Kensington is not a typical roofing market. The village banned commercial buildings in 1915, which means almost every roof we touch here sits on an owner-built or incrementally expanded home, not a production build. That changes how we approach Roof Repair: we inspect first, write allowances into the contract, and price every surprise on paper before we touch it.

Why Brennan Roofing Is Kensington’s Preferred Roof Repair Company

Kensington homeowners tend to know their houses. Many have lived here through enough winters to understand that water moves downhill and valleys fail first. They call us because we talk about roofs the same way they do, in plain terms: flashing, decking, underlayment, drip edge, and what each one actually does.

Every technician who arrives in Kensington is background-checked, uniformed, and works under the Garrison Standard. That means a written price in your hand before any work begins, no exceptions. If the price moves at the door, that’s not our crew. We do not run jobs that way, and we put that in writing.

One thing that matters here more than in flatter parts of the Bay Area: we send people who understand reverse-slope drainage and unrecorded additions. A roofer who has never worked a Kensington hillside might misread why water is pooling at a low-slope valley. We have seen it enough to check the upslope neighbor’s roofline before we quote a downhill repair.

Our Kensington customers can reach a live person at (361) 320-9467 any hour. No voicemail tree. No callback queue. When a January storm opens a leak into a walk-out basement at 2 a.m., someone answers.

Metal Roof Repair in Kensington

Metal Roof Repair in Kensington usually falls between $600 and $2,400 depending on the panel profile, the extent of fastener failure, and whether we are replacing panels or re-detailing seams. Many older Kensington homes never had metal roofs originally; the standing-seam or corrugated panels you see were often added during a later remodel, sometimes over original skip sheathing that was never re-decked.

Fastener and Panel Work

On exposed-fastener metal roofs, especially on north-facing slopes that stay damp under fog and tree cover, the rubber washers on screws harden and crack. Water wicks in around the fastener, rusts the panel, and drips onto whatever is below. We replace the fasteners, re-seat panels, and treat rust spots before they open into holes.

Seam and Flashing Re-Detail

Standing-seam panels rarely leak at the flat metal itself. They fail at transitions: ridge caps, valley intersections, pipe boots, and the edges where a later addition meets an original roof plane. On a Kensington hillside, that intersection carries more water than the panel run above it ever sees. We pull the old sealant, re-bed the seam, and set new closures so the metal sheds water instead of holding it.

Commercial Roof Repair in Kensington

Commercial Roof Repair in Kensington is a small but real category, mostly low-slope built-up or modified bitumen roofs on the few non-residential structures the village allows, plus flat roof sections on mixed-use properties. Expect $800 to $3,000 for a targeted repair, and more for a full membrane section replacement. Kensington’s 1915 ban on commercial buildings means there is very little large-format commercial square footage here, which is exactly why we do not treat it as an afterthought.

Flat Roof Patch and Membrane Work

A flat roof on a Kensington building takes rain differently than a pitched shingle roof. Water ponds, finds a seam, and works its way in slowly. By the time it shows on a ceiling, the membrane has usually been compromised for weeks. We locate the true breach, cut back to sound decking, and patch with compatible material rather than layering tar over a wet core.

Drainage and Scupper Repair

On low-slope roofs, the drains and scuppers fail before the field membrane does. Leaves from Kensington’s tree cover plug the outlets, water backs up, and the head pressure pushes through seams that were never designed to hold standing water. We clear the drainage path, repair the surrounding membrane, and re-secure the metal at the scupper so water exits the roof the way it was meant to.

Trusted Brands We Service in Kensington

We work on whatever is already on the roof, but when a Kensington repair calls for new material, we install from manufacturers we know hold up on foggy, moss-prone hillsides. That includes GAF architectural shingles, CertainTeed underlayment and ice and water shield, and Owens Corning ridge and starter lines. We keep common color profiles and accessory stock available for quick turnaround on Kensington jobs, so a repair does not stall waiting on a distributor. If your roof carries a warranty from one of these lines, we handle the repair in a way that does not void it.

Common Roof Repair Problems We See in Kensington Homes

• Low-slope valley flashing failures on the downhill side. During heavy winter rains, downhill-side valleys carry more water than the original 1910 – 1940 build ever anticipated. Often an upslope neighbor’s unrecorded addition has redirected stormwater onto that valley, and the original flashing simply cannot keep up.
• Moss on north-facing shaded slopes. Kensington’s fog cycle keeps north slopes damp nearly year-round. Moss holds moisture against underlayment and decking, and aggressive scraping to remove it rips granules off shingles, destroying the wind rating before the roof’s life is up.
• Rotted skip sheathing beneath otherwise intact shingles. Original skip sheathing, common on brown-shingle homes, leaves gaps between boards. Years of condensation and slow underlayment failure rot those boards from above. By the time a leak shows inside, the decking under the shingles is often gone.
• Unrecorded additions changing roof geometry. Kensington’s owner-built history means many roofs carry planes and valleys that were never on any permit drawing. When we open up one of these intersections, we often find undersized framing or missing flashing behind the visible surface.
