Roofing Contractor in Walnut, CA

Walnut sits in the eastern San Gabriel Valley around Mt. San Antonio College. Traffic on the 60 or 57 can stretch the 80 minutes and 42 miles between our Torrance base and Walnut. Call before you plan around a visit and we will say plainly when we can be there, and whether a free estimate or roof inspection is the right first step.

Most Walnut homes went up between the 1970s and the 1990s on graded hillside lots, and a large share wear tile. Tile ages slowly, so the roof looks fine long after the felt underneath has dried and cracked. That gap between how a Walnut roof looks and how it performs is the reason owners here call us.

Tile-roof services that Walnut homes call for

Most requests fall into four groups, and the cards show how each fits a hillside tile home.

Why 1970s to 1990s tile roofs leak under Mt. SAC's hills

Underlayment, not tile, is usually what fails. After several decades of inland summer heat, the felt cracks at laps, nails and valleys, and water finds its way under tiles that still look sound. Slopes also bring broken tiles, since a hillside roof is often walked on to reach a view deck or satellite dish. Our slipped roof tiles guide explains what causes that movement, and the tile underlayment replacement page covers the bigger fix.

Lemon Creek, Snow Creek and graded pads: where the ladder starts

Walnut became a city in January 1959, and most of its tile housing came later, in tracts graded into the hills around Lemon Creek Park and the Snow Creek development. Graded pads put many houses above or below the street. A ladder may start on a slope, and tile bundles have to be staged where a roofer can reach them without a long carry. Tell us how your lot lies when you call. Homes in one tract were often finished within a year or two of each other, so a neighbor's re-roof is a fair hint about the age of yours.

Inland heat, solar panels and the underlayment question

Walnut summers run well hotter than the coastal air at our Torrance base, and that heat is what dries out felt under tile. Many tile homes here also carry solar panels now. Before tile is lifted for new underlayment, the panels have to come off and go back in step with the roofing, and we coordinate that timing with your solar company. Our solar panel detach and reset page explains the order of work. If you are weighing a patch against relaying the felt, the repair or replace guide shows where each one makes sense.

Valley Boulevard, the city counter and the county page

The City of Walnut, not the county, handles re-roof permits, since Walnut is an incorporated city. Permit paperwork on a re-roof is ours, and a call to the city will confirm what your address needs. Neighboring jurisdictions differ, as our Los Angeles County service area page shows.
