Three shots showing roof ,looking down and looking up from cleanout.
Please note the three bricks near the top and under the top section of clay tile liner.
They seem to be there to support the final section insert for some reason.
Not the first time I have seen this and wondering why it is done.
Besides writing the Chimney needs to be Inspected and Video Scanned by a Licensed Chimney Sweep it also has unknown objects in the flue which should be determined by the professional doing the Chimney Inspection-Video Scan-Cleaning prior to the end of their Inspection Contingency Period.
I will sit on this one for a day and see if anyone knows why they do this.
Have seen it several times and I think it is intentional .(note different color from outside brick)
Perhaps I’m wrong.
I agree ,because the chimney is not lined all the way through.
I stuck my arm in and took the shot in bright sunlight ,so this was not really looked at till later.
Sometimes pictures can fool you.
Here is a shot looking down the waste stack for instance.
First glance you think waste stack is blocked but actually there is a 90 in the attic.
Since the gap is somewhere near the roof line or above (chimney) ,would you say the biggest concern is simple premature brick and mortar deterioration from the mid efficiency furnace and water heater that are attached…?
They used the bricks as spacers to extend the flue. That’s why the exterior brick/mortar is deteriorated in that area. As far as chimney caps, I never had caps on my chimney until I got a call from my neighbor to come look at his raccoon family living in his chimney.
