Roof Installation Checklist: Signs Your New Roof Was Done Right in New Jersey
A new roof is a major investment, and once the installation is complete, homeowners want to feel confident that the job was done correctly. Harsh winters, humid summers, and unpredictable coastal storms make proper roofing especially important in the Garden State. If you’re looking for a reliable guide, here’s a roof installation checklist—signs your new roof was done right in New Jersey.
1. Clean, Straight Shingle Lines
One of the easiest ways to evaluate the quality of your roof installation is by looking at your shingle pattern. The shingles should be:
Straight
Evenly spaced
Lying flat
Aligned consistently across the roof
Crooked or wavy lines may indicate rushed workmanship or poor attention to detail.
2. Proper Flashing Installation
Flashing is essential for preventing leaks, especially in areas where water tends to collect. In New Jersey’s heavy rains and winter snowmelt, proper flashing matters even more. Check areas around:
Chimneys
Vents
Skylights
Valleys
Dormers
Flashing should be sealed, secure, and neatly installed with no gaps.
3. Good Ventilation click here System
A well-installed roof includes proper ventilation. Without it, New Jersey humidity and seasonal heat can lead to mold, attic moisture, and higher energy bills. Your roof should have:
Ridge vents
Soffit vents
Balanced airflow throughout the attic
A professional roofer ensures both intake and exhaust vents are functioning correctly.
4. Clean Edges and Drip Lines
The edges of your roof should be clean and precisely finished. Drip edges help direct water away from the fascia and foundation—crucial during New Jersey’s heavy rainfall. Signs of good installation include:
Metal drip edges installed along eaves and rakes
No exposed wood
Tight, secure edge shingle placement
5. No Visible Nail Issues
Nail placement determines the long-term durability of your new roof. A professional installation ensures:
Nails are not overdriven
Nails are not popping through shingles
Nails are placed in the correct nailing strip
No exposed or rusting nails
Bad nailing jobs can lead to blown-off shingles during New Jersey storms.
6. Proper Underlayment and Ice Shield
New Jersey homes benefit from ice and water shields—especially near the roof's edges—due to winter freeze-thaw cycles. A correct installation includes:
Premium underlayment installed under the shingles
Ice and water shield installed along eaves, valleys, and other vulnerable areas
No gaps, wrinkles, or tears in the material
7. Clean Jobsite and Debris-Free Home
Professional roofers don’t just install the roof correctly—they clean up afterward. Signs of a quality roofing company include:
Zero leftover nails
No shingle scraps in the yard
Clean gutters and downspouts
Proper disposal of old roofing materials
This reflects attention to detail and respect for your property.
8. Clear Warranty and Documentation
A well-installed roof should come with:
A manufacturer’s material warranty
A workmanship or labor warranty
Proper paperwork, receipts, and written guarantees
If your roofer provided all necessary documents, that’s a strong sign of a professional job.
