Roof covering is the outer covering layer or set of components finishing the roof, such as tiles or a membrane. Its name does not establish the complete roof assembly or explain how the junctions have been formed.
In a quotation, roof covering may refer either to the material or to a broader work item. Ask whether substrate preparation, removal, fixing and perimeter details are included. Without clarification, two similar-sounding proposals may describe substantially different instructions.
Visible damage to the covering does not automatically establish the condition of underlying layers. Record the observation and have the relationships assessed. Material selection should follow the actual roof rather than colour alone or a general preference for one product.
Worth asking
Frequently asked questions
Does new covering always include new insulation?
No. That needs to be identified separately within the scope.
Is a material name enough for comparison?
No. Scope, layers and junctions make the proposal meaningfully comparable.
