Through the Windows
Water can infiltrate the walls when rain seeps through the windows, between the sash and the jamb. It may trickle down to the wall studs, causing structural damage and mold.
Water Damage Underneath Siding
Water can leak through siding where it is loose or worn out, or if it was not properly installed. Common places for water to get in include the corners of the house, where siding panels meet, and under the trim around windows.
Under or Behind the Dishwasher or Clothes Washer
Water leaks can be hidden underneath or behind appliances like clothes washers and dishwashers. While appliances are sealed by design, leaks can develop in the water supply line to the machine. A slow drip can go unnoticed until you move the appliance to replace it with a new one. This risk illustrates the importance of having waterproof flooring in the laundry room and kitchen.
Around the Tub and Shower
Any water lines behind walls have the potential for leakage, so bathrooms are a place where this can occur. Plumbing connections are the most likely places for pipes to spring a leak. It’s difficult to notice that this is happening, and oftentimes the first sign is the floor feeling soft due to rotting, water stains on the walls, or water dripping from the ceiling below an upper-level bathroom.
Water Damage in the Cabinet Under Sink
One of the most common places for water damage to occur is cabinets underneath sinks. Usually, the damage is not too extensive because it is contained within a vanity cabinet, but it can grow mold nonetheless. Periodically check the cabinets for moisture and pipe discoloration.
Behind Exterior Faucets
The pipes attached to exterior faucets are susceptible to bursting when they freeze because they are exposed to outdoor temperatures. If this pipe bursts and leaks, it can saturate the siding and framing materials, causing water damage.
Water Damage Due to Failing Flashing
Roof leaks occur when the flashing around chimneys and other roof openings is damaged or deteriorating. Inadequate flashing is a common entry point for rainwater, which will damage the roofing boards, attic, and ceiling.
