Hello @Kevin Izquierdo, typically most exterior work needs to be finished up before the onset of cold weather. You may be able to sneak some work by but it's not ideal. Concrete needs time to cure, and can be weakened if it freezes before it cures. Roofing shingles shouldn't be put down in winter because they don't properly "bond" and the nail holes won't seal. Vinyl siding is actually designed to expand and contract with the weather changes. I've seen one job that was done in the winter where the contractor didn't leave a gap for expansion. As soon as the temperature went up the siding expanded but didn't have anywhere to go. It was like looking at the ocean.
If you have a large project you can always get the outside stuff done first and then work on the interior during the colder months. Hope this helps.
