http://www.homebuildingandrepairs.com/repairs/roofing/index.html Click on this link if you're looking for a little more information about home repairs, roofing and construction. Here's a common mistake do-it-yourselfers run into and I even had problems with it myself before gathering this information. Composition roof shingles can be repaired in a variety of different ways and if you're planning on using some type of sealant or tar compound to make the repair, then you should understand that water can get trapped under the roof shingles if certain breaks or joints between the shingles aren't filled properly. Hopefully I explained myself in the video, but if I didn't feel free to leave any questions in the comment area I will get to them as soon as possible.
