Torrance Roof Pros provides professional chimney flashing in Torrance, CA for residential and commercial properties across the South Bay. Step flashing is a slope-dependent detail. Each piece works because the piece below it sits far enough down the roof to be out of the water. Flatten the plane and that geometry collapses, which is why chimneys in these tracts leak no matter how much sealant goes on them.
Two chimney types dominate the local housing stock. Short masonry stacks near a ridge on the older ranch tracts, and metal B-vents rising through a low plane where a wall furnace or a raised-hearth fireplace was originally fitted. Both leak in the same place, the up-slope face, where the water the field delivers has to be split and sent around an obstruction that was never designed to divert it.
On a plane under about 3-in-12 the correct detail is not step flashing at all. It is a one-piece soldered or welded pan with a minimum four-inch upstand on all sides, taken over the field on the down-slope side and under the membrane above, with a cricket framed in behind the stack whenever the chimney measures wider than roughly thirty inches across the flow.
The top edge gets a reglet. We cut a groove into the mortar joint, fold the counterflashing into it, and secure it with lead wedges and a suitable sealant, so water running down the masonry face is intercepted by metal rather than by a bead run along the outside of a brick. Surface-mounted counterflashing on a shallow roof is a temporary fix that people end up paying for twice.
Metal flues need the same discipline in a simpler shape. A proper storm collar and a flashing cone lapped correctly into the field beats a tube of mastic every single time, and on a low-slope plane we run a self-adhered membrane collar up the pipe underneath the metal, so there are two lines of defense at the penetration rather than one.
We do not sell chimney repairs we cannot stand behind. If the crown is cracked through, the brick is spalling badly, or the stack is out of plumb, new flashing will only move the leak somewhere else. We will say so, tell you plainly that it is a masonry job first, and come back to do the roof side once the structure is sound. The roof detail is only as good as the masonry it lands on.
Our licensed and insured team brings the right materials and equipment to every job — 2-in-12 minimum shingle slope, double underlayment lapped 19 inches, 60-mil mechanically attached TPO, two-ply SBS modified bitumen cap sheet, mechanically-seamed double-lock metal panels, self-adhered high-temperature underlayment — and backs the work with a written workmanship warranty. We serve Torrance and nearby communities including Redondo Beach, Lomita, Gardena, Carson.

Materials, equipment and how we do chimney flashing
The difference between chimney flashing that lasts and chimney flashing that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with 2-in-12 minimum shingle slope, double underlayment lapped 19 inches, 60-mil mechanically attached TPO, two-ply SBS modified bitumen cap sheet, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Torrance job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in the South Bay means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
