Pieces of crown on the roof

Chunks of gray concrete or mortar on the roof, in the gutter or on the ground below the chimney most likely came from the top of the stack. Their shape tells us something: thin, feathered flakes point to a mortar wash breaking up at its edges, while thicker blocks suggest a cast crown cracking through.

If you find pieces around your Sunbeam house, keep one to show us, stay off the roof, and keep people clear of the area below the chimney. Loose pieces still on the crown can fall in the next wind, and removing them safely is part of the first visit. Cracks on top of your Sunbeam chimney? Our masons inspect crowns for free, so call (904) 920-5495.

Sunbeam sits in Duval County. Sunbeam does not reach the coast.

Map, prep, coat or pour, cure

Crack map from the roof
We identify the type of top and sketch each crack with its width, so the choice between coating and recasting is based on what is there.
Prep for coating or removal
A sound crown is cleaned and its wider cracks filled; a failed one is broken out down to sound brick.
Coat, or form and pour
The coating is brushed on in dry weather, or new concrete goes into forms with an overhang, a drip groove and reinforcement.
Cure, seal and refit the cap
The bond break at each flue is sealed, the concrete cures under cover, and the cap goes back on.

What cracks crowns in Sunbeam

Crowns in Sunbeam sit inland, away from most of the salt. Water and heat do the damage. Rain sits on a flat top and finds each hairline crack, and the flue tile expands against a crown poured tight around it.

The repair answers both: slope and a drip edge for the water, a sealed bond break at the flue for the heat.

Hairline, open and through cracks

Crown cracks come in three broad kinds. Hairline cracks are surface lines you can see but not fit a fingernail into. Open cracks have width and depth, and water pools in them. Through cracks run the full thickness of the slab, so a piece moves when pressed or water drains straight into the chimney.

Hairline cracks on a sound crown are the case for a coating. Open cracks need filling first, and a coating after. Through cracks, especially several of them, mean the crown has become separate pieces, and the reliable repair is a new crown. The crack map records which kind each crack is.

What goes into the bond break at the flue

The bond break is the flexible joint between the crown and each flue tile. It lets the tile grow with heat without pushing on the concrete. The code calls for it to be caulked, following ASTM C1283, and the BIA detail shows a backer rod with sealant over it.

In practice we wrap the tile with a compressible material before the concrete is placed, then rake the top back and fill it with a primed backer and a sealant suited to heat and weather. The finished joint stays flexible. A crown poured tight against the tile, with no gap at all, is the fault this detail exists to prevent.

Keeping new concrete damp while it cures

Concrete gains strength through a chemical reaction that needs water, and a crown on a sunny, breezy roof dries out fast. If the surface dries too early, it can craze and dust, and the crown ends up weaker than its mix should give.

After the pour, the crown is covered and kept damp for the curing period the mix calls for, and it is protected from rain until it has set. The forms come off once the concrete can hold its edges. Those steps are why a crown recast can take more than one visit, and you know in advance when each one happens.

Coat or recast, and the reasons

Coating product class and the data sheet's weather window
Top courses of brick relaid before the new crown goes on
Chimney cap removal and reinstallation, with how it is fastened
Rain protection for fresh concrete while it sets

Crown repair questions from Sunbeam

Does crown work mean the chimney cap comes off?

For a recast, yes. For a coating, it depends on how the cap is mounted. The estimate says which applies to your chimney.

Can a drip edge be added to my existing crown?

Not in a way that lasts. A drip edge has to be formed into the underside of an overhang, and a crown without an overhang has nowhere to put one. The fix is a new crown formed wider than the chimney.
