Top 7 Roofing Problems in New Jersey Homes (and How to Spot Them)
New Jersey’s four-season climate — from humid summers to snowy winters — puts a lot of stress on your roof.
Whether you live along the shore or in the suburbs, your roof faces wind, rain, snow, and temperature swings that can lead to costly problems if left unchecked.
At LGM Roofing, we’ve seen it all. Here are the top 7 roofing problems NJ homeowners face, how to spot them early, and tips to prevent major damage.
1. Ice Damming in Winter
What It Is: Ice dams form when heat escapes from your attic, melting snow on the roof. The water refreezes near the eaves, creating a dam that forces water under your shingles.
Signs to look for:
✔️ Large icicles along roof edges
✔️ Water stains on ceilings or walls during winter
✔️ Curling or lifting shingles near the eaves
Prevention tips:
Ensure proper attic insulation and ventilation
Clear gutters before winter
Use a roof rake to safely remove excess snow
2. Wind Damage from Storms
What it is: High winds from storms or hurricanes can loosen, lift, or completely tear off shingles, leaving your roof exposed to leaks.
Signs to look for:
✔️ Missing shingles or visible patches on the roof
✔️ Creased or curled shingles
✔️ Loose flashing around chimneys or vents
Prevention tips:
Choose wind-resistant shingles rated for NJ weather
Have a post-storm inspection to catch hidden damage early
3. Moss and Algae Growth
What it is: Moisture-rich environments, like NJ’s humid summers, encourage moss, algae, and lichen to grow on roofs – especially shaded areas. Over time, they can lift shingles and cause rot.
Signs to look for:
✔️ Green moss patches or dark streaks on shingles
✔️ Shingles that look damp or warped
✔️ Soft or rotting roof sections
Prevention tips:
Trim back overhanging trees to allow sunlight
Install zinc or copper strips to prevent growth
Schedule professional cleanings every few years
4. Leaks Around Flashing
What it is: Flashing is the metal material installed around chimneys, skylights, and vents to seal joints. When flashing cracks, rusts, or loosens, water can leak into your home.
Signs to look for:
✔️ Water stains near chimneys or skylights
✔️ Rust or lifted flashing visible from the ground
✔️ Drips or dampness in the attic during rain
Prevention tips:
Inspect flashing during seasonal roof checks
Replace old or corroded flashing promptly
5. Poor Ventilation
What it is: Without proper airflow in the attic, heat and moisture build up, causing premature roof aging, mold growth, and ice dams.
Signs to look for:
✔️ Excessive attic heat in summer
✔️ Mold or mildew smell in the attic
✔️ Warped roof decking
Prevention tips:
Add ridge and soffit vents
Make sure attic insulation doesn’t block airflow
6. Gutter Clogs and Overflow
What it is: Clogged gutters prevent water from draining, causing it to pool at the roof’s edge and seep under shingles.
Signs to look for:
✔️ Overflowing gutters during rain
✔️ Sagging or detached gutters
✔️ Rotting fascia boards
Prevention tips:
Clean gutters twice a year (spring and fall)
Install gutter guards to block debris
7. Aging or Worn Shingles
What it is: Over time, shingles lose granules, crack, and warp. Old roofs are more vulnerable to leaks and storm damage.
Signs to look for:
✔️ Bald patches on shingles
✔️ Shingles curling or cracking
✔️ Roof over 20 years old
Prevention tips:
Schedule annual roof inspections after the 15-year mark
Replace damaged shingles promptly to extend roof life
