Moreover they can cause major water damage inside the home. <\/span><\/p>\n<p><span style=\"font-size: 14pt;\">Fortunately roof ice dams can be prevented with proper attic insulation and roof ventilation.\u00a0<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\">So before the cold weather and snow hits this winter inspect your roof and attic this fall.<\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\">First take a look at your roof. When inspecting it, make sure there is a ridge vent and that it is by no means blocked up from venting attic air out through it.<\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\">The ridge vent should run nearly the entire length of the roof peak. Then take a look at the soffit vents. Make sure you have some, and that they too are not clogged up.<\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\">The soffit and ridge vents ensure cool outside air is drawn into the attic via the soffit vents and then vented out through the ridge vent. This flow of cold air pulls any small amount of warm moist air that may have worked its way up from the finished lower levels of the house and into the attic.<\/span><\/p>\n<table style=\"width: 100%;\">\n<tbody>\n<tr>\n<td style=\"text-align: left;\" width=\"50%\"><span style=\"font-size: 14pt;\">Next take a look in your attic. Make sure that your attic has the proper amount of insulation in it for your climate region. <\/span><\/p>\n<p><span style=\"font-size: 14pt;\">Pay particular attention to the attic floor. If there is inadequate insulation in it, warm moist air will work its way up into the attic during the cold winter months.\u00a0When it does, it will heat up the roof sheathing and cause the snow that is in contact with the shingled roof to melt.<\/span><\/td>\n<td style=\"text-align: center;\" width=\"47%\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-6652 \" src=\"http:\/\/homeadditionplus.com\/dev\/wp-content\/uploads\/2016\/12\/ice_dams.jpg\" alt=\"How to prevent ice dams this winter.\" width=\"275\" height=\"206\" \/><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\">When the snow begins to melt from its underside it drips down the roof shingles until it refreezes near the colder roof eaves. As the water refreezes the ice dams grow in size. Eventually enough melting snow water will work its way up behind the shingles, and when it does that\u2019s where the real disasters begin to happen.<\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\">The melted snow water drips into the attic, and then onto the drywall ceilings. If left unchecked, the water will continue to work its way downward through the house.<\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\">The main goal in preventing roof ice dams is to ensure that as little warm moist air as possible works its way up into the attic, and any that does gets quickly drawn out of the attic. Ultimately the main objective is to ensure the attic is close to the outside ambient air temperature as possible. Doing so will prevent the possibility of causing the roof snow from melting from its bottom side.<\/span><\/p>\n<table style=\"width: 100%;\">\n<tbody>\n<tr>\n<td style=\"text-align: left;\" width=\"50%\"><span style=\"font-size: 14pt;\">To know how much attic insulation your home requires visit the Department of Energy\u2019s website. <\/span><\/p>\n<p><span style=\"font-size: 14pt;\">It lists recommend insulation R-values for each area of a home for the various climate regions around the country. <\/span><\/p>\n<p><span style=\"font-size: 14pt;\">Also keep in mind that it is important that the requisite amount of attic insulation be installed properly. <\/span><\/p>\n<p><span style=\"font-size: 14pt;\">If installed improperly, such that there are open paths from the heated lower levels of the home to the attic, then significant attic heating will occur.