There are many different types of roofing in the Dallas, TX, area. As you try to pick out a material, it’s important to consider the type of roof you currently have (or the one you are expecting if you are getting a new roof). We have compiled the commonly asked questions to help you learn more about flat roofs.
Question: What Is a Flat Roof?
Answer: A flat roof, is one that is almost completely level. Usually anything with up to 10 degrees of pitch, (which is a term that describes the slope of a roof), is considered flat. The most common materials used for this kind of roofing system include:
- Modified Bitumen is a single-ply rolled roof that may be a peel-and-stick or torch-down system.
- Ethylene propylene diene monomer, more commonly referred to as a rubber membrane, is a durable, rubber material that is often glued down and anchored with fasteners or stabilized with stone.
- Built-up roof is made from hot tar and gravel and sometimes fiberglass membranes.
These are just a few examples of what a flat roof may be.
Q: What Type of Maintenance Is Needed?
A: Like with any kind of roof, there is certain maintenance that will need to be done if you want to avoid a roof removal and replacement. Most flat roofing systems need to have leaves, twigs, dirt and other debris removed from the surface on a regular basis as well as regular inspections of seams and vulnerable spots.
Q: Can a Flat Roof Be Recovered Rather Than Replaced?
A: Recovering is also known as using a material to tarp over your existing roof. Depending on the state of your roof, it may be a good idea to consider this option. However, if you did not perform regular roof maintenance, you may not be able to recover your roof. This is because a poorly maintained flat roof may retain moisture, which can affect the system even if it is recovered. Another reason you may not be able to go with this project is because your system may already have too many layers. Most building codes require that a roof is made up of no more than two different layers.
