Solar Integrated Roofing, an integrated, single-source solar power and roofing systems installation company, completed the acquisition of Cornerstone Construction, a provider of construction services. Financial terms were not disclosed. "I would consider this to be a model acquisition and yet another example of how our roll-up model creates opportunities to deliver synergies by cross selling across our roofing and solar products. As we continue to grow our presence nationally, we will continuously seek out exciting new acquisitions such as this. I look forward to continued execution in the months ahead, helping to create long-term value for our shareholders," David Massey, Solar Integrated Roofing CEO.
