09 Aug Everything About Single-Ply Roofing Systems
Single-ply roofing systems are an attractive and affordable option for many homeowners. These roofing systems offer various benefits that make them the perfect choice for some, but there is much more to know about them before you choose this type of coverage. This article will explain everything you need to know about single-ply roofing systems.
What is a single-ply roof?
A single-ply roof comprises one layer of panes, which range in thickness from 0.6 inches to 2 inches. These roofs generally do not have a base sheet installed underneath, but some manufacturers will install a so-called “ballasted” system, which means that some gravel is placed below the plywood sheets to help with ventilation and drainage. The term “ballasted” should not be confused with ballasted single-ply roofing products, which are a type of single-ply roofing.
How is a single-ply roof different from asphalt shingles?
When people think of a “low profile” roofing system, they think of a single-ply system. However, there are many other types of systems that fall under this definition. An example of a non-single-ply low-profile roof is an asphalt shingle with an additional layer underneath the plywood to help provide additional support and ensure the roof’s structural integrity.
What are the different types of Single-Ply Roofs?
A few types of single-ply roofing systems can be used in residential construction, depending on what you need. One of the most popular is EPDM, also known as Ethylene Propylene Diene Monomer or rubber. Rubber is a synthetic material that can be used on different roofs by mixing it with materials such as fiberglass and asphalt. As a result, it can be used to repair old roofs, but they are also great for installing new roofs.
EPDM will typically be white in color, so they are often mistaken for asphalt or fiberglass roofs. However, EPDM can be used with asphalt shingles, metal roofing or even slate or tile. EPDM does not create as good of an air barrier as some other single-ply roofing systems, but it has been proven to last for more than 30 years before needing to be replaced. It is also a very cost-effective roofing material to use.
Which roofing system is the best for my home?
Some homeowners want to know if they should choose a single-ply or an asphalt shingle roof to help cover their home and provide a more aesthetically appealing appearance. This decision depends on your personal needs and preferences. If you want the look of an all-wood roof, but you want to save money, go with a single-ply roof. If you want the most affordable option but are less concerned with the appearance, asphalt shingles might be your best bet.
What is the difference between the underlayment and a ballast?
A ballast is a gravel or sand used underneath single-ply wood roofing sheets to provide additional weight and support for the plywood panels. It is important that you install ballast and underlayment as per the manufacturer’s specifications. Underlayment is a waterproof and airtight material that generally acts as a vapor barrier and helps protect the plywood sheets.
What Can Different Types of Single Ply Roofing Systems Do?
Single-ply roofing systems can be used for a wide variety of different reasons. Whether it is to add strength and durability or add an attractive element to your home, many other options are available. Here is a brief description of some of the most popular choices.
Flat Roofing Systems
One of the most common roofs today is constructed using a single layer of asphalt or other synthetic material. Asphalt flat roofing systems are typically very easy to install and relatively inexpensive to maintain since it is such a low maintenance system. However, these roofs can be prone to leaks because they have no porosity, which means there are no air pockets or voids between each roofing tile.
As a result, water can easily penetrate the system, which will eventually cause damage to the roof structure. Because of these issues, it is recommended that you install an extra layer of protection on top of your flat roofing system if you live in an area that experiences heavy rain or snow. This additional layer will prevent leaks during harsh weather conditions.
Gutter Systems
A gutter system is installed on top of your roof to serve as a means of directing water away from the underside of your home. Asphalt gutter systems are an excellent choice if you would like to have a flat area on top of your roof. However, you should make sure that the rest of the roofing system is designed specifically for this purpose. If not, it will be tough to create a flat surface and will limit airflow through your home.
These systems are relatively simple to install and generally require no extra maintenance. However, they are not an ideal choice for areas that receive a lot of rain or snowfall because they may not support the weight of the snow. This could result in leaks that will damage your roof and the interior of your home.
Eave Systems
An eave system is simply a single-ply roofing system that has been installed along the edge of your roof. They can be installed from the ground or even from the roof and will offer protection for your home in some different ways. Eave systems are a popular choice for new roofs because they will add a finished look to any home that you are building.
Roof Pitch
Asphalt roofing systems can also be used to create different degrees of pitch within your roof. This option can be used to create a unique roof appearance, depending on the type of system you choose.
Different degrees of pitch can be created by using a large number of overlapping tiles that are installed in a criss-cross pattern. This technique is known as “paving” and is often used to create a flat surface where there was previously a steep incline.
