Why Do Mosses Grow on My New Roof in Hamilton?
Moss on the surface of a new Hamilton roof can be annoying, but moss develops for various reasons. Why moss develops is the best prevention. The major reasons for this are:
1. Humidity and Moisture:
Hamilton’s frequent rains and wet climatic conditions support the best environment for the growth of moss. Wet conditions are the favorite for moss, and the continuous humidity around the area is the best for its thriving. Wet climatic conditions support the needed water for the growth of the moss, making the scenario common for house owners.
2. Shady Spots:
Moss prefers shade. If your roof is under trees, the chances for moss will be increased. A lack of sunlight extends wetness here, and the moss will grow. Branches over the roof shade the sunlight, creating cool, wet places where the moss can grow uninterrupted.
3. Roof Surface:
Certain roofing materials like the asphalt shingles hold water. Moss will grow easily where the surface is uneven and porous. New roofs made from these materials are vulnerable, for the roofs can retain rainwater. These materials’ surfaces are the best for the moss spores to settle and grow upon.
4. Poor Drainage:
Inadequate drainage will cause the water to accumulate on your roof. Sustained draining points or ponding create the best setting for moss to grow and grow. Gutter blockages or improper gradients will exacerbate the situation by causing the moss to grow continuously.
5. Organic Debris:
Leaves, branches, and debris collect on your roof. Debris provides a habitat for moss and algae by retaining the wetness and providing nourishments. It decays over the years and produces the optimum environment for the establishment of moss. Debris is not accumulated by the routine cleansing, and the opportunities for the establishment of moss are thus ruled out.
6. Temperature Variations:
Moss thrives in temperate climates to mild climates. Perfect conditions for moss are provided by the warm summer and cool winters of Hamilton, where the shade and shelter retain the moisture. Moss can grow year-round under a moderate climate, especially where the light is not much. Moisture and light exposure need to be under control for the prevention of moss growth.

1. Trim Overhanging Trees
Overhanging trees shade your roof, leaving the surface wet. Periodically pruning the branches allows the sunlight to evaporate the roof earlier.
