Your roof's gutter system is an important part of its protection against
water damage like roof leaks that may crawl to your ceiling and walls. It also
keeps your yard safe from water that may flow from the roof due to runoff.
Mildew that grows on your gutter system do not only create an ugly sight, they
can also create health issues. To protect your gutter system, here are some
ways to remove mildew that may have grown on it.
Wash your gutters to rid them of leaves, twigs, loose grime and mildew.
You can use either an ordinary hose or a pressure washer for this. For large
debris like fallen branches, use a garden trowel.
Make a mixture of one part bleach and four parts water solution and use
this to scrub the gutter surface. This should kill most of the mildew. You can
use environment-friendly cleaning solutions like vinegar instead if you have
plants in the immediate area that might be affected by the bleach solution. Use
an extended gutter brush or your car brush to reach the downspouts.
Be sure to rinse the gutter properly using clean water. Check regularly,
preferably after one week, and every other day afterward, if the mildew has
returned. If so, you might want to contact a professional contractor to check
out your gutters.
