Is my house support beam strong enough for the load?
Conflicting builder opinions and hidden framing details make it impossible to tell if a beam can safely handle a second story and roof.

Unedited, grouped by where they were said, most upvoted first within each place, each linked to the thread it came from.
“Was attempting some high arches. But if this is a structural beam, I'll change my plans. It's a truss roof, this is a 12' span going straight down the middle. Thoughts?”source ↗
“I noticed as they were demoing the existing siding the OSB around the bottom of the house on two sides of the house was bowed.”source ↗
“I can’t tell if this is a relic of the 90s and no house wrap or what, but I’m a little concerned and I don’t want my new siding to have a muffin top.”source ↗
“Naturally, this gap along the bottom of the wall looks concerning to me, it goes a good 12-18” back in places and I can’t actually figure out what is supporting it.”source ↗
“Just bought a house and noticed these gaps in the roof joists in the garage, is this normal, or does it need hangers and pulled back together?”source ↗
“Will that beam hold my weight? (~180lbs, plus the forces associated with using the rings)”source ↗
“Do I need to do anything to protect the beam, or reinforce it in any way?”source ↗
“most garage footings arent designed for that kind of live load”source ↗
“getting plumbing up there is the real headache, not just the load.”source ↗
“Unless whoever put the garage there in the first place had plans for a second story they wouldn't have paid the extra to provision for it.”source ↗
“A wedge of wood holding up the house in between the beam and the block”source ↗
“A metal jack sitting on a concrete pier with a 18-24” 2x4 holding the house up”source ↗
“What do you think? Is this a deal breaker, or is this something I could live with?”source ↗
“I was curious as to how possible this was or if it ends up being way more expensive than I am thinking.”source ↗
“The last thing I want is to not put in enough support and have the ceiling collapse.”source ↗
“One wall has about a 3-5 degree pitch from top to bottom. It’s not bowed out into the center. It’s top to bottom. The basement is finished. So I can’t see the state of the foundation from the interior.”source ↗
“Has anyone experienced this? Is there an issue. What are some recommendations?”source ↗
“I was worried about getting a structural engineer in for the pandora effect.”source ↗
“Does this look like a reasonable beam for an 18’ span supporting the second story and roof, or does anything stand out as concerning?”source ↗
“An Amish carpenter installed it, but my dad, who is a contractor, looked at it and doesn’t believe it’s adequate for the load.”source ↗
“Well because it’s a pole that im putting my weight on, im just worried the weight will harm the ceiling if it’s stuck to something electrical rather than a joist”source ↗
“I’m just concerned with it being so close to the light that it actually stuck to something electrical rather than a joist?”source ↗
