Maintenance Tips


Never Block Off Roof Ventilation
Under no conditions should you ever block roof venting. Ridge, soffit and fascia vents must remain clear all year round. Louvers and roof ventilators should remain functional at all times.

Keep Your Roof Clean
Remove any debris that builds up on your roof, including leaves, branches and evergreen needles. Use a stiff broom or brush to remove accumulated debris, especially from between the shingles or shakes. Remove any branches from nearby trees that touch or scrape the roof.

Moss Control
During dry weather, control moss by spraying or brushing the affected area with a 10% solution of zinc sulfate. Alternatively, you can use a solution of one part household bleach to four parts water. The dry moss absorbs the solution, thereby killing it. The dead moss can eventually be swept off the roof.
Mold and Mildew Control
Mold and mildew can be killed and cleaned from cedar shingles using a solution made of 3 ounces trisodium phosphate, 1 ounce detergent, 1 quart 5% sodium hypochloite in 3 quarts of warm water. Apply the solution to the affected area and scrub with a soft brush. Rinse thoroughly with water.
Since these chemicals are toxic, take special care when using them. Avoid contact with surrounding plants and the soil. Using only as much as needed to do the job will minimize any impact on the surrounding landscape.
