Water has a tendency to travel, making it difficult to determine where leaks come from. Knowing the top 10 areas for leaks can help you avoid problems. Here are the first areas a roofing company will inspect when searching for a leak.
1. Valleys
Some metals expand and contract, causing them to crack over time. Experienced roofers know which flashing must be used and that shingles must also be properly cut.
2. Head-wall Flashings
A head wall is any spot where the roof meets a vertical wall. In addition to proper flashing against the wall, the flashing must also extend at least three inches over the shingles.
3. Wall-step Flashing
Another common site for leaks is along wall steps. These are areas where a vertical wall rises along with the roof, such as for a dormer.
4. Chimneys
While not every house will have head walls, many homes have a chimney. Even a hairline crack that forms above the flashing can result in a serious leak.
5. Plumbing Vents
Any protrusion in the roof can become a site for leaks. The plumbing pipe typically has a rubber seal with aluminum flashing. While most roofs will last more than 20 years, this seal can fail in only 10 years.
6. Furnace Vents
Not all furnace vents come up through a chimney. Some may be sealed with a metal storm collar, which may result in leaks if they become loose.
7. Ice Dams
When ice blocks the flow of water from melting ice on the roof, it can create an ice dam. The water will eventually back up under the shingles and result in water stains on ceilings.
8. Wind-driven Rain
Wind is a powerful force, and it can easily drive water under the shingles. You can avoid this problem by choosing professional roofers who will use quality felt paper and ice shield.
9. The Attic
Water stains inside the house aren’t always from the roof. High humidity levels in the attic create excessive levels of condensation, and the water will eventually find its way into your home.
10. The Shingles
Older roofs can leak when the asphalt shingles lose their protective granules.
