Once again, purchase a proper chimney cover to your chimney’s size and specifications. If unsure, ask any trained professional at the store. Fix cracks during dry months.
Chimney caps or covers also protect certain unwanted guests such as night-time refugees in the form of animals or even people. Have you ever considered this thought? Many recent news reports, in fact, have found escaped convicts or wanted people dead or hiding within chimneys. It’s a sad reality that our current world faces.
Any animals that are blocked out through a strong seal or cap cover must find another place to make their nests and build their homes. Flashing metal gaps within the line of any shingled roof may lie in the sheet metal. Feel with your hands for moisture or gap openings.
