Just joined the forum a few days ago. Have been lurking and learning from everyone for more than a year. Burned the entire season last year. Had a sweep come out last month. I was not home when he did it, but my wife said he never went on the roof and did all the work from the inside. He obviously didn't clean the cap. My chimney protrudes about 10ft. from a very steeply pitched roof. The cap would be very difficult to remove. Question: Would I be safe to only clean the cap every-other-year?
