Signs of a roof leak indicate a major problem that will only get worse. The longer you wait, the more expensive it will be to repair. Water has a way of getting through the smallest hole, crack, or crevice it can find. Common signs are often more evident after it rains. Here are some of the things to look for if you want to catch a roof leak early.
Water Spots Are Appearing on the Ceiling
Yellow water spots on the ceiling mean it is coming from somewhere. The roof is a good place to look because it is a common entry point. Oftentimes the source of the water is far from the place on the ceiling where you see the staining. Water can travel along lumber framing, roof panels, and other structural elements and soak through insulation first. If leaky windows or pipes are not the cause, then it’s time to check out the roof.
Outside Walls Have Water Stains
If water stains are showing up on the walls, it can indicate roof problems with the step flashing. The problem may start with a rainstorm or get worse when it rains, as when you see water spots on ceilings. Leaky windows or junctions between siding materials can also cause water stains on the walls.
Roof Shingles Are Cracking or Cupping
Missing granules eventually lead to brittle shingles, and any cracks can allow water to seep through and contact other roofing materials. Old, worn shingles also start to cup, or develop a wavy appearance as the corners turn up. Wind-blown rain can get under the shingles and continue its way into the house.
Roof Shingles Are Missing
If shingles are missing, chances are the sealant underneath is damaged. Singles are overlapped to prevent water entry. When this pattern is altered, water can easily pass through, collect under the outer layer, and find a way to seep through underlying layers of the roof.
Temperature Fluctuations Trigger Leaks
Freeze-thaw cycles can trigger roof leaks if there are ice dams. When ice builds up on the roof and blocks melting snow from draining, the water can get under the shingles. All you need is an inch or two of snow for this to happen. Seeing a leak inside the house after a thaw is therefore evidence of a roof leak you should investigate sooner rather than later.
Even if the leak isn’t constant, but rather a slight drip from time to time in your house, it may be due to a leak in the roof. The problem might go away for a while. You should still have it checked out, because any moisture problem can cause permanent damage and get worse over time. Don’t ignore the problem if the signs point to the roof leaking. Contact a professional such as Metropolitan Contractors that can get to the root of the problem, and recommend the best ways to fix it, so you avoid more serious and very expensive problems down the line.
