The answer to 'how often to replace emergency roof repair' is that emergency roof repairs are intended to be temporary fixes to stop active leaks or damage. They should be replaced with a more permanent roofing solution as soon as possible, typically within 6-12 months. Emergency repairs use materials like roof tarp, sealants, or patch kits that are not designed for long-term use. Leaving an emergency repair in place for too long can lead to further damage and leaks.
It's important to have a professional roofer inspect the roof and provide a comprehensive repair or replacement plan. They can assess the extent of the damage and recommend the best course of action, whether that's a permanent repair or a full roof replacement.
