Any business owner knows that a problem can get out of hand quickly. When your roof leaks, it can cause problems with customers and/or tenants, you may incur damaged inventory and possible mold/water damage issues in the future. Taking care of roofing issues timely and with care, the first time is extremely important. Here at Gen Ex, roofing with care is our passion. Not only for the property owner but for our own gratification. We take pride in our work and have built a reputation on those values. Many of our jobs come from referrals and we have worked hard and continue to do so to maintain that recognition. 

We can handle multi-structure properties and can help you with any roof that you need. It doesn’t matter if you’re a restaurant, retail store, or a mall; if you have a small building or a huge complex, we can help.

Since 2004, Gen Ex has been working with business and property owners to keep the rain out. No project is too big or too small for us to handle. When you call us, we will give you a same-day quote for what you need. Our hard work and customer service helped us achieve an A+ rating with the Better Business Bureau. Fully licensed and insured, you can be sure that you’re going to have the job done right when you go with Gen Ex.

Below are some recent multi-tenant property projects we have completed.
