How To Prepare Your Attic For Insulation

Posted on: 1 July 2019


If your attic is lacking in insulation, adding insulation to your attic can really improve the overall energy efficiency of your home. Before you start adding insulation to your attic, you want to assess the overall condition in your attic and make necessary improvements before adding the insulation.

Check for Leaks

The first thing you need to do is check for leaks. One of the first places roof leaks are often spotted is inside your attic. Inspect your attic and look for wet insulation, mold, or rotting rafters. If you spot signs of water in your attic, you are going to want to address the leak before you install any new installation. You don't want to install new insulation only to have it ruined. You may need to bring a roofing contractor to fix your roof so that no more water will leak into your attic.

Check the Rafters

If you have an older home, you are going to want to have a structural engineer come out and check your rafters. The rafters in many older homes would now be considered undersized. A structural engineer will be able to let you know if your rafters are undersized and if you should add additional rafters to your ceiling.

An engineer or contractor can also identify if any rafters are sagging or damaged. You will want to have any damaged or sagging rafters fixed up before adding insulation to your attic.

Although you are not required to fix and upgrade your rafters, it makes sense to have a strong structure before adding insulation. Making changes to your attic after you add insulation will be more work.

Sealing Your Attic

Next, you want a contractor to identify and seal up any little gaps in your attic. Having an airtight attic will help make the new insulation you install there even more effective. Your contractor can use both caulking and expanding foam to deal with cracks and gaps, depending on the size of the space that needs to be filled.

Choose the Right Insulation

Once your attic is prepared and ready to go, it is time to install the right type of insulation. You can install blow-in insulation, batt insulation, or spray foam insulation. The type of insulation depends upon the structure and set-up of your attic. When choosing insulation, be sure to discuss the R-value with your contractor. The higher the R-value, the more insulating the material will be. Once the installation is installed in your well-sealed attic, your home will energy more stable energy bills, with less heat escaping through your attic.
