What makes ACI Exteriors the right choice for you?

We are locally owned and have been improving homes and repairing roofs since 2001. We have earned the Certification of being a "GAF Certified Master Elite" Roofer EVERY YEAR since 2009, making ACI Exteriors the first and oldest Master Elite in the area. Due to stringent standards, only 1% of all roofing companies locally, and 3% nationally have achieved this status!

What does this mean to you?

  • We use GAF Shingles, the leader in laminated fiberglass and the highest quality roofing supplies
  • We are mandated to 6 nails per shingle rather than cutting corners using just 4 nails like many other companies
  • A 25-50 year warranty is provided on materials depending on the type and grade you choose
  • We are properly insured and licensed
  • On-going professional training is a priority to ensure the newest high quality materials and workmanship

We also have five stars on Home Advisor and are accredited by the Better Business Bureau.
