The Initial Inspection and Estimate
When you contact a roofing company, the process typically begins with an in-person inspection of your roof. A qualified representative will assess the condition of your existing roofing material, the underlying decking, flashing, ventilation, and any specific areas of damage or concern. Based on this assessment, they will provide a written estimate for the recommended scope of work. A thorough estimate from a reputable roofing company will specify materials, labor, disposal, timeline, and warranty terms — not just a total number.
Choosing Your Materials
If a full replacement is recommended, you will be guided through material choices. Most residential roofs use asphalt shingles, available in standard three-tab and premium architectural or dimensional styles. Architectural shingles have a thicker, layered appearance and longer warranties than three-tab. Other options include metal roofing, wood shakes, and tile. Your roofing company should explain the cost, longevity, and appearance tradeoffs of each option to help you make an informed choice.
Permits and Scheduling
A reputable roofing company handles the permit application on your behalf. Most residential roof replacements require a permit, and the permit process ensures code compliance and provides a record of the work for future buyers and insurers. Once the permit is approved, the project will be scheduled based on weather, material availability, and the company’s production schedule. Expect to be given a start date range rather than a fixed day, as weather is always a variable.
What Happens on Installation Day
A roofing crew will typically begin by setting up safety equipment and protecting your landscaping and driveway with tarps and boards. They will remove the existing roofing material to the decking, inspect and repair any damaged boards, install a new waterproof underlayment, and then apply the new roofing material from the bottom up. Flashing is carefully installed or replaced around all penetrations. A magnetic roller will be used to pick up stray nails from the yard when the job is complete.
The Inspection and Final Walkthrough
After installation, request a thorough walkthrough with the project manager. Look for uniform appearance, clean edges and valleys, proper ridge cap installation, and quality flashing work at chimneys and vents. The company should provide you with all permit documentation, material warranty paperwork, and their own workmanship warranty documentation. A quality roofing company considers the job complete only when you are fully satisfied.
