Elsewhere in the township, 1950s through 1970s capes, ranches and split-levels have the usual mid-century weak points: cracked pipe boots, rusted step flashing at sidewalls and dormers, nail pops and worn valleys. Asset Roofing & Chimney repairs steep-slope shingle and low-slope membrane roofs, which is essential in a town where a single house often has both.
Repair or replace? What we tell Denville homeowners
On a lake home, we start by mapping the roof sections and their ages, because a leak that appears in one room often enters at a joint several feet away. Where shingles are still sound, repairs focus on the transitions: new flashing where an addition meets a wall, membrane carried under the shingles where a low-slope section meets a pitched one, and metal in valleys that were woven without it.
Moss removal should be gentle. Pressure washing strips granules and shortens roof life. We remove moss by hand and with appropriate treatments, replace shingles that are already damaged beneath it, and recommend trimming limbs where that is practical to let the roof dry.
