What in Baltimore changes the job

Ask how the quote handles damaged decking; housing age is not roof age.

For extreme hail, NOAA says: “Extreme Hail: Roof damage possible to homes.” These report counts do not establish that impact level at your home. Ask the quote to name the wind and impact ratings of the covering it prices.

Median hourly wage for Roofers in the Baltimore-Columbia-Towson, MD area, May 2025: $27.11 (U.S. Bureau of Labor Statistics, Occupational Employment and Wage Statistics).

Each bidder appears under a stable label such as Contractor A, so you judge the work, not the brand.
