How to Replace a Commercial Roof

A commercial roof usually needs to be replaced between 15 and 50 years. This can happen because of storm damage or leaks that compromise the underlying structure. There are several ways to replace a commercial roof. These include building-up roofing, metal roofing, and green roofs. Before you get started, make sure to do some research.

Building-up roofing

Building-up roofing is an affordable flat roofing solution. Costs range from $250 per square foot to $800 per square foot. Although it provides an excellent solution for flat roofs, it also has disadvantages, including general wear and tear, and the potential for damage due to storms. For this reason, it’s important to hire a professional to install your BUR roofing system.

A built-up roof system is made up of multiple layers of roofing felt. These layers are installed on top of a base layer of asphalt or roofing felt. On top of the felt is a layer of stone, gravel, crushed slag, or other aggregates. This commercial roofing type of roof system is excellent for warm climates, and because it’s layered, it’s highly resistant to surface damage and repairs.

Building-up roofing systems are usually reinforced with fiberglass or organic materials. The roofs are then bonded together by pouring hot asphalt or cold bitumen onto them. Unlike conventional flat roofing, built-up roofing systems also offer excellent heat resistance, resulting in a noticeable reduction in heating and cooling costs.

Green roofs

Green roofs for commercial buildings have several benefits. For one thing, they help reduce water runoff. The presence of plants can also filter pollutants from the air. And, of course, they can increase the value of your property. These benefits can help your company attract researchers and increase LEED certification. If you are unsure if a green roof is the right choice for your building, you can consult with a professional to learn about the benefits of installing one.

Depending on the extent of your green roof, there are several different types of vegetation you can choose to put on your roof. Some of the most common types are succulents and grasses. These plants require low maintenance and can survive high temperatures and winds. Some are even drought-tolerant.
