Choosing a roofing material for your home can be a cost-intensive exercise and you need to factor in some things when making a decision on your home's roofing system. You will want to choose roofing materials depending on their qualities, pros and cons in order to find the best option that will give you value for your money. If you have decided to go for asphalt roofing, perhaps because it is one of the least expensive roofing options, you should know that this type of roofing might be susceptible to occasional mildew, algae, and moss. Algae and moss will not only lead to an unsightly appearance of your roof, but can also cause lifting or curling of the leading edges of the asphalt shingles and affect their reflective performance.
Here are tips you can use to prevent this.
Trim the Branches of Trees near Your Roof
If you have some trees near your roof and these trees are growing over the roof, consider trimming any branches that may be touching the roof. First, trimming the branches will ensure that more sunlight is reaching your roof. Branches can also contribute to the accumulation of dirt and debris on the roof. Therefore, clearing the branches will create a less inviting environment for the growth of the algae or moss.
Gutter Maintenance Is Key to Effective Water Drainage
A poorly maintained gutter can also provide the perfect environment for the growth of moss and algae. Therefore, clean your gutters regularly to prevent accumulation of dirt that may interfere with the water drainage. In addition, make sure that the gutter on your upper roof doesn't drain onto your lower roof directly. You can do this by extending the downspout from your upper roof into your lower gutters.
Improve the Flow of Air on Your Roof
The flow of air on your roof can also affect the suitability of the environment for the growth of algae or moss. Therefore, consider directing the flow of air down the slope to prevent dirt and other debris finding its way under the edges of your roof shingles.
Clear Dirt and Debris from Your Asphalt Roof
This is a simple regular maintenance approach that you should consider on your asphalt roofing. Regular cleaning of the roof using non-abrasive measures such as a leaf blower should help you keep your roof as clean as possible to prevent growth of moss and algae.
