Roof Trusses

[lemonreid]

I have a ranch house with 'W' roof trusses which were cut away by a previous owner. The middle two members that meet with the roof rafters at the peak of the roof were cut off and in some cases "replaced" with verticle members from the bottom two joints of the W up to the roof rafters. I am looking for the proper way to repair this modification. The roof is light weight assfalt shingles, it has a slightly higher pitch than 4/12 (30%), and 12 of the 20 or so trusses were compromised.

Woww, sounds like a real butcher job. The new vertical webs, probably are not caring much load. If you can locate the original truss shop, then they can guide you with a repair plan. Any thing else is just a wild ... guess.

Are there any interior bearing walls? Are the trusses typical 2"x4" pine? Are you in a high wind or earthquare zone?

I have used 2"x6" syp #2 with steel mending plates to repair single broken webs.

There is no stamp on the trusses indicating the truss manufacturer. The house was built in the 60s. Earthquakes are an issue but are not common in this area, and there are no consistent high winds. This is probably why the roof looks as good as it does.

I'd venture to guess there are interior bearing walls now! There is a hallway flanked with walls running almost the length of the house. The trusses are made of 2X4 douglas fir.

Running new webs just outside of the peak of the truss with a horizontal bolt plate accross the two at the top, has been one thought by a solicited PE.

Any ideas on repair price for this type of contract work? I understand the PE fees can run up to $1000 for plans.

I would suggest local truss design engineer that has the software to design repairs.
Typical fee might be up to $600
