Population: 70,000+ · County: Montgomery County · State: Maryland
Montgomery County sees the full Mid-Atlantic spectrum: 90°F+ humid summers, freeze/thaw winters, nor'easters off the Chesapeake, and an average 41 inches of annual rainfall. Roofs, windows, and siding installed here have to handle thermal cycling, wind-driven rain, and ice damming at the eaves.
Most exterior projects in Montgomery County require permits issued through the county's Department of Inspections, Licenses, and Permits. PCR pulls every permit under our MHIC #140855 license and coordinates rough/final inspections so you don't have to.
Maryland follows the 2018 IRC with state amendments. Roof underlayment requires ice & water shield at all eaves, valleys, and penetrations. Replacement windows must hit ENERGY STAR Climate Zone 4 (U-factor ≤0.30, SHGC ≤0.40). HOAs in many Montgomery County communities also require pre-approval for color, profile, and material changes — we handle the submission packet.
Family-owned, GAF Master Elite certified (top 2% nationally), 4.8-star Google rating across 100+ reviews, lifetime workmanship warranty, and crews that live and work in Montgomery County. We answer the phone, show up when promised, and clean the site every night.
