Frequently Asked Questions

1.  What is roofing sheet made of fibre cement?

Ans - These sheets are created using a special fibre mesh technology and the highest grade cement and fibre. You get a product with long-lasting value because of the strict quality control procedures used during the production process.

2. What is the lifespan of a fibre cement roof?

Ans - If properly placed and maintained, fibre cement siding can last up to 50 years. This sturdy siding's initial investment pays off for many years. Your house will look nicer and be weatherproof thanks to it. 

3. Fiber cement sheeting is water resistant?

Ans - Fibre cement is resistant to rotting, warping, water damage, and termite infestation. Fiber cement offers the same sleek appearance as timber cladding while being more resistant to heat and moisture damage and requiring less frequent maintenance. 

4. What drawbacks do cement roofs have?

Ans - Concrete is more susceptible to weathering than comparable products, and it can crack and become stained more quickly than, say, slate or clay tiles. This propensity can also promote the development of lichen and moss, which, if unchecked, can harm your roof over time.
