Niskayuna, NY. Client called to have roof inspected because last winter they had the snow removed from the roof and the contractor said the roof was bouncy during the the snow removal. Today I went up on the roof and it was bouncy. Went up in the attic space and the rafters were 2x6 @ 16" with a 2x8 ridge board. No hangers or collar ties were on this roof causing the roof to be bouncy.
