Importance of Insulation with Metal Roofs

[fa icon="calendar"] 02/02/2021 / by Kaylee Beattie

One of the most important components of metal roofing is proper insulation. Ensuring your roof has proper insulation can help extend its lifespan, increase its performance, and help you save money in energy costs. We’re diving into the importance of insulation with metal roofing.

What Is Roof Insulation?

Insulation is the material used to prevent the transfer of heat and, in some cases, sound. It acts as a barrier to heat loss and heat gain. For metal roofs especially, it also helps reduce the noise from precipitation hitting the roof.

Why is Insulation Important For Metal Roofs?

There are many benefits of properly insulating your metal roof. Whether it's reducing your energy costs or helping to increase your roof’s lifespan, insulation is a critical component to a high-performing roof.

Energy Savings

Proper insulation of your metal roof helps regulate temperatures inside your home, keeping your home warmer in the winter and cooler in the summer. Helping to control the internal temperatures and reduce the amount of heating and air conditioning needed to regulate those temperatures in turn helps you save money in energy costs. 

Reduces A Home’s Carbon Footprint

By decreasing the need for heating and air conditioning, you’re not only saving money — you’re also helping reduce your carbon footprint. Your home will not require as much energy or electricity expenditure, which is good for your wallet and the environment.

Noise Reduction

The sound of rain hitting a metal roof can be soothing to some, but not-so-soothing to others. Metal roofs have a long-standing myth of being noisy when it rains. However, insulation is the key factor in noise reduction of metal roofs. Insulation will absorb noise with ease, along with the other components of a roof like underlayment, decking, etc. Good insulation results in a less noisy roof when it’s raining.

Helps Prevent Ice Dams

Ice damming occurs when a ridge of ice forms at the edge of a roof and prevents melting snow from properly draining off. The water that stays backed up behind the ices dams can cause damage by leaking into your home. Insulation can help prevent ice damming from occurring because it keeps the roof cold while snow lays on top of it. Without proper insulation, the rising heat from your home can potentially melt the snow, leading to ice dams forming. 

Reduce Humidity

The cause of most home’s mold, rot, and mildew issues in an attic are typically due to moisture build-up. Ensuring your metal roof has proper insulation can help reduce humidity levels and moisture, which will help reduce the chances of any fungi build-up that would lead to mold, rot, or mildew.


Insulation is a crucial part of your metal roof and its performance. Ensuring you’ve taken the proper steps to insulate your roof well can result it better performance, lower energy costs, and increase its lifespan.
