A leaking roof causes damage to your attic insulation and roof deck causing mold and mildew growth and reduced energy efficiency. Roof leaks have several causes, all of which require the assistance of a professional Roofing Contractor. Here are some common causes of a roof leak:
Loose, Cracked or Rotting Shingles
The biggest cause for roof leaks. If your roof is older, you may see signs of cracking or rotting in the shingles. Also, shingles may come loose and go missing. A weakened outer layer will expose your home to the elements, which wears on the under layers and eventually cause leaks to form. If your roof is in such a condition, you need to have it inspected.
Roofing Nails Backing Out
Apart from roofing shingles, roofing nails can sometimes back out. This leaves small holes that water can easily penetrate, and leave your shingles unstable. Such little holes are typically unnoticeable to an untrained eye, however, a good roofing inspector is trained to see the signs of nails backing out.
Damaged or Dislodged Flashing
Flashing is a piece of metal that protects the areas of your roof where it meets a vertical surface (i.e. walls). If flashing is damaged or dislodged by strong winds, this could leave those areas of the roof exposed. A perfect way for rainwater to get in.
Cracked Rubber Boots
Plumbing vents and anything that protrudes from the roof require a rubber “boot,” which works like flashing by protecting the area where it meets the roof. Continued exposure to outside conditions will eventually crack or dislodge the rubber boot.
