Most people don’t think about their roof until something goes wrong. But in Ontario—where heavy snow, spring thaws, and summer storms hit hard—your roof is working overtime to protect everything inside your home. When it’s time to replace it, the process can feel overwhelming. Quotes vary widely, materials sound unfamiliar, and every contractor seems to promise something different. Many homeowners simply look at the price and assume all roof work is the same—until a leak shows up a year or two later and the repair bills start piling up.

The truth is, a long-lasting roof isn’t just about what you see on top. It’s about the layers and details underneath—the parts that rarely make it onto the brochure but make all the difference to your home’s safety and your wallet. Before you sign a contract, here are five key details to understand that will help you make smarter decisions and avoid expensive surprises.

1. Know Exactly What’s in Your Quote
Not all roofing quotes are created equal. A lower price doesn’t always mean a better deal—sometimes it simply means key steps have been left out and you’ll be hit with surprise charges later. A reliable quote should spell out:
• The exact type and brand of the roof covering (style, color, and manufacturer).
• Whether the old roof material will be removed (leaving it in place saves labor but can hide problems).
• Cleanup, transportation, and scaffolding costs.
• Details on waterproof layers, ventilation, and metal edging—often called “hidden work.”
• How damaged wood will be handled and what it will cost.

Tip: If the quote looks overly simple or vague, ask directly: “Does this include everything? Will there be any additional costs later?” A professional will explain everything clearly.

2. Materials Matter—Ontario Weather Is Tough
Ontario’s climate is no joke: strong winds, heavy snow, long winters, and then intense summer sun. Choosing the wrong materials can lead to:
• Roof coverings blowing off in high winds.
• Meltwater backing up into the attic.
• Poor ventilation causing heat buildup and mold.
• Hidden wood rot spreading because it was never replaced.

What should you look for? Stick with North America’s leading brands like GAF, BP, or Owens Corning. These materials are tested for high wind resistance (up to 130 km/h) and come with manufacturer warranties that last for decades.

3. A Roof Is More Than Just the Top Layer
What you see from the street is only part of the story. The real protection comes from the layers underneath. These hidden components often determine how many years your roof will last:

Drip Edge – A slim metal strip along the edge of the roof that directs water into the gutters. Without it, water can seep behind the gutter and rot the fascia board, leading to leaks and expensive repairs.

Underlayment – A waterproof sheet installed between the wooden deck and the outer covering. Even if the top layer is damaged in a storm, underlayment buys you time and helps keep water out. However, not every roof can or should be fully covered with underlayment—for example, very steep roofs may have safety or installation challenges. A professional contractor will inspect your roof first and explain the best approach for your home.

Flashing – Metal seals around chimneys, valleys, and other junctions. These are the areas most prone to leaks. A reliable contractor will inspect existing flashing and replace only what’s damaged or corroded—keeping what’s still in good condition to save you unnecessary costs.

Vents – Proper ventilation keeps your attic from trapping heat and moisture, which can shorten the lifespan of your roof and cause mold. Most homes use high-quality plastic vents, while some homeowners opt for metal vents for added durability or animal resistance. What matters is using quality materials and installing them correctly.

When reviewing your quote, remember to ask: “Are these details included? If not, why?” A trustworthy company will list and explain them clearly.

4. Overlaying Old Material: A Shortcut That May Cost More
Some contractors suggest: “We can leave the old material and install a new layer on top. It’s cheaper and faster.” It might sound appealing, but it’s not always the right choice. Potential problems with overlaying:
• You can’t see if the wood underneath is damaged.
• The extra weight might exceed what your home’s structure can support.
• Airflow between layers is reduced, trapping heat and moisture.
• Some home inspectors and insurance providers won’t approve a layered roof.

How we approach it: We start with a free inspection, check for damage, and evaluate your roof’s structure. Only then do we recommend whether it’s safe to add a new layer or if a full removal is the smarter investment.

5. A “25-Year Warranty” Doesn’t Always Mean 25 Years
A roof warranty usually has two parts:

1. Material warranty – provided by the manufacturer, valid only if the roof was installed according to their standards and registered properly.
2. Workmanship warranty – provided by the contractor, covering installation quality and service if problems arise.

Questions to ask:
• Will I receive the warranty in writing?
• Is it transferable if I sell my home?
• If something goes wrong, who will fix it and how quickly?

If a contractor can’t explain their warranty clearly, that’s a red flag.

Replacing a roof is not just another home improvement—it’s your home’s first line of defense against the elements. When done right, with the right layers and materials, you shouldn’t have to think about it again for decades.
