Roof Leak Diagnosis Day (Amamori Shindan no Hi) — June 11th
Industry DaysWhat Is Roof Leak Diagnosis Day?
June 11th is celebrated every year as "Roof Leak Diagnosis Day," established by the NPO Japan Roof Leak Diagnosis Association. The date falls right around the start of Japan's rainy season, and the day aims to raise awareness of the importance of early detection and early repair of roof leaks in homes.
Warning Signs of Roof Leaks to Check Before the Rainy Season
Roof leaks are often caused by cracks and deterioration in roofs and exterior walls, and if left unaddressed, they can lead to rot in structural materials (wood and steel reinforcement) and health problems from mold. Before the rainy season hits in earnest, it's important to check the roof, ceilings, exterior walls, and around windows and sashes.
- Stains or discoloration on ceilings or walls
- Moisture or mold around window frames and sashes
- If you can access the attic, check insulation material for dampness or discoloration
Consult a Professional
Trying to fix a roof leak yourself based on guesswork carries the risk of missing the root cause. Hiring a professional, such as a certified roof leak diagnostician, to accurately pinpoint the cause before repairs helps extend the life of your home. As the rainy season approaches, take a moment to think about giving your home a health check.
