Professional Roofing Estimating Services Across the UK
We prepare roofing cost estimates for contractors, builders and developers across the UK, covering materials, labour and installation. Each estimate is built from detailed quantity take-offs, so you can plan the job, set a budget and tender with confidence.
From a single roof replacement to a large development, you get a clear, line-by-line estimate that shows quantities, materials and labour.
What a Roofing Estimate Includes
Each estimate is built from your drawings and specification, and covers:
- Quantity take-offs: roof areas, pitches, ridges, hips, valleys and verges, measured from your drawings.
- Material schedules: tiles, slates, membranes, battens, insulation and fixings, each listed and priced.
- Labour calculations: labour shown for each part of the roof, from strip-out to finish.
- Cost breakdown: totals for materials, labour and the overall estimate.
- Assumptions: inclusions, exclusions and assumptions written down, so the scope is clear.
Roof Estimating Services for UK Contractors
Our roof estimating services save roofing contractors hours of measuring and pricing. You receive measured quantities and a priced breakdown that you can check, adjust to your own rates and use in your tender.
- Spend less time on take-offs and more time on site.
- Price more tenders without adding to your workload.
- Reduce the risk of missed areas, fixings or details.
What We Need to Start
- Roof plans, elevations and sections, in PDF or CAD format
- The roofing specification, including the type of covering
- Details of insulation, membranes and ventilation
- Information on any strip-out or repairs to the existing roof
- Your programme or tender deadline
Pitched and Flat Roof Estimating
We estimate both pitched and flat roofs, using the same line-by-line method:
- Pitched roofs: tiles, slates, battens, underlay, ridge and hip tiles, valleys and lead flashings.
- Flat roofs: single-ply membranes, built-up felt, liquid systems and GRP, with insulation and upstands.
- Roof timbers: rafters, joists, wall plates and decking, where they are part of the scope.
- Rainwater and roofline: gutters, downpipes, fascias and soffits.
Roofing Estimating for Different Types of Project
- New builds: full roof coverings, timbers and roofline for each plot.
- Roof replacements: strip-out, disposal and new coverings.
- Extensions and loft conversions: new roof areas, dormers and tie-ins to the existing roof.
- Refurbishments: repairs, re-covering and upgrades to insulation.
- Commercial and industrial buildings: large flat roofs, membranes and cladding where specified.
How We Build a Roofing Estimate
Each estimate follows the same steps, so you can follow the logic and check it against your drawings:
- Review the drawings and specification, and note any gaps.
- Measure the roof areas, allowing for the pitch of each slope.
- Measure ridges, hips, valleys, verges and eaves in metres.
- Price materials and labour for each part of the roof.
- Write down the inclusions, exclusions and assumptions, then issue the estimate.
Roofing Items We Price Line by Line
Where they appear on the drawings or specification, we price each of these separately:
- Tiles, slates and roof coverings
- Underlay, membranes and battens
- Ridge, hip and valley details
- Lead work and flashings
- Insulation and vapour control layers
- Roof timbers and decking
- Gutters, downpipes, fascias and soffits
- Rooflights and roof ventilation
- Strip-out and disposal of the existing roof
Why Line-by-Line Pricing Helps Your Tender
A single lump sum makes it hard to see what is included. A line-by-line estimate gives you a clearer basis for tender:
- You can see exactly which areas and details are included.
- You can check the assumptions before you commit to a price.
- You can compare options, such as tiles against slates, and see the effect on cost.
- You can explain your price clearly to your client.
Roofing Terms Explained
These terms come up in most roofing estimates:
- Pitch: the angle of a roof slope, which affects the true roof area.
- Ridge: the top line where two roof slopes meet.
- Hip: the sloping line where two roof slopes meet at an outside corner.
- Valley: the line where two roof slopes meet at an inside corner.
- Verge: the edge of a roof at the gable end.
- Eaves: the lower edge of a roof, where it overhangs the wall.
- Flashing: a strip, often lead, that seals joints between the roof and walls or chimneys.
- Take-off: measuring quantities from the drawings.
What You Receive With Your Roofing Estimate
Your estimate is set out so that you can check it and use it for tender. It normally includes:
- A short scope summary, listing the drawings and specification used
- Measured roof areas and linear details
- Material schedules for each part of the roof
- Line-by-line pricing, with labour shown separately
- A list of inclusions, exclusions and assumptions
Frequently Asked Questions About Roofing Estimating
What is included in a roofing estimate?
Each estimate includes quantity take-offs, material schedules, labour calculations and a cost breakdown. All of it is based on your drawings and specification.
What types of roofing projects do you cover?
We cover pitched and flat roofs, roof replacements, loft conversions, residential and commercial buildings, refurbishments and new builds.
How long does it take to complete an estimate?
Turnaround is usually one to three working days. The exact time depends on how large and complex the project is.
Do you estimate flat roofs as well as pitched roofs?
Yes. We price both, including single-ply, felt, liquid and GRP flat roof systems, as well as tiled and slate pitched roofs.
Do you allow for the roof pitch when measuring?
Yes. Roof areas are measured on the slope, not just on plan, so the quantities reflect the true area to be covered.
Do you provide a free sample estimate?
Yes. A free sample estimate is available, so you can see our format before you decide.
Can I use my own labour rates?
Yes. Quantities and labour are shown separately, so you can apply your own rates if you prefer.
