We install vinyl, fiber cement, wood, and metal siding tailored to match your home's style and budget, providing a durable protective barrier against rain, snow, wind, and UV rays, while improving insulation, reducing energy costs, and delivering a low-maintenance exterior that adds long-term resale value to your property.

Gutters
We install gutter systems that channel rainwater away from your foundation, protect your landscaping from erosion, prevent water backup that leads to rot and mold, guard against ice dams in winter, and extend the life of your siding by keeping moisture off your home's exterior year-round.

Frequently Asked Questions
We serve Findlay, Lima, Bowling Green, Tiffin, Port Clinton, and surrounding communities across Northwest Ohio, and our reputation is built on showing up when we say we will, finishing jobs in one day when possible, and leaving job sites clean. We are an Owens Corning Platinum Preferred contractor, BBB accredited, and factory trained and certified. Customers consistently tell us they appreciated how hard and careful the crew worked, how quickly the job was completed, and that what Joe said they would do, they did, every single time.
Most residential roof replacements we complete in a single day. Customers in Findlay and Lima have told us they were amazed their entire roof was done before the crew left that evening. We show up prepared, work efficiently, and clean up thoroughly before we consider the job done. If you have been told by other contractors that you are weeks out, give us a call. We have consistently been able to schedule and complete projects much faster than the competition without sacrificing quality.
Yes. Beyond roof replacement, siding, and gutters, we also offer roof repair, professional roofing inspections, attic insulation, and a service called Shingle RX, which is a roof rejuvenation treatment that can extend the life of an aging but structurally sound roof. We also carry DaVinci premium roofing products for homeowners looking for a high-end aesthetic. Whether you need a full replacement or just want to extend what you have, we have options that fit different needs and budgets.
Shingle RX is a roof rejuvenation treatment designed to restore flexibility and extend the life of asphalt shingles that are aging but not yet at the end of their useful life. As shingles age, they lose the oils that keep them pliable and resistant to cracking, and Shingle RX replenishes those oils to slow the deterioration process. For homeowners who are not ready for a full replacement but want to get more years out of their current roof, it can be a cost-effective option. We are happy to assess your roof and let you know honestly whether Shingle RX or a full replacement makes more sense for your situation.
The most common signs are age, with most asphalt roofs lasting 20 to 25 years, along with curling or missing shingles, granule loss showing up in your gutters or on the ground, dark streaks or moss growth, sagging areas, or recurring leaks that keep coming back after repairs. If you are seeing any of these, schedule a free inspection with us and we will give you an honest assessment. We have completed jobs where homeowners received four or five quotes and chose us not just for price but for the quality of the work, and we are happy to walk you through exactly what your roof needs before you commit to anything.
