About This Service
Caps don't last forever — galvanized units rust through, mesh clogs and tears, wind loosens mounts, and hail flattens hoods. Replacing a failing cap is quick, inexpensive insurance for everything below it, because every cap failure becomes a water or wildlife problem next.
We remove the old unit, check the flue tile and crown while we're up there, and install a properly sized stainless or copper replacement with wind-rated anchoring. If your old cap failed young, we'll tell you why so the next one doesn't.
Signs You Need Chimney Cap Replacement
- Visible rust streaks running from the cap onto the crown
- The cap rattles, sits crooked, or has shifted
- Mesh torn, missing, or packed solid with creosote
- Hail-dented hood no longer shedding water properly
How Installation Day Goes
Flue and crown measured and checked — a cap on a damaged crown is a bandage, and we'll tell you.
The correct-size unit is fitted and mechanically anchored (never friction-fit) for Colorado wind.
Mesh, clearances, and draft are verified with the appliance where applicable.
Old hardware is hauled away and the roof is left exactly as we found it.
Why It Matters for Safety
An open flue admits rain, animals, and debris — and lets embers exit. In Colorado's fire-conscious communities, spark-arresting mesh on wood-burning flues protects your roof and your neighbors', which is why we treat proper capping as safety equipment, not an accessory.
Maintenance Tips From Our Technicians
- Check the cap visually after major wind events — from the ground is fine.
- Wood burners: have the mesh cleaned with each sweep; it cakes faster than you'd think.
- Rust streaks below the cap mean it's talking to you — replace before it fails.
- After roof work, verify the cap was reinstalled properly; roofers move them.

Frequently Asked Questions
My cap keeps blowing off — what's wrong?
Almost always a friction-fit or undersized mount. Replacement caps we install bolt mechanically to the flue tile or crown, which is what Front Range and mountain wind actually requires.
Can a clogged cap cause smoking problems?
Yes — spark mesh gradually cakes with creosote, especially on wood-burning flues, and a half-blocked cap chokes draft. If your fireplace suddenly smokes, the cap screen is one of the first things we check.
Are you licensed and insured?
Fully. Donovan Chimney & Fireplace carries the licensing and insurance this work requires, and certificates are available on request — something we recommend asking of any company that climbs on your roof.
