Start with the same description of the job
Two prices are only comparable when they cover the same work. One quotation might include moss removal, a suitable treatment and clearance of debris generated by the work. Another might cover only a treatment application. A lower headline figure does not tell you which approach is appropriate for your roof.
Send each contractor the same postcode, property type and description of your concern. Explain whether you want an appearance improvement, have moss falling into gutters, or have noticed a possible defect. Photographs taken safely from ground level can help the initial conversation, but they may not establish the roof material or condition.
Ask for the scope in writing
Use these questions when a quotation arrives:
- Which roof slopes, extensions and outbuildings are included?
- What material and condition has the quotation assumed?
- What method is proposed, and why is it suitable?
- What access equipment is included in the price?
- Is any treatment included, and what result should I expect?
- How will nearby surfaces, planting and drainage be protected?
- Does clean-up include gutters and debris from this work?
- Are repairs, existing drainage faults or other items excluded?
Separate cleaning from repairs
If a tile is cracked or a flashing is defective, cleaning will not put it right. Ask how suspected defects will be recorded and whether the job should wait for a roofer. An estimate that depends on repairs or further inspection should say so clearly.
Be cautious about promises that cleaning will make an old roof new, stop every future leak or permanently prevent moss. Ask what a guarantee actually covers, its duration and any maintenance conditions. Keep the written quotation and agreed changes together.
Make the next step easy
Before accepting, confirm the payment terms, weather arrangements and who to contact if the scope changes. Ask whether any tax is included where applicable. A clear explanation is more useful than a precise-looking price based on assumptions.
