Roof Repair in North Hollywood

The houses are mostly wartime and 1950s, one story, stucco, on flat rectangular lots that were orchard before the tracts came. On the Los Angeles County Assessor's 2025 roll, 38 percent of the single-family parcels inside North Hollywood carry a year built between 1940 and 1945, and another 33 percent between 1946 and 1959, so roughly seven in ten went up inside twenty years. Gable and hip roofs, shallow pitch, composition shingle. None of the geometry is hard. Sun is what finishes them. NOAA's 1991 to 2020 normals put the average August high at Burbank Airport, sitting right off the northeast corner of the neighborhood, at 88.9 degrees, against 76.7 at LAX. Ten to twelve degrees of that from July through September cooks the oil out of an asphalt shingle. You see it as curled tabs along the west and south edges, bare patches where the granules have gone, and grit in the bottom of the gutter.

The apartment stock is the other half of the work. The land use table in the North Hollywood-Valley Village Community Plan puts 1,365 net acres under multiple-family designations, a fifth of the plan area, against 2,193 acres of single family. On the ground that is duplexes, fourplexes and two-story walk-ups with the parking tucked underneath, and on the same assessor roll about two thirds of them were up before 1960. The covering is a granulated cap sheet or a rolled membrane, draining to interior drains or out through a scupper in the parapet. They give up at the seams, at the drain bowl and at the base flashing where the parapet meets the field. Water sits on these roofs, so the failure is quiet. By the time a stain shows in a unit below, the deck has been wet a while.
