What You May Not Know About Flat Roofs

Leaking roof insurance claim

Roofing a building is an enormous undertaking, with safety, weather, and cost all making an impact. There are many different roofing options, from pitched to flat roof types. Because flat roofs are less expensive than pitched roofs, they are the roof of choice for many commercial roofing companies. Of course, there are many different flat roof types, each with their own advantages and disadvantages. Here are the most common flat roof options used in commercial construction today.

Single-ply roofs are the most popular flat roof option. Single-ply roofing is the application of one layer of a waterproof membrane or surface. Different materials used in single-ply roofing will have varying degrees of durability and cost effectiveness. Single-ply roofing is installed by adhering it to the insulation or screwing it into the roof deck. To minimize leaking, home and business owners should hire roofing companies with experience in installing flat roofs.

Built-up roofs are made by layering tar paper, gravel, and asphalt to create a roof. To increase durability, more layers can be added at a later point, helping delay re-roofing. Built-up roofs are considered outdated for commercial buildings, but their low cost helps them remain a popular option for residences.

Spray-on roofs are the easiest of flat roof types to apply. First, foam insulation is sprayed on the roof deck. A layer of crushed stone or sand is added, then a roof coating is sprayed on top to seal the roof. Roof coatings can also be added to single-ply roofs to extend the life of the roof anywhere from 10 to 15 years.

Installing a new roof is a great way to keep a house or commercial building safe and in good condition. Be sure to talk to your contractor to find out what type of flat roof is best for your building.
