### Industry-Specific Reference Requirements
Different types of construction work require specialized knowledge and skills, making it essential to verify contractor references that specifically relate to your project type. Understanding industry-specific requirements helps you ask the right questions and evaluate relevant experience appropriately.
For roofing projects, request references from customers who had similar roofing systems installed in comparable climate conditions. Ask about leak performance during severe weather, material durability over time, and whether warranties have been honored for any issues. Roofing work is particularly weather-dependent, so references should include projects completed during different seasons.
Kitchen and bathroom renovations require references that demonstrate experience with plumbing, electrical work, tile installation, and coordination of multiple trades. Ask references about functionality of finished systems, quality of tile and fixture installation, and whether all systems work properly over time. These projects also involve significant disruption, so ask about contractor cleanliness and disruption management.
HVAC system installations require references that can speak to system performance, energy efficiency improvements, and contractor knowledge of proper sizing and installation procedures. Ask whether systems perform as expected, whether promised energy savings materialized, and whether installation was completed without damage to existing structures.
Electrical work references should demonstrate contractor knowledge of current codes, proper installation procedures, and safety protocols. Ask about permit and inspection processes, whether work passed inspections on the first attempt, and whether electrical systems function reliably without problems.
Foundation and structural work requires references that can verify contractor experience with similar soil conditions, building types, and structural challenges. Ask about long-term stability, whether structural problems were actually resolved, and whether contractor warranties cover potential settling or movement issues.
Exterior work including siding, windows, and doors requires references that demonstrate understanding of local weather challenges, proper installation for energy efficiency, and material selection appropriate for local conditions. Ask about performance during extreme weather and whether installations remain watertight and energy-efficient.
Flooring installations require references that can speak to material selection, subfloor preparation quality, and installation precision. Different flooring types have specific installation requirements, so verify that contractor experience matches your flooring choice. Ask about long-term performance and whether floors remain level and secure.
Plumbing projects require references that demonstrate code compliance, proper installation procedures, and reliable system performance. Ask about water pressure, drainage effectiveness, and whether installations remain leak-free over time. Plumbing problems can cause extensive damage, making reference verification particularly important.
Specialty trades such as stone work, custom millwork, or historic renovation require highly specialized skills and experience. References should demonstrate similar complexity projects and appropriate techniques for your specific requirements. Ask detailed questions about craftsmanship, material selection, and problem-solving approaches for challenging installations.
