3. Labor Costs Labor is a significant component of the overall cost. The skill level required for installation, local wage rates, and the complexity of the work can all drive labor costs up. Hiring experienced roofing contractors may lead to higher initial costs but can ensure a quality job that minimizes future repairs.

Galvanization involves coating iron or steel with zinc to prevent rusting. While this treatment extends the life of pipes, it also alters their surface texture. The roughness created by the galvanization process can increase the friction factor compared to smooth-walled pipes. This increase implies greater energy requirements for pumping fluids through galvanized pipes, particularly in systems that rely on water or other low-viscosity fluids.
