Question
QUESTION: i recently repaired a wooden chimney[rebuilt it] but after i finished i realized that it was out of square and the old chase cover no longer fit[it was short in one corner].i sort of reformed that corner but it still is short.I then used some caulking and black chimney patch and some self sticking flashing to cover and prevent leaks.My question is: is there a chance that the cover will get hot and start a fire?The cover is only attached to the flue as it projects thru the cover.Can i make a repair to the cover say with a piece of metal attached with rivets?

ANSWER: Hello Mickey, a Chase cover just covers the top of the chase (box you rebuilt) and keeps the water and stuff out, you could have it remade if you have the exact measurements (do a search for custom chase covers) or try your local sheet metal shot pricing may be great so shop

QUESTION: thankyou for very much for your answer.Does the chase cover get hot or does the stack which is insulated stop the transfer of heat? Also can i make a repair to the cover. the cover is only connected at the neck of the stack which projects thru it?the reason i ask is because i have made repairs to it with some flashing caulked with roof cement and latex.It would appear that that's not a fire hazard,would you agree? also can i make additional repair using rivets to add a piece of sheet metal in lieu of buying a new one

Answer
Welcome back Mickey, the pipe needs 2" to combustibles,  and Caulk, roof cement and latex will all burn so they need to be 2" from that pipe. It might be easier and safer to just buy a new one, repairs are just that , fix it right and feel safe.
