When It’s Time to Replace Your Roof

Roofs are designed to protect your home, but eventually every roof needs replacement. Common signs that it’s time for a new roof include:

• Curling, missing, or cracked shingles
• Granule buildup in gutters
• Sagging or uneven rooflines
• Persistent leaks or water stains
• Roof age exceeding 20–25 years
• Visible storm or hail damage

If you’re seeing any of these signs, schedule a free roof inspection with Sisu Roofing. We’ll evaluate your roof’s condition and let you know whether replacement is necessary — honestly, every time.

Our Roof Replacement Process

Every roof replacement project follows our reliable five-step process:

1. Inspection & Estimate – We perform a thorough roof inspection, document findings with photos, and provide a transparent, no-pressure estimate.
2. Material Selection – You choose from premium materials suited to your style and budget, including asphalt shingles, standing seam metal, and flat roof systems.
3. Preparation & Tear-Off – We safely remove the old roofing materials, inspect the decking, and replace any damaged sheathing.
4. Installation – Our experienced crew installs your new roof using top-quality underlayment, flashing, ventilation, and shingles or panels for long-lasting performance.
5. Final Inspection & Cleanup – Every project ends with a complete site cleanup and final walkthrough to ensure the work meets Sisu’s high standards.
