Does Your Office Building Have a Flat Roof? 4 Types of Low-Slope Roofing Materials to Use

Need to install a new roof on your office building? The type of roof that you have will help determine what kind of materials you can use. Roofs are split between two categories: steep slope and low slope, with it being likely that your office building uses the latter. While steep slope roofs allow for materials like slate or clay tiles, these 4 roofing materials will be more fit for a flat roof with a low slope.

Metal

Metal panels are a popular roofing material since moisture will be unable to penetrate the extremely durable material. Metal is so durable that it will actually last between 40-70 years. If being eco-friendly is a concern when replacing your roof, know that metal roofing material can be made with anywhere between 25-95% recycled materials.

Built-Up Membrane

Gravel and tar are often used for built-up membranes, which is a commonly used roofing material in the US. The membrane uses bitumen, which is essentially multiple layers made with tar or asphalt, and is reinforced using roofing felt that has glass fiber in it.

The strength of built-up membranes is that provides UV protection from the sun and waterproofing. It makes the material very durable and a fine choice for a low slope roof.

Single-Ply Membrane

A single-ply membrane is a step down from a built-up membrane, since it only uses a single, thin layer to protect your roof. However, this type of membrane will be an affordable alternative to the build-up membrane. For instance, it shares many of the same benefits, such as UB protection that can decrease how much energy your building uses.

Many roofers find that the installation of a single-ply membrane roof will go much easier, helping reduce the labor involved with installing the material.

SPF (Spray Polyurethane Foam)

One roofing material that will perform really well is spray foam made out of polyurethane. The installation process involves applying two layers, starting with a layer of foam that is sprayed with a protective coating.

SPF gives your roof excellent protection from various weather conditions, and also has properties that make it fire resistant. SPF is lightweight, which makes it easy to install and maintain. You will not need to reinforce your roof due to the weight of the foam after the installation.
