Installing chimney flashing on a metal roof is a laborious business but if you love to work with your hands and you want to save some money on professional fees, you may want to try doing this carpentry job on your own. To help you install chimney flashing on a metal roof, here are some tips for you.

Prevent Bubbles on the Caulking

Before you attempt to install a new chimney flashing on your metal roof, you need to clean up the area where you want to install the flashing and make sure that it is smooth and dry. This way, it will be easier for you to install your chimney flashing and prevent possible bubbles on your caulking. Bubbles in the caulking can weaken your flashing so rainwater may find its way into your chimney and cause problems so make sure that you take precautions to prevent this from happening.

Pay Attention to the Overlaps

If you install a number of flashing segments, you need to overlap these segments at about 4 to 6 inches from the previous sheet to prevent gaps. Use metal screws or nails to hold the overlaps together then apply caulking material on the seams to seal them off. If you use nails to hold the overlaps, you should use a nail gun instead of a hammer to drive the nails into the flashing.
