Crown first, cap second
A cap holds only as well as what it is fastened to. An outside-mount cover anchors into the crown, and a single-flue cap grips a tile that the crown holds in position.
When the crown under a cap in O'Neil is cracked, crumbling or has pulled away from the tile, the concrete is dealt with before any new cap is mounted. We price the crown and the cap as separate lines, so each can be seen on its own, and we book them in the order that keeps a new cap from sitting on a failing base. A cap bolted to broken concrete loosens as the concrete around its anchors breaks up. Pick a time for our cap pros to come to O'Neil; the number is (904) 920-5495.
O'Neil lies within Nassau County. O'Neil is near the coast without touching it.

From tile measure to fastened cap in O'Neil
-
Tiles measured on the roof
Each flue tile is measured inside and out, along with its height above the crown.
-
Cap style and metal chosen
Slip-in, band-mount or full-crown, in a metal suited to the roof, with a screen that meets the Florida code.
-
Flue cleared, cap fastened
Any nest or debris comes out of the flue, then the cap is set and fastened for wind.
-
Fit and screen checked
We check that the cap sits square, the hood height matches the chart and the screen comes off for the sweep.
Cap metal close to the coast
O'Neil is near the ocean. Salt still settles on caps there, and a galvanized cap loses its zinc coating sooner than it would farther inland.
So for O'Neil chimneys our default is stainless steel, and a marine grade is offered when the chimney faces the ocean wind.

What to look for from the yard after a storm
Binoculars and a clear day are enough for a first look after bad weather. Stand where you can see the top of the chimney and check four things. Is the cap still square on the tile, or leaning? Is the lid flat, or lifted at one corner? Is the screen continuous all the way around, or is there a dark gap? Are there fresh rust streaks, screws or metal pieces on the roof below?
Any one of those is a reason to call before the next storm, and none of them needs you on a ladder. If you can, take note of which side of the chimney the damage faces, since it helps us plan the visit.
Why the old cap is not the pattern
Ordering a replacement to match the cap that came off is tempting. The trouble is that the old cap may not have fit in the first place. Caps sized a step too small get forced over a tile and crack it; caps a step too large sit loose and walk off in wind. Some were fitted before the crown was redone and no longer match the tile height at all.
So we measure the tile and the crown as they are today and size from the maker's chart, and the old cap leaves the roof with its fasteners. The measurements stay on file for whoever services the chimney next.
Cap metal where salt reaches the roof
Salt carried on the wind settles on a cap and draws moisture to it, and chloride salt attacks metal that would last for years further inland. Some cap makers offer a Type 316 stainless line, sold as marine grade, for sites near salt water, since the molybdenum alloyed into 316 resists chloride pitting better than the common grade. A stainless-steel guide from the International Molybdenum Association adds that sheltered, rain-shadowed crevices hold salt longer than surfaces rain rinses, and a cap screen is full of such crevices. We follow the maker's grade guidance for the exposure, name the grade, and suggest rinsing the cap when the chimney is serviced.
What sets the cap on your estimate
- Inside and outside size of each flue tile, measured on the roof
- Height of each tile above the crown, and whether it can hold a cap
- Anything near the chimney on the roof that belongs to a roofer
- Clean-up of old metal, screws and debris from the roof and yard
Cap questions we hear in O'Neil
Do you replace chimney caps in O'Neil?
We do. Call or send the form, tell us what you see at the top of the chimney, and we set a time to measure in O'Neil.
Should the replacement cap match the old one's size?
Only if the old one fit. We size from the tile and crown as they are now, using the maker's chart, and the estimate lists the measurements.
