There are hundreds of potential siding related problems. Most of you visiting this site might be familiar with the obvious ones such as defective Louisiana-Pacific siding or hazardous asbestos shingle siding. However, siding problems could be the result of poor installation, extreme weather exposure, improper nailing, inadequate flashing, poor paint coverage, inappropriate caulking, fungal growth, or delayed maintenance. These are just a few samples of what might be causing your siding problems. The bottom line is you have a problem that needs to be addressed before it leads to more significant problems, costs, or headaches.

What is composite wood siding?
There have been well over 100 different types of wood composite sidings manufactured in the last fifty years. They have been manufactured to look like horizontal lap siding, panel (T1-11) siding, board & batten siding, cedar shingle siding, and just about anything else available in real wood.

Most wood composite siding products are made with wood by-products such as Orientated Strand Board (OSB) (also known as Wafer Wood) or sawdust. The by-products are generally mixed with resins and pressed together to make panels typically 3/8″ to 5/8″ thick. Next, faux wood-grain embossed overlays are adhered to the face of the panels with resin and heat. Finally, the large panels are cut into smaller panels or lap siding.
