My husband and I wanted to add an addition to our home for years before we finally decided to act on the idea. However, we then realized that we desperately needed to update our kitchen, as well. Before we started the remodeling process, we prepared for what we expected: stress. We made sure we cleared our calendars and didn't have any other major commitments during the remodeling process. However, once we began planning the renovations, we quickly learned that we were actually having a lot of fun! The renovation process also went very smoothly and, now that the process is over, we both joke around that it feels "too quiet" in hear without the company of the contractors. I enjoyed t all so much I decided to start a blog to share my remodeling tips to help others who will soon be taking the plunge!
Sometimes rooftops can get covered in black streaks. Some areas of the roof may be more susceptible to black streaks than others, and some rooftops are more vulnerable to black streaks than others. Knowing what the black streaks are, how you can get rid of them and how you can prevent them from coming back in the future can help you preserve the appearance of your house.
What causes a roof to get covered in black streaks?
Black streaks on a roof are generally caused by algae growing on the shingles.
Does algae do damage to a roof?
Algae cannot cause a roof or roofing materials like shingles to deteriorate. All damage caused by algae is cosmetic in nature.
Can the algae be removed from a roof?
To remove algae from your roof, spray it with a combination of bleach and water. You may use either chlorine bleach or oxygen bleach. If you choose to use chlorine bleach, water the plants around your home before spraying down the roof, then water the plants again after spraying down the roof. This will help prevent the plants around your home from absorbing the chlorine bleach.
If you use oxygen bleach, you will not need to protect the plants around your home because oxygen bleach won't kill shrubs. Once the algae on the roof has been whetted by the bleach and water combination, use a long-handled plastic scrubber to scrub the algae off the roof.
When the algae has been scraped off the roof, use strong jet of water from your garden hose to rinse the shingles. Do not walk on the shingles and do not spray the shingles with a power washer. Doing either of these things could damage the roof. Use a ladder to access the roof.
How can you prevent the algae from returning to your roof?
Algae thrives in wet, shady environments. Pruning any nearby overhanging trees will help keep your roof dry and will also help sunlight reach your roof shingles, which could make your roof a less inviting environment for algae. If this doesn't work, you can also nail copper flashing strips underneath the top layer of shingles along the roof ridge. When rain water runs down the roof over the copper strips, the ions that the water picks up from the copper will prevent the algae from growing.
The next time you get a new roof, have your roofer install algae-resistant shingles. This is one of the best ways to prevent algae from growing on your roof.
