There is a way! I would open slide fully and install a nail or cotter pin in the end of roller, then remove fabric. There is a screw in the gutter than has to be remove before fabric can slide out. Then with fabric removed, you remove the pin in the end and add 2 or 3 additional turns, add pins once again. Then reinstall the fabric and gutter screw. Not to time consuming and would like to do mine also. Ours seem to either be stretching or roller springs getting weaker. This is a two person job!!!!!
