New Roof Installation: Step-by-Step Process Explained

When the rain won’t let up and your home sounds like a drum, you know it’s time. Whether you’re planning ahead or staring down storm damage, a new roof isn’t just another weekend project. It’s protection, comfort, and peace of mind—layer by layer. At Pro Roofing, we’ve installed thousands of roofs for homes and businesses just like yours, including urgent emergency roofing calls and planned new construction.

Let’s walk through exactly what happens when you need a new roof, step by step. From the first hammer swing to the final inspection, here’s how our crew gets it done—and how you can feel confident every shingle of the way.

Pre-Installation Prep 📝

Before any tools are lifted, preparation sets the tone for the entire project. Think of this step as laying out your ingredients before baking a cake. No surprises. No missing pieces. Here’s what happens:

• Site Assessment: Pro Roofing inspects your roof, gutters, flashing, and attic. We check for leaks, wood rot, signs of previous repairs, and insulation issues.
• Material Selection: Together, we’ll choose what suits your property—shingles, metal, tile, or eco-friendly options. This depends on your budget, climate, and style.
• Permits & Paperwork: Most towns require a permit. We handle the paperwork, following local building codes and manufacturer instructions.
• Timeline Scheduling: Weather and job size matter. Residential projects often take 1–3 days; commercial jobs can take longer.
• Protecting Your Property: We cover landscaping, move outdoor furniture, and set up safety barriers. Your home or business stays clean and safe throughout.

Tip: Ask for a copy of your chosen material’s warranty and safety data sheet. It’s your roof—know what’s going over your head.

Tear-Off & Decking

It’s demolition day. Old shingles, damaged gutters, and worn-out flashing come off, like peeling back old wallpaper to start fresh.

• Removing Old Roofing: We use specialized tools to strip away every layer down to the decking. This isn’t just about looks; hidden issues can lurk underneath.
• Decking Inspection: The wood deck is the skeleton of your roof. We check for rot, water damage, and structural issues. Any bad boards get replaced—no shortcuts.
• Decking Repair: If repairs are needed, we use code-compliant lumber and fasteners. According to the International Building Code (IBC), all roof sheathing must be securely attached and free of decay.

Underlayment & Flashing

This step is like pulling on a raincoat before stepping outside. Underlayment and flashing keep water out and comfort in.

• Underlayment Installation: We roll out water-resistant barriers (synthetic or felt) over the decking. This layer is your home’s last line of defense against leaks.
• Flashing Placement: Metal flashing is installed around chimneys, valleys, skylights, and vents—anywhere water might sneak in. Proper flashing is crucial for long-term performance.
• Ice & Water Shield: In cold climates, we may add extra waterproof barriers at eaves and valleys to prevent ice dams.

Tip: Ask your installer about the type of underlayment used—synthetic options often last longer and resist moisture better than traditional felt.

Installing Materials

Now comes the transformation. This phase is like snapping together puzzle pieces—precision matters.

• Starter Strips: Laid along the eaves and rakes for extra wind resistance.
• Main Roofing Material: Shingles, metal panels, or tiles are installed in a staggered pattern for strength and water flow.
• Ridge Caps: Special shingles or metal pieces cover the roof’s peak, sealing out water and wind.
• Gutters & Downspouts: If needed, new gutters, downspouts, and gutter guards are installed for smooth drainage.
• Vents & Skylights: Ventilation and insulation upgrades can be added for better energy efficiency. Skylight and chimney flashing are installed or replaced.
• Sealants & Coatings: All penetrations and flashing joints are sealed with premium, weather-rated products.

Clean-Up & Final Inspection 🧹

A messy job site isn’t just unsightly—it’s unsafe. We believe in leaving your property cleaner than we found it.

• Debris Removal: All old materials, nails, and packaging are swept up and hauled away. We use magnetic rollers to catch stray nails.
• Gutter Cleaning: Any debris from installation is cleared out, ensuring proper flow.
• Inspection: Our project manager does a full walk-around, checking for overlooked details, loose shingles, or missed spots. We follow manufacturer checklists and local codes.
• Final Walkthrough: We invite you to inspect with us, answering questions and pointing out key features.
• Warranty Paperwork: All material and labor warranties are provided. Most manufacturers require proper installation for warranty coverage—another reason to work with trained professionals.

The Roof Installation Timeline

How long does it really take? Here’s a typical breakdown:

• 1–2 days: Prep and tear-off for average-size homes
• 1 day: Decking repair and underlayment
• 1–2 days: New material installation, flashing, gutters, and skylights
• 0.5 day: Clean-up and final inspection

Weather and job complexity can add time—especially for commercial roofing or custom eco-friendly options. Emergency roofing projects may require temporary repairs before full replacement.

Warranty Details You Should Know

Warranties aren’t just fine print—they’re your safety net. Here’s what you can expect from most new roof installations:

• Manufacturer Warranty: Covers defects in materials, often 20–50 years for shingles, metal, or tile.
• Workmanship Warranty: Covers labor and installation errors. Pro Roofing provides written documentation at project completion.
• Gutter and Accessory Warranties: Check for separate coverage on gutters, skylights, and specialty features.

Remember: Warranty coverage can be voided by improper installation, unapproved repairs, or lack of maintenance. Always keep records of inspections and gutter cleaning.

Safety Procedures On Every Job 🦺

Safety is never optional. Pro Roofing follows OSHA (Occupational Safety and Health Administration) guidelines on every site.

Our crew uses:

• Fall protection gear: harnesses, ropes, and anchors
• Safety barriers and warning signs
• Proper ladder and scaffolding placement
• Eye, ear, and hand protection
• Daily safety briefings

Tip: Never walk on your roof yourself. Leave inspections and repairs to pros with the right training and equipment.

Practical Tips for Homeowners & Building Managers

• Clear driveways and outdoor spaces before the crew arrives.
• Move vehicles to protect them from falling debris.
• Notify neighbors if noise or access might be an issue.
• Ask your installer for daily progress updates.
• Plan for pets and kids—roofing is loud!

Why Choose a Professional? DIY vs. Call a Pro

Replacing a roof is more complicated than a quick paint job. The risks—falls, leaks, poor ventilation, voided warranties—aren’t worth it.

When to call Pro Roofing:

• If you see water stains, missing shingles, or storm damage
• If your roof is over 20 years old
• For emergency roofing needs, like leaks during storms
• For upgrades like new gutters, skylights, or eco-friendly options

DIY is best left to minor tasks like cleaning gutters or trimming branches. Anything more? Call a pro.

Emergency Roofing: What To Expect

Sometimes, you don’t have the luxury of planning. Hail, wind, and fallen trees can leave you exposed.

In an emergency, Pro Roofing will:

• Arrive quickly to assess and contain damage
• Install temporary tarps or patches to prevent further water intrusion
• Prioritize safety, following all local code requirements
• Communicate clearly about next steps, timelines, and costs

Tip: Take photos of the damage before any work starts for insurance documentation.

Local & Seasonal Considerations 🌦️

Roofs behave differently in winter, summer, and storm season. Here’s what to keep in mind:

• Winter: Ice dams and snow can slow work and require extra protection.
• Spring/Summer: Ideal for installation, but be ready for pop-up storms.
• Fall: Great for prepping before winter, especially gutter cleaning and flashing checks.

Always ask about weather delays and how your installer handles seasonal challenges.

Maintenance & Prevention After Installation

A new roof is an investment—protect it with simple care:

• Schedule annual inspections by a qualified contractor
• Clean gutters and downspouts at least twice a year
• Trim trees that hang over the roof
• Watch for signs of leaks or missing shingles after big storms
• Consider sealants and coatings for extra protection
