For new and existing roofs, we independently assess technical decisions on behalf of the client against the design, site evidence, system performance and whole-life requirements.
The right time to intervene
When should a roof consultant become involved?
The greatest value is achieved before materials are ordered and site work begins. Systems and details are reviewed during design; specifications and tender scopes before procurement; and critical work before it is concealed during construction. On existing buildings, a consultant should be appointed before the first repair decision so that the root cause can be established.
Prevent risk through design
Compare scope at tender stage
Verify before work is concealed
Service scope
Independent technical review and assurance from the first decision to handover.
We tailor roof condition assessment, technical surveying and reporting, system selection, construction detailing, specification writing, tender review and site inspection to the project’s requirements.
01
Roof Condition Assessment and Risk Analysis
Review of drawings for performance, buildability and continuity of detailing.
Detailed scope
We co-ordinate the architectural, structural and building-services information to check falls, drainage capacity, condensation risk, ventilation, supporting construction and continuity of detailing. Findings are graded by significance, and items requiring revision are reported with drawings and written commentary.
02
System and Material Selection
Comparison of alternatives against service life, maintenance, budget and project conditions.
Detailed scope
We do not select materials on initial cost alone. Climate, roof pitch, building geometry, use, access for maintenance, expected service life and architectural appearance are assessed, and viable alternatives are presented with their benefits and risks.
03
Construction Detailing and Technical Solutions
Solutions for junctions, drainage, ventilation, fixing and thermal movement.
Detailed scope
We develop construction details for ridges, eaves, valleys, parapets, chimneys, rooflights, abutments and interfaces between dissimilar materials. Fixed and sliding clip zones, movement allowances and uninterrupted drainage paths are defined on the drawings.
04
Technical Specifications, Tendering and Tender Evaluation
Comparison of specifications, bills of quantities and tender scopes.
Detailed scope
We compare tender submissions not only by total price, but also by product description, sheet thickness, quantity, accessories, substrate, workmanship, scaffolding and access, delivery, warranties and exclusions. Missing or non-comparable items are identified so that the client can make an informed decision.
05
Site Inspection and Quality Assurance
Reporting on site workmanship against the design and technical requirements.
Detailed scope
We inspect critical stages on site, from the supporting substrate to the completed covering. Non-conformances are recorded with photographs, locations and technical reasons; remedial recommendations and close-out inspections are reported. This allows defects to be addressed before they are concealed.
06
Project-Specific Technical Mock-ups
Full-scale fabrication and verification of critical roofing and façade details before site installation.
Detailed scope
Where standard drawings are insufficient, we can produce project-specific technical mock-ups for chimneys, eaves, ridges, ventilation details, façade junctions and interfaces between different materials. Geometry, layer sequence, mechanical joints, drainage, ventilation and fabrication methods are assessed at full scale; the approved solution then becomes the benchmark for site installation and quality control.
Decision and deliverables framework
What is made clear at the end of the appointment?
The same document package is not applied to every project. Deliverables are defined at the outset according to the building condition, project stage, access constraints and scope of appointment.
Deliverables according to the scope
Photographic technical survey and findings record
Risk, priority and technical recommendations schedule
Detail, specification or tender-scope documentation
Site inspection and close-out records
The final list of deliverables is confirmed in writing, together with the scope and limits of responsibility, before the fee proposal is issued.
Basis of technical assessment
Approved architectural, structural and building-services information
Site measurements, photographs and controlled opening-up findings
Current manufacturer documentation and system details
Applicable TS/EN standards and mandatory statutory requirements
Applicable references are identified within the appointment after the system, building type and project location have been confirmed.
Service boundaries and independence
The same technical knowledge; three distinct services and three distinct responsibilities.
Consultancy, product supply and selected installation projects are delivered under separate scopes and responsibilities; no service is conditional on another.
01 · Independent consultancy
Technical advice and assurance
Design information, specifications, quantities, tender submissions and site findings are reported independently of any supply or installation contract.
02 · Material supply
Supply to the approved system
Sheets, coils and accessories are supplied against the approved quantity take-off and delivery schedule.
03 · Selected installation projects
A separate scope for suitable projects
Installation is contracted separately and only where the technical details, programme and site conditions are suitable.
Independence principle: Where we are also the supplier of a material or installer of the work, that role is disclosed clearly to the project team. Alternative systems are compared on technical and commercial grounds; report findings are never altered to favour a commercial preference.
Site-led assessment
Measured and recorded on site—not assumed at a desk.
Water paths, falls, valleys, chimneys, parapets and accessible build-up layers are measured and recorded on site.
Site measurement and inspectionRecord of falls, dimensions, drainage routes and existing condition.
Critical junction detailInspection of chimneys, valleys, eaves, ridges, parapets and rooflights.
Installation stageVerification of workmanship and remedial work before concealment.
Completed building and reportPhotographic records, finding classification, recommendations and deliverables.
Full-scale verification where required
We verify critical junctions with mock-ups before installation begins on site.
Not every detail requires a full-scale mock-up. At critical chimneys, eaves, ridges, valleys, vents, façade junctions, openings and interfaces between different materials, however, we establish how the drawing will be built and produce a full-scale mock-up where appropriate. This allows the geometry, build-up sequence, mechanical joints, drainage, ventilation and workmanship method to be verified together before installation starts.
An approved mock-up is more than a sample: it is the site team’s installation reference and the agreed quality-control benchmark.

Technical reporting methodology
The working standard is transparent, not the confidential report itself.
A technical survey is not undertaken merely to list defects. Existing condition, risk priority, intervention areas, remedial strategy and installation hold points are assessed together to provide the technical basis for the client’s repair, refurbishment or investment decision.
Why should roof consultancy begin before installation?
Many cases of water ingress, condensation, corrosion and covering failure begin when falls, drainage, ventilation, fixing and thermal-movement provisions are not defined in the design.
Independent design review and technical risk analysis
Before a product or installer is selected, we review the roof design as a complete system and establish a buildable solution, clear responsibility boundaries and an inspection method.
Photographic surveys, site inspection and technical reporting
Falls and water paths, concealed gutters, junctions, build-up layers and previous repairs are examined together; findings are reported with photographs, measurements and recommended solutions.
Define your roofing and façade decisions at design stage.
Confidentiality principleClient reports are not published publicly because they contain project and building information. Only the reporting standard used by Butik Roof & Project Consultancy and anonymised technical examples are shown here.

Survey Method
Documents first, then the site, followed by technical assessment.
Design and repair records are reviewed; geometry, falls, water paths, valleys and gutters, junctions and accessible build-up layers are recorded by measurement and photography.
Findings and Risk Grading
HighActive water ingress, a risk to life or property, or rapid deterioration. Urgent action is required.
MediumA non-conformance that is not yet causing active damage but reduces service life and system performance.
LowA finding relating to maintenance, workmanship or monitoring that can be managed through planned remedial work.
Illustrated Defect Example
Failure to direct water mechanically at a critical junction
Primary weathering around chimneys, parapets, valleys and rooflights must be achieved by continuous folded metalwork configured to the direction of water flow and completed with an appropriate counter-detail—not by exposed fixings or surface-applied sealant. Sealant may be used only at supplementary locations approved by the manufacturer; exposed screws and open penetrations must not remain in the outer covering.
Example Technical Recommendation
Open up the defective junction and inspect the underside, separation layer and supporting substrate. The replacement detail must allow for capillary rise and backed-up water; metal components are mechanically folded with adequate laps and cover. Fixed and sliding clips, tray lengths and the direction of thermal movement are reconfigured in accordance with the manufacturer’s details.
