Concerns About Truss Sizes and Overhangs When Designing a Floor Plan

Concerns About Truss Sizes and Overhangs When Designing a Floor Plan

Reader ART in EADS writes:

Hello Mike, my wife and I are making floor plans for a future pole barn house. We see that numerous companies offer buildings in common L x W x H dimensions as well as some customized sizes. We want to utilize all space without any overbuilding so we are looking at required interior spaces to accept how we intend to furnish and used the house. So we are drawing out floor plans and taking in to account wall thicknesses both interior and exterior. Questions have come up concerning truss sizes with and without overhangs. 1. Are there usually standard truss sizes for clear spans vs customized? i.e. 30′, 40′, 50′ etc. 2. Is there a difference in clear spans with a 40′ with and 40′ without overhangs? 2.a. What about pricing differences? i.e. #% additional for n” in overhang?”

I am going to open a bag and let a cat out here – Hansen Pole Buildings will be building metal connector plated wood trusses, for our clients, in just a few short months.

nailing trussesI spent two decades (in what I call a ‘past life’) in management and/or ownership of truss manufacturing facilities. For 22 years, we have outsourced our truss needs and it all worked well until Covid – where lead times for even obtaining preliminary truss designs stretched from days to weeks (and weeks), designs were not necessarily very efficient (due to out sourcing to people in third world countries who have never seen a 2×4), and lead times for production extended out sometimes as long as six months.

We provide buildings to clients in all 50 states, so we deal with snow loads ranging from none to over 400 psf (pounds per square foot) and design wind speeds from mild to in excess of 200 miles per hour. Along with this, clients who are blowing in attic insulation, need different heel heights depending upon thickness of insulation. In summary – there is no ‘standard’ truss when it comes to us.

I did learn a few things in architecture school. Work from inside out – do not try to fit your wants and needs within a pre-ordained box just because someone said using a “standard” size might be cheaper. Differences in dimensions from “standard” are pennies per square foot, not dollars.

Popular home spaces and sizes need to be determined: https://www.hansenpolebuildings.com/2019/09/room-in-a-barndominium/ and https://www.hansenpolebuildings.com/2019/09/the-first-tool-to-construct-your-own-barndominium/.

As far as overhangs are concerned, personally I would go without doors before I would go without overhangs. Doors can be added later, overhangs cannot. Without overhangs, buildings tend to look industrial. Overhangs afford weather protection for door openings, shade south facing windows from brutal sun, move ‘weather’ away from walls (helping to keep moisture out from under building and keeping walls cleaner), plus they afford a valuable air intake for vented attic spaces.

From a truss cost standpoint, those overhangs add very little to one’s investment.

Roof Leaks, DIY or Hire Builder, and Building Width

This week the Pole Barn Guru answers reader questions about on old roof that leaks due to nails used in attaching steel, a request for builder referrals, and if a Hansen Building is available in a 48′ width– yes, they are.

DEAR POLE BARN GURU: My older metal barn complete with roofing nails, not screws, leaks badly. If I install eve trim would I use gutters also? Now, the building, 96×40 has neither. It leaks under the eves. Replacing the nails has worked some. KAREN in ELMA

DEAR KAREN: Hansen Pole Buildings’ warehouse is a roughly 50 year old post frame building with roof steel attached with nails and it leaked like a sieve. We used two cases of “super whammy” caulking to try to seal around nails, it helped some, but ultimately our only solution was new roof steel. Although it sounds painfully expensive, it really is going to be your only true solution. When you order new steel, make sure it comes with a factory applied integral condensation control and use 1-1/2″ diaphragm screws to attach (they are larger diameter, powder coated and have EPDM washers).

Continuous seamless gutters are always a good investment, provided you add snow breaks on your roof, if you are in snow country.

DEAR POLE BARN GURU: We are looking for a builder to put up a 70’x40′ pole structure for us — do you have any names of contractors/individuals who have put a Hansen building in the area? ESMEE in WENATCHEE

DEAR ESMEE: Your new building kit is designed for the average physically capable person, who can and will read and follow instructions, to successfully construct your own beautiful building shell (and most of our clients do DIY – saving tens of thousands of dollars). We’ve had clients ranging from septuagenarians to fathers bonding with their teenage daughters erect their own buildings, so chances are – you can as well!

Hansen Buildings Construction ManualYour new building investment includes full multi-page 24” x 36” structural blueprints detailing the location and attachment of every piece (as well as suitable for obtaining Building Permits), the industry’s best, fully illustrated, step-by-step installation manual, and unlimited technical support from people who have actually built post frame buildings. Even better – it includes our industry leading Limited Lifetime Structural warranty!

Currently (and for the foreseeable future) there is a nationwide shortage of building erectors. Many high quality erectors are booked out into 2023. We would strongly encourage you to consider erecting your own building shell.

For those without the time or inclination, we have an extensive independent Builder Network covering the contiguous 48 states (https://www.hansenpolebuildings.com/find-a-builder/). We can assist you in getting erection labor pricing as well as introducing you to potential builders.

A CAUTION in regards to ANY erector: If an erector tells you they can begin quickly it is generally either a big red flag, or you are being price gouged. ALWAYS THOROUGHLY VET ANY CONTRACTOR https://www.hansenpolebuildings.com/2018/04/vetting-building-contractor/


DEAR POLE BARN GURU: Do your pole barns come in 48’ width?
