The chimney crown is widely considered the first line of defense against moisture. Because it is located at the top of the chimney, the crown is subject to the worst of the outdoor elements. When built correctly, the crown works like an umbrella, protecting the chimney stack from streaming water. The crown also keeps water from getting between the chimney flue and the chimney exterior.
Chimney crowns are much more vulnerable to deterioration than masonry, but keeping watch over it is difficult, since you have to be on the roof to check its condition. Our chimney experts always inspect the chimney crown during a chimney inspection.
Chimney Crown Waterproofing
If a chimney crown has minimal damage, it is often sufficient to use high bond patching material to fill the cracks. We recommend that homeowners approve a protective layer of waterproofing sealant being added. The material used keeps water out while allowing the chimney surface to breathe. Adding waterproofing to the entire chimney can cut chimney maintenance costs by preventing moisture from getting in and causing damage.
Chimney Crown Rebuild
A chimney crown cannot always be patched. There are times when a chimney crown teardown and rebuild is necessary, such as when it begins showing significant evidence of aging. If there are broken and missing pieces, a chimney crown has lost its structural integrity.
One of the problems with hiring someone for chimney repair who isn’t an expert is that the incorrect materials might be used, which can be the case with chimney crown rebuilds. It’s not unusual for an inexperienced individual to “repair” a chimney crown by using mortar mix. This material isn’t weather resistant enough to protect the chimney crown for long.
Our chimney experts at Four Seasons Fireplace & Chimney typically use cement for chimney crowns. Other options include cast-in-place concrete or pre-cast concrete crowns with steel reinforcement. Stone and metal can also be used. Most importantly, the chimney crown needs to be water-tight and weather-resistant. When built, the chimney crown should have a slight slant from the center, so that water is diverted away from the chimney instead of pooling up.
