Maryland's roofing market spans a diverse range of conditions from the Chesapeake Bay coastline and Eastern Shore to the mountains of Western Maryland. The Baltimore and DC suburbs represent the dominant market, with a dense housing stock that generates consistent demand for roof replacements and storm damage repairs. Summer thunderstorms bring hail and high winds, winter brings ice and snow, and nor'easters can strike hard along the coast. Maryland requires roofing contractors to be licensed for home improvement work, which provides meaningful consumer protection. Before hiring anyone, these 21 questions to ask a roofing company are a smart place to start.

Roofing in Maryland: What Homeowners Should Know
Maryland homeowners face a mix of seasonal roofing stresses. Summer brings severe thunderstorms with hail and wind damage across the state, while winter brings ice storms and snow loads that challenge older roofing systems. Coastal and waterfront properties on the Eastern Shore and around the Chesapeake face additional wind exposure and salt air that accelerates wear on roofing materials and metal components. The high density of older housing in Baltimore and its suburbs means a significant portion of the market is in active replacement territory.
Maryland Roofing Contractor Licensing
Maryland requires home improvement contractors including roofers to hold a license issued by the Maryland Home Improvement Commission (MHIC). You can verify a contractor's license at dllr.state.md.us. Maryland also requires contractors to carry surety bonds and maintain liability insurance. The MHIC provides a recovery fund for consumers who suffer financial harm from licensed contractors, offering an added layer of protection.
Maryland Building Codes and Permit Requirements
Maryland has adopted the Maryland Building Performance Standards, which are based on the IRC with state amendments. Each county administers its own building permit program. Montgomery County, Prince George's County, Baltimore City, and Baltimore County each have distinct permitting processes. Permits are required for full roof replacements throughout the state. Contact your county's building permit office to confirm local requirements.
Call Before You Dig
Maryland law requires notification to Miss Utility 811 at least two business days before any digging. Call 811 or visit missutility.net. This applies to any excavation or ground work associated with a roofing or drainage project.
