When inspecting your roof in New Jersey, look for signs of damage like missing, curled, or blistered shingles, loose or exposed nails, rusty or corroded flashing, and signs of moisture or leaks in the attic.
Shingles:
- Missing, curled, or blistered shingles: These are signs of aging and potential damage.
- Loose or missing shingle granules: Granules are a protective coating on shingles, and their loss indicates that the roof is losing its weatherproofing.
- Loose or exposed nails: This can lead to leaks and further damage.
- Broken or loose shingles at the ridge and hip lines: These areas are particularly vulnerable to wind and weather damage.
- Improperly seated nails that “popped”: This can be a sign of improper installation or damage.
Flashing:
- Signs of missing caulk to seal flashing: Flashing seals around chimneys, vents, and other penetrations, and missing caulk can lead to leaks.
- Rusty or corroded metal flashing: Corrosion weakens flashing and can lead to leaks.
- Damaged or missing flashing: This can expose the roof to the elements.
Attic:
- Signs of moisture or leaks: Look for stains, discoloration, or mold growth, which can indicate leaks.
- Sagging or structural issues: A sagging roof can be a sign of underlying problems that need attention.
- Insulation: Ensure insulation is continuous and uninterrupted, and that it is installed according to the type of roof construction.
- Ventilation: Check that roof ventilation is provided by vents installed in the upper and lower portions of the roof, such as ridge vents and soffit vents, or by other approved methods, such as gable vents or roof turbines.
