Your roof is constantly exposed to rain, moisture, UV, heat and changing weather conditions. Over time, porous roof tiles can absorb water and become vulnerable to staining, moss, algae, lichen and general weathering. 

The right roof sealer can help protect suitable roofing materials and extend their service life.

A penetrating roof sealer can help reduce the amount of water absorbed into porous roofing materials, helping protect the substrate from moisture-related deterioration while allowing it to remain breathable.

ImperGuard is a professional-grade water repellent suitable for porous materials including terracotta and porous roof tiles. It penetrates the surface to provide invisible, breathable protection against water, moisture, erosion and biological growth.

Australian roofs are exposed to intense sun, rain and temperature fluctuations. Applying a suitable roof sealer can help reduce the effects of weathering and help maintain the condition and appearance of suitable roof surfaces.

For roofs requiring broader protection, ImperGuard Ultra 4 in 1 provides water repellency, stain resistance, antimicrobial protection and remineralisation in one penetrating treatment. It is suitable for porous materials including concrete, terracotta and slate.

Moss, algae and lichen can develop on roofs where moisture is retained, particularly in shaded or damp areas. Guard Anti-M 24 is a curative and preventative treatment designed to eliminate organic growth and inhibit regrowth. It can be used on roof materials including terracotta, slate and concrete.

For ongoing protection, Guard Industry recommends using Guard Anti-M 24 before sealing, followed by a suitable product from the ImperGuard or ProtectGuard range.

Guard Industry products can be used on a range of suitable porous roofing materials, including concrete roof tiles, terracotta and other porous mineral-based surfaces. 

The correct roof sealer should always be selected according to the roof material, condition and desired result.

Commercial roofs can cover large areas and are exposed to ongoing weather, moisture, pollution and environmental contaminants. 

A suitable roof sealer and maintenance system can help protect porous roofing materials and reduce ongoing deterioration.

Penetrating roof sealers can provide water-repellent protection across extensive porous surfaces without creating a heavy surface film. Guard Industry's outdoor sealer range is designed for applications including roofs, walls, driveways and pavements.

ImperGuard is a practical option where the primary requirement is water-repellent protection for porous roofing materials, while ImperGuard Ultra 4 in 1 provides additional antimicrobial, stain-repellent and consolidating properties.

Water absorption can contribute to staining, deterioration and other moisture-related problems in porous roofing materials. A suitable roof sealer helps reduce water penetration while maintaining the breathability of the substrate.

ImperGuard® is a non-film-forming, breathable water repellent that provides invisible protection without changing the natural appearance of suitable surfaces.

WA Sealers supplies Guard Industry's range of professional cleaning, treatment and sealing products for suitable residential, commercial and architectural applications.

Recommended Guard Industry products for suitable roof applications include:

• ImperGuard: penetrating water-repellent roof sealer
• ImperGuard Ultra 4 in 1: water repellent, antimicrobial, stain-repellent and consolidating sealer
• Guard Anti-M 24: treatment for moss, algae, lichen and other organic growth

Product suitability will depend on the roofing material, porosity, existing coatings and condition of the roof.

A roof should be thoroughly cleaned and prepared before applying a roof sealer. 

Dirt, grime, moss, algae, lichen, efflorescence and other contaminants can affect the appearance and performance of the final treatment.

The best results come from treating roof protection as a complete system: identify the roofing material, remove contamination, treat organic growth where required, allow the surface to dry and then apply the appropriate roof sealer.

Accumulated dirt and environmental deposits can prevent a roof sealer from properly penetrating the substrate. Thorough cleaning helps expose the underlying surface and provides a better foundation for roof sealing.

Guard Industry offers a range of cleaning products for different types of surface contamination, allowing the preparation process to be matched to the condition of the roof.

Organic growth is common on areas of roofing that remain damp or receive limited sunlight. Guard Anti-M 24 is specifically designed to treat moss, algae, lichens and fungi, with both curative and preventative action.

The treatment can be applied to suitable roof surfaces and allowed to work before the dead growth is removed by brushing, washing or natural weathering.

White salt deposits, cement residues and other construction-related contamination can affect the appearance and preparation of roof tiles. 

Guard Remover Eco Efflorescence & Cement is designed to remove efflorescence and cement-based residues from suitable mineral surfaces and can form part of the preparation process before sealing.

After cleaning and treatment, the roof should be allowed to dry thoroughly before applying a penetrating roof sealer. 

Products such as ImperGuard and ImperGuard Ultra 4 in 1 require the substrate to be clean, dry, dust-free and free from grease and cleaning residues before application.
