Roof Leak Repair in Kensington, San Diego.
A water stain on the ceiling is not the leak. The leak entered 3 to 12 feet uphill from where it shows. We use moisture meter readings, physical inspection, and 15 years of San Diego leak patterns to find the actual source: pipe boot, step flashing, valley, skylight perimeter, mortar ridge, or seam.

Roof Leak Repair on Kensington homes
Kensington Drive and Marlborough Avenue run through blocks of consistent Spanish revival homes, with Terrace Drive and the Adams Avenue edge marking the neighborhood's boundary. Clay barrel tile is common across these blocks, original on many homes and matched on others where prior owners already replaced it. The underlayment beneath that tile is almost never original. Decades of heat cycling break down asphalt-felt underlayment long before the tile itself fails, which is why a lift-and-relay is such a frequent job here. Homeowners in Kensington also tend to care a lot about street-facing appearance, since the neighborhood's identity is built around its architectural consistency.
Clay tile dominance means most Kensington roof work is a lift-and-relay rather than full tile replacement: the tile comes off, gets set aside, new high-temp synthetic underlayment goes down, and the original tile goes back. That protects the tile and the neighborhood's look while fixing the actual failure point. Where tile is cracked or missing, matching the original profile and color matters for both curb appeal and neighborhood expectations.
Central San Diego leak diagnosis covers craftsman-era homes with original chimney flashing in Mission Hills and Kensington, flat porch roofs in North Park and Hillcrest with parapet drain failures, and older shingle homes in Talmadge and La Mesa where pipe boots and ridge flashing are at end of life. Tight lot access and mature trees make visual inspection from the ground unreliable; our inspection uses moisture meter and physical access.

Roof Leak Repair in Kensington: common questions
Does my Kensington home need new tile or just new underlayment?
In most cases it's the underlayment, not the tile. Clay tile itself can last well over 50 years, but the felt underneath it breaks down from heat exposure decades before that. A lift-and-relay removes the tile, replaces the underlayment with a high-temp synthetic, and resets the original tile. It costs a lot less than full tile replacement and keeps your roof looking exactly the way it did.
Can I switch my Kensington home from tile to shingle to save money?
You can, but most homeowners here don't, because clay tile is central to Kensington's Spanish revival look and switching materials stands out on a block built around architectural consistency. A lift-and-relay is usually cheaper than people expect once they compare it to full tile replacement, so most owners end up staying with tile anyway.
Some of my roof tiles are cracked or missing, can you match them?
Yes. Matching profile and color on Kensington's clay tile is a routine part of this work, whether that means sourcing reclaimed tile that matches an older roof or a close modern match. The roofers we match you with know how to blend replacement tile in so it doesn't stand out against the original.
How do you find where a roof leak is coming from?
We start where the water shows inside, then move uphill to all penetrations within 12 feet: pipe boots, vent stacks, chimney flashing, skylights. A moisture meter confirms active moisture in the decking. We check every detail physically rather than guessing from below. The source is usually a failed rubber gasket, cracked mortar, or corroded flashing, not a hole in the field of the roof.
