Step-by-Step Instructions for Cleaning Roof Shingles

Choose a cloudy day that is not very warm. Cleaners may evaporate too fast in direct sunlight and become less effective.

2. Prepare the Area

Wrap plastic sheets around cover plants and outdoor furniture. Ensure that gutters are clean to capture runoff.

3. Mix Your Cleaning Solution

Apply a solution of half water and half bleach or a roof cleaner commercially available, a biodegradable cleaner.

4. Apply the Solution

Apply the solution on the affected areas using a pump sprayer to cover the areas uniformly. Begin at the lowest level and go up.

5. Let It Sit

Let the solution rest between 15-20 minutes to allow the solution to dissolve stains and organic growth.

6. Gently Rinse

With your hose on a low-pressure setting, rain the roof downwards. Be sure not to spray upwards, as this can lift shingles.

To remove stubborn growths or stains, scrub lightly with a soft brush and rinse thoroughly twice.

What Cleaning Solutions Are Safe for Asphalt Shingles?

Asphalt shingles consist of a fiberglass or organic base that is covered with asphalt and granules. Strong chemicals or unreasonable force may make the asphalt weak and lose its protective granules, and damage the waterproof layer.

• 50/50 Combination of Water and Bleach (Sodium Hypochlorite):

This dilute solution is effective in killing biological growths such as algae and mold without deteriorating the asphalt or granules, provided it is well diluted and thoroughly rinsed.

• Environmentally-Safe Roof Cleaners:

They are formulated to be non-corrosive and biodegradable, and thus they are not harsh to roofing materials and also are not harmful to the environment, particularly when the runoff finds its way to your landscaping.

• Store-Bought Cleaners that are non-corrosive:

Specifically manufactured products used in roof shingles are subject to tests that guarantee their compatibility with asphalt products. They’re usually pH-balanced, and they’re solvent- or acid-free.

Avoid:

• Undiluted bleach
• Ammonia-based cleaners
• Abrasive detergents
• Acidic or solvent-based chemicals

Soft Wash vs. Pressure Wash: What’s Better for Your Roof?

Selecting an appropriate washing technique is imperative in extending the life of your shingles.

Soft Wash

o Utilizes low-pressure water (less than 500 PSI) and cleaning chemicals
o Safe for Asphalt shingles
o Delegates algae, moss, and stain elimination efficiently without damaging the surface
o Most roofing manufacturers recommend it

Power Wash

o Employs high-pressure water (greater than 1,000 PSI)
o Can remove granules from shingles and reduce the life span of roofs
o Should not be used on asphalt shingle roofs except in very mild and limited ways.

Verdict: Whenever cleaning asphalt shingles, always use soft washing. It is safer, less intrusive, and more conducive to the durability of roofs.

Common Mistakes in Roof Shingles Cleaning

The idea of cleaning your roof shingles might be simple enough, but many people fall into the common traps of causing more damage than good. No matter how minor they might seem, whether through incorrect methods or neglect of certain essential matters, such errors can and will diminish the life of your roof, cause you to spend hundreds or even thousands of dollars in repairs, or even allow your warranty to become nullified. It is also crucial to know what to avoid doing in the process of cleaning as much as it is to know how to clean properly.

Using Harsh Chemicals or Bleach Improperly

The belief that the stronger the better is a thought process that many homeowners utilize when it comes to using undiluted bleach or acidic cleaners, which can degrade asphalt shingles and remove protective granules. Gutters, landscaping and underlayment can also be ruined by overuse or improper mixtures.

Overpowering With High-Pressure Washers

High-pressure washers used on shingles may loosen or dislodge granules, curl edges and drive water, enabling it to get underneath the roofing system. The outcome usually turns out to be accidental water leakage and early roof death.

Ignoring Mold, Algae, and Mildew Growth

Black lines and green spots are not only an aesthetic problem, as they indicate the growth of algae or mold. Neglect of the same may result in permanent damage, moisture accumulation, and deterioration of the shingles. Regular checkups and mild cleaning keep the roof in shape.
