Flat and Low-Slope Roofing in Central Pennsylvania
Watertight low-slope systems with proper drainage, seams and edge details.
Low-slope roofs cannot rely on gravity to shed water the way steep roofs do, so drainage, seams and edge details matter. We install single-ply and modified bitumen systems with careful attention to slope, scuppers, drains and flashing.
Typical projects include rear additions, porch roofs, townhome roofs, dormer tops and small commercial buildings. We will review your existing drainage and recommend a system that fits the building and your budget.
