I know roof trusses in our area are designed to take a load of snow, but how much is too much and you need to shovel it off?
I have got an ice dam from hell this year. I know the insulation and ventilation needs to be addressed. Any ideas on how to remove hundreds of lbs of ice from the gutter?
My my house is protected from the main wind which means it swirls and creates 4 to 5 ft drifts. Problems arise from that much heavy packed snow, usually creeping up under the shingles and causing leaks. Between my son and l we're semi-pro at keeping the snow at bay
on the straight angle parts of the roof we use a roof rake with a plastic slide attached and shovel the rest.
slide rakes are the bomb
The one I have :
Potassium chloride in panty hose is safe for shingles and plants, so they say compared to run of the mill ice melt for ice dams
Does this work well on hard packed snow or do you have to get it right away while it is still soft?
For ice dams, buy that heating cable for roofs. Run it the length of your gutter and down the gutter. Might have to wait till next year to install. Worked good for my old house.
If the ice dam is close to a hot water spigot, wait for a day above freezing and take the hose to it. The will break from from the gutters and you can throw the chucks out by hand. This is what I do. I also put the heat tape in.
