What are the advantages of a flat roof?
Flat roofs offer numerous benefits. They are a popular choice for commercial and industrial owners and, in recent years, have seen a phenomenal growth in popularity among residential developers. In some countries, flat roofs are the solution of choice for apartment builders, as they provide additional living space for residents.
Discover all the other advantages of flat roofs below.
Multiple landscaping options for a flat roof
One of the greatest benefits of owning a flat roof is the possibility of creating an additional living area on top of it. The craze for roof terraces continues to grow, even if the technical criteria for constructing “green roofs” can present challenges for eco-contractors.
Savings on maintenance costs
In addition to landscaping possibilities, certain features allow you to make savings. For example, the cost of installing and maintaining a flat roof is often lower than that of a pitched roof. You will also save money on roofing materials. Installing solar panels also allows for substantial energy savings. Therefore, despite the balance of pros and cons, it remains more economical than a pitched roof.
What are the disadvantages of a flat roof?
Like any roof type, there are downsides. Now that we have established the benefits, we must mention the few disadvantages that come with it.
Regulations and local planning permissions
One of the main drawbacks of a flat roof is the need to check local building regulations. Indeed, this type of roof is not permitted by all local authorities. You must ensure that this is not an issue in your residential area.
Waterproofing issues
When discussing flat roofs, one cannot overlook issues related to waterproofing. This doesn’t just refer to water ingress; it also includes heat loss and the ventilation of the roof void.
Let’s start with water-related issues, as these cause the most damage to buildings. Unlike a pitched roof, a flat roof does not allow rainwater to run off as easily. For the same reason, wear and tear on gutters may appear more quickly.
Climate change
With the right coating, your flat roof can resist weather changes for many years. However, certain flat roof materials, such as concrete and gravel, can be more vulnerable to extreme temperature fluctuations.
Synthetic membranes and coatings
In terms of coverings, you have a more limited number of options for a flat roof. Aside from concrete and gravel, other materials include synthetic coatings and membranes, such as EPDM or elastomeric membranes.
Snow accumulation and clearing
Snow accumulation is another major issue for flat roofs. Even with a solid frame, it is recommended to clear the roof when accumulation reaches 50 cm. You will need to handle the snow clearing yourself or hire professionals to avoid damaging the roof.
After all, while flat roofs have various pros and cons, they are the only roofing type that offers the possibility of a rooftop garden. If you want to enjoy a green space and have the budget to modify your flat roof structure, you will greatly appreciate having a slice of nature on your roof.
