Some red flags to be on the lookout for are missing or loose shingles, granules from asphalt shingles collecting in your gutters, excessive mold or moss growth, or any signs of staining on your ceilings or walls. The good news is, at Pritchett Brothers, we provide free roof inspections and home consultations. Contact us for a free inspection or estimate. Go online to pritchettbros.com.
