A KD Sheet is designed to be Virtually Maintenance Free. However, “virtually” doesn’t mean “completely.” Just as you service a premium car to keep it running smoothly, a small amount of care can extend the life of your KDT roof from 20 years to over 30 years. Here is the official KDT India guide to roof longevity.
Post-Monsoon Cleaning
The primary enemy of a roof isn’t just rain; it’s debris. After the heavy Bengal monsoons, leaves, dust, and bird droppings can accumulate in the wide valleys of the sheets.
-
The Risk: This debris traps moisture against the paint, which can lead to localized corrosion over many years.
-
The Fix: Simply use a soft water hose (no high-pressure washers!) to flush out the gutters and valleys once a year.
Inspecting the Fasteners
KD Sheets are held down by specialized screws with rubber washers. Over 5 or 10 years, the intense heat of the sun can cause these washers to dry out.
-
The Check: Every few years, have a technician (or a KDT expert) check if the screws are tight and if the washers are still sealing the holes.
-
The Benefit: This prevents “pinhole leaks” that can damage your interior ceiling.
Handling with Care
If you ever need to walk on your roof for antenna repair or cleaning, always wear soft-soled shoes and walk in the “valleys” (the flat parts), never on the “ribs” (the high parts). This preserves the Anti-Corrosion layer and prevents denting.
Conclusion
A KD Sheet is built for the long haul. With these three simple steps, you can ensure that your roof stays vibrant, strong, and leak-proof for your children and grandchildren.
