Baltimore's 42" of annual rainfall creates real conditions for moss and algae growth, especially on north-facing or shaded roof sections — algae-resistant shingles and more frequent inspections are worth considering here.
Baltimore's temperature range doesn't impose the kind of seasonal sealing or safety constraints seen in more extreme climates, so roofing work can generally be scheduled with more flexibility here than in places with harsher winters or summers.
Algae-resistant architectural shingles or standing seam metal (metal typically lasting 40-70 years in Maryland) tend to outperform standard 3-tab asphalt given Baltimore's 42" of annual rainfall, since both shed water well and resist moss/algae growth better.
Yes — Maryland requires roofing contractors to hold a valid license through Maryland Home Improvement Commission. Always verify a contractor's license status directly with Maryland Home Improvement Commission before hiring, not just by taking their word for it.
In Maryland, asphalt shingles typically last 20-25 years; metal roofing lasts 40-70 years; tile roofing lasts 50+ years, though actual lifespan depends heavily on local climate, installation quality, and maintenance.
Baltimore averages 42 inches of rain per year, with average temperatures ranging from 53°F to 70°F. Homeowners here should factor local weather patterns into material choice and maintenance timing — a contractor familiar with the area can advise on what performs best given these conditions.
