How Can Pressure Washing Damage Your Roof?
Pressure washing your roof might seem like an efficient way to clean it, but it can lead to significant damage. Here are the key reasons why you should avoid using a pressure washer on your roof:
Damage To Roof Material
Pressure washing can cause considerable damage to various roofing materials. For asphalt shingles, the high-pressure water blasts away the protective granules that shield the shingles from the elements, thus reducing their lifespan and necessitating expensive replacements sooner than expected.
Similarly, ceramic, cement, or slate tiles are susceptible to cracking or breaking under the force of the water. The pressure can also dislodge these tiles, leading to additional damage and potential leaks. Furthermore, the powerful jets of water can break down the adhesive bonds between the roofing materials, compromising the roof's structural integrity and creating pathways for leaks.
Risk Of Leaks
The risk of leaks is another significant concern when pressure washing a roof. High-pressure water can penetrate small cracks and gaps, allowing water to seep into the roof space. This infiltration can cause substantial water damage to the roof's underlayment and the interior of the home. Additionally, the seals around roof features like skylights and vents, which are designed to keep water out, can be damaged by pressure washing. This damage can result in leaks and further exacerbate water intrusion issues.
Structural And Electrical Hazards
Using a pressure washer on your roof can also pose structural and electrical hazards. The pressure can damage not only the roofing material but also the underlying structure, leading to costly repairs and even potential structural failure if not addressed promptly. There is also a significant risk of electrical hazards. If water from the pressure washer infiltrates electrical panels or exterior outlets, it can cause electrocution or severe electrical damage, posing a serious safety risk to anyone near the area.
Safety Concerns
Safety concerns are paramount when considering pressure washing your roof. A wet roof becomes extremely slippery, significantly increasing the risk of falls and serious injuries. Climbing onto a wet roof while handling a pressure washer further adds to the danger, making the task hazardous. Additionally, manoeuvring a pressure washer on a roof is inherently difficult and hazardous. The risk of tripping over hoses or mishandling the equipment can lead to accidents and injuries.
Warranty Issues
Many roofing warranties explicitly state that using high-pressure washing methods will void the warranty. This means any damage resulting from pressure washing will not be covered, leaving you financially responsible for all repairs. Protecting the warranty on your roof is crucial to ensuring long-term coverage against potential future failures and damages.
Ineffective Cleaning
Pressure washing might not only damage your roof but also prove ineffective at cleaning it. Instead of removing moss and algae, pressure washing can spread these organisms to other areas of the roof, making the problem worse. Additionally, if the pressure used is too low, the washing may not effectively clean the roof, leaving behind a slippery mess without addressing the underlying causes of dirt and growth.
Alternatives To Pressure Washing
Instead of pressure washing, consider safer and more effective alternatives like soft washing. A professional soft wash uses low-pressure water combined with cleaning solutions to safely remove dirt, algae, and moss without damaging the roof. Manual cleaning methods, such as using scraping tools and gentle cleaning techniques, can also effectively clean the roof without the risks associated with high-pressure water.
