Energy Efficient

Rooftop Photovoltaic Power Solutions – A rooftop photovoltaic power station, or rooftop PV system, is a system that has its electricity-generating solar panels mounted on the rooftop of a residential or commercial building or structure.  The various components of such a system include photovoltaic modules, mounting systems cables and solar and other electrical accessories.

Features and Characteristics of Photovoltaic Roof Systems

  • Offset energy expenses
  • Tax incentives or Carbon Points (where applicable)
  • Feed solar electricity into the public grid 


Rapidly evolving building codes and energy code compliance can be a challenge to stay up to date with. Additionally, tax incentives or special programs may offer benefits worth considering. To ensure your project is up to code and you are getting the best return on investment, McDonald Roofing uses specialized software to identify and calculate the energy cost per year of your current or proposed roof system.

McDonald Roofing also deploys infrared technology to discover potential energy loss on your existing roof and its components.

Roof Coatings

Coatings provide a cost-effective method for restoring most single-ply commercial roof membranes, as well as offering increased energy efficiency. For best results, a good substrate is required.

Coating an existing roof is a cost effective way to extend the life of an existing roof system and is less disruptive to building occupants.

Features and Characteristics of Energy Saving Roof Coatings

  • Up to 20% lower utility bills
  • Decreased thermal stress – extend the life of the roof life
  • Downsize HVAC, leading to capital cost savings
  • Lower peak air conditioning demands
  • Low-odor products are available in a variety of colors.
