Hi Lou,

Saw this post early in the morning but didn't have time to respond. I wonder if this is what you need:

R802.3 Framing details. Rafters shall be framed to ridge board or to each other with a gusset plate as a tie. Ridge board shall be at least 1-inch nominal thickness and not less in depth than the cut end of the rafter. All all valleys and hips there shall be a valley or hip rafter not less than 2-inch nominal thickness and not less in depth than the cut end of the rafter. Hip valley rafters shall be supported at the ridge by a brace to a bearing partition or be designed to carry and distribute the specified load at that pint. Where the roof pitch is less than three units vertical in 12 units horizontal , structural members that support rafters and ceiling joists, such as ridge beams, hips and valleys, shall be designed as beams.

OT - OF!!!

What kind of separation? What could be the cause, possible lateral movement? This might help:

R802.8 Lateral support. Rafters and ceiling joists having a depth-to-thickness ratio exceeding 5 to 1 based on nominal dimensions shall be provided with lateral support at points of bearing to prevent rotation.

R802.8.1 Bridging. Rafters and ceiling joists having a depth-to-thickness ratio exceeding 6 to 1 based on nominal dimensions shall be supported laterally by solid blocking, diagonal bridging (wood or metal) or continuous 1-inch by 3-inch wood strip nailed across the rafters or ceiling joists at intervals not exceeding 8 feet.

Lou,

I do believe you posted at IN as well on this item.

Make sure you are watching the various code requirements at the municipality you are inspecting. The "wind rating" levels dictact what works and what doesn't the closer you get to the Gulf of Mexico.

For example ... roll-up garage doors that can be installed in Spring, TX (Northwest of Houston) will not be accepted on the Southeast side of Houston due to inland wind level ratings due to hurricanes, etc., etc.
