Roofing Insulation: Is It Really Necessary?

One of the many overlooked aspects of a Phoenix new roof installation or Phoenix roof repair, is the importance of roof insulation. While it can be tempting to just brush it off, save the financial investment, and decide it is not really worth it, in the long run you will regret it. Not only is it a vital building block for commercial buildings, but it is very important in residential roofing as well. Here we offer some important benefits you will receive by investing in proper insulation for your roof.

Not many people are aware of this side of the coin. Proper insulation means your heating and cooling bills will be exponentially lower than if you had no insulation at all. Regardless if you have Phoenix tile roofing or Phoenix shingle roofing, your roof will always allow warm and cold air to flow in and out. The primary purpose of insulation is to slow that flow and trap the desired air inside your building. This in turn reduces the amount of work your furnace or air conditioning must do to maintain the proper temperature within your home.

Insulation is typically measured in “R values”, which a rate of measurement determining the insulation’s ability to reduce the rate of heat flow. This essentially means the higher the R value, the better your insulation works. The current recommended R measurement for a residential home is anywhere between R-20 and R-49 depending on your surrounding climate. To find out the best R-value for your home and area, contact a Phoenix roofing company near you to discuss how to best insulate your roof.


Any reliable Phoenix roofing contractor will discuss with you how insulation improves the fire safety of your home. In the event of a fire, proper insulation can help protect your roof from catching flame. Or vice versa – if your roof happened to catch on fire, the insulation would help protect the flame from quickly spreading into your attic and the rest of your home. Be certain that the insulation you choose is fire resistant. Every Phoenix roofing company should be knowledgeable on this subject and can help you choose the best insulation for protecting your home.


No matter what type of material your roof is made from, or how well the home was built, humid air will begin to be trapped under your roof due to air flow and moisture from the weather. Whether you keep your home warm or cool, the trapped humidity can easily encourage mold and mildew growth on your roof beams, attic walls, and drywall. Not only does this compromise the structural integrity of your roof, but it creates a hazardous air quality for your home that can be dangerous for both people and pets. Having the proper amount of insulation will help your roof be mold-resistant, help prevent damages, and help keep you from having a Phoenix re-roofing project on your hands.

These are just a few of the many benefits that come from having proper insulation in your roof.
