Are you thinking of adding a new roof to your home or business? If so, it is important to consider all your options including installing a flat roof. Unlike pitched roofs, which come in a variety of styles and all slope to some degree, flat roofs have no slope and can be available in built-up, single-ply and sprayed polyurethane foam designs. Here are some of the pros and cons of installing a flat roof.
Pros of Installing A Flat Roof:
Flat roofs are significantly less expensive than their pitched counterparts. Flat roofs are easier to install because they lack a dangerous pitch which makes it difficult for the installer to navigate. Flat roofs also lack the rafters and trusses that pitched roofs require making allowing for fewer materials.
Installing a flat roof gives you more usable space in the area below. Many time pitched roofs leave dead space in the attic or rooms with extreme angles. Having a flat roof eliminates this issue and can allow for more space. You also have the option of adding a rooftop deck or patio with a flat roof.
Cons of Installing a Flat Roof
All roofs require regular maintenance but due to the structure of flat roofs they may require more maintenance throughout their lifetime. Drainage is not quite as effective as pitched roofs and drains can often become clogged which can lead to leaks and damage. Flat roofs often require a waterproof seal which must be maintained regularly.
The lifespan of a flat roof can be as short as 10 years. This is due to the beating flat roofs take because they do not naturally drain.
