Is there any use for scrap treated wood?

Agree with this comment and fully support his do not burn treated wood. The chemicals used to treat it when burned give off smoke that is not good for you. Preposterous. Poisonous smoke is very good to blow directly towards Canadian small boys abusers and stupid people like Stan Brown and intransigent neighbours. |

Many times when the snow on a roof melts, the temp is well below freezing and it melts due to the sun, and or heat leakage through the roof. So, when that water drips down onto the AC, it would probably freeze pretty quickly and cause a large ice buildup on the fan and screen above it. Besides, it keeps out other stuff, esp in the late Fall. It worked well for you for 41 yrs. -- Buffalo |

It worked well for you for 41 yrs. It's always a good idea to make a quick visual inspection in the Spring, before using the A/C for the summer season. -- Char Jackson |

If significant ice falls from the roof, I'm guessing a tarp isn't going to do much to help, but the bigger question might be, why is there significant ice on the roof? That should be a rare event, and if it's not, it probably indicates heat leaking through the roof. Fix that and you won't have to worry about the condenser, plus you can enjoy lower heating bills. When I lived in the northern states, my brother and I used to drive around and 'look at things' as an excuse to take a car out when the streets were snow covered and slippery enough to have fun. One of the things we'd notice and comment on was when every house on a street had a snow-covered roof except one. That was the one that had an improperly insulated attic, allowing heat to leak through the roof. Day-time thaws followed by night-time freezes may build up ice on a roof around dusk as the temp drops. Why? Because even with a well-insulated and ventilated attic the eaves will usually be colder than the roof. In fact, there is a real danger of an ice-dam forming and mel****er invading the attic. You can minimise the risks, but you can't eliminate them. Ice dams aren't caused by poor insulation, exactly, but proper insulation plays a role. Instead, the primary cause is poor ventilation. A properly ventilated roof will ensure that the roof stays at ambient temperature throughout the roof's surface. If you can achieve that, which is quite possible, then you will have eliminated the possibility of ice dams. Bottom line, if snow is melting from the roof of one house while the neighboring houses of similar design and construction aren't exhibiting the same thing, you can be sure there's improper insulation and/or ventilation. That house almost certainly has heating and cooling bills that are higher than they need to be, as well as the possibility of water damage that can become quite serious, not to mention an increased likelihood of mold and mildew. -- Char Jackson |
