Thank you for any advice you can give me on this subject. BI<\/span><\/p>\n<p><span style=\"font-size: 14pt;\"><strong>Answer:<\/strong> BI, you raise some valid concerns. When building an addition there are two key areas you need to concern yourself with as it relates to home addition roofs, design and construction.<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\">First, it is important when <span style=\"text-decoration: underline;\"><a href=\"http:\/\/homeadditionplus.com\/dev\/home_articles\/home-addition-designs\/\"><strong><span style=\"color: #0000ff; text-decoration: underline;\">designing the home addition<\/span><\/strong><\/a><\/span> to make sure the new roof ties in properly to the new home.<\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\">In some cases the home addition roof may simply butt up against one of the side walls of the existing home and not come in any contact with the main roof. In this particular case it is important to consider, however, if the home addition roof will impact any existing doors or windows. In some situations you may be able to adjust the roof pitch or position of the room addition to not impede upon an exterior door or window, but in other situations you may have no choice but to eliminate the door or window altogether.<\/span><\/p>\n<table style=\"width: 100%;\">\n<tbody>\n<tr>\n<td style=\"text-align: left;\" width=\"50%\"><span style=\"font-size: 14pt;\">If your home addition roof is designed to intersect or tie into the existing roof, then you need to consider structural aspects of how the home addition roof ties into the main roof. <\/span><\/p>\n<p><span style=\"font-size: 14pt;\">I have seen cases where poor room addition roof designs result in the room addition roof peak perpendicularly intersecting the main roof line such that the room addition peak is higher than the main roof peak.\u00a0<\/span><\/td>\n<td style=\"text-align: center;\" width=\"47%\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-6315\" src=\"http:\/\/homeadditionplus.com\/dev\/wp-content\/uploads\/2016\/12\/Shingle_1-300x225.jpg\" alt=\"How to shingle roofs and roof valleys.\" width=\"271\" height=\"203\" srcset=\"https:\/\/homeadditionplus.com\/dev\/wp-content\/uploads\/2016\/12\/Shingle_1-300x225.jpg 300w, https:\/\/homeadditionplus.com\/dev\/wp-content\/uploads\/2016\/12\/Shingle_1.jpg 640w\" sizes=\"auto, (max-width: 271px) 100vw, 271px\" \/><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\">Imagine looking at a colonial style home from the road, where the front of the home runs parallel to the road, and seeing a triangular point sticking up dead center above the main home roof line.<\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\">This triangular point represents where the home addition roof peak ties into the main home. Unsightly to say the least!<\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: 14pt;\">The second major concern when it comes to home addition roofs is during the construction phase, particularly if the home addition roof ties into the existing roof. When tying a home addition roof into an existing home&#8217;s roof, shingles need to be removed from the main roof for proper roof construction. During this phase of the home addition project the main part of the home is at risk of water damage.<\/span><\/p>\n<table style=\"width: 100%;\">\n<tbody>\n<tr>\n<td style=\"text-align: left;\" width=\"50%\"><span style=\"font-size: 14pt;\">Consequently it is important that the main roof and home addition roof are shingled promptly after the construction of the home addition roof. During construction of the roof, vinyl tarps should always be placed on and fastened down over the exposed roof, while the roof remains un-shingled.<\/span><\/p>\n<p><span style=\"font-size: 14pt;\">Finally, when tying in a home addition roof perpendicular to a main roof line, roof valleys are formed. Make sure that the roofing contractor installs Ice and Water Shield in the valleys. Also, you may want to consider how the valleys are shingled. You can consider weaving shingles between the roof valleys or using flashing in the valleys where the shingles from adjoining roof lines tie into the flashed valleys.\u00a0<\/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;\">Get 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;
