We’re a Home Improvement Agency — these prices are estimates only and may vary by supplier.
Our customers typically pay around 30% less than going direct, thanks to our quote-matching and negotiation system, and our checks on product and installer standards.
Quick note: Lower-end guide prices typically reflect a straightforward, compliant roofline replacement using standard uPVC systems (fascias/soffits/guttering) from local installers. Higher-end prices for the same measurements are usually driven by higher-spec products and materials (e.g. premium uPVC profiles, aluminium systems, thicker gauge guttering, upgraded ventilation details), stronger warranties, and sometimes BBA-approved systems/specifications where applicable. Pricing can also sit higher when a national firm is supplying/fittting compared with a good local specialist, even with similar access and scope. If your job needs scaffolding, add it as a separate line item in the calculator, as access and height can change the final cost significantly.

Roof Trim Cost Calculator – FAQs
What’s included in the estimate?
Your range is a guide for supply + installation incl. VAT based on the items you add (e.g. fascias, soffits, bargeboards, guttering, downpipes, cladding, eaves protection). It also factors a postcode-based regional adjustment.
It assumes a typical replacement scope (remove old where required, fit new, standard fixings and trims). Exact details can vary after an installer survey.
Do I need scaffolding, and how do I add it?
Many first-floor roofline jobs can be done from ladders or a tower, but scaffolding is common for taller homes, tricky access, larger overhangs, or where installers need a safer working platform.
Scaffolding is added as its own line item in the calculator (scroll to the scaffolding option and add it like any other item). Costs vary a lot by height, length, access and hire duration, so it’s kept separate.
How do I measure for fascias and soffits (especially deep porches)?
Use your total roofline length (metres) for fascias and guttering. For soffits, select the closest projection depth (the distance from the wall out to the fascia).
If you have a deep porch overhang (e.g. 600–1200mm), choose the larger soffit projection so the estimate reflects the extra material and fitting time.
Why do roofline quotes vary so much for the same measurements?
Price differences usually come from product grade and specification (standard uPVC vs premium profiles, aluminium options, thicker gauge guttering, ventilation details), workmanship/warranty level, and the installer’s overheads.
National firms often price higher than strong local specialists. Access (height, conservatories below, extensions, tight driveways) and whether scaffolding is needed can also shift the final price.
What should I compare to make sure quotes are like-for-like?
Ask each installer to confirm:
- Exact scope: remove/dispose old roofline, any timber repairs, ventilation/over-fascia vents.
- Product spec: material (uPVC/aluminium), profile thickness, colour finish, gutter size and style.
- Access: ladders/tower/scaffolding included, and for how long.
- Guarantee length and what’s covered (materials, workmanship, leaks, sagging).
- Payment terms and whether any extras are excluded (skip hire, repairs, painting, etc.).
