Auburn Roofing: Article About Best Roof Leak Detection Practices
Roof leak detection is a complex problem solving activity meant for an experienced Auburn roofing professional. Because roofs are a system of varying layers, leaks within the home aren't necessarily right below the problem area. Water can travel for many feet and then drop into the interior. Homeowners should understand some of the best detection practices used by contractors to pinpoint leaks accurately.
Ideally, a roofer should visit a leaking home when water is actively flowing. Contractors use the water flow to find the leak's end and starting points. When only stains are present inside the home, determining the leak point is much more difficult. Contractors must take more time to look for multiple routes that could perpetuate a leak, such as a roof penetration entering the attic. If flowing water isn't occurring during a roofer appointment, contractors may create their own rainstorm by running hose water down the roof. Any leaks will show up with a rain simulation.
When leaks are difficult to pinpoint, the first roof areas professionals concentrate on are flashing. These metal pieces serve as transition areas between penetrations and shingles. Although strong, flashing can lift and curl from weathering damage. Professionals look for any moisture seeping underneath the flashing and repair the areas as necessary.

They may repair or replace the flashing based on the given leak issues.
Air pressure within the home should be relatively balanced with the outside, but structural issues can contribute to negative air pressure. In these cases, roof moisture is actually pulled into cracks and crevices. Professionals must alter the air pressure to reduce moisture pull. Ridge and soffit vents creating airflow between the roof's eave and peak alleviate pressure differences to ease leak potential.
Homeowners must be aware that shingle removal may be necessary to find leaks. When a leakage point is questionable, roofers remove a small shingle section. They'll survey the roof deck, underlayment and shingles for any anomalies. It may be necessary to remove and replace shingles in multiple areas based on the leak quantity. Leaks aren't always isolated to one area. Contractors will verify leak locations and offer a repair estimate based on their findings.
Provide enough space within the attic and interior spaces for contractors to examine ceilings and walls. Remove any furniture or wall hangings that can mask problem areas. With a clear view, contractors can find leaks accurately and prevent them from damaging any other structural areas.
