Your roof is one of the most expensive elements of your home. A complete replacement costs between $15,000 and $40,000. Regular preventive maintenance can delay this replacement by 10 to 15 years.
The recommended maintenance schedule
Every year: Visual inspection from the ground. Gutter and flashing check. Trimming of branches overhanging the roof.
Every 3 to 5 years: Professional Soft Wash cleaning with SH + surfactant. This is the optimal frequency to prevent permanent organism establishment.
After each severe winter: Flashing inspection, checking for shingles displaced or lifted by ice.
Trees: the main risk factor
The presence of trees above or near the roof accelerates buildup. Leaves retain moisture, branches create shade (ideal conditions for moss), and bird droppings from perched birds transport spores. Maintain your trees well-trimmed and a minimum distance of 10 feet between branches and the roofing.
