Climbing up onto your roof only to see off-colored shingles can be very alarming. If you’ve seen this warning sign, you may have wondered to yourself, “If I have discolored shingles, do I need a new roof?”
The best way to tell if you need a roof replacement is by hiring a professional roofing company. We’ll go over the reasons why in this post.
What Causes Roof Discoloration?
Four main potential culprits could be causing the discoloration on your roof: algae, rust, moss, and age. All roofs will generally fade from sun exposure over time, but that doesn’t always mean your roof is healthy. The level of acceptable discoloration depends on the cause, the age of your existing roof, and the roofing material in question.
Algae and Moss
Accumulated debris, such as leaves or pine needles, can create areas where algae and moss thrive. While algae are relatively harmless to your roof as long as you clean it regularly, moss can cause serious problems.
Algae infestations are relatively easy to stop with the use of copper strips, which keep algae from growing in the first place. Our roofing contractors can install these strips for you if necessary. The best way to prevent mold growth is by removing debris and cutting down any branches that create the shade moss loves.
Rust and Age
Rust can appear on your roof if it uses copper strips to keep algae at bay. You’ll notice rust forming when red streaks begin to appear on your shingles. While red rust doesn’t pose any immediate threats to your roof, you should have it cleaned regularly by a certified roofer.
Finally, you may notice your shingles fading due to age. Asphalt shingles and wood shingles are notorious for showing age, but even metal and slate roofing can age over time. The only solution to an aging roof is repair or replacement.
Roofing Materials Play a Role: Asphalt Shingles, Metal Roofs, Etc.
Different roofing materials fall prey to various roof discoloration issues. For example, metal roofing tends to rust most over time, especially around roofing nails. Thick tile roofing can be particularly prone to moss, which can grow in its many cavities. A flat roof can be especially prone to sun damage and standing water.
Some roofing upgrades, like architectural shingles, are designed to last longer than their standard counterparts and may look nice for longer. However, it’s still important to schedule a roof inspection regularly. After all, all roofing eventually needs to be replaced with new shingles or other materials.
