We started building a carport two years ago, but never finished it. Now it has been standing half-finished for two winters without "protection." Winter is approaching again, and I'm wondering if I should protect the wood somehow or if it will survive another winter? What should one do in that case, oil it, paint it?
The posts have turned gray. The glulam beam shows some water impact and is full of spots (mold). The roof battens at the edge by the tar paper appear a bit water-damaged.
We plan to build the front this spring and reinforce the posts so they become a bit sturdier.
My carport that I built 10 years ago I didn't treat at all. Now more nicely grayed, and it shall remain so. No oil or paint will ever come on it. Grayed is the absolute best wood protection you can have. So let it gray.
A tip is to check if the roofing felt can withstand being exposed to UV for as long as 2 years. Most rolls of roofing felt last 3 months and some up to 1 year.

Thanks for the tip! There are concrete tiles on the roof. It's only the outermost row where the felt is exposed. We'll probably trim a small part there. But it might be worth adding an extra length of roofing felt where there haven't been any roof tiles.

Can you leave wood untreated and exposed to the elements (rain and snow)? Won't it get damaged then?

Eventually, after about 50 to 100 years, there may be some parts that need attention. Joking aside, paint is mostly about appearance as long as the construction is properly executed. Think of old barns. The wooden facade there may not have been repainted for many, many years, but as long as the roof is intact, they tend to last a long time.
Then there's a big difference between, for instance, a facade that dries between times and a "ground construction" of wood in contact with "wet" ground and thus constantly moist. The latter doesn't last nearly as long as the facade.

I might have oiled the end of the glulam beam.
