What Is the Difference in a Flat Roof Replacement and a Sloped Roof Replacement?

What Is the Difference in a Flat Roof Replacement and a Sloped Roof Replacement?

When it’s time to replace the roof of your house, there are several important considerations you have to make. For instance, you have to consider the type and style of your roof. The two most common types of roofs in the United States are flat roofs and sloped roofs. It’s also important to understand that replacing a flat roof is not the same as replacing a sloped roof. This article will help understand the difference between a flat roof replacement and a sloped roof replacement.

What is a Flat Roof?

A flat roof is an inaccurate term because, although it is referred to as a flat roof, it is not truly flat. Even a flat roof should have a slight slope to enable rainwater to drain properly and avoid pooling of water. Traditionally, flat roofs came with a layer of tar and gravel on the upper surface. Today, flat roofs are designed with modified Bitimum, PVC, TPO, or EPDM materials. Some of these materials, especially PVC and TPO come with an Energy Star rating. This means that they can reflect most of the heat up and away from your house to keep it cool during hot months.

What is a Sloped Roof?

Also referred to as a pitched roof, a sloped roof has a well-defined slope. Normally, this slope comes in two parts, sloping away from a ridge in the center of the roof. This slope determines the steepness of the roof and it’s calculated by dividing the height of your roof by its span or horizontal depth.

The difference Between a Flat Roof and a Sloped Roof Replacement

  • Accessibility: It is easier to access a flat roof than a pitched roof. Therefore, your contractor won’t encounter many difficulties when replacing a flat roof because it is accessible and doesn’t require a lot of safety precautions. Climbing a sloped roof is a gamble because you can easily slide off. So, it takes longer to replace.
  • Risk: Your roofing contractor must use specialized equipment and additional structures to access a pitched roof or risk falling off. But these structures aren’t necessary when replacing a flat roof.
  • Cost: The cost of replacing a flat roof is lower than that of a pitched roof. Since your contractor has to set up additional safety structures to enable them to access your pitched roof, they have to factor in the extra days they have to stay at the site in their quote. This is different when you are replacing a flat roof. For more information on roof replacement, talk to J Wales Home Solutions.
