Real Example: Lewisham Garage Roof Removal
Property: Semi-detached house, Lewisham. Asbestos cement garage roof (120 sq ft), corrugated sheets. Homeowner discovered asbestos during renovation planning.
Timeline: Survey (1 day) → Quote approval (2 days) → Removal & replacement (4 days) → Air testing (2 days) = 9 days total.
Key Insight: This homeowner initially resisted the £1,200 base repair, thinking "just remove the roof." Once we showed her photos of water damage and explained the subsidence risk, she agreed. Without the repair, she'd have faced £5,000+ in structural damage within 2–3 years. This is why 85% of our customers approve the full removal + replacement package once they understand the risks.

Larger properties cost more. A 100 sq ft garage roof costs £3,500–£4,500. A 200 sq ft roof costs £5,500–£7,000.
Material Type
Asbestos cement (most common) costs £1,200–£2,200 to remove. Asbestos insulation costs more due to complexity.

Structural Damage

Hidden Costs to Avoid
Structural Repairs
80% of Lewisham garage roofs need base repair (£800–£1,400). Always get a structural assessment before removal.
Air Testing
Mandatory post-removal testing costs £300–£600. This is NOT optional—it's a legal requirement under CAR 2012.
Waste Disposal
Licensed facility disposal costs £200–£500. Cheap quotes often exclude this or use unlicensed facilities (illegal).
Contingency (10–15%)
Unexpected structural damage or asbestos in unexpected locations can add 10–15% to the quote. Budget for this.
Replacement Materials
New roofing, guttering, or downpipes add £1,500–£3,500. Some quotes exclude this, leaving you with an exposed structure.
VAT & Compliance
All quotes include 20% VAT. Ensure the quote is itemised and includes all compliance documentation.
Ways to Reduce Your Cost
Encapsulation vs. Removal
Encapsulation (sealing asbestos in place) costs 30–50% less than removal but requires ongoing maintenance. Only suitable for intact, non-friable asbestos. Removal is safer long-term.
Phased Removal
If you have multiple asbestos items (roof + flue + guttering), removing them together costs 15–20% less than separate jobs. Negotiate a package deal.
Planned vs. Emergency
Emergency removal (24/7 response) costs 20–40% more. If possible, schedule removal during normal business hours to save money.
Material Choices
GRP roofing costs £1,000–£1,500 less than metal roofing but has a shorter lifespan. Choose based on your budget and long-term plans.
Bulk Discounts
If you're a property developer or landlord with multiple properties, negotiate bulk pricing. We offer 10–15% discounts for 3+ jobs.
Frequently Asked Questions
Why is my quote higher than expected?
Common reasons: structural damage (80% of Lewisham jobs need base repair), complex geometry, difficult access, or additional asbestos found during removal. Always budget 10–15% contingency.
Can I negotiate the price?
We offer competitive, transparent pricing. Bulk discounts available for 3+ jobs. Emergency removal costs more due to 24/7 availability. We don't negotiate on safety or compliance.
Do you offer payment plans?
Yes. For quotes over £3,000, we offer 50% upfront, 50% on completion. Contact us to discuss financing options.
What's included in the survey cost?
Survey cost (£150–£400) includes property inspection, material sampling, lab testing, and a detailed report. This is deducted from your removal quote if you proceed.
Is air testing mandatory?
Yes. Air testing (£300–£600) is a legal requirement under CAR 2012. It proves the air is safe post-removal. This is NOT optional.
What if I can't afford the full removal?
Encapsulation (sealing) costs 30–50% less but requires ongoing maintenance. Phased removal spreads costs over time. Discuss options with us.
Are there any hidden charges after removal?
No. Our quotes are itemised and include all labour, materials, waste disposal, air testing, and compliance documentation. No surprises.
