A leaky roof can be caused by a variety of issues, from damaged shingles and clogged gutters to aging materials and severe weather. Even small leaks can lead to bigger problems like water damage, mold growth, and structural issues if left unchecked. Understanding the common causes of roof leaks can help you take preventive measures and address problems before they worsen.
Penetrations
Penetrations such as pipes, skylights, chimneys, and vents are common sources of leaks. Theses item are easily repaired and need to be inspected periodically by a roofing professional periodically or as soon as you notice a leak.
Damaged/Missing Shingles
Storms with high winds can blow off roofing material, especially if your roofing material is reaching the end of its service life. Hail and fallen tree limbs can cause holes in your roofing.
Flashing
Flashing is used at transitions between the roofing material, at penetrations, or at angle changes. This flashing can come loose, deteriorate or be damaged by the natural movement of your building structure.
Nail Pops
If you have damaged or deteriorated decking it loses its ability to hold the nail or fastener. Nail pops slowly move up and penetrate your roofing material, creating a leak.
Wear & Tear
All roofing material has a service life. It simply loses its ability to keep your home water tight.
Cable Guy
Unfortunately, sometimes cable companies drill holes right through the roof to run coaxial cable. This definitely creates leaks.
Always have a roofing professional examine your roof for proper repairs or replacement.
