  • "Keystone was my top choice of 5 contractor proposals I solicited. Their GAF Master Elite and Presidents Club designation , highly rated customer reviews and on site product and installation knowledge and expertise made them one of my top two contractor options. Once coupled with the best product adjusted cost proposal and highly personalized sales interaction and experience, Keystone was my pick. A very challenging multi section roofing project was completed in a mere two days by a team of five highly qualified, professionally skilled GAF certified installers. Working from early morning to dusk, the team worked tirelessly to complete every aspect of a GAF Golden Pledge certified roofing system installation. I highly recommend GAF and Keystone Roofing & Siding for your home project. Thank you Doug (sales) and Chris (manager and foreman) for providing personalized and highly professional guidance throughout my roofing project."

  • "We recently had our roof replaced by Keystone. Prompt response, competitive pricing, excellent workmanship. Great job protecting our landscaping and cleanup was complete. Only found one 5 inch piece of old roofing in one of our bushes and one nail after the work was completed. It’s a good idea to be out of the house when the work is being done to avoid the noise. Highly recommended!!"
