When the outside becomes treacherous, a solid roof is your first line of defense against the elements. You can imagine how disheartening it is when the protective covering of your home starts to change in appearance—a clear indicator that your roof is feeling the impact of inclement weather over time. Water is among the most common causes of aging in a roof, leaving unsightly moisture stains that threaten to compromise the security of your house if left untreated. Consider the color of water stains and extent of damage when coming up with a solution for your roof.
Black or Green Roof Stains
Black or green water stains on your roof indicate growing organisms, such as algae or moss. The presence of constant moisture and sunlight makes for a delicious and cozy harvesting area for such microscopic tenants. They can lock in unwanted dampness or invite other, larger creatures to wreak havoc on the top of your house. Power-spraying or scrubbing the problem on your own is possible, but likely to cause further, irreparable damage.
White or Yellow Roof Stains
White or yellow discoloration on your roof suggests hard-water buildup from an air conditioner or evaporative cooler. This type of staining often occurs on lower areas roof beneath cooling units and sticks out like a sore thumb. Similar to algae-type staining, attempting to scrub or power-wash will probably make things worse. Rather, you can try fading the damage with a vinegar solution, which works to gradually dull mild stains without risk to the plants or animals around your home. Be careful of any harsher home remedies, as they can become dangerous if mishandled.
When in doubt, professional roofing companies are better equipped to eradicate roofing stains with special chemicals, sealers or new repellent shingles when necessary.
