Roof Installation Checklist: Signs Your New Roof Was Done Right in New Jersey
A new roof should give you peace of mind — not second guesses. But how can you really tell if your roofer did the job right? From the ground, everything might look fine, yet hidden mistakes can lead to leaks and early wear. Here’s a checklist every New Jersey homeowner should use to confirm their new roof was properly installed.
1. Straight, Even Shingle Lines
Stand back and look at your roof. Shingles should be perfectly straight and consistent. Wavy or uneven rows usually mean sloppy installation — and those spots are often the first to leak when storms hit.
2. Proper Flashing Around Roof Penetrations
Flashing protects your roof’s weak points: chimneys, skylights, and vents. If you see excessive sealant or uneven metalwork, your roofer might’ve cut corners. High-quality flashing should look neat and sealed tightly to the surface.
3. No Exposed Nails or Loose Shingles
Every nail should be driven below the shingle surface, not sticking out or visible. Loose or lifted shingles are a major red flag — especially on a new roof.
4. Secure Drip Edges and Gutters
Drip edges keep water from seeping under the roof. They should run along all eaves and rake edges. If your roof lacks drip edges or gutters weren’t reattached properly, call your contractor immediately.
5. Proper Ventilation and Ridge Caps
Good ventilation keeps your attic cool in summer and dry in winter. Ridge vents and soffit vents should be cleanly installed and evenly spaced. Without ventilation, your roof’s lifespan will drop dramatically.
6. Clean Worksite and No Debris Left Behind
Professional roofers respect your property. A clean yard, no leftover nails, and well-disposed materials show attention to detail — both on and off the roof.
7. Warranty and Documentation
You should receive written proof of your roof’s warranty and installation details. This includes material information, warranty registration, and inspection reports. If you didn’t get them, request copies right away.
