How can I get the moss off my roof?

Question

The shingles have a lot of moss due to lack of sunlight and too much dampness......too many trees (that I will soon have trimmed). Is there a cleaner or some method I can use to get the moss off?

Answer 1

previous answers here with bleach and water is the way to go... however it might be worth the effort to carefully pull up a couple of the stronger looking affected shingles to make sure that the water necessary for growth of the moss has not penetrated into the sub-roof sheeting.. if the plywood has been wet too long.. there is more damage there than bleach and water can possibly fix.. hopefully you can remedy the situation soon enough to avoid having to replace the roof :P good luck

Answer 2

Go to HOME DEPOT they rent pressure washers by the hour and by the day. There in the paint dept (where they keep the pressure washer solution) there is a chemical to take the moss off. WARNING do NOT put bleach in the pressure washer (some can most can't) it will eat out the o-rings and you will be stuck with an expensive repair bill.

Answer 3

I have heard that a strip of magnesium may also be located alongside the roof ridge. When it rains the water includes a bit magnesium down the shingle, making it wrong for moss to develop right here.

Answer 4

The best method I found is to take a presure waher with a mild bleach solution like three parts water to one part bleach this will remove the moss and kill any new growth. It worked great on my friends house and barn.

Answer 5

a mixture of bleach and water will kill it but you'll need to shovel or pressure wash the base it was growing from usually dirt and dust collected as it grows until you have a soil like base.

Answer 6

Yes....A pressure washer! They work great...not that expensive either plus you can then use it on your patio and driveway!!
