I'm a contractor in Maine and we certainly have a lot of experience with ice dams. An ice dam can be the quickest way to force water under the roof shingles even on a roof in good shape. I have had mixed results with heat tapes. When they are used properly, they can be somewhat effective. Most folks expect to see a nice bare zig zag pattern along the edge of ...

Ok gentilmen , lets talk ice dams. First and foremost, what causes an ice dam to form anyway. Heat trapped in an attic, either from heat loss from the house or sun beating on the roof, cannot escape quickly and melts snow on the roof. This water drains to the bottom of the roof where it runs across a cold edge and freezes. The overhang of your roof (soffit ...

I would suggest a roof rake - like this. You would start about 3-4 feet up, crack through ice and then rake down. If you have a tall roof this becomes a safety issue and might need two people - one to secure ladder. It isn't easy work. Also if you can safely get on top of the roof it is much easier to push the snow off.

The NYCOEM has no authority over NJ. I'm guessing you received the notice as part of an alert system you signed up form. Mailing list, twitter feed, etc. The reason it's important for people in NYC to clear their roofs is because roofs generally are right over the sidewalks. You don't want melting snow dripping on the walks and freezing or worse, having ...

You are right, Salt will eventually harm or "shell" concrete. I would suggest potassium chloride. This product will de-ice down to apx 15 F and will not harm the concrete or adjoining lawns or other plantings. Potassium chloride comes in a variety of brand names and can be found at most hardware stores. We use it all the time for roof de-icing because it ...

I had bad ice dams after last years blizzard in DC. My roofer told me to just break up the dams taking care not to damage the underlying asphalt shingles. I ended up using a large rubber mallet. It probably wasn't the best approach but I figured the cost of repairing some shingles would be better than repairing any water damage inside the ceiling/walls of ...

Attempt No.1 Acquire small plastic container. Drill small holes around base to allow water to flow out. Fill with salt. Place under exhaust vent. Wait and see what happens. I'm hoping the moisture in the exhaust will drip into the container of salt, and then run out carrying salt with it. This might have the added benefit of dispersing salt to the ...

Well, fixing the damage won't prevent it from happening again, so to fix this and prevent further damages from ice in the future, you will need to install some hardware. First, you are going to need to get out the ladder and , with some assistance, push the down spout back up and re-attach it to the elbow. I'd use extra fasteners, and possibly a short rubber ...

Electric cables can be fixed there very well. Let's say we use 2 mm thick cables with low wattage (10 W/m). Firstly you cut 2 mm wide and 3 mm deep cuts to the bottom side of your steps (using a hand circular saw). They should be parallel going from side to side. Put silicone and cables into the cut doing S bends, they should just fit in there. Cover the ...

You can pick up a cheap water pump that you can use to remove the water. If you have a Harbor Freight in your area, they have a good selection of cheap pumps. If your drain is metal, you can use a brush torch with a 15 pound propane tank to help remove the ice. Use it to help break up the ice. It will probably not be efficient to melt all of the ice. ...

99% of the time there is (or should be) no need to remove snow from a roof that is properly built for the area it is in. "Properly built for the area it is in" should include the ability to hold up the expected maximum snow load for that area until it melts. As a side note, in new construction, it is often VERY affordable to add 10-20 pounds per square foot ...

1It is very wrong. You CANNOT have a cord passing through siding, walls, or any other finished structure/surface. For both code and safety reasons. The receptacle MUST be outside. If it is close to the heat tape you'll just need to coil the cord up. National Electrical Code 2011 Chapter 4 Equipment for General Use Article 400 Flexible Cords ...

Provided the water is no higher than a few inches, you could go to Lowes and buy 10 or 15 bags of sand and dam up the garage entrance. After the ice in the drains melts, stack the bags near the garage for future use. Tip: Back the car right up to where you want the sand to make unloading easier.

I saw a roof rake on This Old House about a year ago that looked so simple, yet brilliant. Instead of having to scrape a little bit of snow at a time down to you or to push, this device slid a sheet of plastic between the roof and the snow so that one big column came down at one time. I don't have the need for one but it looked like a real time saver.

This part of the foundation is most likely spreading out a roof load from a sizable portion of the sunroom roof. If the soil supporting the foundation has eroded away, this will need to be rectified some time next year. For now, get a bag of ready mix mortar, the kind you just add water to, it has sand and cement already mixed in in the correct proportion. ...

I think shinning an infrared heater on the steps would be quite cost effective and very easy. I have this $60 one in my garage and am impressed with the bag for the buck. Maybe the mounting point would allow you to use it to make the porch more enjoyable in the late fall / early spring and you only shine it on the step during the winter? If you want to ...

Such a vent terminal can work, depending on your roof's micro climate. Depending on prevailing wind, solar orientation, drifting patterns, etc. there is often an area of the roof, usually near the ridge, which is relatively free of snow. If you must vent on the roof, this is where it should go, regardless of the type. As B. White indicated, a wall outlet is ...

If the cool down the exhaust gasses more you will reduce the level on condensation that is build up on the end of the exhaust pipe. The heat exchange in the furnace may not be working as very well as possible due to not having enough air being blown over it. (With water based systems it is often due to have the boiler set to high, so stopping the boiler ...

How many turns does your shutoff switch take to close? If it is more than half a turn, it's a gate valve and not a ball valve. Gate valves are inferior to ball valves and rarely do they fully close. If this is the case, you still have pressure in your sprinkler system (though the flow-rate will be vastly decreased.) Once a ball valve is in place, the ...

It looks to me like it's still the sprinkler pipe, they're attached at the top? So that line that's covered in ice is probably the supply that comes from inside your house, and the line going down goes out to the sprinkler system, and there is a backflow preventer at the very top where they connect. When you shut it off, there was still water in the line ...
