Roof moss begins with a thin dusting of green that you may notice only from low angles. This thin layer on the top of the shingles gradually expands and becomes wide, thick, and mat-like. The seams between the shingles and the shingles’ edges also develop moss because they tend to be especially shaded.

As moss thickens, it works its way under the shingles and raises them up. If the shingles are wood, this process can happen at an alarming ratewood’s porous surface is prime real estate for moss growth. Once moss has adhered to wood shingles, it is much harder to remove than from the relatively smoother planes of composite or asphalt shingles.

Once the moss is a thick mat, it becomes a sponge that soaks up and retains all moisture. This stored water quickly works its way under and between shingles and then onto the lower levels of roofing felt and the structural elements of the roof. This eventually leads to rot, and rot leads to further decay of roofing materials. The accelerating cycle can even destroy a roof in a matter of a few months.

Grass requires ample sunlight so if your lawn has too much shade, it will not grow well.

If you live in a humid area of the country, youve probably seen unsightly dark streaks on asphalt shingle roofs. Though often attributed to an accumulation of dirt, defective shingles, mold, or mildew the most common culprit is actually a blue-green algae known as Gloeocapsa Magma that is spread by airborne spores.

A professional roofer has the experience to remove moss and repaint your roof safely, and they are much better at spotting signs of wood rot or leaks under your roof.
