Our Founder

A Lifelong Passion for Excellence

When Chris Gonsalves founded Millstream Construction in 2009, his vision was to build a roofing company that provides a level of service not typically found in this industry. To this day, Chris and his tight-knit team use their 40+ years of experience to install the best roofing solutions in the area.

Customer-Centric Service

Building Trusting Relationships With Our Customers

Not only does Millstream Construction offer top-quality products and the best manufacturer warranties, but we aim to provide each of our customers with exceptional customer service and act as your partner during the process of your roof upgrade. In fact, customer-centric service is built into everything we do. We will solve your roofing issues, and also will partner with you through the entire process to ensure you are fully aware of the status and result of your roofing project. Every member of our team goes above and beyond so that you are happy with the service you receive. This includes everything from arriving on time, remaining in constant contact, working efficiently, maintaining top-notch workmanship standards, and providing a level of quality control that’s virtually unheard of in our industry. That’s the benefit of working with a roofing company that puts their customer first!

24/7 Emergency Services

We’ll Be There for You, Day or Night

When a storm tears through the area and leaves you with sudden roof damage, you can’t afford to wait. That’s why Millstream Construction provides emergency roofing services. Contact us after hours and a live receptionist will immediately notify our team. We’ll dispatch our trained estimators to come to your home and address the situation. And, since we’re designated as a Haag-certified inspector, we’ll be able to provide expert assistance for your storm damage and guide you through exactly what you need to do to remedy the damage.

The Best Installers

Our Highly Trained Installation Teams Allow Us to Consistently Pursue Excellence

While many companies may offer similar products, the key ingredients that set Millstream apart are our superior installation standards, use of quality products, and warranties. We closely monitor every project as it unfolds using special software, and one of our in-house roof managers will thoroughly inspect your roof using our multipoint final inspection. Combined with our factory-trained and certified installers and top-notch quality control, we maintain our status as both a GAF Master Elite® and Owens Corning® Platinum Preferred Contractor. These certifications are only awarded to the top contractors who provide superior installation, excellent customer service, and top-tier training programs. What these certifications mean for our customers is that their roofs are always supported by these stellar manufacturers and they can have confidence that in any situation they may find themselves, their home will always remain protected. Millstream Construction is proud to be one of only a select few roofing companies in the nation that hold both of these credentials with both manufacturers, setting the bar well above other companies in the greater Hartford area.
