Hello,

We nailed the sill last weekend and the frame erection with rafters was completed during the week.

I covered everything in the garage with a tarp. And during the week, it rained a couple of times. Now when I uncovered it to start putting up the roof, I realized that a large puddle of water had formed in one place and another spot. So the sill has been standing in water (a few millimeters) for several days. Am I foolish if I put up the outer roof and hope that it can be dried out with a construction heater? Or does the sill need to be replaced?

I'm really worried if it needs to be replaced. Then it's just a matter of tearing everything down.

Yep.
It is completely normal for the timber to get wet. It dries when it is under a roof. If it is really soaked, you can use a dehumidifier when the building is enclosed.
 
Thanks for the quick responses. Now it feels calmer ☺
I'll continue building and throw in a building fan directed at the damp sill. And I'll set up a dehumidifier in the garage.

The risk is that the problem repeats when you park a wet and snowy car, as the drywall and wood behind it become damp if you don't have sloping towards the floor drain or door opening. A tip that is too late for the thread creator but which garage builders in the planning stage can adopt is to cast or build a 100mm plinth and place the walls on it. This also solves the issue of the outer panel being too close to the ground at the entrance.
 
I've realized it now. As I've said, having redone everything, I've realized that a raised base would have been a clear choice. I find the slab odd. It's a foundation company that poured the slab. I think the slope away from the wall should be better.

Is there any moisture-resistant baseboard that can be installed and then sealed with silicone along the floor to prevent future water problems?
 
What exposure class do you have for the concrete? A regular concrete floor poorly withstands saltwater from the car. It often requires some form of surface treatment, in conjunction with which you can level a slope from the wall. Even better, level a slope, lay tiles, and install a baseboard with tile slabs.

Do not know if you have plastered yet, otherwise the easiest is to replace the outermost plaster with Minerit and apply a sealant along the floor angle so you have a wall that can withstand a lot in terms of moisture.

Regarding concrete, one should have an XD concrete in a garage if driving a car in and out, especially during winter.
