Snow covered decks are beautiful to look at. If you don’t use your deck, it would represent way more work if you had to clean it off, but there are reasons why you should.
Removing snow and ice from your deck reduces trip and fall hazards, and more so if you have stairs connected to the deck. Getting rid of the snow on decks around the house and foundation can also reduces the chance of water penetration into your home as well. This can occur either when the snow / ice naturally melts or does so as a result of heat loss from the home. In any event, it’s best to keep water away from your home ensuring there are proper drainage slopes.
When removing the snow from your deck, use a plastic snow shovel and shovel lengthwise along the boards (with the grain) to minimize surface damage. Avoid using salt / ice melters on your deck which may discolour / damage some surfaces. Try sand for traction, mindful that it can damage surfaces too.
While less of a concern with pressure treated wood, snow removal is more important with cedar. If you have vinyl or composite deck material, check with the manufacturer being mindful that these surfaces can be very slippery when snow / ice / dampness is present.
