Your roof is a long-term investment — make every layer count.
When it comes to protecting your home and everything in it, few upgrades matter more than your roof replacement. But unless you’re a contractor, it’s easy to feel like you’re in over your head when it’s time for a major project. At Handley Lumber, we help homeowners across Ontario make confident decisions — and we proudly carry GAF products, one of the most trusted names in roofing material.
If this is your first major project or you just want to stay informed, here are the most important things to know before you start.
1. Know When It’s Time to Replace — Not Just Repair
A few shingles missing after a windstorm? That might be a quick roof repair. But if you’re seeing signs like curling or cracked shingles, granule loss, or a roof leak, it’s likely time to replace the entire system. These issues tend to worsen quickly in Ontario’s climate — especially with spring rains and freeze-thaw cycles silently causing damage.
Tip: A professional inspection can confirm whether you're due for a full roof replacement or just a localized fix.
2. Your Roof Is Over 20 Years Old
Most asphalt roofs are built to last around 20–25 years. If yours is approaching or past that age, it’s time to take a closer look—even if it appears fine from the ground. Weather exposure and seasonal wear break down materials faster than most people realize.
Pro tip: Not sure how old your roof is? Check your home records or ask your real estate agent. Knowing this helps you estimate your new roof cost more accurately.
3. You See Missing, Curling, or Cracked Shingles
Shingles are your roof’s first line of defense. Cracked corners, curling edges, or missing sections all mean your roof is nearing the end of its lifespan—and your home may be vulnerable to water damage and drafts. If you're noticing these issues often, it may be time to compare your options, including shingle roof replacement cost.
4. There’s Granule Buildup in the Gutters
When asphalt shingles deteriorate, they shed granules that collect in your gutters and downspouts. This sandy debris is a key sign that your shingles are wearing out and not offering the protection they used to.
5. Your Roof Looks Saggy or Uneven
A sagging roofline may indicate trapped moisture, rotting decking, or even structural concerns. Dips or curves in the surface shouldn’t be ignored—they can lead to bigger safety issues and may increase your roof replacement cost down the line.
6. You Notice Interior Water Stains or Peeling Paint
Water damage on interior ceilings or upper walls is often tied to roofing issues. Even minor leaks can lead to insulation problems, mold, and long-term repair bills. If you're trying to decide between roof repair and replacement, look for signs inside as well as outside.
7. You’re Seeing Green (But Not in a Good Way)
Moss, mold, or algae buildup on your shingles doesn’t just affect curb appeal — it traps moisture and can accelerate wear. If you’re constantly battling green patches, it may be time to explore more durable roofing materials.
8. You’re Dealing with Higher Energy Bills
A worn roof can cause ventilation and insulation problems, which impact your heating and cooling efficiency. Rising utility bills might be a sign your attic or roofing system needs attention.
9. You’ve Had Recent Storm Damage
Ontario weather can be rough on rooftops. Hail, wind, or heavy snow can cause damage that's not always visible from the ground. An inspection after a major weather event can help you catch issues early—and get a proper roof quote before bigger problems arise.
10. Understand Your Roofing Material Options
Today’s shingles are built to last longer and look better than ever. At Handley Lumber, we offer trusted roofing materials like GAF Timberline HDZ® shingles, which offer excellent wind resistance, durability, and colour variety to match your home’s aesthetic.
Popular Roofing Materials We Carry:

11. Prep Your Home Before the Work Begins
Getting ready for a roof replacement doesn’t stop at choosing shingles. Be sure to:
- Clear your driveway for material deliveries.
- Remove outdoor items near your home.
- Notify neighbours about upcoming noise.
- Cover attic items to protect them from dust and debris.
Need help with delivery timing? We can align your material drop-off with your project schedule.
12. Ask the Right Questions — Even If You’re Not DIYing
Even if a contractor is handling your installation, it helps to ask:
- Are they certified to install GAF products?
- What’s included in the warranty?
- Will they check attic ventilation?
Not sure what to ask? Our team at Handley can help guide you through every step.
If you want the peace of mind that comes with extended warranty coverage, we can refer you to a GAF-certified installer who meets the highest standards for training, product knowledge, and installation quality.
13. Budget Realistically — and Think Long-Term
Roof replacement cost depends on your material, roof size, and labour. While cheaper options exist, choosing quality shingles upfront — like GAF’s — reduces the need for frequent repairs.
