WHAT NOT TO DO
DO NOT PRESSURE WASH YOUR ROOF. Pressuring washing your roof will wash away the surface of the shingles which acts as a protective layer shielding the shingle composite from sun exposure. Additionally, all that excess moisture being forced in between the shingles will fuel moss growth specially if the moss was not previously treated.
DO NOT WIRE BRUSH YOUR ROOF. Many less experienced contractors would use a wire brush to remove the moss off your roof which leaves your shingles in much worse condition removing the surface grains and reducing the lifespan of your shingles. Additionally, some contractors will jump straight into brushing which only removes the surface area leaving the roots of the moss to grow again from underneath the shingles which is the origin of the moss growth as that is where moisture is trapped. Think of trying to pull a live weed from your lawn compared to pulling a dead one, the dead weed will easy pul out as the roots have less hold, same applies to roof moss which is why we always do treatment first to kill the moss. Most of the moss will wash off within 10 - 12 weeks on its own without any unnecessary contact with the roof shingles.
DO NOT CHEMICAL TREAT YOUR ROOF WITH THE WRONG PRODUCTS. There are many products to treat moss in and around your lawn however when it comes to your roof, it is important to use the proper measurements for your solution depending on the type of roof to make sure your shingles don't dry out and wrinkle up and your cedar shakes don't get discoloured and chip. The main purpose for using chemical compounds is to change the pH levels of the roof environment to either basic or acidic. While both kill moss, an acidic formula for example would dry out the shingles and cause them to wrinkle as opposed to a base formula.
