Step-by-Step Roof Replacement Process

1. Initial Inspection & Assessment
Every project begins with a detailed roof inspection by our experienced team. We assess the condition of your existing roof to determine whether a repair or full replacement is necessary.

2. Removal & Deck Repair
Once replacement is confirmed, we carefully remove the old roofing materials and inspect the roof deck underneath. Any damage—such as rot, sagging, or soft spots—is repaired to ensure a stable base for your new roof.

3. Waterproofing Layer Installation
Next, we install a high-quality waterproof underlayment that protects the roof deck from moisture and adds an extra layer of defense against New Jersey’s changing weather conditions.

4. New Roofing Installation
We offer a wide variety of roofing materials including asphalt shingles, metal roofing, tile, and more. Our skilled installers follow industry best practices to ensure every layer is properly sealed, secure, and visually appealing.

5. Final Touches & Cleanup
After the roof is installed, we add flashing and sealing around chimneys, vents, and other vulnerable areas. We clean the site thoroughly—leaving your property better than we found it.

Is It Time to Replace Your Roof?

Your roof is your home’s first line of defense. If you’ve noticed any of the signs below, it may be time to consider a full replacement:

Your roof is over 20 years old (depending on material)
Missing, cracked, or curling shingles
Leaks or water damage inside your home
Daylight visible through the attic ceiling
Moss or algae growth eating away at roofing material
A sagging or uneven roof deck

Ignoring these signs can lead to costly structural issues. Schedule an inspection with Njall Construction to know for sure.

What Affects the Lifespan of Your Roof?

Several factors impact how long your roof lasts. Being aware of them can help you decide between a repair or replacement.

Weather & Climate: Harsh winters, heavy rain, and UV exposure gradually wear down even the best materials.
Material Type: Different roofing materials offer different lifespans (see guide below).
Installation Quality: A poorly installed roof won’t last—no matter the material.
Ongoing Maintenance: Regular inspections and minor repairs extend your roof’s durability.
