I run a marina in southeast Missouri. One of the biggest things that can hurt our marina is snow/ice build-up on our roofs. When the snow starts piling up we have to get on the roof and shovel the snow off before it sinks the docks. Last year I borrowed a small Toro gas snowblower and it cruised through the snow with ease, however, it only threw the snow about 6', which meant I spent a lot of time blowing snow that I had already blown (if that makes sense). The other drawback is that the roof is your typical corrugated barn tin, with ridges and sheet metal screws sticking up - the snow blower kept getting snagged on the screws. I would like to find a lightweight (have to haul it up on a ladder to the roof) snowblower that can deal with uneven surfaces. I'm no he-man so am hoping for something that weighs around 30-50 lb. I've been looking at the battery/cordless options and think that's going to be my best bet (unless I can find a gas snowblower that weighs around 30-40 lb). It would have to be able to throw snow at least 20' to get the snow off the roof. The uneven surface issue leads me to think I will need a rubber scraper/blade solution. We have to get the snow off the roof before it gets greater than 3", otherwise our docks start to sink. This means I don't need a very powerful snow blower. I welcome any constructive input/suggestions/thoughts/ideas/etc that you would share.
