Built-up roofing is currently the most popular option used for low-slope roofs. The style is composed of several layers of bitumen and then finished with an aggregate layer or coating. Recent materials in the field incorporate rigid insulation layers. The layers used are known as ply sheets and are commonly reinforced using fiberglass mats or organic mats, depending on their use. In terms of size, these ply sheets are commonly 36-inches wide, which is standard size.
Types of Built-Up Roofing
There are currently several types of built-up roofing for use. Some are smooth asphalt and ballasted asphalt. The bitumen material commonly found in these systems are made of asphalt, coal tar, or cold-applied adhesive. The surface and its materials generally vary depending on project and budget. Usually, ballasted asphalt is used more regularly because it offers an excellent finish and the material is quite fire retardant.
On the other hand, Cold Built-Up roofing does not require hot asphalt during the application process. It can instead be sprayed or applied using a squeegee. There are no toxic fumes during application, and it is even considered better for the environment and sensitive projects.
Benefits and Drawbacks
When it comes to the advantages of using built-up roofing systems, there are numerous to consider. First off, the material and style provides excellent waterproofing, ultra-violet protection, and generally has low maintenance requirements. Furthermore, the low cost of maintenance ensures it is a smart investment all around.
On the other hand, the drawbacks are quite clear. Firstly, you have slow installation times, hazardous fumes during installation, and higher costs initially.
