Roof Waterproofing Quotation Malta: 10 Questions to Ask

Waterproofing quotes can look similar while covering very different preparation, detailing and warranties. Compare the written systems, not only the final price.

Scope and substrate

Ask what surface is being treated, its measured area, existing finishes, falls to outlets and suspected moisture beneath any old system. Does the quote include surface cleaning, preparation, repairs, crack treatment and primers? Will loose or failed old layers be removed where appropriate?

Materials and workmanship

Request the named manufacturer, product type, preparation standard, primer, reinforcement where specified, coating thickness or consumption, number of coats and curing conditions. Manufacturer data sheets take priority over an arbitrary 'two coats' promise. Clarify who supplies materials, equipment and safe access.

Details and exclusions

Ask specifically about upstands, joints, edges, door thresholds, outlets, pipe penetrations, movement joints and adjacent walls. Is rainwater drainage improvement part of the scope? How will the installer avoid trapping moisture or coating incompatible surfaces? Are scaffolding, waste and making-good included?

Testing and aftercare

Agree inspection photos during application, suitable completion checks, the warranty provider and the conditions that can void it. A quote should state what happens if concealed substrate damage appears. Plan seasonal roof-drain inspections even after a new membrane is installed.
