Normative Basis
This document does not replace EVS 920-5, legislation, the project, calculations, or the manufacturer’s instructions.
RFP-002 describes the internal House of RAMERK procedure for preparing, controlling, documenting, and handing over roofing works. Applicable requirements are confirmed separately for each project.
Industry standards remain the property of their authors and rights holders. This book explains only the RAMERK working process.
EVS 920-5 · Roofing Standard
Purpose
A roof is complete not when it merely looks finished, but when its layers, water paths, junctions, and documentation form one verified system.
The purpose of RFP-002 is to make roofing quality control consistent, clear, and demonstrable from substrate inspection through handover to the owner.
Scope
The procedure applies to roof repairs and roof construction within the agreed project scope.
Responsibilities
Every inspection point has an owner.
Project
Defines the construction, materials, falls, and junctions.
Site Team
Executes the work in accordance with the project and method statements.
Quality Control
Inspects layers before they are concealed and records the evidence.
Handover
Compiles the roof passport, records, and owner recommendations.
Before Work Begins
Most roofing defects begin before the first layer is installed.
Material Verification
A material must be correct not only by name, but also by its intended function within the system.
| Check | Evidence | Decision |
|---|---|---|
| Brand and type | Marking, DoP, specification | Match project |
| Compatibility | Manufacturer’s system | Confirmed |
| Condition | Inspection of packaging and material | No damage |
| Storage | Photographs and log | Protected |
Substrate & Slopes
Water must have a predesigned path.
Before concealment, the substrate, falls, local depressions, outlet levels, and the ability to drain water continuously are checked. Any nonconformity is corrected before subsequent layers are installed.
Numerical falls and tolerances are taken from the project, applicable standard, and manufacturer’s system.
Waterproofing
Waterproofing is accepted as a continuous envelope.
Drainage
The roof must drain water in the designed direction without unintended traps.
Outlets and gutters are unobstructed and accessible to water.
An overflow is provided where required by the project.
Guards, clamps, and heating are installed as specified.
Testing with water or another agreed method.
Flashings & Connections
Roof reliability is most often determined where the geometry changes.
Hidden Works
Every layer that is concealed must leave evidence behind.
Before concealment, records and photographs are prepared for the vapour control layer, insulation, fixings, falls, waterproofing, outlets, and junctions. Photographs must show not only the general view, but also scale, location, and area identification.
Inspection & Testing
The inspection method is selected according to the risk and roof-system type.
Visual
Continuity, damage, geometry, and junctions.
Dimensional
Levels, falls, and element positions.
Integrity
Agreed testing of joints or the membrane.
Drainage
Verification of an unobstructed water path.
Defect Record
A roofing defect is described in terms of risk, not appearance alone.
| Class | Meaning | Action |
|---|---|---|
| Critical | Risk of water ingress or loss of safety. | Stop / repair |
| Major | Noncompliance affecting the design or durability. | Correct before handover |
| Minor | A local deviation without immediate risk. | Record and agree |
Handover
The handover includes not only the roof, but also the knowledge required to manage it.
House Promise
RFP-002 turns roofing works into a transparent process: designed, controlled, and preserved in documentation.
