Over my 20+ years working on homes across Milton, Halton Hills, Burlington, Oakville, Mississauga, Brampton, and Guelph, I’ve learned that the roof over your head does a lot more than just keep you dry — it plays a massive role in your home’s energy efficiency.
Today, I want to share the roofing upgrades that can make a real difference in lowering your energy bills — backed by personal experience and real-world results from homeowners just like you.
One of the biggest factors in energy savings? The type of roofing material you choose.
Certain materials naturally reflect more sunlight and heat:
Story from the field:
Last summer, we re-roofed a home in Oakville using reflective metal roofing.
The homeowner called me a month later — not only was the upstairs way more comfortable, but their hydro bill dropped nearly 18% compared to the previous year.
When your roof helps keep the heat out, your air conditioner doesn’t have to work nearly as hard.
When we think about insulation, people often picture the pink stuff in the attic — but your roof system is just as important.
If your roof deck or attic isn’t properly insulated:
When we reroof in Mississauga and Burlington, I often recommend adding rigid foam insulation under the new roofing system.
It’s a small upgrade that can slash heating and cooling costs by 10–20% — and you may even qualify for local rebates.
Personal Tip: Always ask about insulation options when you’re replacing your roof.
It’s much cheaper to add it now than to retrofit it later.
Proper attic ventilation is crucial, and yet it’s often overlooked.
Here’s why it matters:
I can’t tell you how many times I’ve gone up into an attic in Guelph or Halton Hills only to find moisture damage or stifling heat because of poor ventilation.
A simple system of ridge vents and soffit vents can make a huge difference, keeping your attic close to outdoor temperature year-round.
Bonus: Good ventilation helps your roof last longer too.
Dark roofs absorb more heat — it’s just physics.
If you’re reroofing and want better energy efficiency, consider lighter shades.
One of my clients in Milton was worried a lighter roof wouldn’t look good with their brick house, but we chose a soft stone-grey metal roof.
It looked fantastic and they noticed a 20% reduction in cooling costs that first summer.
Small gaps and cracks may not seem like a big deal, but they can leak air just like they leak water.
When we replace roofs in Brampton or Oakville, we always:
A tightly sealed roof doesn’t just keep you dry — it keeps conditioned air where it belongs: inside your home.
If you’re serious about cutting energy costs, Ontario homeowners have a unique opportunity when replacing their roofs: adding solar panels.
More homeowners in Burlington and Mississauga are pairing metal roofs with solar panel installations because:
Real Story:
I had a couple in Oakville install a standing seam metal roof and solar panels in 2021.
By summer 2022, they were generating so much electricity they sold some back to the grid.
If you’re curious about combining a new roof with solar energy, ask me — I’ll connect you with reputable installers I trust.
Here’s the math:
Even modest improvements like better insulation and ventilation can cut your energy bills by 15–30%.
If you spend $3,000 a year on heating and cooling, you could save up to $900 annually — and those savings stack up every single year.

Choosing the right roofing upgrades isn’t just about protecting your home — it’s about protecting your wallet too.
