If you’ve noticed your utility bills going up, a possibility could be that your insulation is poor which means heat is escaping from your home causing the bill to go up. Insulation is an important part of your home because it helps to protect it so it’s important to check on it to make sure it’s working effectively. Caulking helps to protect your home from leaks and also helps to keep heat in your home. It’s important to check your caulking to see if it’s cracked so that you can fix it right away before any damage occurs. Maintaining your caulking and insulation helps to increase the lifetime of your roof.
