Replacing a roof can seem like a daunting task for homeowners. From the beginning inspection to the final cleanup, understanding what is involved in a roof replacement helps you prepare, reduces stress, and ensures a smoother project. Whether you’re replacing an asphalt shingle roof, tile roof, or metal roof, the process generally follows a set of steps that professional roofers adhere to for safety and quality. Xpert Xterior would like to walk you through the complete roof replacement process so you know what to expect.
Roof Inspection & Assessment
Before any work begins, a professional roofer will inspect your existing roof to determine:
• The extent of wear, damage, or leaks.
• The type of roofing materials currently in place.
• Structural integrity of the roof decking and supports.
• Local building codes or HOA requirements.
This step ensures the roofer can create an accurate estimate and develop a plan tailored to your home.
Choosing Roof Materials & Planning
Once the inspection is complete, you will select the new roofing materials. Considerations may include:
• Material type: Asphalt shingles, metal, tile, or slate.
• Color and style: Matching your home’s aesthetic.
• Durability and lifespan: Longer-lasting materials may have higher upfront costs but lower long-term maintenance.
At this stage, the contractor will also obtain any necessary permits and schedule the replacement date.
Preparing the Job Site
Before work begins, roofers will prepare your property to ensure safety and minimize damage:
• Setting up ladders, scaffolding, and safety harnesses.
• Covering landscaping, siding, and outdoor furniture with tarps.
• Protecting gutters and ensuring safe disposal for old materials.
Preparation helps prevent accidents and keeps your home and yard safe.
Removing the Old Roof
For most roof replacements, the old roofing materials must be removed:
• Shingles or tiles are stripped away.
• Flashing, underlayment, and sometimes decking are inspected and repaired if needed.
• Roof debris is collected and removed for disposal.
Some roofs may allow an overlay, but tear-off is often recommended for aging or damaged roofs to ensure proper installation.
Inspecting & Repairing the Roof Deck
Once the old roof is removed, the roof deck or the wooden surface beneath the shingles is inspected for:
• Rot or water damage.
• Loose or damaged boards.
• Structural weaknesses.
Any compromised areas are repaired or replaced to create a strong, even foundation for the new roof.
Installing Underlayment & Flashing
Before the new shingles or tiles go on, roofers install:
• Underlayment: A protective layer that provides waterproofing.
• Flashing: Metal pieces around chimneys, vents, and roof edges to prevent leaks.
Proper installation of these components is critical to prevent water infiltration and extend the roof’s lifespan.
Installing the New Roof
With the base prepared, roofers install your chosen materials:
• Asphalt shingles are nailed in rows.
• Tiles or slate are secured according to manufacturer instructions.
• Metal panels are fastened and sealed properly.
Contractors ensure proper alignment, ventilation, and overlap to maximize protection and durability.
Final Inspection & Cleanup
After installation, the roofing team will:
• Inspect the roof for proper installation, alignment, and secure flashing.
• Remove all debris, nails, and leftover materials from your property.
• Ensure gutters and downspouts are functioning properly.
• Walk you through the completed work and answer any questions.
A thorough inspection guarantees quality workmanship and ensures your new roof is ready to withstand the elements.
