If you used a cheap $10 aerosol can as your "Instant Roof Nui Crack," you have roughly 6 months. Start calling roofers for quotes now. Do not wait for the next rainy season. Roofers are cheaper in the summer (dry season) than during the winter storms.

The "Nui" (new) crack needs time to skin over. Even instant sealants need 15-30 minutes to set before downpour intensity returns.

Meet David R. from Austin, Texas. During a derecho storm (inland hurricane), a 6-inch crack opened in his 10-year-old composition roof. Water poured into his living room. he climbed a ladder

A roofing contractor quoted $5,000 for "emergency tarp and new shingle section." David had $40 in his pocket.

He bought a 12-inch roll of Instant Roof Nui Crack from a local hardware store ($18.99). Despite the rain still falling (65 mph winds), he climbed a ladder, dried the crack with a towel for 5 seconds, peeled the tape, and slapped it on. He rolled it with a soda can.

Result: The leak stopped immediately. Three years later, that patch is still holding. David used the $5,000 savings to redo his kitchen instead.
