Replacing a roof in Silver Spring
About 41 percent of Silver Spring homes were built before 1960, and the largest group dates from the 1960s. Roofs on houses of that age have usually been replaced before, sometimes by laying new shingles over old ones, which makes a full tear-off the clearest way to see what the deck looks like.
Signs that patching has run its course include brittle or missing shingles across several areas, sagging between rafters, recurring leaks in different rooms, and a roof that is simply past its rated life.
Storm wind is a recurring theme in Montgomery County, which logged 443 thunderstorm wind damage reports. Ask each contractor for the shingle's wind rating and whether impact-rated products make sense for your house.
Only about 38 percent of homes here are owner-occupied, so if you own a rental or a unit in a shared building, check whether association or historic rules also apply. Montgomery County says covering-only replacement most likely needs no county building permit, but structural work may. Since the requirement depends on scope, verify it with the Department of Permitting Services. Then work out the material, the timeline, the length of the manufacturer's material warranty, and what happens to the old roofing once it comes off.
