Our slate roof (c. 1896) developed some leaks after a recent blizzard. The leaks appear to emanate from two "valleys" in the center of the house. Some repair work was done on these same areas last December. (Receipt said slates were replaced, fascia board was re-attached, flashings were resealed "as needed.") We are wondering what steps we need to take to prevent such leaks from happening in the future? Is this too much to expect? One roofer requested 500$ to come and do a repair - however, he didn't detail what exactly needed to be done. I haven't examined the slate up close, but my guess, after looking at the pics on your site, that it's gray/black, from VT or PA. There is a slate on the ground under the snow that I can dig up.

Sounds like you may have had some slates ripped out from snow slides after the heavy snow.
The leaks may be related to back up issues since you say the leaks started after a heavy snow,not a big rainstorm.There may also be problems related to insulation and ventilation that are contributing to the ice backup if that is whats causing your leaks.
First step might be to remove the snow accumulation so a skilled slater could observe the roof firsthand and determine if immediate repairs are required or if it can wait for warmer weather.Work can be performed now but it will cost more due to riskier nature of the roof.
You say on your other post that the slate looks "tired".It could be possible that it's useful life is nearing it's end,if for instance it is a soft slate.
There is a lot of good hard slate in that area of Mass. too so you really need an expert to guide you before you make any costly moves.
Dig out that slate and determine what it's origin is.
roofers warranties vary just like their prices.

Could be that your valleys just need replaced. If the slate is good, then it's a routine job for a house that old. If the slate is shot, it's not worth the money to replace the valleys.
