Beginning here with our index to building framing, this article series describes methods of building framing and describes common framing defects and how they can be avoided or repaired. We include building framing materials, connectors, fasteners, tools, and related topics.
Page top photo: this antique barn in upstate New York illustrates how remarkably plastic a wood-framed or timber-framed structure can be if it moves slowly over an extended period. Sadly this barn was later dis-assembled and its timbers sold.

Straw bale houses are easy to build, affordable, super energy efficient, environmentally friendly, attractive, and can be designed to match the builder’s personal space needs, esthetics and budget. Despite mushrooming interest in the technique, however, most straw bale books focus on “selling” the dream of straw bale building, but don’t adequately address the most critical issues faced by bale house builders.
Moreover, since many developments in this field are recent, few books are completely up to date with the latest techniques. More Straw Bale Building is designed to fill this gap.
A completely rewritten edition of the 20,000-copy best--selling original, it leads the potential builder through the entire process of building a bale structure, tackling all the practical issues: finding and choosing bales; developing sound building plans; roofing; electrical, plumbing, and heating systems; building code compliance; and special concerns for builders in northern climates.

But none of these includes a corrugated wood roof deck.
I looked at your photo but could not see any corrugated wood roof deck .
Please, if you can, try posting another photo that shows, more-clearly, the decking about which you're asking.
Is it possible that you're referring to a fiberboard (wood or plant fiber based) insulating sheathing that may have been used as roof decking, and like that described at
and below we include photo of conventional corrugated paper such as is sold on Amazon

Does anyone know what this corrugated wood roof deck is called or have any info on a brand name? This building is a school built around 1958 in Hamilton, ON, Canada.

by inspectapedia.com.moderator - old broke back mare roof rebuild ideas.
@Harry james,
Thanks, those suggestions will help other readers;
Indeed as a carpenter myself, we often found it was cheaper to simply way over build than to hire a structural engineer or civil engineer simply to size up the minimum adequate beam, post, or gusset, and furthermore, the engineering was pretty murky anyhow if we're talking about an old building not framed to modern standards, and perhaps with some damage from insects, rot or whatever.
Where you do want a design professional is for bigger jobs and/or where there are life safety worries at stake.

Thank you for the informative approaches to the old broke back mare roof rebuild ideas. The shredded was a good highlight.
Just wanted to share that I have seen these roofs alot and unfortunately they all seem to have they're own set of problem. recently I've learned to be as thrifty as can be in my approaches and have found that plywood scraps that often are thrown in the dumpster are handy for gusset repairs, broken or slit cord mends.
I always oversize the gusset well beyond the damage as to insure it can handle the tension and the memory wood can have once it has settled in.
It can also be an economical fix to marry along each side of sagging rafters, again larger than existing Carter.
Oh ...and fastener size, type, quantity and placement do matter. Could do more damage than good.
On 2021-06-28 by danjoefriedman (mod) - Modular home renovation considerations
@Dave,
It is certainly possible to construct a raised beam into whose sides ceiling joists are abutted using proper structural connections.
Depending on the loads involved and the beam length, you might prefer engineered products such as a glulam beam. Clearly you don't want to remove any supporting walls before a thorough inspection of the framing scheme of the home.
You are correct that many modulars are set in two sections per floor level, and there will be a center or party wall that is in essence doubled. Your wood beams would need therefore to support the floors above both of those.

I am considering buying a 2 story Cape Cod home that is modular. I believe the wall in the center of the house is actual 2 walls side by side running gable end to gable end.
Is it possible to remove a portion of these walls by inserting a structural beam either under or beside the structural members that support the second floor bedroom? My concern is the ceiling heights are 7'-6" on the first floor and I do not want the beam to be below that height.
I am completely unfamiliar with modular home framing, I do understand residential framing. Thanks!

- leaks at roof and wall lead to extensive building damage - missed by home inspector?
Ryan
Thank you for the leak damage report and photos - this will help other readers, and perhaps some home inspectors who may be more careful to either inspect more-thoroughly or at the very least, to warn their clients of the limits of their inspection.
In my OPINION (and I can only guess), that roof damage may have been hard to spot from the ground and easy to spot from an on-roof inspection.
A topic of considerable argument among inspectors is the question of making an on-roof inspection. My own view is that if you can safely get onto the roof and safely walk on it, then you should do so; if you can't, you need to explain what could be wrong that you couldn't see. (And in the case of leaks, you ought to look inside for corroborating clues).
A subset of inspectors - I don't say this was yours because again, I don't know - are those who are more focused on speed and making a buck than on thoroughness and responsibility.
Years ago, a Canadian inspector fell to his death while trying to access a roof. He knew the access was dangerous (a poorly secured access ladder on a building) and had mentioned his worry to his wife the morning before the inspection.
After that tragic death, those of us on the ASHI Standards Committee led a move to clarify that no home inspector can be required to do anything nor go anywhere that she or he felt was unsafe or that could not be safely accessed; the decision of what's unsafe (like entering some crawl spaces or going on some roofs) must be left in the hands of the inspector.
But some of the quick and fa$st crowd I cited above leapt on that rule to simplify the scope of their inspection: "We do not go on the roof" for example, stated in a home inspection disclaimer document, falls short, in my opinion, when it is not accompanied by some warnings about the costs and risks of undiscovered leaks or damage.
Now turning to that window leak, that damage is so extreme that I am amazed that there were no visible clues before the demolition in your photo.
If you have photos of the interior, exterior, window sill, and floor in that area, and of the ceiling or crawl area below that damage, and that were taken before you opened the wall, it would be instructive to view them.

Hi there. We just purchased a house in Pennsylvania that had been vacant for about 10 years.
I joke around and tell people the previous owner had a bit of money and used the house as a large storage unit, because he lived in a condo for the last 10 years and "never got around to selling the house".
Two days after moving in, we discovered two baseball sized holes in the roof. Somehow the inspector missed it, but during the inspection, they noted light moisture behind a window wall directly below the holes. Admitting negligence, the inspection company paid for the roof to be repaired.
We finally pulled back the sheetrock in early December and discovered the holes in the roof did way more damage than we realized.
The wood framing, insulation and subfloor were soaked. We sealed everything off, and now that it's dry, things are starting to crumble a bit.
So, we need to hire a contractor to come out and (we think) rebuild that front wall... at least in that particular section.
The ironic thing is, we finally met our neighbors a week or so back.
They told us, "Yeah, our son tried buying that house a few years ago but they couldn't come to a deal because there was damage from a tree coming down on the roof, it wasn't repaired properly, and there was a ton of moisture behind a wall that they didn't want to deal with."
Another potential buyer had the house inspected and backed out for some unknown reason.
We asked to see that inspection report and the owner declined. So, we have reason to believe the previous owner was aware of the damage.
