Why Choose ASI

Listen to Dave Phillips, ASI's CEO describe how ASI is different from other commercial roofing companies in Central and Western Ohio.

Planning Before Any Project

At ASI we take the time to understand a customer’s needs and conduct a full evaluation of the roof or project before we create a scope of work. This due diligence allows us to assess the composition, age and remaining life of the roof system and provide immediate and long-term recommendations with an accurate timeline and estimate. We will then work directly with you to provide education, so you are aware of your options and have the knowledge to better budget for capital expenditures and feel confident you are making the best decision. Ultimately this planning reduces surprises, extended timelines and budget overruns so we can deliver innovative solutions as we maintain our schedule and budget.

Clear Communication Throughout

Providing great customer service through clear, transparent communication and quality craftmanship is at the heart of what we do. We never want you feeling confused or not understanding the status of your project. Therefore, we utilize an online portal that allows customers to view what we have completed, before and after photos via reports, and are always aware of the status of  your most important asset. This not only provides peace of mind, but also allows you to use the information to better communicate with your own teams or other construction partners.

Ongoing Relationships

We take pride in the fact that our customer relationships are built over time, based on taking the time to understand your needs, providing education and informed recommendations along with quality workmanship and customer satisfaction, resulting in over 75% customer referrals. And know you will always get personalized attention and service, in-person education, follow up and proactive responses to emergency situations through our 24/7 response team.

Our Mission

To help you realize your construction investment with high performance, cost effective roofing materials and service for long term sustainability. ASI Commercial Roofing & Maintenance has been dedicated to providing the best and most innovative roofing services to central Ohio’s businesses for almost 20 years (over a decade). ASI has been the go-to team for high quality construction projects for both new and replacement roofs and offers 24-hour emergency maintenance. In today’s economy it is imperative that companies have a roofer they can rely on, and ASI prides itself on being that roofer.

James Hardie

Since 2013, HardiePlank® lap siding has been backed by the coveted Good Housekeeping Seal from the Good Housekeeping Research Institute.  For over a century, the Good Housekeeping Seal has been a symbol for reliability that consumers trust when making big decisions, like choosing home siding.

The seal is a sought-after mark of quality and is granted only after a product’s rigorous evaluation.  The engineers from the Good Housekeeping Research Institute evaluated HardiePlank lap siding for fade, weather, water, fire resistance and more using state of the art equipment.  Since James Hardie has its own rigorous testing process, this recognition comes as a particular point of pride and we’re determined to live up to that honor every day.
