s easier for contractors to manoeuvre with lightweight metal tiles whilst working on a project.
Tiles come in panels rather than individually, making them significantly quicker to install, compared to traditional concrete or slate tile types.
The practicality of lightweight metal roof tiles makes installation easier as long as you choose a good contractor. Projects are usually completed faster – a benefit everyone wants.
Insulating a pitched metal roof
Insulation is a key consideration for many home owners as they want to lower their consumption of energy resulting in decreased costs and less impact on the environment, whilst staying warm in their home.
Roofs can be ventilated but also need the ability to let moisture escape. This can sometimes become a tricky balancing act if the roof is in a small space.
An option that is used for many low pitches is spray polyurethane foam, which takes up less space than traditional types of insulation and can be more breathable.
