How Your Insulation Can Damage Your Roof

Missing shingles on roof due to storm damage.

When installing a roof, it’s important to make sure the material used is top-notch, and that extends to what’s beneath the shingles, all the way down to the attic insulation. However, with attic insulation, it’s not just about the quality of the material, but the accuracy of the installation as well.

If your attic insulation was placed incorrectly, meaning it wasn’t installed in the right spots, or there is too much or too little, your roof and your home could suffer from the oversight.

It Means Discomfort and Wear and Tear on Your HVAC

Bad attic insulation can mean disaster for your heating and cooling system, but not a disaster that happens in an instant like a hurricane or fire. It takes place over the long term in the form of increased wear and tear, more out-of-pocket repair costs, and ultimately, the early failing of both systems.

When your HVAC has to run all the time to keep your home at your desired temperature, it wears out faster. And when you don’t have the right amount of insulation in the right places, this is exactly what it’s forced to do.

Not only will you constantly be looking for a blanket to warm you up or turning on a fan to help keep you cool, you’ll have the discomfort of paying too many HVAC repair bills too.

It Means Higher Energy Bills

No one wants to pay more than they have to for their heating and cooling costs, but with inadequate attic insulation, that’s probably what you’ll do. When your air conditioner is working twice as hard in the summer and your furnace is working twice as hard in the winter, your bills will reflect that!

It Means Rot and Roof Damage

Inadequate ventilation of an attic space prevents any moisture that may be present from being removed. The hot/cold cycles of the days/nights as well as the seasonal temperature changes can cause moisture to condense on the wooden members of the roof. Without the proper ventilation, this collected moisture cannot dry out and will eventually cause mold and rot in the roof structure.

And Speaking of Mold

If attic insulation is blocking vents, it means there isn’t enough airflow to facilitate moisture evaporation. This can lead to mold growth, which, over time, can contribute to health problems and cause decay in the roof’s structure.

Make a habit of routinely inspecting your attic and roof throughout the year. It might make sense to take a look as the seasons change to ensure you aren’t facing any potential issues. If something doesn’t seem right, it would probably be a good idea to get your roof inspected by a professional.
