Have you ever looked up at your roof and seen it dirty? You may be thinking about using a pressure washer to clean it quickly. But the question is, Can you pressure wash an asphalt roof?
No, you shouldn’t pressure wash an asphalt roof. The strong spray can harm the roof by knocking off important protective bits. This can make your roof wear out faster and lead to leaks. It’s better to clean your roof gently so it won’t damage it.
We’ll share the smart way to clean your roof without hurting it. So, before you grab that pressure washer, let’s dive into what you need to know.
KEY Takeaways
- Pressure Washing Risks: Avoid using a pressure washer on asphalt roofs to prevent stripping protective granules and causing leaks.
- Opt for Soft Washing: Gentle cleaning methods, like soft washing with specialized solutions, protect your roof’s integrity and extend its life.
- Seek Professional Advice: Consult a roofing expert to safely clean your asphalt roof without damaging it, ensuring its durability and appearance.
Pressure Washing Risks: Not Worth The Risk
Even though it seems like a quick way to clean, pressure washing your asphalt roof can cause much harm.
Not Recommended
The National Roofing Contractors Association (NRCA) and asphalt shingle manufacturers strongly advise against pressure washing your asphalt roof. This consensus stems from the inherent risks associated with the high water pressure and its impact on the delicate structure of asphalt shingles.
Potential Shingle Damage
Pressure washing can inflict severe damage on your asphalt shingles in several ways:
- Granule Loss: Protective granules embedded in asphalt shingles shield them from UV rays and weather elements. The force of a pressure washer can dislodge these granules. This exposes the asphalt to early cracking.
- Shingle Dislodging: The strong stream of water can dislodge or lift shingles. This creates gaps in your roof’s barrier. This exposes your roof deck and structure to water. It leads to leaks, mold, and costly repairs.
- Underlayment Damage: Even when the shingles remain intact, the washer can damage the underlayment. This is the waterproof layer beneath the shingles. This can lead to leaks and water damage even if the shingles appear unharmed.
Asphalt Roof Sensitivity
Asphalt shingles are inherently sensitive to high pressure and impact. They are designed to be flexible and weatherproof, not withstand the powerful blast of a pressure washer. The damage can be quick and clear. Or it can develop slowly. This leads to early roof failure and high costs.
Gentle Cleaning Alternatives
Instead of using a strong pressure washer, you can try these kinder cleaning methods:
Soft Brushing
Using a soft brush is a great way to clean your roof. You can gently scrub away dirt, moss, and other stuff that shouldn’t be on your roof.
This method is very safe and doesn’t harm your roof’s shingles. Just make sure you use a soft brush and do it carefully to avoid any damage.
Low-Pressure Hose
A garden hose with a low-pressure nozzle can also help clean your roof. This way, you can rinse off the roof without being too harsh. It’s like giving your roof a gentle shower.
This method helps remove loose dirt and grime without risking the protective parts of your shingles.
Delicate Material Considerations
Asphalt roofs are made of materials that can get damaged easily. That’s why it’s important to be gentle when you clean them. Avoid harsh chemicals or cleaners that strip the roof’s protective layer away.
Also, remember to walk carefully on your roof to avoid breaking the shingles. Always choose products and methods that are safe for your type of roof.
