In many refurbishment projects, yes but only if the existing roof build-up is suitable.

Before applying a new waterproofing system, the existing surface should be checked for adhesion, stability, moisture, contamination, cracks and compatibility with the proposed Triflex system.

If the existing waterproofing is securely bonded and technically suitable, overlaying it can reduce unnecessary removal, waste and disruption. If the existing layer is loose, damaged or moisture is trapped underneath, additional preparation or removal may be required.

This is why Triflex recommends assessing the existing roof before deciding whether to repair, overlay or replace.

Yes. Triflex offers liquid-applied systems for both metal roof refurbishment and the critical details that commonly cause leaks.

Metal roofs experience thermal movement, UV exposure, heavy rainfall, corrosion and movement around seams, fasteners, gutters and penetrations.

Depending on the roof condition, Triflex Metal Coat can be used to refurbish and protect metal roof surfaces, while Triflex ProDetail can waterproof vulnerable details such as seams, joints, gutters, penetrations, roof edges and transitions between different materials.

The correct system should be selected after reviewing the metal condition, corrosion, previous coatings and leak locations.

Yes. These complex roof details are one of the key applications for Triflex liquid-applied waterproofing systems.

Leaks often begin around gutters, skylights, pipes, vents, upstands, seams and other areas where different materials meet or movement occurs.

Because Triflex ProDetail is applied in liquid form and reinforced with fleece, it can follow irregular shapes and create a seamless waterproofing layer around difficult details without relying on prefabricated sheet shapes or multiple overlapping joints.

For projects involving glass, metal, concrete or other different substrates, the appropriate preparation and primer should be confirmed before application.

The purpose of the inspection is to understand why the roof is failing before recommending a waterproofing system.

Depending on the project, the Triflex Malaysia technical team may review:

• the existing roof and waterproofing condition

• recurring leak locations

• substrate condition

• existing coatings or membranes

• gutters and drainage

• seams, joints and penetrations

• skylights and roof interfaces

• visible cracks or movement

• moisture-related issues

• previous repairs

Following the assessment, Triflex can provide technical findings and guidance on the most appropriate repair, refurbishment or waterproofing approach.

The objective is to give the project team a clearer basis for deciding what should be repaired, retained, overlaid or replaced.

Triflex systems are installed by contractors trained in the correct processing and application methods.

Triflex authorized applicators undergo product application training covering areas such as substrate preparation, primers, mixing, fleece reinforcement, system build-up and detail application.

Triflex also provides ongoing training courses and seminars to help applicators keep their technical knowledge and practical skills up to date.

For building owners and project teams, this is important because long-term waterproofing performance depends not only on the product specified, but also on correct preparation and application on site.

Service life and warranty are not the same thing.

A service-life assessment describes how long a waterproofing system is expected to remain functional under defined conditions when it is correctly designed, installed, used and maintained.

A warranty is a contractual or legally defined commitment covering a specific project and period.

Selected Triflex systems have demonstrated performance in real buildings for more than 25 years, and extended testing has confirmed an expected service life of up to 40 years for selected systems.

The warranty available for an individual project depends on factors such as the Triflex system specified, project design, application and agreed project conditions.

For this reason, project teams should not interpret a 25- or 40-year expected service life as an automatic 25- or 40-year warranty.
