Roof leaks are among the most common issues homeowners face, and while they may start small, they can quickly turn into major problems if not addressed promptly. Water intrusion can lead to structural damage, mold growth, and costly repairs. Identifying the source of a leak is not always straightforward, as water often travels before it becomes visible indoors. A methodical inspection process is essential to determine the cause and protect your home from further damage. In this blog post, the experts from Suburban / Larchmont Roofing walk you through an inspection process that you can try.
Begin with an Interior Assessment
The first signs of a roof leak usually appear inside the home. Water stains on ceilings, bubbling paint, or warped drywall often signal moisture intrusion. These interior clues provide a general direction but may not reveal the exact entry point. Inspecting the attic is the next logical step. Using a flashlight, look for damp insulation, stained wood, or areas where mold has begun to form. During daylight hours, shutting off attic lights can make it easier to spot small openings where sunlight filters through the roof deck. These same openings often allow rainwater to enter.
Inspect During or After Rainfall
One of the most effective ways to pinpoint a leak is to check the attic while it is raining or immediately afterward. Listen for the sound of dripping water and trace it back to its origin on the roof structure. Keep in mind that water can run along rafters before dropping, so the visible drip may not be directly beneath the exterior entry point. Marking the area will help when you proceed to an outdoor inspection.
Evaluate the Roof Exterior
A thorough exterior inspection of the roof should follow. Common problem areas include missing, cracked, or curled shingles, as well as damaged flashing around chimneys, skylights, and vents. Flashing is particularly vulnerable, as even minor gaps can allow significant amounts of water to penetrate. Gutters also play an important role in preventing leaks. If they are clogged, water can pool and push under the shingles, mimicking a roof leak. Regular maintenance and cleaning of gutters help minimize this risk.
Controlled Water Testing
If the source of the leak is still unclear, a controlled water test can provide clarity. With one person stationed inside the attic, another can use a garden hose to slowly apply water to specific sections of the roof. By working methodically and waiting several minutes before moving the hose, you can simulate rainfall and determine where water enters. This process requires caution and patience, but it is often effective in identifying hidden leaks.
