There are several reasons why you may be considering converting a flat garage roof to a pitched roof. Perhaps you are having issues with water leakage, or would like to convert it into a useable room, or you just prefer the look of a pitched roof.

Here are some of the considerations you are likely to have if you are thinking about converting a flat garage roof to a pitched roof.

Does the flat roof have significant damage?

If the flat roof has become damaged, it can be for a number of reasons: Poor design, construction or maintenance. Typically, flat roofs are more likely to suffer worse water damage than pitched roofs, resulting in damage to the structure due to the strain placed on the walls.

At this point, you may be wondering whether it is best to replace a damaged flat roof with a pitched roof so as to stop water damage arising in the future.

A conversion to a pitched roof may not actually cost any more than a flat roof replacement making it a viable option for many people.

New developments in building materials such as low pitch roof tiles have made such extensions an increasingly simple, cost-effective and attractive option.

Will a pitched roof last longer?

When it comes to longevity, in general, pitched roofs are thought to last longer than flat ones. However, it really depends on the workmanship of your contractors and quality of the materials for how durable your roof will be.

After particularly bad weather, it’s important to remove any debris that builds up on a roof to stop damage and weighing down of the roof.

Choosing a durable material and having a sufficient water run-off capability is key to ensuring the roof stands the test of time.

Metrotile is made from lightweight steel and weighs around one-eighth of a concrete tile. More robust, lower maintenance, longer lasting and better looking than UPVC membrane, lightweight metal tiles are a highly attractive option for converting a flat garage roof to a pitched roof.

Do you need to insulate the garage?

 Converting a garage into a family room is a popular choice for many people who require the extra space and are looking to increase the value of their home.

If you are considering a conversion, a pitched roof may be a better option than a flat one as you can more easily insulate and ventilate it.

Garages tend to be cold and have little to no insulation because a flat roof does not allow much space for insulation. A garage usually doesn’t need insulation – unless it becomes a habitable room at which point, the height of the roof will become important.

The material you choose for insulation depends on the pitch of the roof you opt for. Aim for a good balance between ventilation and insulation if you are converting your garage into a room.

Is planning permission required?

Converting a flat garage roof to a pitched roof is a relatively simple job for professional roofing contractors. However, you will likely need to apply for planning permission as it is not a like-for-like replacement.

This should be a straightforward process, especially if it is a low pitch roof. If you’re planning make more complex structural alterations, it may be best to contact the local planning authority for their advice.
