Vinyl Vinyl siding is among the most common siding materials used in construction of residential dwellings. It allows a great deal of air to circulate behind the vinyl siding which, at least theoretically, helps moisture evaporate before it can penetrate through building wrap and cause damage to sheathing, framing and other building components. Unfortunately, if the building paper is not installed correctly such as when it is lapped starting at the top of the wall rather than at the bottom of the wall or installed vertically instead of horizontally, water can get behind the vinyl and cause severe damage. In addition, just like with other claddings, flashings must be installed correctly at interfaces between the vinyl and roofs, between the vinyl and decks and between the vinyl and various other building components such as windows, doors etc. failure to install these flashings or to do so correctly will often cause mold or other significant damage to building components. A careful evaluation of the building by a qualified expert is necessary in order for you to understand the condition of the building, the causes of any deficiencies in design, materials or construction methods, and the extent of the damages resulting therefrom. Once that information is compiled, counsel can help you determine what your options are for recovering your damages and getting your building fixed.
