Hiring a professional roofer is akin to selecting a guardian for your home. Just as the roof is a bulwark against the caprices of Mother Nature, the roofer you choose is entrusted with the responsibility of ensuring this defensive structure is in optimal condition. While the task of hiring a professional roofer may appear daunting, it need not be so. By adopting a methodical approach that incorporates key considerations, it is possible to engage a roofer who is not only competent, but also well-suited to your unique needs.

The first critical step in the hiring process involves sourcing for potential roofers. Similar to the Pareto Principle, also known as the 80/20 rule, one can reasonably expect that a mere 20% of local roofers will possess 80% of the relevant experience, skills and qualifications. These are the professionals you want to identify. Leveraging local networks, online reviews and the Better Business Bureau (BBB) can be effective ways of generating an initial list of prospects.

Once you have developed a list of potential candidates, the subsequent step is to evaluate their qualifications. This is akin to what the psychologist David McClelland referred to as "competency-based assessment". The goal here is to evaluate roofers based on their skills and experience rather than their credentials alone. By doing so, you can ensure that the roofer you eventually hire is more than simply a paper tiger.

Key qualifications to look for include state licensing, workers' compensation and liability insurance, a solid business reputation and a wealth of experience in the type of roofing system you have. It is also crucial to verify these qualifications. The BBB, for instance, is a valuable resource for checking a company’s business reputation.

After narrowing down your list based on qualifications, the next step is to solicit bids from the remaining candidates. In economics, this process is likened to a reverse auction, where service providers compete by submitting progressively lower bids until one emerges as the ‘winner’. However, it is vital not to let cost be the sole determinant. A bid should detail the scope of the work, materials to be used, and timeframe for completion. It is also wise to specify that the roofer should adhere to the manufacturer’s instructions to keep the warranty valid.

Following the reverse auction process, it is time to dive deeper into the remaining candidates' modus operandi. A roofer’s workmanship and the way they conduct their business can have a significant impact on the outcome of your project. This evaluation might involve asking for references from past clients, examining completed projects, and evaluating their client service approach.

Perhaps the final and arguably the most important step is to ensure all agreements are detailed in a contract. This is important for protecting your rights as a consumer. The contract should detail all aspects of the project, including cost, payment structure, project timeline, materials to be used, safety precautions, clean-up methods after completion, and any warranties or guarantees.

Hiring the right professional roofer involves a blend of methodical research, application of key economic and psychological principles, and due diligence. The roof is an indispensable part of your home, and as such, requires the expertise and skill of a true professional. By adhering to this systematic approach, you can ensure that the protection of your home is placed in capable and trusted hands. Remember, the professional you hire will not only impact the quality of your roof, but also the overall value and safety of your home.
