Proper preparation is the key. Power wash, then scrub with TSP & a long handled brush. Then rinse well. This gets rid of all the loose dirt and any grease on the surface. Repair damaged areas. Reset any loose nails. Use a vibrating sander to take the edge off the old paint. Spot prime areas that need it. Calk with a paintable calk. Repair/replace any flashing. Then paint.
