It is important to know that even the best roof in the world, with shingles of the highest quality – cannot alone defend your home. Ensuring the longevity of your roof starts with understanding that your roof is a part of a system – and if part of that system fails – your whole roof fails.
The system that works? insulation, ventilation, and protection.
The purpose of insulation is to slow the rate of heat transfer (can be in a cold or warm climate). If your home is well insulated, you’ll know. Your electricity bill will show you. The more your home is insulated, the less cold (or warm) air you will be losing due to normal air flow and the less gas/electricity you will need to warm your home.
The U.S. Department of Energy has recommended attic insulation R-Values that vary based on where you live. It is also estimated based on these values that 90% of homes in the United States alone are under insulated. That’s startling when you consider how much most homeowners spend on their energy bills annually.
In addition to insulation, ventilation can prevent roof jeopardizing issues like metal rust on nailheads, wood rot, sagging of the roof deck, and mold. These two plus the outer protection of your roof (i.e. ice and water shield and shingles), help to ensure your roof is protecting your home. This roofing system is key to keeping leaks at bay, your electricity bill low, and your roof well maintained.
If you feel that you are losing a significant amount of thermal-energy, make sure you check your electricity bill before winter hits. And of course, trust a professional to show you your best option for the minimal amount of heat loss. Trust Bone Dry!
