What You Should Know Before Changing Your Roof

 

Here’s a clear, practical guide on what you should know before changing your roof — whether you’re doing it for wear and tear, leaks, or a visual upgrade:

1. Assess the Condition of Your Current Roof

  • Inspect for missing shingles, leaks, sagging areas, or granule loss.

  • Check the attic for water stains or daylight coming through.

  • A professional roofing inspection can confirm if you need a repair or full replacement.

2. Choose the Right Roofing Material

Different materials affect cost, lifespan, and appearance.
Here are common options:

  • Asphalt Shingles: Affordable and widely used; lifespan ~20–25 years.

  • Metal Roofing: Durable, energy-efficient, and long-lasting (40–70 years).

  • Clay or Concrete Tiles: Elegant look, excellent longevity, but heavier.

  • Slate Roofing: Premium option with 75–100+ year lifespan.

  • Synthetic or Composite Materials: Mimic traditional looks with less maintenance.

3. Understand the Costs

Roof replacement costs depend on:

  • Material type

  • Roof size and slope

  • Labour and disposal fees

  • Underlayment, flashing, and ventilation upgrades

 4. Hire a Licensed, Insured Contractor

  • Check credentials, reviews, and warranties.

  • Ask about workers’ compensation and liability insurance.

  • Ensure they provide a written contract and timeline.

5. Timing and Weather Matter

  • Best seasons: Spring and Fall (mild temperatures, fewer delays).

  • Avoid replacements during heavy rain or snow seasons, as installation quality can suffer.

6. Don’t Ignore Roof Ventilation

Proper ventilation prevents:

  • Heat buildup in the attic

  • Ice dams in winter

  • Premature shingle damage

Your contractor should inspect and possibly update vents or insulation.

9. Consider Energy Efficiency

Some materials (like cool roofing or metal) reflect more sunlight, lowering energy costs.
You may also qualify for energy efficiency rebates.
