Discoloration on your roof can indicate different things. Stains come in different colors, but not all are signs of significant damage. Their location and color of stains usually determine what causes them. Moreover, these marks can affect the appearance and curb appeal of your home, meaning you want to get rid of them as soon as possible.
Keep on reading for a quick guide on roof stains from a trusted new roof construction company.
Roof Stain Colors: What Do They Mean?
Yellowish or White Roof Stains
White or yellow stains on your roof is a sign of hard water buildup from your evaporative cooler or air conditioner. You can usually find these stains on the lower parts of the roof underneath cooling units, and they are quite noticeable. If you have this kind of stain, keep in mind that power washing is not a good idea and will only do more harm than good. A vinegar solution should reduce the appearance of stains without causing harm to plants or animals in your home. As much as possible, do not use harsh chemicals for removing stains because they can be dangerous when not handled properly.
Algae or Green Roof Stains
The presence of algae or moss can result in black or green stains on your roof. High moisture levels and sunlight create the perfect environment for the growth and reproduction of these microorganisms. They can cling to moisture and cause bigger creatures to settle on your roof. Again, power washing will not completely remove them and risks your roof of severe damage. For this problem, it is best to contact a reputable roofing company. An experienced professional knows how to remove these stains without causing damage to your roof.
Brown or Red Roof Stains
Metal roofs become prone to rust as they age. It is just one reason to get regular inspection and maintenance from professionals regularly. Red or brown stains on your metal roof can indicate the development of rust. This problem can be caused by issues with a metal chimney, flashing, or other metal components of your roof. You would need to have any rusted roof flashing checked to make sure they do not cause leaks in your roof. It is the same for metal chimneys, which should be inspected for holes.
Your roofer will need to locate the source of the rust to halt the flow of iron oxide. Typically, rust stains can be dealt with vinegar or oxalic acid. You can delay the need for a metal roof replacement by dealing with these stains while they are not widespread.
Black Roof Stains
Black stains may develop across an asphalt shingle roof when it is nearing or has reached the end of its life. An inspection from an experienced contractor can help you determine if this is the case. As asphalt shingles deteriorate, the black pigment from the asphalt rises to the surface. Experts call this phenomenon asphalt bleed-through. Algae stains and asphalt bleed-through can look quite similar because they both look dark. When you notice black spots on your roof, immediately contact your contractor to find out if your system needs replacement.
Other Things Causing Roof Stains
Parts of your roof that are under trees may have stains on them due to seeds, berries, branches, leaves, and other decaying debris. Moss usually develops under the shade of trees, so also watch out for it. It is normal for roofing shingles to lose granules as they age. Dark-colored shingles can look lighter and patchy when they are approaching the end of their lifespan. Check your gutters if there are a significant amount of asphalt granules. If so, you may need to get a new roof soon.
Tips for Preventing Roof Stains
Keep Your Roof Clean
Regular roof maintenance goes a long way when it comes to preventing roof stains. By making sure that there is no buildup of leaves, dirt, and animal droppings on your roof, you can prevent moss and algae from growing. Invest in regular cleaning from a professional to keep dark stains from developing on your roof. Cleaning is also the easiest way to prevent rust from occurring on your roof.
Get Regular Roof Inspections
Routine inspections from a residential roofing company can help prolong the life of your roof. It can help issues like stains from occurring. You will not only save on costly repairs and replacements but also on your energy costs. An efficient roof can help keep you comfortable while reducing the load of your HVAC system, which helps lower your utility bills.
Give Your Roof More Sun
To expose your roof to more sun, trim down surrounding trees around your home. Excessive moisture is the main cause of mold and algae growth. The more sun your roof gets, the faster moisture evaporates, helping prevent the growth of these microorganisms.
Clean Your Gutters Regularly
Another thing that helps is regular gutter cleaning. Clogged gutters can cause rainwater to back up to your roof and encourage mold growth. When water does not drain properly through your gutters, you may also end up dealing with siding and foundation damage as well as basement flooding.
Invest in a Roof With Rust-Resistant Coatings
When getting a metal roof replacement, it pays to choose a material with rust-resistant coatings. You can determine how rust-resistant a roofing material is through the manufacturer’s warranty. Usually, the longer the coverage of the warranty, the more protected the material is against the elements.
Get Zinc and Copper Strips
Zinc and copper strips are one of the most effective ways to prevent algae growth on your roof. Today, some shingles are infused with copper for improved moss and algae resistance.
