Portland ME Roof Pros provides professional chimney flashing in Portland, ME for residential and commercial properties across southern Maine. Chimney flashing is the single most common source of a leak we are called to in this city, and it is almost always because somebody solved it once with a tube of sealant. Sealant against masonry lasts about two winters and gets sold as forever.
Done right, two independent metal systems sit there without ever being fixed to one another. Step flashing interleaved course by course, fastened down into the deck and never into brick. Counterflashing above it, cut into a raked mortar joint, folded, wedged with lead-free anchors and repointed. The two overlap and slide independently, which is the entire point, because a chimney and a roof move on different schedules and anything rigid between them tears.
Portland's chimneys make this harder than average. Many were built for coal or oil and are wide, and any masonry mass over about thirty inches across the slope needs a cricket behind it to divert water around rather than into the upslope joint. A chimney without one collects debris on its high side, holds moisture there through the winter, and rots the deck under it while the flashing itself looks perfect.
The frame this site works from turns up here too. Where a chimney passes through a rake return or a painted wood cricket, or where the counterflashing has to be let into a chimney chase clad in painted clapboard rather than brick, the flashing job crosses into painted surface and the scope changes with it. We measure that at the estimate and never after.
On metal we use aluminum or stainless. We do not use lead flashing on residential work here even though it is traditional, workable and long-lived, because we are not going to explain to a homeowner why the lead-safe contractor installed lead above their bedroom window. Copper where the building warrants it and the budget allows.
What we do not do on this page is tell you what to do with the chimney itself. Whether a disused flue should be rebuilt, capped or removed is a masonry and combustion question, and it belongs to a mason and, if anything still vents into it, a licensed heating contractor. We flash what is there, and we say plainly when the honest answer starts with somebody else's trade instead of ours.
Our licensed and insured team brings the right materials and equipment to every job — self-adhered ice barrier membrane at eaves and in every valley, over-fascia intake vents slotted through sheathing instead of painted soffit, board sheathing overlay panel where plank gaps outrun a fastener's grip, concealed-clip standing seam panel in a Kynar finish, counterflashing let into a raked mortar joint and repointed, soldered stainless liners fitted inside built-in cornice troughs — and backs the work with a written workmanship warranty. We serve Portland and nearby communities including South Portland, Westbrook, Scarborough, Gorham.

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 self-adhered ice barrier membrane at eaves and in every valley, over-fascia intake vents slotted through sheathing instead of painted soffit, board sheathing overlay panel where plank gaps outrun a fastener's grip, concealed-clip standing seam panel in a Kynar finish, 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 Portland 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 southern Maine means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
