Customer Reviews
10 reviews
Cornerstone Construction handled both our roof replacement and solar panel installation. Having one company do both made the whole process seamless. Excellent quality work.
Great experience with the solar installation. The team was professional, the work was clean, and they coordinated perfectly with the roofing side of the project.
Cornerstone is the real deal. They know roofing and solar inside and out. The solar shingle option they presented was something no other company offered. Very satisfied.
