This method was also pretty ineffective - it created a bunch of holes in the ice dam, but so what? Most of the ice dam was still there in the end. Take off your pantyhose, fill 'em up with calcium chloride or something similar, and toss 'em on your roof perpendicular to the ice dams.
The idea is that the salt will leak through the pantyhose and create channels for the water to drain through, preventing water from leaking in to your house. I filled one pantyhose leg with "Ice Melt", which contained a blend of calcium chloride and rock salt. I filled another with an ice melting salt that didn't have the contents labeled - I suspect it was just rock salt.
I also poured the Ice Melt in a perpendicular line along the ice dam, using far less salt than I used in either of the pantyhose. I did this just to compare the results. The pantyhose were a bit of a bust for me. With salt alone being so effective, why bother with the pantyhose?
I've heard several opinions on this:. After a week of near-zero temps, the pantyhose looked just the same. They hadn't even made a dent. I don't think I would have the patience to do this if I had water leaking in to my house. Also, this could lead to damaged gutters. My friend did this at a house he owned in Saint Louis Park These photos all show the heat cables after about one day.
Stringing up the cable was also very unsafe. I received a request to use a blowtorch on an ice dam, so I tried it. This video was taken about four years ago. Sorry for the poor audio. A pressure washer will certainly remove ice dams, but it will create a ridiculous ice mess below, and will surely damage the shingles.

This was one method that I didn't even test. The photo below shows what can happen to a roof after a pressure washer or high-temp pressure washer is used on a roof. There is a big difference between a steamer and high-temperature pressure washer. In the video below, Steve Kuhl discusses the difference with me. Ice dams are no fun.
As I mentioned at the beginning of this blog, hiring a pro to steam the ice dams off is the only thing I recommend. Oh, and one more piece of advice: if you know someone who has water leaking in to their house from ice dams, don't tell them to "stop focusing on how to get rid of the ice dam, and spend your time fixing what caused it.

Blog By Reuben Saltzman. Axe The most obvious way to get rid of ice dams is to take a blunt instrument and hack away at the ice dams. Ice Pick This sounds like a natural choice, doesn't it? Roof Tablets Yes, this is a product designed specifically for preventing damage from ice dams. I've heard several opinions on this: The pantyhose will contain the salt and prevent runoff. The idea is apparently to leave the pantyhose there all winter.
The pantyhose can be 'flung' on to the roof with a rope - no need for a ladder. After the work is done, you pull the pantyhose back down. The pantyhose will gradually release the salt. The pantyhose method works much faster if you start by pouring water on the pantyhose. I didn't try this myself.
When salt alone is used, it will wash out within a week and the ice channel will freeze over again. This deterioration appears to have been caused by water penetrating the roof. Photo 6 and Photo 7. Photo 6 left and Photo 7 right show the deteriorated ceiling conditions inside the front part of the structure. Photos courtesy of fire department. Whenever the fire department identifies a structure that is unsafe and represents a hazard, such as following a structure fire, the Fire Commissioner will send a written report to the Commissioner of the Department of Buildings requesting that the identified structure be demolished.
Any fire department member can report a hazardous building. Currently, there is no process for the Department of Buildings to notify the fire department whenever a hazardous structure is identified during normal building inspections or has been identified for demolition.
Simpson is tweeting about the debates again tonight. I next built the North wall in order to get the window opening out of the way. Those animate tools are you, your friends, and family that have agreed to help, so a fine line must be maintained in order to avoid a workers strike. It is also a good idea to add a few extra pieces of lumber such as 2x4's and 2x6's in case you measure once and need to cut twice. How big do you want the garage to be?
In this incident, the building owners had been unresponsive to court citations. The Department of Buildings had not taken possession of the structure and the structure was not marked as being hazardous. The structure had never been pre-planned by the fire department. When viewed from the street, the structure appeared to be a vacant structure awaiting a new tenant.
Homeless persons frequently entered the structure through the rear. Just a few weeks prior to the fire, a person was arrested at the structure for burning wiring that had been removed from the buildings. A large vacant commercial structure, located just north of the public alley, was formerly used as a manufacturing facility and the fire department had been dispatched to the manufacturing site several times for small structure fires.
This contributed to the confusion concerning the correct address during the initial dispatch. The fire department estimated that there are more than 20, structures with bowstring truss roofs within the city. Prior to , the bowstring truss roof design was one of the most common design types for large commercial and industrial structures. The bowstring truss roof was commonly used in facilities such as automobile dealerships and repair facilities, bowling alleys, grocery stores, and industrial complexes wherever large open floor spaces with limited interior supports were needed.
The curved top chord members were made either by sawing straight lumber into curved shapes or laminating multiple smaller pieces bent over a jig to the desired shape. Bottom chord members were typically constructed with large, straight lumber members joined with either wood or metal bolted splice plates, located near mid-span, to achieve the required length. The top and bottom chord members were fastened together at the truss ends with U-shaped steel heels, or end shoes, bolted to both chord members. The principles of bowstring truss construction are similar to other types of truss construction in that web members are used to form multiple series of triangles that transfer tension from the bottom chord and compression from the top chord of the truss onto the load bearing walls.
One big difference with the bowstring truss is that the compressional forces within the top chord act to force the load bearing walls outward as well as downward. Bowstring truss roof systems may suffer from a little-known phenomenon related to inaccuracies in early industry-accepted truss design assumptions. One significant design deficiency involves the tensile strength of the bottom chord.
