In this episode of Roofing Road Trips, Heidi J. Ellsworth welcomes Mark McMillan with Horn Brothers Roofing and Randy Miller with Allrite Home and Remodeling to talk about how they navigate the process of getting DaVinci composite slate and cedar roofing materials approved by historical preservation commissions when reroofing historical buildings.  Both are long-time roofing professionals who share how education can be one of your most powerful tools when seeking approval. Join us to hear how each was able to successfully secure approvals for projects in Denver and Milwaukee, bringing these historic homes back to their original majestic beauty.
