Flooring guy here. We use some pretty nasty industrial stuff sometimes. Everything from TSP (which isn't made any more I don't think) to muratic acid. The average homeowner does not want to mess with those as they can easily damage stuff when used improperly. We use them for time constraints (people who hire us tend to not want to pay for us to wait around on things, time is money).
Far better is to use stuff made for homeowners. It is slower and less powerful, but it still gets the job done. Something like this:
https://www.amazon.com/30-SECONDS-Outdoor-Cleaner-Gallon/dp/B072F4CSC3/
Bleach will also work but hydrogen peroxide (milder type of bleach) should be used first before going full on with regular chlorine bleach. And everything should be used with windows open and ventilation going on. Even stuff that doesn't seem that bad, can cause headaches or stuff like that.
And the area needs cleared before cleaning. No wood anywere near where water or cleaner can be splashed on. If it is something like wall studs, covering them with visqueen and stapling it on will suffice for keeping splashes off them.
Maybe Wet and Forget I’ve used it on the side of the house and other places but not the roof. It takes a while but really works.
It looks like powdery mildew, I've had good results using Daconil your local Ace hardware should carry it. I also recommend using a biological fungicide as a soil drench and spray.

You might see about having whoever does the roof work add a zinc strip along the top of your roof line. When the rainwater runs down it, it carries just enough of the zinc along with it to prevent moss growing back for years.
It's rather popular here in the Seattle area at least, and I'm pretty sure we share a similar climate.
i use this brand

Hardware stores usually wont have the stuff you'll want to use, places like Lowes and Home Depot only carry Mosser Lee brand sphagnum which is basically 50% sticks and twigs, not very good stuff. Lowes and Home depot will also never carry unfertilized perlite in my experience. If you have any smaller, specifically plant shops in your town thats where you would want to look, otherwise, it is easy to find on amazon. Here is links to the stuff youll want:
If you cant find anything locally and have to wait on shipping, id reccomend flushing your pot with distilled water after removing all of the fertilizer pellets. When I say flush I mean really flush. Pour a lot of water in and let it run out the bottom, youre trying to rinse out all the possible mineral build up to help your plant live longer until your new soil arrives. Another user also mentioned more sunlight which is also a good idea, they like filtered sun all day if possible, southern facing windows are ideal but western facing windows will do as well.
It appears to be bacterial wilt, there aren't any good treatments for it. Some people have reported success using a biological control, I have had real good success using it for fungal diseases. it colonizes the plant ahead on the pathogen preventing the infection. The organism's is in the soil so use it both as a spray and a soil drench, and use it prophylactically on any future plantings Biological fungicide: https://www.amazon.com/Southern-Ag-Garden-Friendly-Fungicide/dp/B014174BZM/ref=sr_1_6?crid=TGIPX1L8IP82&dchild=1&keywords=biological+fungicide&qid=1627595152&sprefix=biological+fung%2Caps%2C191&sr=8-6

Hydroguard is a great product, but we can get the same bacteria strain Bacillus amyloliquefaciens. In Garden Friendly Fungicide it's the same product only highly concentrated and at a fraction of the price. https://www.amazon.com/dp/B014174BZM/ref=cm_sw_r_cp_apa_glt_fabc_TCAQRBCYS95575PRYRGY?_encoding=UTF8&psc=1
1 ml to 5 gallons is more than enough
It is this brand, and not as wet as you describe. I can start more and put it near a window.
It does look like it, I've had good results in the past with a biological control used as both a spray and as a soil drench.

You shouldn't be able to find the seed potatoes at harvest, they should have sprouted stems and leaves above ground and tubers below.
