Hello folks,
Amateur question, hope you don’t mind.
Recently moved into new house. Have spent many hours just wandering around looking at different aspects to make sure they are in good shape for the long term. (My wife just thinks I’m lost)
My porch ceiling is still open. I was checking out the rafters, connectors and such and noticed the nails attaching the rafters to the house and the ceiling joist to the house are discolored with rust.
I assume they got wet before the porch roof was completed and started to rust. Maybe just humidity caused it?
I also assume my framers should have used galvanized or SS nails for that application. Is that correct?
My questions are – Will they continue to rust even though they are not exposed to the rain anymore?
Should I go back and use some galvanized nails to reinforce what is already there?
Thank you
By the way, the wood is not PT

My house is from 1886, has no galv nails. As long as they don't stay wet (embedded in wet wood), you'll only get surface rust. And if they're embedded in constantly wet wood, there's another problem!

Thanks McDesign, I get a little paranoid sometimes. I'm getting ready to put my porch ceiling up this summer and figured that its easier to address it now if it needed it. I've never learned much while I was talking
As far as I know surface rust is normal, if just from humidity. If area is dry normally (undercover, inside, above grade, etc.) no galv nails necessary. Keep wandering around and asking questions, most home owners wait til the "floor seems squishy".
Thanks for the reassurance, I'll keep wandering and posting questions I'm sure.
By the way, my wife really thinks I'm crazy when I'm wander in the rain. I like to see where all the water goes.
Its amazing how much water comes off of a roof. I put a 50 gallon barrel under a downspout with the idea that I could use the water to help me with my ongoing battle to establish some sort of lawn. Filled and overflowed in no time at all during a rain storm the other day. I can see how water causes so much damage if it is not drained properly...
Thanks again

Hereabouts they used to install cisterns for that purpose. Route all the downspouts through a filter box (to keep dirt/leaves out) and then on to the cistern. You could fill a 10' deep cistern with just rainwater off the roof. Cistern is underground, so you don't have to worry about it freezing in the winter. You then just have it rigged to a pump and VIOLA! Water for your lawn/garden/house. For some of the rural folks, you would top off your cistern via your well and then run all the house off the cistern. If you ran out of water, just have some hauled in and dumped in the cistern.
I know there is a formula for calculating how much water you can get off a roof based on its size and pitch per inch of rain...but I don't remember the calculation off the top of my head.
good luck with your projects.

Thanks JohnT8
One day, I would love to work something like that out. We went 625' on our well and got 2 gallons/minute. We were blessed to get that much but with such a slow recovery I hate to run the sprinkler for extended amounts of time.
I see all of that water running off during the rain storms and I want to utilize it somehow.
Good luck to you alsoI've never learned much while I was talking
Sounds like you're in a similar situation to those rural setups. If the budget ever materialized, you could do the same thing: Put in a good-sized cistern. route your gutters to the filter box and then on to the cistern... and then utilize the well to keep the cistern at a certain level and just run the house off the cistern.
So instead of being restricted to 2gal/min off the well, the well just keeps the cistern 1/2 full (or whatever). At which point your pressure tank running off the cistern determines your house's water pressure and you're good to go as long as there is water in the cistern. The pump from well to cistern can take the rest of the day to fill it back up to the 1/2 mark. And if it rains enough, you're not drawing off the well.
It gets more complex if you're wanting to drink the water. More filters and water treatment involved.
I've also seen the rare setup where someone with city water has routed some separate plumbing for the cistern/well. So they end up running toilets, hoses, clothes washer, etc off the cistern water and run 'city' water to any location where you'd be drinking the water.jt8

I appreciate you taking the time to explain that. I would love to implement one day....

I live on the beach and only use 316 grade stainless steel. The original homebuilder used galvanized which is rusting out and failing. I have to special-order them from Simpson-Strongtie through my lumberyard but using stainless allows me to sleep soundly at night.
