Bellingham Roof Pros provides professional chimney flashing in Bellingham, WA for residential and commercial properties across the Nooksack lowland and north Skagit County. Chimney leaks in Bellingham are overwhelmingly an upslope problem, and the winter sun angle explains why. A stack casts its shadow to the north of itself, which on most roofs means straight up the slope and directly onto the flashing details that already work hardest.
With the December sun sitting under eighteen degrees, anything vertical throws a shadow roughly three times its own height. A four-foot stack therefore holds about twelve feet of roof behind it in shade through the entire season, and that shaded band is exactly where the back pan, the saddle and the upper step flashing live. The hardest detail on the roof is also the one that never dries.
Which is why we do not accept a plain back pan on anything except the narrowest stack, whatever the original builder got away with. Any chimney wider than about thirty inches gets a framed saddle behind it, sheathed and flashed and sized to divert water and debris around both sides, rather than asking a single piece of bent metal to hold back a whole slope of runoff and a winter of fir needles.
The rest is standard work done without shortcuts, because the shaded band gives no margin for a detail that is only nearly right. Individual step flashings woven course by course rather than one continuous L. Two-piece counterflashing let into a sawn joint and sealed with polyurethane, never face-nailed to the brick. Self-adhered membrane turned up the masonry behind everything metal.
On metal chase chimneys the failure point moves but the logic does not. Chase covers built with no cross-slope pond on the shaded side, corrode from the inside out and drop water down the chase into the framing. A flat cover on a Bellingham house is a leak with a schedule attached to it, and replacing it with a sloped, cross-broken cover is genuinely cheap insurance.
Before we quote flashing, we check whether the masonry itself is the source. Spalled brick, an open crown or missing mortar on the shaded face will keep leaking after perfect flashing work, and we would rather send you to a mason first than take money for the wrong repair. That call costs you nothing and saves good flashing work from being blamed for a problem it could never have solved.
Our licensed and insured team brings the right materials and equipment to every job — compass bearings shot on every plane before a price is written, winter solar altitude worked out plane by plane, high-temperature synthetic underlayment across the shaded planes, furring strips holding a drained airspace under steel panels, tab sealing done by hand on planes that have lost the sun, eight-penny ring-shank nailing into new plywood decking — and backs the work with a written workmanship warranty. We serve Bellingham and nearby communities including Ferndale, Lynden, Mount Vernon, Anacortes.

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 compass bearings shot on every plane before a price is written, winter solar altitude worked out plane by plane, high-temperature synthetic underlayment across the shaded planes, furring strips holding a drained airspace under steel panels, 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 Bellingham 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 Nooksack lowland and north Skagit County means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Bellingham Chooses Bellingham Roof Pros
- ✓We shoot a compass bearing on every plane of your roof and write it on the diagram, because at 48.75 degrees north the bearing answers more questions than the shingle brand does.
- ✓We will not put a skylight on a north-facing plane in this city, and we will show you the winter sun angle rather than argue about it.
- ✓We do not sell coatings for north-facing roofs here. A film that needs warmth to cure and sunlight to stay dry has nothing to work with on that side of a Bellingham building.
- ✓Steel over a shaded plane goes down on furring with a drained airspace beneath it, never flat to the deck, because a cold panel condenses on its underside long before it ever leaks.
The standards behind chimney flashing
Quality here is not a matter of opinion — it is written down. The chimney flashing work we do in Bellingham follows published industry standards: NRCA publishes the Roofing Manual, the industry's reference for details and slope minimums, and Asphalt Roofing Manufacturers Association sets the shingle application and ventilation guidance the warranties reference. If a contractor cannot tell you which standard a detail comes from, that is worth asking about before you sign.
Every chimney flashing project in Bellingham gets the same attention, whether it is a single room or a full commercial job. We show up on schedule, keep the site clean, and stand behind the work — the estimate is free and there is no pressure.
