As regards roofing installation is concerned, every joints need proper sealing with the use of silicon or other chemicals. However, the general sealants available in the market are not ideally suitable for a longer period. In the course of time, these sealants turn rigid and start either cracking or peeling off resulting to water leakages.
Normally, leakages occur from the end-laps, flashing, ridges, gutter areas, etc.
That's why, Petroguard offers highly effective roof joint sealants suitable for the present metal roofs, especially for the galvalume roofing, PUF panels, double skin sandwich roofing systems, etc.
