A Roofing Company in North Liberty Explains the 5 Steps and Benefits of Building a Ballasted Roof — Our roofing company in North Liberty knows the world of roofing is huge and diverse, with an array of options each offering its unique advantages. Since the 1970s, one roofing system that has gained popularity is the ballasted roof.

While similar in some ways to built-up roofs, ballasted roofs have distinct features that set them apart. In this blog post, Robison, one of the top roofing companies in North Liberty, will delve into the specifics of ballasted roofs, exploring how they’re constructed, their unique characteristics, and the benefits they offer. Whether you’re a roofing contractor in North Liberty or a homeowner considering your options, this insightful guide will shed light on why ballasted roofs might be the right choice for you.

Ballasted roofs, at least in their stone form, have been popular for a while now (since the 1970s). They are comparable to built-up roofs but differ significantly in a few key ways. One way that stands out is the use of much larger stones (1 inch in diameter at least), which are applied in such a way that the “ballast” is essentially the only thing holding the components in place.

Building a Ballasted Roof

These are “loose-laid” roof types. This implies that the contractor can assemble everything without having to fasten any of the parts to the roof deck or to one another.

This is made feasible by the ballast being positioned above the membrane. This stabilizes the parts by pressing them under weight. The waterproofing layer is affixed to the parapet and specified places of penetration at the same time.

Our Roofing Company in North Liberty Lists the 5 Key Steps in Building a Ballasted Roof

  1. Preparation: Before the actual installation begins, the roof deck needs to be thoroughly cleaned and prepared. This ensures that the waterproofing layer can be laid smoothly.
  2. Laying the Waterproofing Layer: The chosen waterproofing membrane is spread across the roof deck. It’s important to ensure it covers the entire surface area and reaches the edges for complete protection.
  3. Securing the Membrane: Although the majority of the membrane is held down by the weight of the ballast, it’s mechanically attached to the parapet and certain penetration points for added security.
  4. Adding the Ballast: Large stones or concrete pavers are evenly distributed over the membrane. These act as the ‘ballast’ that gives this type of roofing its name and holds everything in place.
  5. Final Inspection: Once the ballast is laid, a final inspection is conducted to confirm everything is secure and properly installed.

A Roofing Company in North Liberty: The Value of Ballasted Roofs

Ballasted roofs bring a host of advantages to the table, making them an appealing option for many building owners and contractors. Their cost-effectiveness is a primary selling point, with the lack of screws and glue making for a quicker, more affordable installation process.

This type of roofing is also highly durable. The ballast protects the waterproofing layer from a variety of potential threats including UV rays, foot traffic, and hail. This means less maintenance and repair work in the long run, saving additional time and money.

Another notable advantage is the environmental friendliness of ballasted roofs. Since the membrane doesn’t contain any adhesives, it can be recycled once the roof has reached the end of its lifespan. Doing this reduces environmental impact, according to roofing companies in North Liberty.

A Roofing Company in North Liberty: What Benefits Can a Ballasted Roof Offer?

The cost of a ballasted roof is among its main benefits. A ballasted roof takes less time and money to build because it doesn’t require the screws and glue that other roofing systems do.

A ballasted roof also provides the roofing contractor in North Liberty with several other benefits, aside from labor and time savings.

For starters, since these roof systems can be quickly installed, there will be less likelihood of delays. In most situations, the building schedule can go as planned. Second, roofing teams are able to do their work quickly and in nearly any weather condition are still able to install enormous sheets of membrane.
