How to Find a Roof Leak
Inspect Your Attic for Signs of Leaks or Wet Spots
Your attic will be a good area to check for signs of a leak. Using a flashlight look for dampness or wet spots. Checking on a rainy day is the best time to see where there might be water penetration. It should be easy to find wet spots or mold because of the rain.
Follow these wet spots to the highest point in the attic, which is more than likely the source of the leak. Note or mark this area for further inspection.
Typical areas of water penetration are pipe gaskets, seals around vents, clogged gutters, dormers, and loose shingles.
Use caution when getting on top of your roof. A damaged or old roof is or could be an unstable area which can lead to a fall. Additionally, if you are not used to walking on a roof, a fall is more likely to occur.
The Cons of 3-Tab Shingles
3-tab roof shingles are a type of lightweight asphalt shingle roofing material commonly used in American residential homes. Known for their ease of installation, adequate durability, and standard affordability, they remain a popular choice with many homeowners.
However, 3-tab shingles tend to have less overall durability when compared to their architectural shingle counterparts. When properly maintained, architectural shingle roofs can last anywhere from 18 to 30 years. Depending on the local climate, a standard 3-tab shingle roof usually lasts between 7 to 10 years. Even in a mild climate, they typically never last longer than a maximum of 15 years.
Additionally, 3-tab shingles typically consist of thin frames, making them less resistant to high winds, uplifts, and other types of wind damage. 3-tab shingle roofs typically do not last long in neighborhoods with winds more intense than 60 to 70 mph.
