How Your Roof Impacts Your Home or Business’s Energy Efficiency

How Your Roof Impacts Your Home or Business’s Energy Efficiency (And How the Right Materials Make All the Difference)

When it comes to your home or business, the roof over your head is doing more than keeping you dry—it’s playing a big role in your energy efficiency, too. From keeping you warm in the winter to staying cool in the summer, your roof can either save you money on energy bills or add unnecessary costs.

At BC Exteriors, we’ve seen firsthand how much of a difference the right materials and proper installation can make. So, let’s dive into how your roof affects energy efficiency and how products like GAF Timberline HDZ shingles, FeltBuster underlayment, and Cobra SnowCountry Advanced ventilation can help you get the most out of your roof.

 

  1. Your Roof’s Role in Energy Efficiency

Your roof is like your home’s protective shield. It regulates the flow of heat and air, which directly impacts your HVAC system. A roof that’s doing its job well will reflect heat, prevent leaks, and keep your indoor temperature consistent. But if your roof isn’t performing at its best, you’ll feel it in your wallet—higher energy bills, less comfort, and possibly even bigger repair needs down the line.

 

  1. Roofing Materials Matter

The type of shingles on your roof has a huge impact on energy efficiency. At BC Exteriors, we love using GAF Timberline HDZ shingles for their durability and performance. They’re not just good-looking—they also come with features like LayerLock Technology, which ensures they stay secure in high winds, and their reflective properties can help reduce heat absorption. That means a cooler home in the summer and less strain on your AC.

Another thing to think about? Algae growth. Over time, algae can not only stain your roof but also darken its surface, causing it to absorb more heat. GAF’s StainGuard Plus technology is specifically designed to prevent those unsightly streaks, helping your roof stay cooler and maintain its curb appeal.

 

  1. The Importance of Underlayment and Starter Strips

What’s underneath your shingles matters just as much as the shingles themselves. A quality underlayment acts as an extra layer of protection against moisture, which is critical for energy efficiency. We recommend GAF FeltBuster, a synthetic underlayment that’s tough, breathable, and far superior to traditional felt. It keeps your roof dry and prevents any leaks or water damage that could compromise insulation.

And don’t forget the starter strips! GAF Pro-Start Starter Strips create a secure seal at the edges of your roof, reducing the risk of wind-driven rain or snow sneaking under your shingles. This extra layer of defense ensures your roof stays watertight, protecting your insulation and keeping your home or business energy-efficient.

 

  1. Ventilation: The Unsung Hero of Energy Efficiency

Proper ventilation is one of the most overlooked aspects of roofing, but it’s absolutely essential. A well-ventilated roof helps regulate attic temperatures year-round. In the summer, it lets hot air escape, reducing the strain on your air conditioning. In the winter, it prevents moisture buildup that can lead to mold or rot.

We use GAF Cobra SnowCountry Advanced ridge vents because they’re designed to optimize airflow while standing up to harsh weather. They’re particularly great for Michigan homes and businesses, where extreme weather can make ventilation even more critical.

 

  1. Ridge Caps: Sealing the Deal

The edges of your roof are some of the most vulnerable areas for energy loss, leaks, and damage. That’s why finishing touches like ridge caps are so important. GAF’s Seal-a-Ridge ridge caps provide that extra layer of protection while blending seamlessly with your shingles. They help seal out water, protect against wind, and keep your roof performing efficiently, no matter the season.

 

  1. Signs Your Roof Needs an Upgrade

If your energy bills are climbing or you’re noticing drafts, uneven indoor temperatures, or even ice dams in the winter, it might be time to take a closer look at your roof. Here are a few other signs to watch for:

  • Curling or Cracked Shingles: This could mean your roof isn’t protecting your home from heat or cold as well as it should.
  • Algae Stains or Dark Streaks: A roof that absorbs too much heat isn’t energy-efficient.
  • Hot or Humid Attic in Summer: Poor ventilation could be to blame.

 

  1. Investing in Energy Efficiency

Improving your roof’s energy efficiency doesn’t necessarily mean replacing the entire thing. Repairs, upgrades, and enhancements can go a long way:

  • Replace damaged shingles with Timberline HDZ shingles for durability and better thermal regulation.
  • Install FeltBuster underlayment for added moisture protection.
  • Add Cobra SnowCountry Advanced ridge vents to improve airflow.
  • Use StainGuard Plus technology to keep your roof free from algae stains.
  • Seal edges with Pro-Start strips and Seal-a-Ridge caps for extra protection.
