Everything You Need to Know About Flat Roofs: Types, Cost, and More

Flat roofs are a popular choice for both commercial and residential buildings. They offer a sleek, modern look and can be more affordable than other types of roofs. If you're considering getting a new roof or replacing your existing one, you might be wondering if a flat roof is the right choice for you. In this blog post, we'll explore the different types of flat roofs, their costs, and other important things you need to know.

Types of Flat Roofs

There are three main types of flat roofs: built-up roofs (BUR), modified bitumen roofs (MBR), and single-ply roofs.

Built-up roofs are made of layers of asphalt and felt, with a final layer of gravel or reflective coating. They are the most common type of flat roof and can last up to 30 years. However, they are heavy and require regular maintenance.

Modified bitumen roofs are made of asphalt and a rubber modifier, which makes them more flexible than built-up roofs. They are easier to install and maintain, but may not last as long.

Single-ply roofs are made of a single layer of synthetic material, such as PVC or TPO. They are lightweight and easy to install, but may be more expensive and less durable than other types of flat roofs.

Cost of Flat Roofs

The cost of a flat roof depends on several factors, including the type of roof, the size of the roof, and the complexity of the installation. On average, a flat roof installation can cost between $5 and $10 per square foot.

Built-up roofs are typically the most expensive type of flat roof, with a cost of around $7 to $10 per square foot. Modified bitumen roofs are slightly less expensive, with a cost of around $5 to $7 per square foot. Single-ply roofs are the least expensive, with a cost of around $4 to $6 per square foot.

Other Things to Consider

When choosing a flat roof, it's important to consider factors such as insulation, drainage, and maintenance. Flat roofs can be prone to leaks and water damage, so proper insulation and drainage are crucial.

Regular maintenance is also important to ensure the longevity of your flat roof. This includes regular inspections, cleaning, and repairs as needed.

Overall, flat roofs can be a great choice for both commercial and residential buildings. They offer a sleek, modern look and can be more affordable than other types of roofs. However, it's important to choose the right type of flat roof and to ensure proper installation and maintenance to avoid water damage and other issues.
