Anyone used roof coating that actually works?

My roof has seen better days and someone told me about roof coatings that stop moss growing and prevent leaks? Is this worth it? How much would it cost for normal semi?

"No it sounds like an expense before having to have the job done properly. An average semi depending on materials, area, details would be £5k upwards

"Steer well clear, the whole process is detrimental to your roof and often causes damage. A re roof isn’t much more expensive anyway"

"A coating is ok for a repair, buy some black clean it off and spray it down it'll sort it right out"

"Yes, you can certainly do so. Providing the moss is removed using an anti fungal solution, then a clear coating or a colour coating pending on the condition of your roof. This benefits your roof as it’ll extend the life expectancy on your roof too."
