Cracked plaster from new roof. How long do I wait to repair?
 
Not sure if this belongs in this forum or under painting, but I thought that I'd try here first.

Anyway, we just had a tile roof installed last month. House is 60 years old stucco over block and the previous roof was shingles. We hired an engineer and added support well beyond his recommendations.

He did state, however, that due to the original builders placing struts midway across the living room ceiling (not above a load bearing wall), we could expect cracking to reoccur there. Sure enough, a visibly patched old hairline crack has reopened.

The surprise, though, is a thin, horizontal crack midway up the wall of non-bearing wall running parallel to the rafters, and perpendicular to the ceiling crack. I wasn't aware of there being any load placed on that particular wall.

I'm not concerned about it as it's probably just settlement.

However, I'm curious about how long to wait before I patch the cracks? I'm inclined to wait until this spring when a snow load should cause additional deformation and more cracking.

Since plaster has almost not give, is there an approach that I should take when patching? Say...cut a 6" wide gap and replace with drywall maybe? Or, is there any elastomeric patch compound that will flex and be more forgiving?

Thanks.

Very logical thinking. I, too, will be interested in hearing some informed opinions on this one.

We find that the cracking and bowing of non load bearing upper floor partition walls is common on new build houses when the partitions are built before the roof is tiled. If the crack is hairline normal filling by the decorators should be OK. Plasterers use scrim when covering larger cracks.

Thanks for the reassurance.
