Crown Tiles Vs Long Span Roofing (cost) by saydfact(m): 2:56pm On Jan 27, 2017 |
Hi All - A follower asked for comparison between him using LONG SPAN and NIGERITE CROWN TILES in respect to cost implication. Our calculation was based on a particular 3 bedroom design; the different factors in the roofing was: 1. In the Crown Tile we required double the PURLINS needed compared to the Aluminum Long Span. 2. The total surface area to be covered was 190m2 The Calculation is Shared below: CROWN TILES VS LONG SPAN ROOFING (COST) The Crown Tiles comes in sizes of 420mm x 320mm; this implies that there would be an increase in the numbers of purlin (2x3 - hardwood) used by 50%. The reason is simple: While Long Span come factory cut to required length of buyer (hypotenuse) of the roof, allowing a standard spacing of about 750mm - 900mm; the Crown Tiles come in already cut smaller sizes, hence closer spacing is required at about 270mm - 300mm hence the doubling. From the Aluminum Calculation we had: Purlin (2x3) = 65 @ N450 = 29250 we will just double that to: A. Purlin (2x3) = 130 pcs @ N450 = N58,500:00K B. Cost of Roofing with Crown Tiles: What quantity of this product would we need to cover the 190m2 space generated from our attached design? 0.42 * 0.32 = 0.1344 ( in a meter square we have about 8pcs ) but remember they lap over each others so we end up using 10 pcs per meter square. Hence if 10 pcs covers 1m2; we have 10 pcs x 190m2 = 1900 pcs to be brought. (Always add for waste 10% on this occasion) = Approx 2000 pcs Cost of One Crown Tile = N305 hence; Total Cost of Roofing Tiles = N610,000 NOTE: Cost of Roof Covering using ALUMINUM LONG SPAN WAS = N2200 x 190 = 418,000 The Eaves and Facial board being covered with Aluminum in the previous calculation resulted in an overall cost of N867,300 COST DIFFERENCE: TOTAL COST IN ALUMINUM = N418,000 + N29,250 (Roof covering + Purlin) = N447,250 : 00k TOTAL COST IN CROWN TILES = N610,000 + N58,500 (Roof covering + Purlin) = N668,500 : 00k MY VERDICT: QUALITY ALUMINUM (0.55mm thick) IS CHEAPER.
