I have a two-story home with a metal roof. I bought the home three
years ago. Every year ice builds up on the roof ans slowly slides
off. Last year it became 6 inches thick and when it finally let go it
destroyed my metal bulkhead and damaged my chimney. I'd like to
remove the snow before it turns to ice. Is there a roof rake that
will reach the top of my house (the peak is almost 50 feet from the
ground)? Any other alternatives?
I doubt it, and even if they did it would be unmanageable. I have one
with 3 extensions totaling 20 feet, and it's a real workout to use,
especially if there's any wind at all.
If you're not having trouble with ice dams, just worried about snow
sliding off, have a roofer install the little brackets designed to
prevent the snow from sliding. I don't know what they are called, but
they are common around here on older houses with steep slate roofs
that are very prone to snow slides. It's common to see one or two
rows of the little brackets installed 2-3 feet from the roof's edge.
Don't know if they can be used on metal roofs, but worth asking.
Damaged your chimney? How so? You need a stronger bulkhead and perhaps a
little building over it. You need to get the snow to start sliding off
the roof sooner while it's still soft. Why doesn't it? Maybe you need to
coat the metal roof with something slick. I assume it's not a modern
metal roof, those let the snow slide easily. The old galvanized/painted
ones can be too ruff and rusted. Or is it a slope problem, not enough
Can't see your house from here. What do you mean by bulkhead? A picture
with a link would help. A flat porch roof, maybe?
As to the chimney- if it isn't at the peak of the roof, it should have a
cricket uphill from it to divert snow and rain around it.
Best course of action may be a site survey by 2 or 3 professional
roofers in your area, that have metal roof experience. (Many do not.)
They know the local climate and codes, and hopefully know what works.
No, it won't be cheap, but steep roof work 50 feet off the ground is
generally not a good idea for DIY anyway. Stuff that can kill you is no
place to cut corners.
And insulate the sun? ;)
The roof brackets another poster mentioned are called snowbirds or
snow guards. Here's one manufacturer's web site that has a nifty
little installation video. I've never used adhesive for attaching
them to a metal roof, but they have some pretty amazing adhesives out
there so I don't see why it wouldn't work.
Thanks fo rthe relpies, let me try to clarify. I want the snow to
slide off the roof before it turns to ice. We have cathedral ceilings
with no chimney. I suspect heat is the culprit. The roof is only 5
years old, pretty steep, and and pretty smooth. I just need a way to
get the snow off after each storm.
