Two Step Process:
Cleaning and Preserving

Step 1. Powerclean: Before any powerwashing is performed your cedar roof is treated with a weathered wood restorer. This product counteracts the weathering process by eliminating dirt, fungus, and discoloration of the cedar. Using pressured water alone to clean the wood would require dangerous amounts of pressure which could cause damage to healthy wood. Along with the wood restorer a thorough powerwashing removes dirt, mildew, mold and dead wood fibers bringing the roof back to a rich "new" wood appearance. This step is essential for the wood to successfully absorb the preservatives. The powerclean step is not necessary with newly installed roofs (generally up to 3 months of age).

Step 2. Treatment: The application of Amteco's TWP 200 series wood preservatives designed for cedar shake and shingles. TWP 200 Series gives complete protection against moisture and sunlight and helps protect your roof from cupping, curling, cracking, and splitting. We offer 7 natural cedar shades ranging from Cedartone to Weathered Gray. (see product data sheet)
