Rodent Removal in Kensington and Talmadge

The Spanish Revival houses that fill Kensington and Talmadge carry clay tile roofs, and the gap under the first course of tile at the eave is where most roof rats enter. Kensington's map was filed in 1910 and its housing stock is mostly late 1920s; Talmadge Park was laid out in the same decade and its original tract was added to the National Register of Historic Places in 2024. On both sides of Fairmount Avenue the roofs are the same age, and a bird stop that was fitted in 1928 has had close to a century to rust, crack or fall out. Where it has, the void under the tile runs the length of the eave and a rat has a covered corridor straight into the attic.

The fix is the same component the builder used, in modern metal. A bird stop, or eave closure, is a code-approved metal part, usually 26 gauge galvanized steel or aluminum, sometimes ventilated with weep holes, and the US Department of Energy lists fitting bird stopping among its recommended measures for tile roofs. A cheap quote for the same eave usually means a blob of expanding foam pushed under the tile, and foam is chewed through within a season. Rodent exclusion on a Kensington or Talmadge roof means metal closures along every eave, fitted under the tile so the street view is unchanged.

Both neighborhoods sit on mesa tops edged by canyons, and the houses along the rims share a boundary with year-round roof rat habitat. Ward Canyon, once Kensington's western edge, now lies under the freeway, but the finger canyons that cut into the rim streets are still open, still wet at the bottom in the rainy season and still full of the cover a rat wants. The slopes below the rim houses are planted with ivy, bougainvillea and mature trees, and the county's own guidance names ivy, dense vines, palms with dead-frond skirts and citrus as the places roof rats nest before they move to a roof.

A rat that lives on the slope has several routes to the eave. A branch over the roof, a fence top that runs to the garage wall, the cable and phone lines that come in at the corner of the house, a palm trunk beside the patio. Roof rats are climbers and use each of these as a road, according to the University of Florida extension, which also puts their normal range at about 150 yards from where they nest. Cutting the branch back and trimming the palm skirt takes away the easy road. It leaves the canyon full, which is why the house itself gets sealed. Roof rat removal on a rim lot is trapping inside plus metal at every opening, in that order.

Most 1920s houses in Kensington and Talmadge stand on a raised foundation with a crawl space, and the crawl space is inspected as carefully as the attic because rats use it the same way. Foundation vents sit around the perimeter at grade, and the original screens are thin wire that rusts through. A vent behind a shrub that nobody has looked at in years is an opening. Once inside, the rat has the underside of the whole floor to travel and the plumbing chases to climb.

A full inspection here has three parts: the crawl space with a light along every vent and the sill, the attic with a look at the top plates for droppings, and the roofline from a ladder with each eave checked for its bird stop. The contractor we route writes each opening down with a price beside it. The homeowner who wants a documented starting point before any work can book the rodent inspection on its own; it is free either way. Being told by a neighbor that a few rats are normal in a canyon neighborhood does nothing for the person lying awake under them. The contact page and the phone, answered 24 hours a day, both start the same process.
