Getting a new roof installation is a big decision, but don’t worry—we’re here to guide you every step of the way. Whether you’re replacing an old roof or building a new home, knowing what to expect can make the process smoother and less stressful.
In this guide, we’ll cover the full process of roof installation, from inspection to final inspection, and everything in between. You’ll also find tips, expert advice, and answers to common questions.
Step 1 – Initial Roof Inspection & Quote
Before anything else, a local roofing contractor will inspect your current roof. They’ll check for:
- Damaged shingles or flashing
- Water leaks or signs of rot
- Soft spots in the roof decking
- Ventilation issues in the attic
They’ll then provide a quote, often based on roof size, materials, roof pitch, and labor. If you’re shopping around, try searching for roof installation near me to compare options in your area.
Tip: Ask if they are certified by the NRCA (National Roofing Contractors Association) and if they work with top brands like GAF, CertainTeed, or Owens Corning.
Step 2 – Choosing Roofing Materials
Once you’re ready to move forward, it’s time to pick your materials. Common options include:
Asphalt Shingles

You’ll also decide on:
- Underlayment (felt or synthetic for waterproofing)

- Ridge caps and vents for attic ventilation
Step 3 – Permits, Codes & Scheduling
Roofing isn’t just about materials—it also involves paperwork.
- Your contractor will handle building permits
- The project must meet local building codes

FAQs About Roof Installation
How long does a roof installation take?
Most residential roof installations take 1–3 days, depending on size, complexity, and weather. However, unexpected delays due to weather or material shortages may extend the timeline.
What is the process for a new roof?
The process includes initial inspection, choosing roofing materials, getting permits, preparing the site, removing the old roof, installing the new roof, and performing a final inspection and clean-up.
How to prepare your home for roof install?
Protect your belongings indoors from vibrations, cover valuable landscaping, and inform neighbors about the upcoming noise and traffic. It also helps to make arrangements for pets who might be sensitive to construction sounds.
What are common problems with new roof installations?
- Poorly installed flashing that leads to leaks
- Lack of proper attic ventilation causing heat and moisture buildup
- Incorrect installation of underlayment
- Use of subpar or mismatched materials
- Not following local building codes, which could delay inspections
How do I choose the right contractor for my roof installation?
Look for contractors who are licensed, insured, and have experience with the roofing material you’ve selected. Read reviews, ask for references, and make sure they follow manufacturer installation guidelines to protect your warranty.

Although roofing over an existing layer might save on labor, a complete tear-off is generally recommended. It allows contractors to inspect and repair decking, install modern underlayment, and improve the longevity of your new roof.

Spring through early fall is typically the best time, as weather conditions are ideal. However, professional roofers can perform installs year-round depending on your location and the roofing system used.
