Why You Should Not Pressure Wash Your Roof

Over time, your roof can accumulate a layer of dirt, moss, algae, and lichen. These are not just unsightly; they are silent destroyers. Moss, for example, can retain moisture, leading to rot in wooden roof structures. Algae and lichen, on the other hand, can eat away at roofing materials, causing them to degrade faster than they should.

This build-up doesn't just affect the roof itself. It can lead to blocked gutters and downpipes, causing water to overflow and potentially lead to water damage within your home. In the winter, this can be exacerbated when water trapped by moss freezes, causing ice dams that can lift tiles and lead to leaks.

Moreover, a dirty roof is not just a cosmetic issue. It can significantly impact your home's energy efficiency. Dark stains and growths on the roof can absorb more heat, increasing the temperature inside your home and making your cooling systems work harder, leading to higher energy bills. Furthermore, the curb appeal of your home takes a hit with a neglected roof, potentially lowering your property's market value. A well-maintained roof is a sign of a well-cared-for home, something that is always attractive to potential buyers.

Regular roof cleaning is not just about maintaining the appearance of your home; it's about protecting its structural integrity, ensuring its energy efficiency, and preserving or even enhancing its value. In this blog we discuss why power washing, a seemingly quick solution, might not be the best approach for this crucial maintenance task.

The risks of power washing

While power washing might seem like a quick and effective solution for a dirty roof, its risks far outweigh its benefits.

1. Damage to roofing material

Power washing involves using high-pressure water jets. This intense pressure is often too harsh for roofing materials. It can lead to dislodging and even breaking of shingles or tiles. Particularly for asphalt shingles, the granules that provide weather protection can be blasted away, leaving the shingles vulnerable to the elements. This damage can reduce the overall lifespan of your roof. Continuous exposure of the underlying layers due to damaged shingles or tiles can accelerate wear and tear, leading to costly repairs or even a complete roof replacement sooner than expected.

2. Water penetration

The powerful stream of water can force its way under the tiles or shingles, an area it's not meant to go. This can result in leaks that are not immediately visible but can cause significant damage over time. These leaks can lead to water damage within your home, affecting ceilings, walls, and even the structural integrity of the house. The cost of repairing such damage can be substantial and far exceed the cost of proper roof maintenance.

3. Ineffective cleaning

Power washing may remove visible moss, algae, and dirt, but it often leaves behind the spores and roots embedded in the roofing material. These remnants can quickly regrow, meaning your roof might not stay clean for long. This superficial cleaning leads to a cycle of frequent and potentially damaging cleanings, as the underlying issue is never fully addressed.

4. Safety concerns

Using a high-pressure washer on a roof is inherently risky. The force of the water can cause a person to lose balance, leading to dangerous falls. The wet and slippery conditions exacerbate this risk. Roof cleaning should always be performed with proper safety equipment and expertise. Power washing without these can lead to serious injuries.

How professionals clean roofs

At Dazzle & Shine, we believe in a meticulous, gentle, and effective approach to roof cleaning. Our process is tailored to not only clean but also preserve the integrity of your roof. Here’s how our professionals handle the task:

1. Soft washing

Unlike power washing, soft washing uses a low-pressure wash system. This method significantly reduces the risk of damaging roofing materials while still effectively cleaning the surface. We use environmentally friendly and roof-safe cleaning agents that penetrate and break down the moss, algae, and dirt build-up. These solutions are specially formulated to target roof contaminants without harming the roof or the environment. The soft washing method allows the cleaning solution to seep into the nooks and crannies, ensuring a deeper and longer-lasting clean than high-pressure washing.

2. Manual removal

For larger growths like big patches of moss or nests, our team manually removes them. This careful removal ensures that all the large debris is cleared without any harsh scraping or damage to the roof. Each roof is unique, and so are its cleaning needs. Manual removal allows us to address specific problem areas with the right level of care and precision.

3. Preventative treatments

After cleaning, we apply treatments to the roof to prevent the regrowth of moss and algae. These treatments are designed to keep your roof cleaner for longer, reducing the need for frequent cleaning. This step is crucial as it adds an extra layer of protection, ensuring the longevity and health of your roof.

4. Gutter cleaning

As part of our roof cleaning process, we make sure that the gutters are not left out. Gutters clogged with leaves, twigs, and debris can lead to water damage and are often a breeding ground for moss and algae. Clean gutters are essential for proper water drainage. We ensure that all blockages are removed, allowing water to flow freely, which is vital for the overall health of your roof and home.
