Calvert County Roof Types and Ages
Calvert County has the oldest median housing of the three Southern Maryland counties we serve, which is why so many roofs here deserve an honest assessment now.
- 1990Median year built across Calvert County
- 41%Of county homes built from 1980 to 1999
- 32%Of county homes built before 1980
- 10%Of county homes built in 2010 or later
More than 80 percent of American homes wear asphalt shingles, which last about 20 years as three-tab and 30 as architectural, while metal runs 40 to 80. With a 1990 median build year and Bay-side weather speeding things up, many Calvert County roofs are on borrowed time. A free inspection tells you where yours stands, and we will not push a replacement you do not need.
