What are the benefits of installing a ballasted roof? Contrary to built-up roofing, this type of roof can be installed quickly and easily. It is also cheaper to install and easy to remove. In addition, this type of roof is energy-efficient. So, why choose a ballasted roof? We’ll examine these benefits below. Choosing the right ballasted roof for your home is an important decision that you will want to make.

Ballasted Roof

Unlike built-up roofs

Built-up roofs, also known as gravel or tar and gravel roofs, have several layers and are used for flat or low sloped roofs. They are characterized by their smooth finish, and manufacturers often use fibreglass or organic mats as reinforcing fabric. They are often used on industrial buildings and structures. This type of roof is not environmentally friendly, but it is a durable option for many buildings.

Stone-ballasted roof systems first appeared in the early 1970s. The two systems are similar but are quite different. The former uses a thin layer of crushed stone or pea gravel that is larger than a quarter-inch and embedded into the asphalt topcoat. The latter system uses a heavy, smooth surface layer to help keep the roofing in place and resist wind. Ballasted roof systems also feature a patented system of reversible roofing, which is a good feature for buildings with a sloped roof.

In contrast, built-up roofing has little maintenance. When a leak occurs, roofers must dig up the gravel to inspect the tar layer, which can take several feet. This is more time-consuming and more expensive than installing a ballasted roof system. Also, bitumen used in built-up roof systems is typically hot and liquefies during installation, making repairs more difficult and costly.

In addition to their low warranty claims, ballasted EPDM roofs are easy to install. Ballasted roof systems are also the fastest to install and have the lowest lifecycle cost of any type of roofing system. Ballasted roofs are also highly resistant to fire and hail. However, they should not be used for tall buildings and hurricane-prone areas. They may become flying debris during a storm. So, when evaluating a ballasted roof, do your homework and look for references before making a decision.

Another difference between built-up and ballasted roofs is their waterproofing materials. Built-up roof systems are fully waterproof, and therefore require no glue or heat welding. However, ballasted roofs require a waterproof membrane, usually made of PVC, EPDM, or TPO. The lifespan of a built-up roof system is about five years for each layer. Ballasted roofs, on the other hand, can last as long as 30 years.

Cheaper to install

While installing a ballasted roof system may cost more than an asphalt shingle roof, this option is quicker and easier to install. Ballasted roofs are typically made of large sheets of waterproofing membrane that can be installed quickly and safely in any weather conditions. In addition, this type of roofing system is extremely durable, and repair work is usually easier than with a single-ply roof. The stone or concrete pavers on a ballasted roof protect the waterproofing layer from ultraviolet rays and damage caused by foot traffic and other elements. Ballasted roof membranes are recyclable once they reach the end of their lifespan.

When compared to EPDM roof systems, ballasted roofs are the most cost-effective for a residential building. They are the least expensive per square foot, but are not ideal for tall buildings or hurricane-prone areas. In addition, ballasted roofs may not be suitable for tall buildings or areas prone to hurricanes because they can become flying debris during a storm. Despite the cost differences, these pros and cons make it worth looking into installing a ballasted roof.

A ballasted roof assembly is a method of roofing in which the insulation is laid loosely on top of an EPDM roof membrane. Each sheet is secured together with seam tape. Typically, a ballasted roof is cheaper to install than an EPDM roof system, but it does require a structural upgrade to meet local building codes. In addition to being cheaper to install, ballasted roof systems also have improved fire and weather resistance. However, the main downside of this method is that it is more difficult to detect leaks in the roofing system because it has so much ballast, and it is harder to detect wind scour.

In comparison to mechanically-fastened roofing, ballasted roof systems require less time and labor. A ballasted roof is also cheaper to repair. Because it does not require fasteners, ballasted roof systems are less expensive to install than mechanically-fastened ones. Ballasted roofs are more durable and are easier to maintain. Ballasted roofs also require less time for the contractor. The cost savings are worth the extra time and money that ballasted roof systems offer.

Easy to remove

A ballasted roof is a great option for homeowners who want to avoid the hassle of cleaning up large quantities of rock debris on their roof. This type of roof uses heavy stone to provide a solid weight barrier over a roof membrane. Unlike a flat roof, a ballasted roof can be easily removed without the need to remove the entire roof. In most cases, the job will only require one day of work. Fortunately, it can be done quite easily and safely with the help of a professional.

A ballasted roof is easy to install, but its maintenance is guaranteed to cause a large repair bill. Stone is often stepped on, causing holes to form in the membrane. Ultimately, this can make a roof leak investigation a nightmare. The ballast also helps hold dirt in place between the stones. When the stones are removed, you can see the membrane better than if it were not covered with stone. This video demonstrates how a ballasted roof can cause significant damage.

Another popular option is the use of a truck-mounted vacuum to remove the ballast. These vacuums are large enough to remove a large amount of stone, but they are also fast and easy to use. One crew member will guide the vacuum attachment over the roof and deposit the stone in a storage bin on the truck. The next step is to take the ballast off of the roof, which can cause a substantial amount of damage to the roof membrane.

Another advantage of a ballasted roof is the ease of installation and removal. This type of roof is great for large rooftops because it is fast and easy to install. The stone or pavers act as ballast to protect the waterproofing layer from weather. Another benefit of a ballasted roof is that it can be recycled. An executive at Carlisle Syntec studied ballasted roofing systems for three years. The results are astounding.


An energy-efficient ballasted roof system offers similar benefits as conventional cool roofs without the high installation costs. These roofs reduce thermal transfer from the inside to the outside of the building, delay the peak temperature and reduce evaporative cooling, and are recognized by most green building guidelines and ENERGY STAR. Listed below are some of the advantages of this type of roof. Read on to learn more about its pros and cons.

A ballasted roof is durable, long-lasting and easy to install. Ballasted roofs are also an excellent alternative to white reflective roofs. They offer the same energy benefits as these roofs without the condensation issues and heating cost penalty. Ballasted roofs can be combined with a vegetated roof garden to maximize the benefits of both. The plants will provide an attractive, livable space and protect the roofing membrane from wear and tear.

Ballasted roofs can be fast to install and complement the structure of the building, reducing the labor costs. Additionally, they are easy to remove and recycle due to their loose-lay construction. In addition, ballasted roofs can be recycled and are as good as ENERGY STAR-certified reflective roofs. This makes them an excellent option for any building. So go ahead and make your home energy-efficient by switching to a ballasted roof today.

One of the greatest advantages of a ballasted roof is its ability to absorb rainwater. They can hold up to 70 percent of 24 hours’ rain. This can provide significant relief to city sewer systems. In addition, they can reduce the need for expensive collection basins on the roof. They can even help developers earn points by installing LEED-certified roofs. With all of these benefits, it’s no wonder more people are choosing to switch to this type of roof.

Another benefit of a ballasted roof is its coolness. Ballasted roofs are cool, and they are also ANSI-accredited. The American National Standards Institute also has a standard called RP-4 that provides guidelines for the installation of cool roofs. These guidelines are reliable over the past 20 years. Moreover, the cost of installing a ballasted roof is minimal. This type of roofing system also features the lowest lifecycle costs.
