If it's the middle of the winter and you have ice dams or through past experience, you think they'll be forming soon there are some steps you can take. To start with, should don't have experience climbing on roofers New York in summer time months, especially with snow on it, then don't do it! Call a pro. What you can do is visit the local hardware store and purchase a snow rake that has an extendable handle made to pull snow off of the first few feet of the New York roofer and attempt to pull a number of that snow off, from the floor, until it has a chance to melt and refreeze along the New York roofing edges. You can also do this when the ice dam has formed and kept it from getting any bigger and give it an opportunity to melt, ideally.
Also, many roofing contractor NYC, us included, perform through the winter and frequently provide roofing company NYC snow removal services in addition to their typical commercial roofing NYC services. This is a service we're delighted to provide for our clients here in Massachusetts, for example. Again, please do not attempt to do this yourself. Between Arctic ladders and slippery roofing contractors NYC surfaces, it is a recipe for disaster for the inexperienced.
Additionally, there are some products on the marketplace which could assist in preventing ice dams before they shape and melting them if they've already formed. You should be able to find a house improvement store in the area that sells a product that is basically a coated, heated wire that you fasten along the borders of the NYC roofing contractors and then plugs in when the conditions are appropriate for your ice dams to form (see picture on right). These actually work fairly good, however, they are not solving the real issue which, clearly, is insulation and ventilation issues. They may be right for some houses in some circumstances though.
