Often widely used in residential and commercial buildings, the flat roofing system is known for its strength and durability, among other benefits. However, flat roofs tend to be more prone to leaks and repair than pitched roofs.
These damages mainly occur because water does not roll off flat roofs like pitched roofs. Due to this phenomenon, there has been an increased need to replace flat roofs occasionally.
Here are some flat roof replacement options you can consider to transform your old roof into a more durable option.
Single-Ply Membrane Roofing
The single-ply membrane roofing method is one of the contemporary roofing technologies that you can use as a roof replacement option. The roofing method uses sheets of thermostat or thermoplastic membrane to create a single layer over a roof structure. The types of compounds used in this type of roofing system include the following:
- Ethylene propylene diene monomer (EPDM): EPDM is a type of durable synthetic rubber. The compound comprises propylene and ethylene derived from natural gas and oil. Roofing systems with EPDM are typically long-lasting and may last 10-25 years. Synthetic rubber is usually lightweight and relatively simple to install. Furthermore, the material is flexible, elastic, and can withstand high temperatures. Since the material is usually available in large rolls, the roofing system is ideal for commercial buildings like learning institutions, warehouses, shopping centers, and office buildings.
- Thermoplastic Polyolefin (TPO): The TPO membrane roofing features a single layer of synthetic thermoplastic material made from recycled rubber. The roofing system is usually sold in rolls held together by seams. The TPO roofing membranes are mostly applicable in large commercial buildings like recreational centers, sports facilities, restaurants, and administrative buildings.
- Polymerized Vinyl Chloride (PVC) or Polyvinyl Chloride: The PVC roofing material is a synthetic thermoplastic material resistant to fire, moisture, and wind. PVC is suitable mainly for residential and smaller commercial buildings.
The EPDM membrane is the most commonly used among the three single-ply membrane roofing systems. Although these systems were initially used for commercial buildings, they have also been adapted to residential homes.
Built-up Roof (BUR) Replacement
The Built-Up Roof (BUR) is one of the oldest roofing systems. The roofs are made of asphalt or hot tar and gravel and are constructed with three or more layers of ply sheets. The ply sheets are alternated between layers of hot tar.
Afterward, the layers are ballasted with a layer of smooth river stone or gravel to create durability and stability. Due to the many layers, the resultant roof is usually very heavy.
If you are considering replacing a different kind of roof with a BUR roofing system, you may need to install additional support for your roof.
Modified Bitumen Roof Replacement
The Modified Bitumen roofing was created as a replacement or improved version for the built-up roofing system. The system uses the BUR technology but also reinforces polymers to enhance protection and extend the roof’s lifespan. The installation methods for this type of roof include the following:
- Cold-applied
- Hot-applied
- Torch-applied
- Self-adhered
It is crucial to involve a certified roofing contractor to replace your roof with the modified bitumen roof system since installation poses possible dangers. However, even with its potential installation dangers, the modified bitumen roofing system is easy to install.
Metal Flat Roofing
You can also replace your flat roof with metal materials like aluminum. The metal materials are durable and can last up to 35 years if subjected to favorable conditions.
The most significant advantage of using metal material for roofing is that it is reflective and keeps energy costs down.
