Question Answers
After a storm in Bloomington, my roof looks fine but I'm worried about wind damage. What should I look for?
Even without missing shingles, high winds can cause subtle but serious damage. We recommend checking for lifted or damaged roof flashing—a common post-storm issue here—as this can lead to leaks. Also, look for granule loss in gutters, creased shingles, or any signs of uplift. For peace of mind, our professional roof inspection can identify hidden wind damage and recommend repairs before minor problems become major leaks.
Can you fix a roof flashing lift, and will it prevent future leaks in our climate?
Absolutely. Repairing or replacing lifted flashing is one of our most common services in Bloomington. We don't just patch it; we assess the underlying cause, use proper sealing techniques, and ensure it's integrated correctly with your roofing system. Properly installed flashing is critical for withstanding our freeze-thaw cycles and heavy rains, creating a long-term barrier against water intrusion.
I need a new roof and siding. Can you handle both, and are there benefits to doing them together?
Yes, as a full-service contractor, we expertly manage both roofing and siding projects. Coordinating them offers significant benefits for Bloomington homeowners: it ensures a seamless weather barrier, allows for better integration of components like drip edges, and can be more cost-effective. We can also address any underlying storm damage discovered during the process, giving your home comprehensive protection and a unified, updated look.
