Our old house in New England has a steep pitched metal roof and no gutters. Our front door is right under a roof valley, so it is unusable on rainy days and all of winter. The water running down the valley has rotted out our building sill, and we have to get it replaced. I don’t want the same thing to happen to the new sill! Installing gutters is not currently an option because the winter snow avalanches would just rip them away. I have read about snow guards, but have never seen any in real life. How well do they work, are they hard to install, will they work when 18” of snow falls on the roof? Will the snow guards slow down the avalanches enough to keep gutters in place? Alternatively, should we just build a porch to divert precipitation further from the foundation? Any advice is welcome!
You might also be able to install a rain diverter to send some or all of that water somewhere more convenient. Depends on the actual layout of the roof.
You’re right, but I’d like to resolve the snow issue as well.
I have snow guards on my metal roof in Wisconsin. They work pretty well. Light snow slips under them but they're good at holding the heavy snow that would take your gutters off.
I have the ones that look like horizontal bars.
