Common questions about costs and estimates for this service.
For steeply pitched roofs, contractors should factor in increased labor time due to safety protocols, specialized equipment (like roof anchors and harnesses), and the extra care required to prevent slippage or damage. Consider adding a percentage surcharge (e.g., 15-30%) on top of the standard per-square-foot rate to cover these additional complexities and risks.
Heavy algae, lichen, or moss growth typically requires stronger, specialized cleaning solutions and more dwell time, often necessitating a second application or more intensive scrubbing. Include the higher cost of these chemicals and additional labor hours in your Mid-range or Premium tier pricing, or as a separate line item for significant infestations.
Yes, different materials demand different approaches. Asphalt shingles often require soft washing to prevent damage, while metal roofs might withstand higher pressure. Tiled roofs could be more fragile. Factor in the specific cleaning solutions and techniques needed for each material, which may influence your material costs and labor time, especially if specialized training or equipment is required.
Recommend a Premium service for larger roofs, those with a very steep pitch, severe and stubborn biological growth (like extensive black streaks or lichen), or if the client requests the most thorough cleaning with protective treatments. It's also suitable for neglected roofs that haven't been cleaned in a long time and require extensive restorative work.
Clearly outline in your contract what is covered and what might incur additional charges (e.g., unexpected repairs discovered during cleaning, extensive gutter blockage). It's best practice to communicate any unforeseen issues and their associated costs with the homeowner immediately upon discovery, before proceeding with the extra work, and get their approval.
