Splicing Roof Rafters To Floors

Measure rafter spacings of 24 inches with a tape measure and plan the splice to fall between rafters.

Splicing roof rafters to floors. This floating beam is so wrong. This is called prescriptive solutions. A 30 foot roof for instance will need at least two boards. Sometime we just need a longer piece of wood like a hip king rafter.

Calculate where a ridge beam splice will be needed. If you are building trusses it is easy to make part of the roof into a cantilevered extension. Structures such as sheds or barns can be frames with rafters every 24 again make sure to consult local codes. This makes splicing roof rafter plates accurate and stable.

It is always better to have a large rafter rather than be concerned with a sagging roof. Whatever the reason the secret to a good splice is the connection method and good workmanship. If your roof is strong enough it can extend beyond the support walls without external bracing. You can splice rafter plates by hand with nails or use a framing gun.

Just make one of the rafter members extend beyond the cross tie. If your project had a rafter length of 8 or less a safe and strong method is to use 2x8 framed 16 on center. The roof is 4 12 pitch with 3x8 timber rafters 4 on center a 3x10 timber ridge beam and 2x8 tongue and groove boards above. There s no sense installing a beam that s not supported by a post.

But that s what this deck builder did. Cut each board to 15 feet with a circular saw so the splice will fall. Maybe the builder assumed that attaching the beam to the end of another beam would do the trick. A cantilever is any structure such as a roof or floor overhang that is braced internally.

How not to splice beams. A 16 foot board will end at a rafter with 24 inch spacing.
