ESTIMATING ROOF MATERIALS

Different roofing materials have been used recently to add glamour to a structure. The basics, however, still work with galvanized iron sheets - plain and corrugated. With the standard sizes of GI sheets available, a similar procedure as to area method is used in some components as well as directly counting number of roofing sheets required with the effective width.

Components to be kept in mind while estimating roofing:

  • Smaller gauge is most often used in the roofing material (Gauge 26 corrugated sheet) and thicker for the roofing accessories (usually Gauge 24 plain sheet). 
  • Side laps are between 1-1/2 and 2-1/2 corrugations making the standard effective width of the roofing sheet as 0.70m and 0.60m respectively.
  • End laps can be taken as 0.25 for steep roof slopes and 0.30 for moderate roof slopes.
