Jims is right they are mean little buggers.
hope this is not to late and hope it may help.If you look where those wittle feet are planted(take a closer look)some will be inbetween the paint and brick,betwwen the brick and point and when it gets to the wood it will be between the paint and wood.If you try to pull them off ya take paint off in spots,makes a job look bad.Inform the home owner it may happen,then try this,Cut and pull some of it off slow-e,go ahead and pw the rest off but do not deep clean the roots if they break off at paint level do not go no more.In a day or 2 ever you are the home owner can do some small touch up painting(need pointed brush).Tell this to the home owner or price it in your bid.If ya try to get that wittle root off paint ya going to take or may take alooot of paint off in spots,making ya job look bad...........Adios
