Be very careful about modifying the truss in any way. Truss designs are sealed, legal documents and altering them would probably void any insurance claim for damage that might not even be directly related to the change. Many moons ago I ran a small truss plant for about 1-1/2 years and am very familiar with the legalities involved. Building inspectors are all over ANY alterations made during construction and would shoot down any permit application that involved a truss change, no matter how minor, without a sealed engineering drawing to back it up. Trusses with “tails” for eaves are designed at the beginning stage of their construction in the truss plant. One suggestion is to install secondary rafter extensions with tapered ends to match the roof slope between the trusses, fastening them at the exterior and center bearing wall top plates. A simple 2X4 is enough – there’s negligible load. Then run another of appropriate length under the roof deck attached to the extension. A return to a ledger on the side of the house sturdies up the unit and provides a soffet. Fastening to the underside of the roof deck shouldn’t be a big deal since, I presume, there’ll be a new roof installed to cover the eave. -- RonKl - New Jersey |
