What if my new roof leaks?


Maintain your composure. Roof leaks are a natural occurrence, so don't scream at your roofing contractor or think of your leaking roof as a personal assault on you. Instead, contact your roofing contractor and explain the issue in detail. There's no need to exaggerate the leak, and it's crucial to justify your situation calmly and clearly. You would expect the leak to be patched if you made the right decision in hiring a competent roofing contractor. Roofing contractors often provide warranties on their work, and even if they don't, most are concerned enough with their reputation to rectify the situation and ensure that your roof is in good working order. All of our work comes with a 5-year NO LEAK warranty from Champion Exteriors. Keep calm, call your roofing contractor, explain the issue plainly, and set a deadline for completion.
