Dallas Roofing: Article About Common Roof Leak Locations
Rooftops use a complex system of layers to protect structures from extensive moisture damage. Every system has its weak and strong points, and rooftops are no exception to this rule. Dallas roofing professionals can evaluate a rooftop several times a year for preventive maintenance purposes, but leaks can develop between these visits. Ideally, homeowners should know about a rooftop's common leak points to be on the lookout for any problems during rainstorms.
Nearly all rooftops have valleys as part of their design. Valleys are where two pitched surfaces meet at a low point. Most valleys have metal flashing that lines their channels. However, inexperienced contractors may not secure flashing tightly to the adjacent roof sides. Leaks develop along flashing and rooftop connection points as a result of improperly applied fasteners. Homeowners can see these water leaks inside the home at almost any point along the valley's vertical length.
Shingles must cover all rooftop surfaces unless contractors add flashing instead. However, shingles can break off from rooftops and expose underlayment below. Leaks typically originate from exposed underlayment areas because this layer may not be entirely water resistant. For example, exposed roofing felt might have tears that allow moisture to seep down into the rooftop layers.

Leaks may travel throughout a home's attic spaces and along its rafters before homeowners see any staining on their interior surfaces.
One of the most common leak locations on rooftops is at penetrations. Skylights, chimneys and other penetrations must have proper flashing surrounding them to prevent leaks into the home. Flashing and fasteners can break down over time, however. Frequent preventive maintenance appointments are the only solution to find these worn penetration areas and secure them before leaks develop.
Rain gutters are an important part of rooftop systems because they direct water off of shingles and into proper drainage channels. Leaks often develop along older gutter channels at seam connections. Gutter seams may crack and become misaligned along fascia board, for instance. Water constantly leaks from these seams until roofers can repair the system. Although gutter leaks are exterior problems, they negatively affect the home with foundation puddling and possible structural shifting.
Interior leak locations are usually difficult to find unless there's obvious staining across some surfaces. Homeowners should start their interior leak inspection by looking closely at walls and ceilings. Mineral traces and yellowing stains, for instance, are signs that water has saturated an area. Document these locations and point them out to contractors when they arrive for their inspection appointment. These interior clues are valuable to any rooftop troubleshooting procedure and only help homeowners reduce their damage costs.
