Roofing for the Here and Now The roofing industry has changed quite a lot over the years. These days, homeowners are rarely opting for the standard, 3-tab shingles that were so popular a few decades ago. Instead, they are going with architectural shingles, and in some cases, with even more eco-friendly options like green roofing or slate. Whether you're shopping around for a new roof or are thinking of having repairs made to your current roof, it pays to be educated. Learn the basics on this blog, where we discuss roofing in the modern world. We explore various roofing materials, roofing techniques, and how to find the right roofer.



Asphalt shingles are a common roofing material. They are durable, beautiful, and excellent at keeping the harsh weather elements away from your home. However, the shingles may become affected by water and moisture over time, leading to unwanted growths on the roof. 

Algae are common growths you may experience when you fail to perform proper maintenance. Here is what you need to know about having dark streaks on your roof and why you should call a roofing contractor for immediate repairs. 

The Possibility of Removing the Dark Streaks

Generally, the discoloration caused by algae is difficult to remove. However, you can attempt a few home remedies to clean it up. One of these remedies is a mixture of chlorine bleach and water. 

Even so, it is advisable to hire a professional roofer for the cleaning process. Naturally, a roof that has algae is quite slippery. The good thing about hiring an expert roofer is that they will conduct the cleaning process using protective clothing and safety equipment to avoid falls and other injuries. 

Mistakes to Avoid When Clearing the Stains

You can clear the algae stains from your roof using the right tools. Nevertheless, you should avoid scrubbing it using power-washing equipment. That's because power washing removes the granules on the roof's surface and hence shortens its life.

The Effect of Algae on the Shingles

Mostly, the presence of algae impacts the aesthetic appearance of your home by making the roof an eyesore. Additionally, algae growth could signal a deeper underlying problem that you need to fix. 

For example, since algae develop in moist environments, the stains should be your cue to prune the trees close to the roof and repair or replace your gutters. Besides that, they may indicate a need to have the roof inspected for water and moisture accumulation. 

Getting Algae Resistant Roofing Material

Preventing algae growth shields you against costly repairs and unnecessary losses. The best way to achieve this is by installing shingles containing copper-lined mineral granules. These shingles incorporate copper as an additional element, and they exhibit algae inhibiting properties. If unsure of the best material to purchase, consult your roofing contractor. They will advise you about products that can counter the effects of green algae and moss in your home. 

Getting rid of algae from your roof is essential in preventing roof deterioration. So, hire a reliable roofing contractor to inspect the spread and determine the most effective way to clean it up.
