Our Process Pressure washing a roof can be a bad idea for several reasons: Damage to Roofing Materials
High-pressure water can damage, dislodge, or remove roofing materials such as shingles, tiles, or metal roofing components. This damage can lead to leaks, decrease the roof's lifespan, and necessitate costly repairs or replacements. Water Damage
The high pressure can force water underneath the roofing materials and into the roof deck or attic space, leading to water damage, mold growth, and structural issues. Warranty Voiding
Many roofing material manufacturers specify the acceptable cleaning methods for their products. Pressure washing voids warranties as it is not an approved cleaning method, leaving the homeowner to cover the cost of any resulting damages. Safety Risks
Using a pressure washer on a roof poses significant safety risks. The force of the water can lead to a loss of balance, and working on a wet, slippery roof increases the risk of falls, which can result in serious injuries. Improper Cleaning
Pressure washing may not effectively remove all types of roof dirt, algae, moss, or fungal growths. Some organisms can have roots or structures that hold tightly to the roofing material, and while pressure washing might remove the surface layer, it might not eliminate the organism, allowing it to quickly regrow. |
