When you live in a cold climate like Manchester, you already know that keeping your house warm can be difficult (and costly), but what if there was something you could do that would help boost your home’s efficiency, lower your monthly energy bills, and also help protect your Manchester roofing? Having proper insulation levels in your attic can actually do all of these things.
Determining Insulation Levels
One of the most difficult things for many homeowners is simply not knowing how much insulation is appropriate in the attic. If you don’t have enough, it could be contributing to energy bills that are as much as 10 to 50 percent higher—but how do you know if that is the case for your home? The Department of Energy actually has recommendations for homeowners based on where you live. In the Manchester area, they recommend having insulation with an R-value (a measure of its ability to resist heat flow) between R-38 and R-60. You can find the full chart and other insulation tips at the Department of Energy website.
Once you know what you need, check your attic to find out how much you currently have. You may need to call a professional roofing contractor in Manchester to help you identify what is there. With that information you can figure out how much more you need to add to make your home as energy efficient as possible. You can add either loose fill or batts (rolls), and the right one often depends on the layout of your attic, the R-value required, and the existing insulation you have. These two types come in several material choices, including:
- Mineral wool
How it Protects Your Roofing
With inadequate insulation the warm air from your home rises and gets into the attic, where it creates a warm, moisture-rich environment, the perfect ingredients to grow mold and mildew. Over time this mold can eat away at the roofing support structure, including the wooden beams that are holding that roof up. Excess moisture can also eat away at roofing shingles over time, causing them to weaken and requiring roof replacement sooner than should be necessary. The excess humidity in the attic can also rust nails and other metal fasteners, leading to a less secure roof over time.
Whenever you add insulation you want to make sure that you don’t block the proper flow of air or create ventilation problems for the roofing, so it’s best to hire a professional Manchester roofing contractor to help so you know it will be done right.
