Starting in 1995, siding contractors in Portland, Vancouver, and other Northwest cities began to see sporadic LP Siding replacement jobs that involved badly delaminated LP Siding. However, the number quickly grew. While replacing LP siding, residential contractors began to notice a mushroom-like growth on the bottom edges. This became a serious concern as more and more LP Siding replacement jobs popped up and LP siding started began to appear in newspapers and in the courts; siding contractors began to look into what was happening with LP siding and why.

When Louisiana Pacific’s “cutting-edge” composite siding hit the market in 1985, it was hailed as a revolutionary type of siding that went on quickly, would last a lifetime, and was affordable. However, starting in 1993, homeowners in the Pacific Northwest began to notice that the bottom edges of their lap siding had turned black, the layers of the boards were coming apart, and there was a mushroom-like growth thriving on the siding. Repainting did little to help the situation; the black stains appeared to seep through and the growth quickly returned in a matter of months.

It was discovered that the black stains and mushrooms were a fungus and that LP siding was an ideal environment for it. What made it so ideal? Louisiana Pacific siding is little more than excess lumber which is ground up, mixed with glue, and run through a press; this a perfect environment for fungal growth. The problematic fungus was also part of the package, as it was already present in the wood when it was ground up. Louisiana Pacific received most of the notoriety for this, but several other companies like Georgia Pacific, Masonite, Clad-Board, and Weyerhauser used the same idea for their composite siding products.

The LP siding problems hit the Pacific Northwest first, in large part because of the amount of rainfall that the region receives: moisture and warmth added to the ideal conditions for fungal growth. Other states in the South like Georgia are experiencing similar LP Siding issues.
