Explain in detail two variables that can effect an estimate for roofing?

Solution

Roof supporting structure is taken seperately in cum, and the lime concrete terracing is computed in sq.m with thickness specified, under a seperate item including surface rendering smooth.

The variable which are influence the estimate are

1.Roof type

The type of roof on your home greatly influences repair costs. Roofs can be flat or sloped, high or low pitch, metal or shingled — or even something more unique. Roofing material costs vary greatly between roof types, and some require more labor and materials than others.

2. Roofing repair permits

The city or town where you live can affect your roofing repair costs as well. The roofer may need to pull permits for repairs. The price of the permit may be a flat rate in your area, or it could be based on your home\'s size or value.

In some coastal areas, there is a separate permit to protect your home from hurricanes and tropical storms.
