Why Roof Replacement Matters

Your roof plays a vital role in protecting your home from Pittsburgh’s unpredictable weather, including heavy snowfall, strong winds, and heavy rainstorms. Over time, roofing materials wear down, and delaying replacement can lead to leaks, structural damage, and increased energy costs.

Common reasons homeowners choose roof replacement:

• Aging roof (20+ years old)
• Extensive storm damage
• Persistent leaks or mold issues
• Worn-out or missing shingles
• Increased energy bills due to poor insulation

If you're unsure whether your roof needs to be replaced or just repaired, read our blog post, "The Pros and Cons of Roof Repair vs. Replacement".

Step-by-Step Process of Roof Replacement

A well-planned roof replacement ensures the job is done efficiently, safely, and with long-lasting results. Below, we break down each phase of the process so you know exactly what to expect.

Step 1: Roof Inspection & Assessment

Before a roof replacement begins, a thorough roof inspection is necessary. During this stage, a roofing contractor will:

• Examine the current condition of your roof
• Identify damaged shingles, leaks, mold, or structural issues
• Check attic insulation and ventilation
• Determine if there is any rotting or damaged roof decking

Based on the assessment, your contractor will recommend the best roofing materials and provide a detailed estimate for the project. To learn more about the importance of inspections, read "The Benefits of Regular Roof Inspections".

Step 2: Choosing Roofing Materials

The roofing material you choose will impact the durability, energy efficiency, and aesthetics of your home. Pittsburgh’s climate requires strong, weather-resistant materials that can withstand heavy rain, snow, and fluctuating temperatures.

Here are some of the most popular roofing options for North Hills homeowners:

• Asphalt Shingles – Lifespan of 20-30 years. This is the most affordable option, easy to install, and well-suited for Pittsburgh’s climate.
• Metal Roofing – Lifespan of 40-70 years. Known for its energy efficiency, durability, and resistance to wind and snow, metal roofing is a great long-term investment.
• Slate Roofing – Lifespan of 50-100 years. A high-end roofing choice that offers exceptional durability and an elegant aesthetic.
• Wood Shingles/Shakes – Lifespan of 30-40 years. Provides a natural look with good insulation properties, but requires more maintenance.
• Rubber (EPDM) Roofing – Lifespan of 25-35 years. A strong choice for flat or low-slope roofs, offering excellent waterproofing and longevity.

Your contractor will help you choose a roofing material that fits your budget, climate needs, and aesthetic preferences to ensure the best long-term performance for your home.

Step 3: Preparing for Roof Replacement

Once materials are selected, preparation begins. Before installation:

• Schedule the project – Roofing work typically takes 1-3 days, depending on the size and complexity.
• Secure permits – Most Pittsburgh-area municipalities require permits before roof work begins.
• Protect your home – Move outdoor furniture, cover landscaping, and inform neighbors about the project.

Step 4: Removing the Old Roof

The first major step of installation is removing the existing roof. Contractors will:

• Remove shingles, underlayment, and flashing
• Inspect the roof deck for rotting wood or weak spots
• Replace any damaged decking to ensure a strong foundation

Pro Tip: A full tear-off (rather than layering shingles over the old roof) ensures longer durability and better protection.

Step 5: Installing Roof Underlayment & Flashing

Before the new shingles are installed, essential protective layers are added:

• Ice & Water Shield – Prevents leaks caused by ice dams and heavy rain
• Synthetic Underlayment – Provides a second layer of waterproof protection
• Flashing Installation – Metal flashing is added around chimneys, skylights, and valleys to prevent leaks

This step is crucial in extending the lifespan of your new roof.

Step 6: Installing the New Roofing Material

With the underlayment in place, roofers will begin laying shingles, metal panels, or other roofing materials.

• Shingles are installed from the bottom up, ensuring proper overlap and waterproofing
• Ridge vents and attic ventilation are added to regulate airflow and prevent heat buildup
• Nails and fasteners are securely placed to withstand wind and rain

This phase typically takes 1-2 days, depending on the complexity of your roof.

Step 7: Final Cleanup & Inspection

Once the roofing material is installed, the crew conducts a thorough cleanup to remove nails, shingles, and debris from your yard and gutters.

• A final inspection ensures proper installation and that all seams are sealed, flashing is secure, and ventilation is optimized
• The contractor will review warranty details and provide you with maintenance tips

Your new roof is now ready to protect your home for decades to come!

How to Maintain Your New Roof

A well-maintained roof lasts longer and performs better in Pittsburgh’s harsh climate. Follow these tips to keep your roof in top condition:

• Schedule annual roof inspections
• Keep gutters clean to prevent water buildup
• Trim overhanging branches to avoid debris damage
• Check for missing or cracked shingles after storms
