How to Repair Metal Chimney Caps How to Repair Metal Chimney Caps
Metal chimney caps are visible features at the exterior end of most chimneys. They are important in their capacity as roofs for the chimneys. Whether they are made out of stainless steel or copper, they are still susceptible to damage, like shrinkage, cracks or dents. Repairing these defects does not always require the involvement of a professional, and in fact can be done quite easily.
Step1 - Straighten the Dents
This is the most common type of damage to metal caps. Use a pair of pliers to straighten out the dents that may have formed on your cap.
Step 2 - Recap the Chimney
If your metal cap has cracked beyond repair you can easily recap the chimney by layering a new metal cap over the old one. Simply take the measurements of your old cap and cut or purchase your new cap according to these specifications. Use caulk or a metal adhesive to paste it over the old one.
Step 3 - Tighten the Screws
The screws of your chimney cap may simply have loosened over time or from exposure to the elements. Use a screwdriver or a hammer to tighten them back into place.
If your cap only required brief attention, don’t forget to clean out the soot or any other debris that may have accumulated underneath the caps before you replace them over the chimney.
