Roof Replacement for Irvington homes and buildings
For many Irvington property owners, roof replacement means a flat roof: on a three-family, on the rear section of a two-family or on an apartment or mixed-use building. A new flat roof is only as good as its drainage, edges and wall flashing, so replacement is the time to correct the slope, replace scuppers and rebuild parapet and wall details.
We install single-ply membrane systems on flat roofs, with tapered insulation where drainage needs correcting, and architectural asphalt shingles on sloped roofs. On two-families with both, we replace them together and detail the junction so the leak that usually develops there is designed out.
Occupied buildings and narrow lots need a plan. We schedule work so each section is closed up daily, protect neighboring properties, coordinate tenant notice through the owner and manage debris in tight spaces.
Irvington housing
Irvington's housing is dense and mostly early 20th century. Frame two- and three-family houses, many with a front gable and flat or low-slope rear sections, line most residential streets on narrow lots. Brick apartment buildings and mixed-use buildings along Springfield Avenue and other corridors have flat roofs with parapets. Many houses were built with brick chimneys for coal heat, and three-family houses often have flat or nearly flat roofs.
Weather & exposure
Irvington is largely flat to gently rolling, so wind exposure is moderate, but houses stand close together and many are three stories, which puts their roofs and chimneys above the neighbors and into the wind. Close spacing means runoff and ice from one roof affect the next. Flat roofs on three-families and apartment buildings pond during heavy downpours, and freeze-thaw cycles work steadily on old masonry.
When replacement is the right call in Irvington
Replace a flat roof when it ponds over large areas, has widespread cracking or blistering or has been patched in many places. Replace a shingle roof when it is curling, bald or leaking in several spots. If the chimney needs a crown, repointing or rebuild, coordinate it with the roof.
For multi-unit buildings, tell us about tenant schedules, parking and access. That lets us plan the work so the building stays dry and the disruption is short.
