Washington, D.C. sits at the intersection of humid subtropical and mid-Atlantic climates. Summer humidity averages 70 percent. Attics turn into ovens. The urban heat island effect amplifies temperatures by 5 to 10 degrees in neighborhoods like Foggy Bottom and Columbia Heights, where rooftops absorb and radiate heat all night. When you install new shingles over old ones, you create a thermal sandwich. The bottom layer traps moisture. The top layer cooks in the heat. Both layers degrade faster than they would alone. This is why reroofing over existing shingles in the District often fails within five to seven years instead of lasting the expected 15 to 20.
