cleaning shingle roof

If you want to keep your shingle roof looking its best, you should use non-corrosive cleaners. These include Bleach, Vinegar, and Copper. However, these solutions should be rinsed off after fifteen to twenty minutes. Rinsing is crucial to preventing further damage to your roof. Before using these products, check the weather forecast to find out the best time to clean your roof.

Non-corrosive cleaners

When cleaning your shingle roof, it’s important to use a non-corrosive cleaner. If the solution is too harsh, it can damage the shingles or nails holding them. It can also dissolve the glue that keeps the shingles in place. To avoid these problems, look for cleaners that are biodegradable and don’t contain bleach or sodium hydroxide.

When cleaning your shingle roof, you should water it first to make sure the cleaner does not dry out on your roof. Then, spray the cleaner onto the shingles and let it sit for about 20 minutes before rinsing it off.


One of the easiest ways to remove algae, moss, and stains from your shingle roof is to use a bleach solution. You can mix the bleach with water in a 50:50 ratio and spray it onto the roof. Leave the mixture on for 15 to 20 minutes, then rinse it away with water. Any remaining algae and moss will fall off due to rain and wind.

However, it is important to remember that bleach is a potentially toxic chemical and should only be used by professionals. You must follow safety procedures when handling it, including wearing protective eyewear and gloves. You also need to ensure proper ventilation.


When you want to maintain a shingle roof that looks clean and is free from dirt and moss, try using a mixture of vinegar and water. This solution is inexpensive, easy to find, and does not contain any harsh chemicals. It can be used alone or combined with dish soap for a powerful cleaner. Vinegar is safe to use on shingles, as it does not damage nearby paint or landscaping.

If you want to remove mortar and other stains from your shingle roof, you can use muriatic acid to do so. However, be careful, because this acid is toxic to the eyes and skin and will damage your building and the plants below it. Always start with the mildest solution, like vinegar, before working your way up.


You can clean your shingle roof with copper granules. These strips will keep the roof clean by killing algae on the shingles. They can also help you prevent algae stains on your roof if you have copper flashing. But before you use these strips, make sure that you have purchased those with the best warranties.

First, you should make a cleaning solution that consists of three parts lemon juice to one part coarse salt. For a copper roof, this will require six cups of lemon juice and two cups of coarse salt. You may need to make several batches to clean your roof thoroughly. After you’ve mixed the solution, you should sweep the roof to remove loose debris. Don’t scrub the copper, as it will leave a messy mess.


Zinc is a great choice for cleaning a shingle roof. The antimicrobial property of zinc helps prevent mold and algae growth. This metal is used in roof cleaning products that are commonly found at home improvement stores. However, it’s important to note that zinc-plated materials can rust after a few years.

Zinc is usually sold in powder form. To apply it, spread the powder generously over the mossy areas. You can also use a soft-bristled scrub brush to remove moss. It is important to do this slowly and gently so as not to pull the shingles off. Applying this material regularly can prevent algae and moss from growing on the roof for up to three years.

Copper strips

Whether you want to clean a shingle roof or are planning to replace your shingles, you might be wondering how to clean a shingle roof. While the process is relatively easy, you may want to call a professional roofer for the installation of copper and zinc roof strips. These are best installed on a brand-new roof and are most effective when the roof is clean. Before installing copper and zinc roof strips, you should first clean your shingle roof.

A copper or zinc roof strip will help eliminate algae on your shingle roof. These metal strips contain algae-killing molecules. However, they do not offer 100% protection. Winds can still break the sealant bond and cause leaks.

Roofing contractors

Shingle roofs are one of the most common types of roofing materials. They are durable, lasting up to 20 or 40 years before showing signs of wear. Typically, the first sign of deterioration is algae or moss growing on them. However, cleaning a shingle roof can be a complicated process.

Roofing contractors clean shingles using chemicals that are safe and effective for roofs. One of the chemicals they use is sodium hydroxide, which is a highly alkaline substance. It also breaks down the petroleum-based components of asphalt. It is also effective at cleaning slate roofs.
