When you're ready to install a new roof on your commercial building, all of the choices available can be somewhat overwhelming. Your roofing contractor may recommend that you consider built-up roofing for your project, and for good reason. If you're new to roofing fundamentals, you may not understand what this type of roof actually is nor why it's such a great option. Here are a few things you should know about built-up roofing as you make your choice.
What Exactly Is Built-Up Roofing?
Built-up roofing is aptly named. It's a roofing surface that's composed of several different roofing material layers that are applied in a specific order to build up the final roof. Usually, built-up roofing starts with a layer of bitumen.
Depending on your preference, your roofer will install either hot or cold bitumen. Hot bitumen will be applied as a liquid and spread across the roof while cold bitumen is usually sprayed. Cold bitumen is a great option when you're concerned about chemicals and fumes because it doesn't release the same types of fumes that hot bitumen will when applied.
The second layer consists of fiberglass or organic fabric sheets that are applied directly on top of the bitumen. The sheets are applied before the bitumen cures so that they adhere and form a secure bond.
Finally, you'll have to choose your surface material. Your roofer will review all of your surface layer options, and it will be up to you to decide what type of final appearance you're looking for. The goal is to balance that final appearance with your ultraviolet, climate, and hazard protection needs.
Why Consider Built-Up Roofing?
Built-up roofing is a great option for most commercial buildings. Due to the way it is constructed, it is typically very durable. It resists damage from the weather, which reduces your risk of roofing repair expenses.
Additionally, the multiple layers constructed together will help to form a seal that protects your roof from leaks as well. Built-up roofing offers greater waterproofing than some of the more vulnerable roofing materials.
The aggregate surface material also helps to provide some fire resistance, which can protect your building in the event of a fire risk.
Understanding built-up roofing is the first step to deciding if it's right for your business. Because of the multi-layer approach, these roofing materials can take longer to install, but that time investment can be worthwhile for the lifespan and durability benefits that you'll enjoy from the final product.
