Dallas Roofing: Article About Roof Leaks
The number one reason why Dallas roofing professionals are called to a home is because of a roof leak. Identifying the source of a leak can often be a lot harder than fixing the problem that led to the leak. This is because gravity and liquid adhesion could mean that water is penetrating the roof in one location and winding its way through the home before it drops on the back of the ceiling. There are some areas of the roof that are more prone to leaks than others.
Plumbing penetrations, including things like plumbing vents, exhaust flutes, ventilation fans and ducts, are necessary parts of a home's design. When rubber boots and metal flashings around pipes become cracked or damaged, they become a prime location for leaks.
Flashings are strips of metal that are used to cover seams or transition points in a roof. They cover areas where water usually gathers, like valleys and around the chimney. When the flashings become damaged or corroded, or when they fall off altogether, they will allow water to penetrate the roof and eventually leak into the home. Flashings will often fail around skylights and chimneys.
Shingles and other roofing material, though designed to protect the home from water filtration, are not designed to last forever.

On average, an asphalt shingle lasts between 12 to 25 years. Things like sun exposure, mildew and moss growth, as well as wind, hail and snow accumulation may cause a shingle to fail prematurely and lead to roof leaks. Nails that are driven into shingles but not sealed with roof cement tend to leak. On metal roofs, homeowners should look for signs of corrosion around nails and fasteners. This is especially the case if the nails are made from a different material than the roof.
Roofs that experience negatives temperatures during the winter can become affected by ice dams. Ice dams happen when a roof is not adequately insulated and so heat accumulates at higher parts in the roof, causing the snow to melt. As the snow melt travels down the roof and comes into contact with the cooler eaves, it refreezes. This process repeats until a ridge of ice forms on the roof. This ridge serves as a dam, which causes future melting snow to pool and not refreeze. Over time, this water will penetrate underneath the roofing material and can lead to a leak.
Tracing the source of a leak can be a challenge. However, if a homeowner works with a roofing professional, they will be able to identify the source of the leak and then come up with a repair or replacement plan.
