Yer yella! Razz

I am too. I have not problem getting up on the roof or being up on the roof. It's the getting down part that scares the crap out of me these days. Turning around backwards at the edge and swinging a foot around trying to find a rung on the ladder before I lose my balance and.... No thanks. If I can't rope up, I'm not up there anymore.

Damn right I’m yella! About rambling around roofs during winter, at least.

Well, now I’ve got water stains on the drywall in the upstairs bedroom, right where the chimney stack is on the outside of the house.

Guess this means I will be calling another man in addition to the roofing repair man…

Is there any way you can safely get into the attic and inspect the interface between the roof and chimney?

In another vein I believed you mentioned someone saying that the brick was porous and that could be the cause of the leaking and you thought that was crazy. I’m here to tell you that a porous brick is a real thing. Depending on the brick itself it can absorb a significant amount of water. As a standard practice our roofer would always apply water seal to the brick when he flashed the chimneys on our houses. The issue is even more pronounced with stone chimneys.

I don’t recall stating porous brick is “crazy.”


I’m firmly convinced of the porosity of brick, actually.


Now, slight water stains on the drywall in the fireplace room… oh joy,


Thanks to alll for their advice. Sig Forum never disappoints!

If you can get up there or have someone go up there or get a drone to take a pic, it may look like this. We had to have ours redone as the crown was cracked:

With that much snow and ice this year, and, the amount of water and ceiling damage it may be more than the crown, likely the flashing around it, if the snow is higher than the top of the flashing it can run down the back side if it wasn't sealed properly, or, the seal is older and deteriorated.

I guess it's better than when my parents woke up to smoke in the house and found the floor under the hearth on fire where ashes had got through a crack between the box bricks and the hearth. Started a fire in the joist area, fire department had to tear out the basement ceiling where the fireplace continued down to another fireplace in the basement.
