Our Services


We have years of experience with every type of siding: vinyl, the most popular; cedar, growing in popularity, especially with cement boards; and steel, a great maintenance free product, giving your home more value and you more time to enjoy life.


Roofing is one of the most important—if not the most important—items of residential construction. A roof can also give a home a facelift by enhancing its appearance and value. EDI is a fully certified, licensed, bonded and insured professional roofing contractor.

Commercial Roofing

One of the most difficult applications for the roofing business is that of the flat roof. Flat roofs are notorious for leaks. Extra attention and often higher cost are involved in order to protect a flat roof from leaks. With EDI, you can be assured there will be no leaks for the roof’s life.


Wood and vinyl replacement windows are the two most popular choices for your home. We can help you decide which one is best for you based on your needs. You can be assured that we will provide a quality product and installation no matter what you choose.


Updating your doors not only plays a large part in improving the energy efficiency of your home, but they also make a statement and provide a quick facelift to your home's exterior.

Soffit and Fascia

The soffit system provides much needed ventilation for the attic area—keeping moisture out in the winter months and lowering the attic temperature in the summer months—resulting in lower energy costs.


EDI offers seamless aluminum or copper gutters. We can match our aluminum gutters to any siding color. A full analysis is made of your home and grading to ensure proper drainage at your foundation, and oversized downspouts are used on all installations.


Inadequate insulation and air leakage are the leading causes of energy waste in homes. We can help you navigate the many considerations of new insulation including the R-value and type of insulation and whether it is blown in or installed in rolls.
