The DIY roof window kits come with nearly all the hardware needed to assemble. Please verify what type of roof you are dealing with before installing it. If necessary, you may need to use electric drill, saw and hammer other than those included in the enclosed installation kit. Consult a licensed contractor for installation hardware recommendations. Do not use cleaners containing solvents or abrasive cleaners on polycarbonate sheet and metal. Use only a mild soap and water solution with a soft, non-abrasive cloth.
