What is algae (or fungus) found on roofs?
In some moist areas, algae can grow on shingles. Although the algae has no proven effect on shingle life, it does stain or discolor the shingle. Commonly called fungus, this algae staining can be unattractive. The algae-containing stains can be dramatically reduced by the use of special copper granules. Call Hansons’ to answer your questions.
What are ice dams?
The typical ice dam is a buildup of ice that forms near the eaves or gutters as a result of interior heat escaping into the attic and through the roof decking. The heat melts the snow and ice on the upper areas of the roof resulting in meltwater. This melted water runs to cold, lower areas or eaves and depending on the conditions refreeze.
