Even a small roof leak can result in thousands of dollars in damage if it's not repaired quickly. The excess moisture also encourages the growth of mold and mildew, which can cause allergies and other health problems. An experienced, certified Gaithersburg roofing professional can help homeowners find any leaks and repair them before they grow. Here are some common signs and sources of a leaky roof.

Water damage on a ceiling may not be coming from a hole in the roof directly above. The water could flow down the underside of the roof deck before touching the ceiling. A leaking roof can also cause peeling paint or cracks in walls. Use a pair of binoculars to look at the roof from the ground. Check for cracked or missing shingles, sagging areas, corrosion on metal roofs, and holes made by animals. The hole causing the leak may be too small to see from the ground, so homeowners should also check for any sign of water in the attic. Leaks there usually look like dark streaks on the underside of the roof decking. Follow these streaks to find the source of the problem.

Common sources of leaks include plumbing vent pipes, exhaust flues for appliances, attic vents, and ventilation fan ducts. These spots often leak because of worn or cracked rubber boots and metal flashing. Skylights and roof windows can leak as well. Any water near the downhill side of a skylight is a sure sign that the unit is leaking.

Ice dams are caused by warm air coming from attics. It melts snow on the roof, and the water then runs down toward the cold eaves and gutters and freezes again. Eventually, the ice accumulates under shingles where it melts and drips into homes. The added weight of the ice can damage gutters and downspouts. Icicles are an early sign of an ice dam. Homeowners should insulate living spaces well and ventilate attics to prevent ice dams and help lower heating bills. People can also remove snow from the roof before it has a chance to melt.

Leaks can be caused by a worn or damaged chimney. They can also come from the flashing around the chimney. Chimneys located anywhere but the peak of a roof should have a cricket, which is a triangular structure made of metal or shingles on the high side of a chimney. It keeps water and debris like leaves from accumulating at the base of the chimney and eventually causing leaks.
