The Mcgill Group | General Contractors & Roofing in Cheltenham, MD 20623

We understand that the local climate can challenge roofing systems. For ventilation, we assess your attic space to ensure proper intake and exhaust, which regulates temperature and moisture to prevent ice dams and premature aging. For flashing—the critical seals around chimneys, vents, and valleys—we use durable, corrosion-resistant materials and precise installation techniques. During any roof inspection or replacement in Cheltenham, we pay special attention to these vulnerable areas to ensure your roof is protected against the elements for the long term.

Yes, we offer a fully integrated service. Our team manages the entire process, from the initial custom design consultation—where we discuss styles from modern to farmhouse to fit your taste—through to the final construction, plumbing, and electrical work. This single-source responsibility means smoother communication, consistent quality, and a cohesive result that aligns with your vision and lifestyle, all while maintaining our standards of professionalism.

We provide a range of durable roofing options suited to different architectural styles and budgets. This includes various shingle types like architectural, asphalt, cedar, and composite, as well as flat roof systems such as modified bitumen, rubber membrane (EPDM), and built-up roofs (BUR). We'll discuss the pros, costs, and longevity of each material to help you choose the best solution for your Cheltenham home.
