Quick “Pipe” Block is the answer to this problem. This UV protected block rides on a styrofoam pad to protect the roof from the expansion and contraction due to the varying temperatures. This greatly reduces the possibility of roof membrane failure.

The Quick “Pipe” Block is constructed out of high density polyethelyne with a UV additive to ensure long life.

This unique product is manufactured and distributed by Nelson - Olsen, Inc. and is available at your local wholesaler. Quite economical, the Quick “Pipe” Block reduces non-productive time by eliminating trips to the lumber yard for wood blocks, preparation time, and allowing for one stop shopping.

It is stable, sheds rain and snow, will not deteriorate overtime, and is recyclable. The block measures 12”L x 6”W x 31/2”H, with a 3/4” styrofoam pad.


Wooden blocks carrying pipes on rooftops have long been a source of problems for roofs. Not only do wood blocks deteriorate over time, but eventually rip the roof membrane due to the constant expanding and contracting, from temperature fluctuations. This can lead to expensive repairs because of leaks.

Now there is a solution to this problem.

Typical deterioration of wood block construction that eventually causes roof membrane rips.
