Roof Services Comparison FAQs
Any questions?
Can I combine services?
Yes, some clients choose roof washing for immediate results followed by treatments for long-term protection. We can recommend the best combination for your specific situation and budget.
Which service is best value?
Roof treatments typically offer the best long-term value with lower cost and longer protection. However, if you need immediate results, washing is necessary. We’ll provide honest recommendations based on your needs, not just the most expensive option.
How do I know what my roof needs?
We provide free assessments and honest recommendations. We’ll evaluate your roof’s condition, discuss your goals and timeline, and recommend the most appropriate service. We’ll never recommend services you don’t need.
Do all services work on all roof types?
Yes, all three services are suitable for concrete tiles, metal roofing, and terracotta. We adjust our techniques based on your specific roof material.
Are the products safe for rainwater collection?
Roof treatments are completely safe for rainwater collection systems. For roof washing and pre-paint washing, we recommend disconnecting tanks during the process and for the first rain afterwards, then reconnecting once the system is clear.
How often should I have my roof serviced?
This depends on your chosen service and your roof’s exposure. Roof washing typically lasts 12-18 months. Roof treatments last 12-24 months. We recommend scheduling before growth becomes heavy—preventative maintenance is more effective and cost-efficient than addressing severe growth.
