The length of ROOFTOP® double wall corrugated roofing profiles can be ordered according to the required specifications. However, custom length orders generally take slightly longer than standard sizes due to additional processing. In terms of width, ROOFTOP® roofing products are currently only available in the standard width and cannot be customized.
Besides those two colors, ROOFTOP® can also be ordered with custom color according to customer’s preference. However, there will be minimum order quantity as well as a slight price difference that varies according to the chosen color. The reason ROOFTOP® comes with this two natural color (white and light blue) is to avoid additional heat absorption. Lighter color tends to not absorb heat as much as darker color, and hence, can help in maximizing heat reduction ability. For further information or inquiries regarding custom color, kindly contact us through email, telephone or WhatsApp.
Several things that you can check in order to verify the authenticity of your ROOFTOP® products are: check the laser-printed ROOFTOP® logo and production code located on the sides of the roofing sheets, check the precision of interlock system, check whether there are no gap left when ROOFTOP® sheets are stacked, and lastly, check whether it has the ability to withstand ample amount of weight without forming any cracks. For further information, please visit this page.
ROOFTOP® does not require special maintenance. To provide you with a peace of mind, ROOFTOP® was designed and formulated to have a long lifespan and minimum maintenance. Rain water will most often wash away the dirt and grime on the upper surface of the roof, so it usually does not require special cleaning. For the bottom surface, in case any dirt remains, gently wipe off with soft cloth. Avoid using brush or other sharp instrument as it may damage the roofing sheet. For more information regarding cleaning, please do not hesitate to contact us.
Many factors affect the service life of ROOFTOP® uPVC roof, some of them includes: surrounding environmental conditions, climate, temperature, and installation.
