I am helping a friend build a duplex this summer (we are both novices) and need sone advice. The duplex has 2 single car garages in its middle. My question is this: The garage’s trusses will be perpendicular to the house’s trusses. Since the garage extends into the duplex’s roofline, we are at a loss on how to tie the 2 rooflines together. Any help would be appreciated.
Thanks, Rich

The truss manufacturer should be able to draw this up for you or maybe one of the boys will be able to help you here...I just can't see it with so little info.
Good luck,

*Post a sketch on here for us long distance, visually impaired folks. Do you have plans with elevation drawings? The truss company should be making up all the trusses from your plans and they just drop them off. You assemble them and see what ya get. You could also hire a carpenter for this portion of the project.Pete Draganic,In Cleve., Ohio call 216-271-6458
*If I understand you correctly, you will have a reverse gable roof on the garage tying into the roof of the main structure. This will form what are known as valleys. With trusses you should be able to set the trusses on the main roof then sheath it in. You may want to leave out a sheet or so in the middle of the intersection of the 2 structures,( bottom course ) for ventilation and access. Check your local code on this point.After sheathing the main roof, set the main trusses on the garage. If you don't have "valley sets" with your truss package, you will need to stick build the overframed valleys.After setting the trusses, establish a straight, level ridge line from the trusses to a point on the main roof. Now establish a point on the main roof near the wall plate that is in the same plain as the garage roof. These steps can be accomplished with a string line, level, and a straight edge. Repeat the second step on the opposite side. Now chalk a line between the points on both sides. This line will represent the intersection of the two roofs. If you have valley sets, the bottom chord will be beveled and you just continue setting them up the roof starting with the longest truss. Place them so the end of the vally sets dont't cross your chalk line. If you dont have valley sets, you will need to cut and install a ridge and jack rafters. Then sheath the garage roof and valleys and felt them in.This is a quick overview of the process and you can find more information and pictures in a good carpentry book. Good Luck kcoyner
*Just a quick note to Kcoyer - You said "If you have valley sets, the bottom chord will be beveled". This isn't necessarily true. Some truss companies bevel them, and some don't. It depends on the market they're in. A lot of things vary from market to market. In the Chicago area, truss manufacturers virtually always send valley sets. (AND bevel them) But move farther south in Illinois, and they almost never provide them at all. If they do, they're not beveled.Remember - "Blanket statements are never right"....(-:
*Ron, Your point is well taken, but the blanket statement is true, at least for me. I have never seen valley sets where the bottom chord is not beveled and wouldn't install them if they weren't. Maybe I should have said, "The easiest way to find the valley sets is consulting the engineered drawings which come with the trusses." OOPSThere goes another blanket statement.Sorrykcoyner
*kcoyner -Actually, not every truss company sends out engineered drawings with the trusses. Most areas I've worked in had no zoning, so there was no reason to. Any paperwork we sent out on jobs was always thrown away by the framers. Dang........Gotta watch those blanket statements..............(-:

Here is a blanket statement I don't mind making-- Thanks for the input. It was most helpful.
