Medford OR Roof Pros provides professional chimney flashing in Medford, OR for residential and commercial properties across the Rogue Valley. A chimney is four separate flashing details pretending to be one, and it leaks more often than every other penetration on a Medford roof combined. Base apron below, step flashing woven into the courses on both sides, counterflashing let into the masonry, and a saddle behind a wide stack.
Southern Oregon still burns a lot of wood, and that changes what we find. An actively used masonry stack cycles hot and cold through the whole wet season, the crown cracks, and water enters at the top and shows up on a ceiling six feet from the chimney. Before we quote flashing we check the crown, the cap and the mortar, because reflashing a chimney that leaks through its own crown solves nothing.
The counterflashing is the detail worth insisting on. Sealant smeared onto the face of the brick is not counterflashing. It is a two-year product, and in a valley with this much surface heat and this much ultraviolet it is often less. Metal has to be let into a sawn reglet in the mortar joint, then folded and locked, so that the water has no path even after every bead on the roof has failed.
We build a saddle behind any chimney wider than about thirty inches whether or not the code triggers one at your dimension, because the alternative is a flat shelf of shingles collecting fir needles and oak leaves against the masonry for five dry months and then holding water against it for four wet ones. It costs about a day, and it is the single most common thing missing on a Rogue Valley chimney.
There is an underwriting angle here too, and it is worth knowing. A chimney is the most legible defect on a roof from the air. Rusted flashing, a leaning stack, a missing cap and staining down the slope below it are all visible in aerial imagery, and they read as neglect for the whole property rather than as one detail. Fixing a chimney is cheap insurance in the literal sense.
We reflash in twenty-six gauge galvanized or in copper where the house deserves it, we photograph the reglet cut and the step laps before the shingles go back, and we hand you the photographs. If the chimney is disused and structurally tired, we will price removal and a framed-in patch alongside the repair, because that is often the better answer. You will never see that detail again once the roof goes back on.
Our licensed and insured team brings the right materials and equipment to every job — a Class A assembly listing carried by number onto the invoice, high-temperature self-adhered membrane specified for a hot deck, rigid baffles fitted so blown insulation cannot drift over the intake, a photographed fastener pattern logged before the underlayment goes down, an open valley pan hemmed on both edges and set over rosin, sealant strips given a warm night to bond ahead of wind season — and backs the work with a written workmanship warranty. We serve Medford and nearby communities including Ashland, Central Point, Grants Pass, Eagle Point.

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 a Class A assembly listing carried by number onto the invoice, high-temperature self-adhered membrane specified for a hot deck, rigid baffles fitted so blown insulation cannot drift over the intake, a photographed fastener pattern logged before the underlayment goes down, 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 Medford 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 Rogue Valley means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Medford Chooses Medford OR Roof Pros
- ✓We establish which building department your address answers to before we quote, because two jurisdictions near here adopted the wildfire code section and two did not
- ✓We tell you the thing nobody selling roofs in this valley volunteers: the state hazard map was voided in July 2025, so no public rule sets the covering class on your re-roof
- ✓Before you buy a single fire-hardening line, we send you to your carrier for the written credit schedule Oregon law entitles you to, and we strike whatever it does not pay for
- ✓Every job closes with dated photographs of each plane and the assembly listing number, because what most often costs a policy here is an aerial image the owner never saw

Quality here is not a matter of opinion — it is written down.

If a contractor cannot tell you which standard a detail comes from, that is worth asking about before you sign.
