4 Ways Replacing an Old Roof Can Boost Energy Efficiency
Posted on: 22 March 2023
Replacing an old roof might seem like an unnecessary expense, but it can help prevent more serious structural damage in the future. Additionally, an old roof generally won't hold in heat or keep out the cold as effectively during colder weather, and that can mean your heating system will be forced to consume more energy to keep your home nice and warm.
Unnecessary energy consumption is bad for the environment and will increase your monthly bills, so investing in a new roof can make your home far more efficient. Here are just four reasons why.
1. Cracks and Gaps Let Heat Out
If your roof is getting on in years, it's more likely than a newer roof to have developed small cracks and other gaps. These might seem like relatively small issues, especially when water is still unable to get through, but even small gaps and cracks can let heat out of your property. Additionally, any gaps can let in cold gusts of air. Since heat rises, your roof is one of the easiest places for it to escape, so ensuring your roof is completely undamaged can make a real difference.
2. Older Materials Aren't as Effective
Even if you're replacing a roof with the same basic material that was used previously, the material you choose will often be more advanced than the one it replaces. For example, modern shingles offer higher efficiency ratings, so they tend to be much better at keeping in heat. You can also opt for a different type of roofing material that offers superior insulation in order to take efficiency even further. As such, simply changing to a different roofing material can drastically decrease the amount you'll need to spend heating your home.
3. Old Roofs Are More Likely to Let in Moisture
Everyone knows a leaky roof is bad, but most people don't realize that even a small amount of moisture can have a big impact. Over the years, moisture can penetrate older roofs, which can cause the felt underlay used in many roofs to deteriorate. Leaks can also cause loft insulation to compress or clump. Both issues will significantly impact your home's ability to keep in the heat, but a new roof can help keep that moisture out.
4. Old Roofs Often Suffer From Pooling Water
Older roofs often suffer from sagging, which means water will be allowed to pool across certain spots. This increases the chances of a leak, but standing water can be a problem even when moisture doesn't get through the roof since it will create cold spots, especially when that water is allowed to freeze. Those cold spots will make the air in your attic space cooler, which will in turn force your heating system to work harder.
