Got Moss? Why pressure washing it away, will eventually make you pay.

Alaska Moss on Roof in Anchorage


Protecting Your Warranty

When moss starts invading your roof, it can be tempting to grab the pressure washer and blast it away. Seems like a quick fix to restore your roof's appearance but, before you pull the trigger you may want to consider the outcome. Pressure washing your roof can completely void your warranty!

Using high-pressure water to remove moss not only strips away important coatings on your shingles, but it likely does not align with roofing maintenance guidelines. In fact, some warranties explicitly state that pressure washing is prohibited.

According to ARMA (asphalt shingle manufacturer association), anything over 300 PSI will void your warranty. The intense force of the water can damage shingles, tiles, or other roofing materials. Additionally, the high pressure can force water underneath the shingles, leading to leaks and structural damage. If you ever need to file a warranty claim for roof repairs, the manufacturer may deny it if they determine that pressure washing contributed to the damage.

Instead of risking your warranty, consider alternative methods for moss removal that are approved by roofing experts. Our Soft Wash process is the only ARMA approved method and won't jeopardize your warranty coverage!

Addressing the Root Cause

Sure, pressure washing might blast away the visible layer of moss, but it's just giving it a haircut. You need to address the root of the problem for longevity and health of your roof. Moss thrives in damp, shaded environments, and simply removing it without addressing the underlying conditions won't prevent it.

Moreover, as we previously discussed, pressure washing can actually make matters worse in the long run. The force of the water can dislodge granules from asphalt shingles, further accelerating their deterioration. As the protective granules wear away, your roof becomes more vulnerable to moisture penetration and moss growth.

Instead of resorting to temporary fixes, investing in professional solutions will lead to long term prevention and peace of mind.  It is important to properly vet the company you choose, that they are using an approved softwash process. We safely and gently remove the heavy moss and treat the roof with our solutions to kill off growth lasting for years to come!

Long-Term Cost Considerations

While pressure washing might seem like a cost-effective solution for removing moss from your roof, it could end up costing you more in the long run. It's easy to just hook up a sprayer and go for it, leading to quick satisfaction. While at the same time, leading to the need for costly repairs or premature replacement.

Each time you pressure wash your roof, you're essentially kicking the can down the road rather than addressing the root cause of the issue. The temporary nature of pressure washing means that you'll likely find yourself facing the same moss problem again in the future. 

Investing in proper moss prevention methods can save you money over time. On average a roof replacement can run anywhere from $12,000-$70,000 to be fully replaced, without warranty this can be a major financial hurdle. By taking preventative measures that may require an upfront investment, they can ultimately pay off in the form of a healthier, longer-lasting roof.

Proactive minus Pressure Washing

While pressure washing might seem like a quick and easy solution for removing moss from your roof, it comes with a host of risks and drawbacks. From voiding your warranty to failing to address the root cause of moss growth, pressure washing can ultimately cost you more time and money in the long run. By being proactive and prioritizing the long-term health of your roof, you can ensure that it remains strong, durable, and moss-free for years to come.
