What chimney cap installation actually involves

An open flue here collects whatever the sky and the trees send down. Seattle's windstorm analysis puts the peninsula on its short list of districts most open to wind damage, and gives the reason: few parts of the city are as heavily forested. Wikipedia notes that one-third of Seattle's green space and urban forest lies on the peninsula. Needles, leaves and twigs fall straight into an uncapped flue, and so does the rain of a wet season lasting over half the calendar. We measure the flue tile or the crown, choose a cap with the correct open area, and fasten it mechanically so that wind cannot lift it.

The side facing Puget Sound gets the weather first. High winds and tides on the exposed western side are the reason Wikipedia gives for the 1851 landing party judging it unfit for a major city; most of them moved across Elliott Bay. For a house along that shore or on the crest above it, we favor a low-profile cap on a bolted base, and we look at the fasteners again at each sweep.

What's included

  • Measurement of each flue tile, or of the whole crown for a multi-flue cap
  • A stainless steel cap with mesh sides, sized so the opening under the lid is not restricted
  • Mechanical fastening to the tile or the crown, never adhesive alone
  • A check of the crown and top courses while we are on the roof
  • Photos of the flue top as found and as left

Why it matters

The Seattle Residential Code treats the opening under a cap as part of the flue. Beneath a rain cap, the net open area has to equal no less than four times the flue outlet (R1003.9.3). Where a spark arrestor is fitted, its screen must stop a 1/2-inch sphere while letting a 3/8-inch one pass, resist heat and corrosion as well as 24-gage stainless steel does, and come off for cleaning (R1003.9.2). A cap chosen by eye at a hardware store can miss both points.

Water entering the flue soaks soot into a paste, rusts the damper and wets the smoke shelf; a nest or a wad of leaves blocks the draft and turns smoke and carbon monoxide back toward the room. A cap also has to stay put. Seattle's hazard analysis notes that sheltered as Puget Sound is, sustained winds there can reach 60 to 70 mph and gusts 90, and that hills and ridges speed the wind up. West Seattle is two glacially shaped ridges, by the Seattle Landslide Study's description, so every cap we install is fastened with wind in mind.

How it works

What to expect with chimney cap installation

  1. 1

    Measure

    Flue dimensions, how far the tile stands proud of the crown, and how many flues there are, decide the model.

  2. 2

    Check the seat

    A cracked crown or a loose top tile is reported first; a cap needs something sound to grip.

  3. 3

    Fit and fasten

    The cap is set level and secured with screws or anchor bolts.

  4. 4

    Test

    We confirm that the damper opens and the flue draws with the cap in place.

  • Rust stains running down from the flue top

Chimney Cap Installation — common questions

What will an installed chimney cap cost me?

Cap installation runs $235–$850 with us. One ordinary flue is the low end; a custom size, or a single cap spanning several flues, is the high end.

How do I know whether my chimney already has a cap?

From the ground, look for a lid standing on legs or mesh above the flue. A bare clay tile ending flush at the top means no cap. A metal factory-built chimney has its own listed termination, which is a different part; if that is damaged, it has to be replaced with the manufacturer's component.

Will a cap hurt the draft?

Not when it is sized correctly, which is the purpose of the code's four-times-the-outlet rule. Mesh that is too fine or a lid set too low is what chokes a flue.

Can a cap stop downdrafts on windy days?

A standard cap helps a little by shielding the opening. Persistent wind-driven downdraft calls for a cap designed for it, and sometimes the cause is the chimney's height relative to the roof or to nearby trees, which we check first.

Does the mesh need cleaning?

Yes. Burning damp wood can clog the mesh with soot and creosote within a single season. We brush it at each sweep, and the code requires an arrestor screen to be removable for exactly that purpose.
