Well, buy one, and a pile of lumber, and get busy.
After the 15th, one, let us know if it was worth it. BTW, pay attention to the triangles and make the copies exactly like the original, or you lose some stiffness. |

Think about the Pound psi of your roofing material. If the professionals don't build their own, then there must be a reason.

For that money I'd build my own. I would absolutely use joist hanger nails over those spike plates--I could not trust those things alone.

I gotta say, I build things for a living and I cannot make a truss for less than I can buy one premade.

most likely delivery and storage costs. Actual material and labor wouldn't be much, but transporting those things and having a place to store them until sold is probably a huge part of the cost. |

I built my own trusses. 24' span (plus 2' overhang each end). Materials were $55 per truss. Plans built, mostly 2X6 with 2X4 bracing. Plywood gussets nailed and glued on both sides of each joint.
The plans I had gave instructions on building the jig. And exact dimensions on each component part. My wife built half the trusses herself. |

Buy some 2x10s and go cut some rafters! I am sure you can find a website that will explain to you the rpocess of cutting a rafter. Then you will have a nice attic for storage.

only if you screw it up.  Pre-built have the benefit of convenience and time savings. If you have the time, can make a jig if you have a bunch to build, and triple check your work, you should be good to go. People built stick frame houses on site for a long time before parts came pre-fabbed from the factory. |

I often find that when I try to build something that is easy to buy ready made, I often wish I had just shelled out the cash because the work turns out to be a PITA. I have never built roof trusses, but I notice that it seems everyone buys them, not builds them. I built a tank-like picnic table from scratch several years ago, very sturdy, but at the end I wish I had bought and assembled a kit and spent the balance of the weekend at the range. But, people vary in cash on hand, mechanical ability, and free time availability. If you enjoy the work, then there is no reason in the world to buy them. Except, as others note, finding good lumber at the home supply store.... |

If you want any sort of grade 1 lumber you aint gonna find it at Home Depot or Lowes that is for sure. All the big stores have is grade 2 stuff. Thats why finding enough straight boards is hard as hell.

The size truss you are looking at should be under a hundred dollars. If I build it, the material will run around fifty bucks per truss.Then I haul enough material for twenty of them to the shop. Cull out the bad boards and return half of them, eat the rest, and get enough material to make the last ten trusses. Build a half assed jig to speed things up, which takes almost as much time as I save. I have an easy hour plus into each truss. At my labor rate, I am right there five dollars over what I could buy pre-built trusses for. I forget to charge for the fastners and I lose out on the ten percent kickback I get from the lumber yard every month. That's why I don't build my own. You, you have other reasons. Unless you have some carpentry skills and a big shop, you are sort of like that home-taught gunsmith with his first new dremel tool.

Also they store indoors, coming from a period of outdoor storage. When the lumber comes in, it dries out too fast and warps from the sudden change. |

Keep in mind your trusses still need to get on the roof. IMO, you'd have the roof stick framed by the time you got the trusses built. And rafters are much easier to drag up than 26' trusses. 2x8 SPF will span your runs just fine.

If they are around $75 I would definatly buy them, but over $100 I think is pretty sad. On a side note I don't understand comments like the second one. I can't think of one single thing in the history of this world that was thought out and worked right the first time. |

First of you wont get a 30 ft piece of wood in the ones you buy. They will be gusseted together. About 60 bucks apiece would be right. Buy from a lumber yard who builds them. You cannot hardly build one for that unless you like working for 2.00 an hour.

