I live in an 100 year old house in Michigan. I have suspicions that the flashing around my chimney is leaking as the plaster in the ceiling directly below the chimney & roof point is getting soft and the paint is peeling. I intend on doing it the right way and replacing the flashing and/or ensure the seal is in good shape. The problem is that its winter and I cannot safely get up onto the roof to do that. Are there products that I could apply from the attic to help block the water from coming in until I can fix this the proper way?

No. That would be like sealing the bottom side of a sponge--moisture will travel through it to emerge in other areas.
You can probably accomplish the repair even in winter. A water hose will quickly melt snow and ice from the areas you need to access, or use scaffolding and other hardware to work over it.

Okay I checked the weather and this weekend its supposed to be above freezing and their isnt any ice or snow up there right now. I am thinking of using this sealant on the flashing. Have you any experience with products such as these and do you think it would suffice? homedepot.com/p/… Commented Jan 4, 2019 at 19:09

There are products designed to be installed in the wet. Talk to your local contractor supply shop or read labels. I won't have a specific recommendation. Commented Jan 4, 2019 at 19:10
