The Various Ways Moisture Can Damage Your Roofing System

Every roofer you meet will tell you that moisture is the number one enemy of your home’s roofing system. After all, it’s the roofing problem that can cause the most damage to your roof. There are many ways moisture can damage your roof, and it’s best that you know them all so you can be prepared in the event that it does wreak havoc on your roof.

Sagging Ceiling

A sagging ceiling is one way you can tell that moisture has affected your roofing system. This problem is usually characterized by a bubble-like buildup that makes the ceiling curve downward. Once you spot a sagging ceiling, this means there’s already a buildup of excess water and moisture in your attic, or the roofing system itself is heavily compromised.

Mold Growth

Mold is a late stage sign of your roof being affected by moisture. Once you start spotting mold growth on your ceiling or your interior walls, it means your roof is leaking and has already penetrated your interiors. This can spell bad news for you as mold growth can greatly affect the health of your household members.

Wood Rot

Wood rot is a difficult sign to spot and will usually happen when the moisture levels of your roofing material reach 20%. If this goes undetected for a lengthy amount of time, this can cause a lot of problems for your home and will likely cause your roof’s integrity to deteriorate.


Corrosion is another moisture issue. Every roofing system is attached to the overall structure of your home with metal fasteners and connectors. Unfortunately, metal is vulnerable to corrosion when it comes into contact with large amounts of water. With that in mind, be sure to have regular roofing inspections at least twice a year to see if your roof has corrosion.
