I'm making plans to convert some of my parking to covered parking. I'm curious about what peoples' experience has been as far as what level of construction gives the best return. Sure, better is better, but how much better? I have a large fleet, so it's a matter of balancing quality with quantity. I'm asking here because in our rainy Western WA climate the answer will be different from Maine or Texas. I'm planning a shop building with inside parking space certainly, the more the better. What I'm wondering about is the value of also putting up carports for some of the others. This could vary from minimal to deluxe, I'm wondering what the sweet spots are in our climate I's like to hear from those who have upgraded from one level to another, how much difference in result they saw? Obviously more is better, but how much? Waterproof covers are a lot better than nothing. It seems like getting them out from under the rain under a dry carport is a considerable step up, even from keeping them under a waterproof tarp. The next stage would be a 'modified carport' in which some kinds of walls or fencing might be added, for security or visuals and as a windbreak, but not sealed. This seems to be good for a budget or for skating under permitting. Otherwise - how much improvement is this over sitting under a tarp outside? Because the next step is an enclosed garage. This would cost more, but guessing the jump up is considerable. Still, with venting and no insulation, I wonder how much improvement is this? Next up is adding insulation, and I hear many people who build garages advise installing insulation right away. I'm guessing this is a big jump in regulating temperature and therefore a corresponding improvement in preservation. Next beyond that is heated garage. That's gotta be better, how much better? Thanks in advance for your thoughts.
