At CI Roofing and Insulation, we take a ‘whole-house approach’ and evaluate every aspect of health, safety, comfort, and energy efficiency from the foundation to the roof.

Architectural Shingles

Traditionally, they are composed of a heavy fiber glass mat base and ceramic-coated mineral granules that are tightly embedded in carefully refined, water-resistant asphalt. Recently, however, a new product has surfaced on the market, synthetic slate (such as CertainTeed's Symphony Slate).

Metal Roofs

Metal roofs, made of galvanized steel, are very durable in cold weather and have a much higher solar reflectivity than shingles. These roof systems can also act as a radiant barrier, reducing your heating and cooling costs and maintaining a much more comfortable indoor climate.

Solar Tubes

SolarTubes can reduce the amount of energy and money you spend on lighting, as well as greatly improve a home’s appeal to potential future owners. At Constructive Ideas, we are happy to help you make this simple improvement by installing Solatubes throughout your home.

Whole House Assessment

We want to hear about your comfort concerns, see your energy bills, and diagnose the condition of your home’s major appliances. Using thermal imaging, we can look inside your walls, floors and ceiling and pinpoint problems that are otherwise invisible.

Air Sealing

According to the United States Environmental Protection Agency, reducing the amount of air leakage in your house is the single most cost-effective way to decrease your home’s energy use.

Attic Insulation & Ventilation

Your attic is a critical component in your home’s complex system of operation. Through a combination of air leakage and a lack of insulation, roughly 40% of your home’s energy is regularly lost through the attic.


We are a family-owned, family-operated, and family-oriented company.

See What Our Happy Customers Are Saying
I contacted Constructive Ideas in 2015 to see what they could do about my old, leaky house. For years I've dealt with cold breezes in the winter and the clouds of heat in the summer, all inside my house! Walking up and downstairs was like going from one extreme to another. Mike and Patty showed up and talked about a few different options. I decided to Air Seal and Insulate the second story of my house. That was the best home improvement decision I've ever made. This last year has been so pleasant inside, what a huge difference. I'm even seeing a difference in my power bill! I'd not only recommend CI for the quality of work and the results, but also for the character of the employees that came out to do the work. I'm always skeptical about strangers coming in my house to work, especially around my small children. But the team that came to my house was polite, friendly and hard working. When they were done my young boys weren't running around the house yelling all the "new" words that they could have picked up from these guys. Instead my boys saw young men working hard in order to make our house more comfortable and energy efficient. I'm very satisfied with Constructive Ideas and have recommended them friends already.

Constructive Ideas replaced my roof this spring. They were friendly and competent and did their best to pick up all the debris. Good job! I would definitely recommend them.

If you want something done right, you go to an expert. That's what I found when I went to C. I. to get a insulation check up for my home. They did a thorough exam of my house, made suggestions and installed new insulation, as well as sealing up any areas where drafts were a problem. As a result, both my heating and cooling costs were greatly reduced. They also helped me with updating the rest of my home. I highly recommend them based upon the thoroughness of their work, the efficiency, their cleanliness, and the attitude of doing what's best for the client. M. Grady
