5 Reasons to Have Commercial Roofing With Insulation Layers

The right components differentiates a successful roofing project from a failed one. And learning why commercial roofing with staggered insulation layers is important if you want to achieve success in the long-run.

Selecting the appropriate element for a project drastically upgrades the performance and durability of the overall commercial building.

What exactly are we talking about?

Why Commercial Roofing with Insulation Layers is Important

We are referring to the insulation you choose in your commercial roofing project. These choices affect your commercial building’s resilience and efficiency in regulating indoor temperature.

Back in 2015, the International Energy Conservation Code (IECC) raised the R-value requirements for the opaque thermal envelope in  many climate zones across the United States. Practically speaking, roofs will require two or more layers of insulation to meet the local energy code requirements.

And in 2018, IECC updated with specific installation requirements for constant roof insulation.

The benefits of commercial roofing with insulation layers include:

Prevents air intrusion

Conditioned air entering the building envelope due to pressure gradients carry moisture into the roofing system. And moisture undermines optimal performance. And thanks to insulation layers, you can minimize air intrusion by nearly 60%.

In addition, by placing limits on the flow of air and moisture through your roof system, layered roof insulation reduces and/or prevents condensation. And condensation can cause damage to the substrate and consequently shorten the roof longevity.

Better temperature regulation

The joints on multiple layers of roofing insulation offset gaps where heat can pass between adjacent boards. This approach to installing insulation decreases thermal bridging in the roof assembly.

Gathering water ponds

You can create roof slopes with tapered insulation systems, and they offer a way to improve overall energy performance of a system — or in this case, a building. By tapering added insulation layers, the slopes that you form work well for improving drainage performance.

It’s crucial because you don’t want your rainwater to remain standing on the flat roof. And stagnant water collects debris and dirt that increases the swift erosion of roofing coverings. So, by improving drainage on your roof, you lengthen the longevity of its life.

Adaptable roof assemblage

Commercial roofing with insulation layers reduce the stress placed on a single insulation layer. In addition, a commercial roofing with insulation layers distribute stress more evenly across multiple and thinner insulation layers.

In a system like this, the upper layer of insulation protects the membrane from any physical damage caused by fasteners that attach to the bottom layer of insulation to the deck of the roof.

Resistance against punctures

Roof cover boards are mostly installed to provide suitable substrates for membrane attachment as well as protect the assembly of the roof from foot and other sorts of puncture traffic. Roofs are prone to this especially if they undergo constant maintenance.

The Takeaway

Properly designed roof systems utilize high-performance polyiso insulation products is a firm foundation for sustainable commercial roofing construction and is also energy-efficient.

And commercial roofing with insulation layers can be achieved with proper installation practices. For this reason, you need a professional roofing service to help you with these commercial roofing needs.
