Types of Flat Roof
Here are the 4 main types of flat roofing. Read and remember them or use this list as a reference when choosing the best flat roof for your project.
- Rubber membrane
Rubber membrane, also called EPDM (ethylene propylene diene monomer), is a flat roof type that is composed of rubber sheet; hence the name. It is installed using adhesive and is often installed after a layer of vapor control sheet and insulation. This makes the EPDM roofing type ideal for roofs that experience rainy seasons.
It is not ideal for warmer areas, though, since the black color of the rubber sheet absorbs more heat. This makes the building or house hotter during summer months. However, there are versions with lighter colors, which enable homeowners to install it on warmer areas. This will prevent the membrane from absorbing too much heat, which will be more efficient in keeping your house cooler during the summer months.
It costs about $4 to $6 per square foot to install EPDM roofing. That cost can get higher if there are customizations or if you are choosing a light colored rubber sheet for your project.
- Modified bitumen
Modified bitumen membrane is a type of roofing material made from asphalt sheet. But instead of the regular plasticizers, modifiers are added for durability and strength. This is installed through various procedures such as torching, cold adhesive installation and asphalt.
One of the best advantages of this type of roofing is durability and weather resistance. It is also slightly cheaper than rubber membrane and costs only about $4 to $5 per square foot. Of course, the cost can get higher depending on the specifications of your project.
The only drawback in using modified bitumen is one of its application methods is a fire hazard. Torching the membrane onto the roof is hazardous as it can cause fires. Hence, professional installation is always recommended and DIY projects should be saved for other roofing materials.
- Built-up roofing
Built-up roofing or BUR is a type of roofing that is made from tar and gravel. It was commonly used a century ago and is still popular nowadays. This roofing type is composed of multiple layers of waterproof materials alternated with hot tar. The finish is ballasted layer of river stone to ensure durability.
This is the cheapest variant of roofing option. It costs just about $2.50 to $5 per square foot to install this type of roofing, which is quite cheap compared to other options. The price may get higher if there are certain customizations on your roofing project but BUR is still considered to be the cheapest option in the market today.
This roofing option is also fire resistant. Because stone is a fire retardant, accidents like fires are not a cause of concern in this kind of roofing.
The drawback of choosing this roofing type, however, is it is too heavy. Additional support is needed if you decide to change from a certain type of lighter roofing material to built-up roof. You need to have additional joists and support posts added to your home’s frame before you can have this type of roofing. Failing to do so might result in your roof hanging low or collapsing altogether. The lifespan of your roof will also be significantly shorter if proper support is not built prior to the installation of your built-up roof.
- Single-ply one-piece membrane
Single-ply one-piece membrane roofing materials can either be EPDM, PVC (polyvinyl chloride) or TPO (thermoplastic polyolefin). These membranes can be manufactured in a single-piece, which means that the entire roof can be covered in a customized membrane that will fit the size of the roof.
The advantage of this type of roofing material is that the seams are minimized and there are no joints where water can get through. Peeling of the sheets is also not a concern since there is no area where peeling will be prone. The only area to take care of is the edges of the roof, which installers often reinforce to prevent peeling. Installation, however, can be challenging since the single-piece roofing needs to be laid into the roof without wrinkling the sheet.
It only costs about $3 to $5 per square foot to order a single-ply roofing membrane but one-piece ones can cost more due to customizations. Hence, before you decide whether this roofing type is the one for you, you should consider the additional costs that will be incurred when you decide to order a custom roofing membrane for your roof.
Choosing the right roofing type for your flat roof is important since flat roofs tend to leak. Since the water cannot easily go down gutters and drains, it can seep into the flat concrete roof and cause leakage and water damage below. Hence, before you choose the roofing type for your project, determine your best options by weighing the advantages and disadvantages of each roofing type.
Doing so will help you determine which roofing options will be most advantageous to you. The benefits should outweigh the drawbacks to be able to consider a roofing material advantageous. Thus, make it a point to take your time in determine which options you can handle the drawbacks and which ones you will find bothersome.
