The short answer
Choose For Exposure Maintenance And Door Use
Burnaby’s wet months make finish durability, corrosion protection, drainage and perimeter sealing important. The best material also depends on whether the garage is attached, heated, used as a workspace or exposed to direct rain and wind.
Material is only one part of performance. Door construction, insulation, hardware, finish, installation and weather seals can matter as much as whether the exterior is steel, composite, aluminum or wood.
