comment How do I reattach a small roof over our back door, that has pulled away from the house?
We're a visual sort here, we're going to need to see some photos of this.

comment Wood slats for sound insulation
Anything is usually better than nothing, but in some cases, certain constructions can make things worse, it's not always intuitive. If you have exposed studs, you'll be far better off with real sound insulation, then placing the finish on resilient channels.

In what plumbing code is self venting and running traps allowed?

comment Rebar cattle guard
IMO the painted stripes are more like a deterrent than an actual barrier. It's probably more effective on busier roads where cattle are less likely to hang out on the roadway. I've seen cattle stumble across a real cattle guard when standing next to the guard, then getting spooked by an oncoming vehicle. If it were just paint, the whole group would be across instead of a couple individuals. Then the gig would be up. They may be fairly stupid, but they do learn.

comment L14-30 Plug & Generator
The bare copper and ground wire must be bonded to the grounding system, which in this case are metal boxes and conduit. A NEMA6-30 has no neutral, but a L14-30 does. How are you achieving a neutral conductor? The generator frame must be bonded to the trailer frame.

comment Is my Heat pump and gas furnace installation incorrect?
There's no real danger in heating mode, the risk is only in cooling mode. So take your time and do thorough research before bringing anyone in. I've no idea what "red tag" might be or if it's really a thing, I've no experience in Canada. I suspect if it's anything, it would come from either a building or utility inspector, not independent contractors. When the time comes for quotes, I doubt it will be an issue, but what do I know?

comment Add floor framing using joist hangers?
For 16"oc joist spacing, the hangers must be rated a minimum 400# total load. 11.75/2*1.33*(40LL+10DL)psf=391#

comment Is my Heat pump and gas furnace installation incorrect?
Off the top of my head I should think 500 would cover it, but I'm not current with HVAC labor costs. The time it takes also varies widely depending on existing conditions. The only way to find out is get some quotes from local outfits.

comment Accidentally Touching One Lead Of A Multimeter While Other Is In Electrical Outlet
How much of a shock would depend on what mode the meter is in. If it has a high current ammeter mode, it's going to to hurt... or worse. In AC voltage mode I believe the internal resistance is quite high and there may not be much of a shock. I'm pleased to say I never tested this theory, neither should anyone else unless they really know what they are doing. Just sayin' for the sake of discussion.

comment Help translate terminology relating to flat roof construction
70mm insulation board alone is a little scarce for roof insulation, but might there be more insulation in the roof structure? There's no way to know if this is a hot or cold roof from the description, it's what's below and how it's vented that would determine that. Any added insulation that's not waterproof needs a vapour barrier to prevent condensation from forming in the insulation.

comment Can 2 - 6“ flex ducts be combined into a single 8” rigid duct
You're probably OK with reduced area because of less friction, especially if the sharp bends are eliminated. I'd still rather be safe and go bigger. If 10" round doesn't fit you could always go with rectangular ducts.

comment What are my vapor-barrier options under Hardie siding?
FYI, house wrap is not a true vapor barrier, it's a weather barrier that is slightly permeable. True vapor barriers are installed on the warm side of insulation, the interior side in temperate climates.

comment Repairing area in exterior siding
Sorry, I'm not up to date with lumber costs. you're certainly not going to get any quantity discounts :) I haven't paid much attention to what Home Depot will do beyond cutting to length, I expect ripping a rabbet is beyond what they do, doesn't hurt to ask though! For the lengths involved, this could be done with a circular saw and a straight edge. For a small area, it wouldn't be the end of the world to forgo the shiplap and just rip to width, assuming a weather barrier is going on before the siding.

comment Noise reduction for roof air condensers
A thin membrane will offer very little noise reduction. Some units have optional isolation mounts specifically to reduce noise and vibration transmission. If not available, it's possible to fabricate something similar, but must be carefully detailed to facilitate sound mechanical attachment without transmitting vibrations.

comment Do TRIAC dimmers “wear out”?
I'm assuming we are talking about conventional dimmers and incandescent bulbs here. Have you tried changing bulbs? Heavy duty or "long life" bulbs have slightly heavier filaments and supports, they tend to make less noise. I'd believe filaments get louder before I'd believe the dimmer is causing the bulbs to be louder, though I'm not totally discounting the latter. But I'd expect the dimmer cause to take much longer than 3 years.
