The Roof Installation Process – Step by Step
1. Inspection & Planning
Before any work begins, a roofing contractor will inspect your roof’s condition. This includes checking for:
- Roof deck repair needs (the base layer under shingles)
- Old or damaged flashing (metal strips that prevent leaks)
- Proper ventilation (crucial for preventing mold and extending roof life)
Proper ventilation is a key part of any new roof installation, and our guide explains best practices for optimal airflow.
2. Removing the Old Roof (If Needed)
If you’re replacing an existing roof, the old shingles must be torn off first. This step ensures a clean surface for the new materials.
3. Installing Starter Shingles & Underlayment
- Starter shingles go on first to prevent wind uplift.
- A waterproof underlayment is added to protect against leaks.
4. Flashing Installation
Flashing is placed around chimneys, vents, and skylights to direct water away from weak spots.
5. Shingle or Material Installation
This is where your chosen roofing material (asphalt shingles, metal, synthetic slate, or solar shingles) is installed.
6. Final Inspection & Cleanup
A good roofing company will inspect their work and clean up debris.
Roof installation is a process that varies depending on the roofing material chosen, and it’s essential to understand the factors before deciding. You might want to check out the different roof inspection services that can ensure the job is done right.
How Long Does Roof Installation Take?
The timeline depends on:
- Roof size (1-3 days for an average home)

Most professional roof installation projects are completed within a week.