Shop around, you should be able to buy them cheaper. If not, just use rafters - You don't HAVE to use trusses. Rafters are lighter, easier to handle, infinitely more simple to cut, and easier to build with.
I do not recommend trying to make your own trusses. Would you go to the hardware store, buy a piece of plumbing pipe and make your own gun barrel? |

The use of Machine Stress Rated (MSR) lumber in manufactured trusses means that the component members are individually tested for stiffness which correlates to the breaking strength. They know how stiff the final product will be and what it will support for snow load. Each truss will behave just like its neighbor and the roof will remain flat and true. The trusses can be lighter weight than what you would have to build using lumber that is only visually graded. You don't find this lumber at your lumber yard, unless they order it in for you. It brings a premium price for a good reason, and that is part of what you pay for in a manufactured truss. |

The same reason that smokers don't roll their own cigarretts. Conveinence. If you have the time, by all means "roll your own', trusses. Add some plywood gussetts while your at it. Yours will probably have a better quality and dimensional consistancey than some illiterate border crosser anyway.
Use hurricane clips to tie them to the top plate. |

You just proved my point. Proper equipment is only part of the equation. Using pipe to make a gun barrel is analogous to using home center 2x4s to fab your own trusses. Incorrect material for the application in both cases. Re-read red-don's post regarding MSR lumber. The CORRECT lumber is not cheap, especially in the small quantity you are going to need. I doubt that you will be able to save enough to justify the time/effort invested. Why are you so hung up on using trusses in the first place? If you are doing the work yourself, the cheapest way is to just cut some rafters and collar ties. Trusses are popular with builders because they save time/labor. From what you've posted, you seem more worried about saving money than time. Another thing to consider - Do you have a local building code? An inspector might not be impressed (favorably) by home-brew trusses. |

Roof trusses should be the cheapest alternative and I would buy them only from the manufacturer. Find out who actually makes them in your area, not who sells them. Tell them you are a builder and if they are really up to speed they will want at least a drawing to engineer them for your proposed use, size, roofing material, loading, etc.
Most roof trusses are not made with specially graded lumber around here and most of the cheap homes are built with trusses. Believe me, if those guys could shave a dollar off of the entire house they would do it in a heartbeat. Trusses around here are built with mostly 2x4's and gang nails in some plant staffed by $6 an hour workers, delivered (meaning dumped in the yard) and hand set up to the roof one at a time. If you go with rafters and a ridge beam, the lumber will cost a lot more as you won't be able to use 2x4's for your rafters and ceiling joists and you may be using 2x10's and 2x8's. You will get an attic though and that may be worth more than saving money on the roof structure. If you do go with trusses be sure to tell them that you want to store stuff in the attic, or they will be designed to only carry the load of the ceiling for your building and they will make no allowance for storing ammo in your attic. There are also engineered lumber systems that are made with compressed wood and glue that are becoming more popular. Wooden "I" joists, or Trus joists have also become popular because they are made from smaller trees that are chipped up and glued into the desired shape. Some of these are much stronger than natural wood. Here is Weyerhaeuser's product site for engineered lumber: www.trusjoist.com/ |

Until the glue fails. Have you ever seen wood glue that worked worth a damn? I know I haven't. I've seen those crap products used in four houses including my great-niece's. Huber made the ones used above her garage. She's saving money now to replace them after two of them fell on her car and put huge dents in the hood and busted the windshield. A coworker has those type of joists under the floor of his new house. I don't know who makes them, but they have the name "Silent Floor" on them. He's selling the house because the cost of repair is going to be more than he can borrow against the house with the equity he has so he can't afford to salvage the house. Imagine how expensive it would be to replace the floor joists in an entire house.z |

Ok, talk to me about rafters. Do I save a buncch of money there? Are they strong in tornado country? I am willing to do either, but I don't want to worry about strength.
ETA: the thing with rafters is that the roof line is not parallel to the door. How do I support a beam over a door? |

Trusses will generally be more expensive on the material end and less expensive on the install labor.
Stick framing = more expensive labor and less expensive material. There are times and places for trusses IMO but not as widely as people use them. I wouldn't try to make your own as they are engineered for specific laods and bearing points. If you're talking about just a plain gable roof for your garage just cut a patteren to use for the rest of the joists. Pretty easy actually. |

Trusses should be cheaper than a cut roof, but if you are dead set on doing it yourself, definitely cut the ridge rafters and joists instead for making trusses.
Also remember if you use trusses, you will not be able have any attic storage, as most trusses are not rated for the load. |