<\/span><\/p>\n<p><span style=\"font-size: 14pt;\">Not only will this situation lead to ice dams, it will also cause you to have higher monthly heating bills. <\/span><\/td>\n<td style=\"text-align: center;\" width=\"49%\"><a href=\"http:\/\/homeadditionplus.com\/dev\/home_addition_bid_sheets\/asphalt-shingle-roofing-bid-sheet\/\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-6302\" src=\"http:\/\/homeadditionplus.com\/dev\/wp-content\/uploads\/2016\/12\/Asphalt_Shingle_Roofing_Bid_Sheet_CP-225x300.jpg\" alt=\"Asphalt Shingle Roofing Bid Sheet\" width=\"225\" height=\"300\" srcset=\"https:\/\/homeadditionplus.com\/dev\/wp-content\/uploads\/2016\/12\/Asphalt_Shingle_Roofing_Bid_Sheet_CP-225x300.jpg 225w, https:\/\/homeadditionplus.com\/dev\/wp-content\/uploads\/2016\/12\/Asphalt_Shingle_Roofing_Bid_Sheet_CP.jpg 384w\" sizes=\"auto, (max-width: 225px) 100vw, 225px\" \/><\/a><\/p>\n<p><span style=\"font-size: 14pt;\">Use this <span style=\"text-decoration: underline;\"><a href=\"http:\/\/homeadditionplus.com\/dev\/home_addition_bid_sheets\/asphalt-shingle-roofing-bid-sheet\/\"><strong><span style=\"color: #0000ff; text-decoration: underline;\">roofing installation checklist<\/span><\/strong><\/a><\/span> to save time and money on your roofing project.<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\">Consequently, when installing attic insulation, make sure there are no air gaps between ceiling joists bays. Moreover pay particular attention in preventing air gaps around chimneys and vent stacks.<\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\">Also check the attic insulation around the soffit vent areas. Make sure the attic insulation is in no way clogging them and preventing the flow of outside air into the attic.<\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\">Another important item to check in the attic is the bathroom exhaust vents. Make sure they are vented not just into the attic, but instead out of the home via ductwork. The last thing you want to do is blow warm moist air from the bathroom up into the attic. It\u2019s a killer for creating roof ice dams.<\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\">If you still have concerns after addressing the attic insulation and roof venting items, consider installing ice dam heating cables along your home\u2019s roof eaves. They are inexpensive and easy to install. Roof heat cables are much better for your asphalt roof shingles then raking snow off your roof after every snowstorm. Not only can snow roof rakes be tough on your asphalt shingles, it is a time consuming chore to have to do after every snowstorm.<\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\">After performing all of these tasks and making corrective actions where necessary you should find that your home is ice dam free this coming winter.<\/span><\/p>\n<\/div>\n<hr \/>\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\"><span style=\"color: #008000;\"><b>For more help on Shingling Your Home&#8217;s Roof<\/b><\/span><span style=\"color: #0b0000;\">, see HomeAdditionPlus.com\u2019s <\/span><strong><a href=\"http:\/\/homeadditionplus.com\/dev\/home_addition_bid_sheets\/asphalt-shingle-roofing-bid-sheet\/\"><span style=\"color: #0000ff;\">Asphalt Shingle Roofing Bid Sheet<\/span><\/a><\/strong>. <span style=\"color: #0b0000;\">The<\/span> <strong><a href=\"http:\/\/homeadditionplus.com\/dev\/home_addition_bid_sheets\/asphalt-shingle-roofing-bid-sheet\/\"><span style=\"color: #0000ff;\">Asphalt Shingle Roofing Bid Sheet<\/span><\/a><\/strong> <span style=\"color: #0b0000;\">will help to ensure<\/span> <span style=\"color: #0b0000;\">that your roof won&#8217;t end up with a blue tarp over it and a dumpster sitting in your yard for weeks as you wait for the roofing contractor to come back and finish roofing your home.<\/span><\/span><\/p>\n<p><a href=\"http:\/\/homeadditionplus.com\/dev\/home_addition_bid_sheets\/asphalt-shingle-roofing-bid-sheet\/\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-6302 aligncenter\" src=\"http:\/\/homeadditionplus.com\/dev\/wp-content\/uploads\/2016\/12\/Asphalt_Shingle_Roofing_Bid_Sheet_CP-225x300.jpg\" alt=\"Asphalt Shingle Roofing Bid Sheet\" width=\"225\" height=\"300\" srcset=\"https:\/\/homeadditionplus.com\/dev\/wp-content\/uploads\/2016\/12\/Asphalt_Shingle_Roofing_Bid_Sheet_CP-225x300.jpg 225w, https:\/\/homeadditionplus.com\/dev\/wp-content\/uploads\/2016\/12\/Asphalt_Shingle_Roofing_Bid_Sheet_CP.jpg 384w\" sizes=\"auto, (max-width: 225px) 100vw, 225px\" \/><\/a><\/p>\n<p style=\"text-align: left;\"><span style=\"color: #008000;
