National Exteriors | Roofing Services in Cherry Hill, NJ 08003

Our humid climate and exposure to salt air can accelerate corrosion on the metal flashing that seals joints around chimneys, vents, and skylights. Corroded flashing loses its seal, leading to leaks and potential water damage inside your walls. At National Exteriors, our roof inspection specifically checks for this issue. We repair or replace corroded flashing with high-quality, corrosion-resistant materials, ensuring a tight seal to protect your Cherry Hill home from water intrusion.

Damaged underlayment—the water-resistant barrier beneath your shingles—often shows as interior water stains, peeling paint, or a musty smell in your attic. In many Cherry Hill homes, this damage is caused by prolonged moisture or previous storm damage that went unnoticed. A simple patch isn't always sufficient, as the underlayment is a critical component of your roof's defense. Our thorough inspection assesses the extent of the damage. We may recommend targeted roof repair or, if the underlayment is extensively compromised, a section reroof or full roof replacement to ensure your home's structure is fully protected.

Absolutely. We are your full-service solution. A leak from a damaged underlayment or corroded flashing can quickly lead to mold growth and structural water damage inside your home. National Exteriors first fixes the source of the problem with expert roof repair or replacement. Then, our certified restoration team takes over to safely perform mold remediation and water damage restoration, drying out affected areas and repairing interior damage.
