Roof Sealer is a water-based breathable sealer which creates a water-repelling surface on porous roof tiles. It is suitable for sealing porous concrete tiles, slate tiles, clay-based tiles, sandstone, slate & other natural stone. This roof tile sealer is a low odour water-based impregnating sealer which allows 100% moisture vapour transmission. Roof Sealer resists organic staining, rainwater penetration, carbon deposits & inhibits organic growth.
This protective roof tile sealer will last 10 years or more due to its powerful formulation. Sealing porous roof tiles prevents water penetration, organic staining and carbon deposits from airborne pollution.
Apply once to porous roof tiles with a second lighter treatment applied within approximately 40 minutes of the first. Dense surfaces (like slate) may only require one application of product. Redistribute any excess product with a brush or roller to avoid pooling or puddling on low-angled roofs.
This water-based roof tile sealer will penetrate the surface of the tile. Roof Sealer does not alter the appearance of the material being sealed as it is not a surface coating, it is a penetrating sealer which soaks into the pores of the surface, therefore seals from within.
This product does not alter colour or create a visible sheen or shine. It can be applied to older or new roof tiles. We recommend pre-cleaning older tiles with Floorseal Roof Cleaner Bio Wash to kill moss & algae.
Please note: This product is not suitable for filling obvious holes or cracks.
Available in 5 litre, 10 litre & 20 litre containers with free economy shipping and express delivery shipping options. Samples are available.

Roof Sealer allows full water vapour transmission so no trapped moisture or moisture clouding issues can occur.
Roof Sealer is designed to soak into the surface and any obvious excess is to be removed. Roof Sealer leaves the treated surface with a totally natural appearance. The sealer seals from within the pores of the tiles. It is not a film or ‘skin’ forming product so no sheen or shine.
As long as the roof tile is porous you can apply this sealer to it.
If the roof is new you do not need to pre-clean the tiles.
As a minimum we strongly recommend cleaning your roof with Floorseal Roof Cleaner Bio Wash prior to sealing. This product can be used at a later date to maintain your roof and further inhibit organic growth.
Some surfaces are more porous than others. Typically a coverage rate of 5m2 per litre for porous surfaces is achieved. But you may achieve 10m2 on dense surfaces like slate or some clay-based tiles.
This product can be sprayed on using a low pressure sprayer. Redistribute any sealer which is still visible on the surface after approximately 20-30 minutes.
On porous surfaces the sealer will simply sink in leaving no excess – follow up with a lighter application of product to ensure full protection.
Roof Sealer is a water-based impregnating sealer. It penetrates the surface of the tile, so is non-film forming. The polymers sit within the pores of the treated surface creating a water repelling barrier. Roof Sealer is 100% breathable.
Impregnating sealers do not form a skin/film/lacquer so cannot trap moisture. They do not alter colour or create a sheen so retain an unaltered natural appearance. Impregnators do not ever require stripping they can be reapplied, typically when the tile begins to display some porosity.
Acrylic-based sealers have the potential to trap moisture under the seal. Breathable sealers like Roof Sealer repel rain water, resist dirt, carbon deposits & inhibit organic growth without trapping moisture.

No, this sealer is an impregnating sealer, so not suitable for sealing cracks and holes. If the roof is leaking through physical damage caused by cracking or holes forming – this sealer is not suitable for making repairs.
Floorseal Roof Sealer is a non film or ‘skin’ forming waterproofer. It does not form a coating or layer (similar to a lacquer). It repels moisture which is soaking through the pores of the tiles then into the building.
