Common Causes for a Leaky Roof

Water damage on ceiling

Hearing a dripping noise somewhere in your home is a major concern. While it can come from leaking pipes, another cause is a leaking roof. Roof leaks can become major issues as they can show that the roofing system is badly damaged and in need of immediate repairs. Check out the following common causes for a leaky roof:

Old or Damaged Shingles

Roof shingles act as a protective barrier from all weather. As the roof ages, the petrochemicals in asphalt shingles dry out, leaving the materials more prone to cracking, splitting, and curling. Also, shingles can become damaged by tree branches, hail, or other factors. Once the damage extends through the shingles, it allows water to penetrate and enter the home.

Damaged Flashing

Flashing are metal strips that line areas such as valleys, corners, or any protrusions such as chimneys and pipe vents. The material is used to seal places where different types of materials meet or areas where water may collect as it redirects the water down from the roof. If the flashing becomes damaged, this vulnerable place can allow water to enter.

Soffit and Fascia Problems

The edge of your roof has a fascia trim piece and the underside of the edge is called the soffit. The fascia helps prevent moisture from entering the roof edge while the soffit allows for attic ventilation. If there is a problem with the fascia or soffits, water can enter along the roof edges and get underneath the shingles and against the rafters, causing the materials to rot out and become moldy.

Clogged/Neglected Gutters

Gutters are designed to redirect water from the roof into downspouts and away from the home’s foundation. When a clogged or neglected gutter cannot redirect the water properly, the water can sit in the gutter and up against the roof edge. The water can begin rotting out the materials and allow the moisture to penetrate into the house.

Cracks in Your Chimney

Brickwork and mortar along the chimney can develop cracks due to age or damage. When the water enters, it can expand and contract based on outdoor temperatures, causing the cracks to grow bigger. Water can seep into the chimney and build up to the point where it can get to the roof materials and begin to rot them out until water gets into the house.

Keep in mind that roof leaks are not always obvious where water is dripping from the ceiling. Other signs of a leaky roof can be stained ceiling tiles, flaking wall paint, discolored walls, or mold growing along the ceiling or walls. Discovering the cause of these problems will allow you to get the roof repaired. For more information about roof issues, contact Brandstetter’s KangaRoof.
