Rotting roof rafter repair help
Hi, not sure what to do here. The roof rafter is up against the chimney breast and as you can see water has rotted the rafter and supporting timber. The chimney will have lead flashing fitted to stop the leak. I was hoping to perhaps treat the rotted timbers and perhaps reinforce the rafter and support but advice is needed here what treatment is best and the best way to repair the damage.
Thank you

You may be able to sister the rafter with a proper cut and screw it to the existing rafter in order to save the support. The breast plate and some of the deck boards don't look too happy, either. Are there plans in the works to address them?

Thanks for getting back to me. By sister onto the rafter I presume this means glueing and screwing another piece or rafter of about say 3 feet to the existing rafter to repair the end. By the breast plate do you mean the piece of wood which is horizontal and fixed to the chimney breast to which the rafter is leaning against? If yes then I am not if sure this can be treated or will need to be replaced, what do you think? Are the deck boards the lattes which the tiles hang onto? The house is nearly 100 yrs old so they have become discoloured but they are sound to touch.
Sorry for not knowing all the proper terms for the roof parts

I was wondering if you had orange mold on the roof. I see it is lattice to hold the terra cotta tile. Cool. No leaks, then I presume. If you can't get to the board surrounding the chimney to which the rafter is attached, and if it is in sound shape, just attach the sistered rafter to it with screws. Sistering is what you said, glue and screw new piece cut at angle and as long as you can. 3' may be a little skimpy as you want to replicate the strength of the rafter for a distance due to the rotting on the end.
