Roof Collapsings: Did You Know? And Fun Snow Comics.

February 2, 2011

On Channel 7, I just saw about 5 stories on roof collapsings all having occurred around Boston and up through the North Shore and New Hampshire. Jeremy Reiner shared a map indicating that depending on the region of MA you live in, roofs have to be able to sustain a specific amount of weight per square foot– specifically because of all the snow we get.

Boston, North Shore and South Shore roofs must sustain weight between 30 and 40 pounds per square foot. As you goto the Cape, the numbers decrease to about 20-25 pounds. Central MA was around 25-30 and Western MA requires roofs to sustain 40 lbs or more.

Many of the roofs that collapsed were those of commercial buildings because of the flat top. This reminded me, of course, of the ice dam madness that occurs most frequently (and more likely) on low pitch roofs. Click here to see that post.

As far as I could tell, no one is reported injured, but in most instances, there were people inside. How totally freaky that must have been.

This also means that there has got to be at least 30-40 pounds of snow per square foot on our roofs! And this is not coming to an end just yet– apparently, there’s another snownnoyance* on Saturday.

Snowmageddon’s Over… Or Is It? Ice Dam Danger Prevails! And Why This Involves Old Pantyhose.

January 14, 2011

Those pesky ice dams.

What is an Ice Dam, you ask?

An ice dam is a block of ice that forms at the edge of the roof (you can usually tell it’s there if you have a lot of icicles!). The dam effect is that the excess water from the snow pools behind it. Further, this great amount of water can leak into your house and damage walls, ceilings and/or other areas. (Major problems!)

It gets worse when you don’t realize you have an ice dam- the water can refreeze, creating additional dams– many times, it drifts into the gutters–freezing your gutters as well!

Ice dams are prevented by improving the ventilation of your home and the insulation in your attic.

There are some quicker solutions, but I want to emphasize the following before I tell you what they are:

WARNING!

Performing ice dam removal is risking severe personal injury and damage to the roof if not done properly. Never walk on a snow covered roof and make sure if your using a ladder you follow the proper safety procedures. I highly suggest contacting professionals with the proper equipment and roofing experience to carry out this job.

I stole that disclaimer from another site. But, don’t say I didn’t warn you about the dangers of fixing an ice dam.

Now.

I found this one online — not sure if it works, but it was charming and quirky enough that I figured I could share it:

Fill a leg of a discarded pair of panty hose with a calcium chloride ice melter. Lay the hose onto the roof so it crosses the ice dam and overhangs the gutter. If necessary, use a long-handled garden rake or hoe to push it into position.

The calcium chloride will eventually melt through the snow and ice and create a channel for water to flow down into the gutters or off the roof.

Weird, but hey- if it works, it works. Again, I do not recommend everyone jump on their roof with pantyhose. I’m just sharing the Internet’s advice with you. 🙂 And I want you to be conscious of what may be happening on your roof.

There is also a product called RoofMelt– AsSeenonTV! Though, I know little to nothing about it.
