My house was built for 40psf and my rafters started pulling away last week from the ridgeboard

Had over 30" of WET snow; the weight worked out to about 60psf BEFORE the rains that dumped over an inch last week. Needless to say once I heard the noises I took off work last friday and spent the day clearing off my roof. I think the total was over 130 structure failures in the last two week. Yesterday an old church pancaked and only left the front standing like in a western movie.
We are used to snow but it usually melts and doesn't hang around; even where I live in north east Connecticut I have over 30" on the ground. I have snow piles blocking my living room windows from the snow I threw off my roof. What made this snow odd was even on the front of my house it is a 11/12 pitch and I measured over 20". The back full dormer is 4/11 pitch and had the 30" still on it and was starting to give.
