Whether you need a permit depends on the deck design and local regulations. Most areas mandate a building permit if the deck is over a specific height or if it's attached to a pre-existing structure. Shorter, freestanding decks may not require a permit, but you should check with local zoning ordinances and your homeowners association for specifics.

No. In most cases, it’s not colder or freezing temperatures that affect decking materials but the amount of moisture that seeps into the materials as a result. For example, wood decking material is more likely to suffer from rot or decay when exposed to excess moisture from snow or ice. An extreme change in temperature can cause wood to expand or contract, but only if it’s not properly treated beforehand.

Rot loves moisture, so deck rot typically impacts the parts of a board that stay wet. This includes the underside of boards, in addition to support posts and joists. However, any part of a board can rot, given the right conditions. 

Many composite decking manufacturers, including the popular Trex brand, offer warranties that protect against warping under specific conditions. These warranties typically last between 20 and 50 years, but they usually exclude claims related to improper installation of the product. Some manufacturer warranties only cover decks built by certified professionals.
