Choosing a good roofer is essential for protecting your home. 

With roofing being one of the most expensive and critical home maintenance tasks, a poorly done job can lead to leaks, structural damage, and costly repairs. 

This guide provides a detailed, step-by-step approach to identifying a reliable roofer, evaluating their work during the project, and assessing the final result. 

By focusing on key indicators and red flags, you can make an informed decision.

Why Choosing a Good Roofer Matters

The difference between a good roofer and a careless one may not show immediately, but it will over time. 

A good roofer understands the complexities of roofing systems, local building codes, weather challenges, and safety.

Poor workmanship can lead to costly repairs, and even structural damage. 

A skilled roofer will deliver a roof that performs well over decades, potentially saving you thousands in avoidable problems.

Before Hiring a Roofer: Research and Selection

The foundation of hiring a good roofer lies in thorough research and careful selection. 

Here’s how to start:

Get Referrals

Begin by asking friends, neighbors, or colleagues for recommendations, especially those who have recently had roofing work done.

Research Potential Roofer

Identify at least three qualified roofers to compare. Verify their licensing and insurance:

• Ensure they are licensed to operate, this indicates compliance with local regulations.
• Check for adequate insurance to protect yourself from potential claims.
• Check reviews on trusted platforms like Google Reviews. Look for consistent positive feedback and how the company responds to any negative reviews, as this indicates their professionalism and customer service.

Meet Face-to-Face

Invite potential roofers to your home for an in-person assessment. Discuss the following;

• Materials to be used.
• Scope of work, such as repairs, replacements, or inspections.
• Timeline and manpower needed to complete the job.
• Observe their professionalism: Are they knowledgeable, enthusiastic, and clear in their explanations? Do they answer your questions thoroughly?

Request Detailed Quotes and Contracts

A good roofer should provide a detailed written quote that breaks down:

• Labor costs.
• Material costs.
• Any additional expenses, such as permits or disposal fees.
• Ensure the contract is comprehensive, covering:
  • Safety procedures to protect your property and workers.
  • Liability and worker’s compensation to safeguard against claims.
  • Clean-up methods to ensure the job site is left tidy.
  • Payment schedule, typically requiring only a portion upfront, with the balance due upon completion (avoid contractors who demand full payment upfront).
• Look for warranties on both labor and materials, as this shows confidence in their work. Consider requesting a lien waiver to protect against future claims.
  
• Consider Quality Over Cost: Don’t quickly choose the cheapest bid, as this can indicate cutting corners. Prioritize the roofer’s reputation, experience, and quality of work. 

Compare quotes from multiple contractors, but remember that a slightly higher price may be worth it for peace of mind and long-term durability.

During the Roofing Project: Monitor Progress

Once you’ve hired a roofer, stay engaged to ensure the project is on track. 

Here’s what to look for:

Communication

A good roofer should maintain open and consistent communication. Expect regular updates on the project’s progress, like if there are any delays. 

• Feel free to ask questions at any time—they should be responsive and willing to address your concerns.

On-Site Supervision

If possible, observe the work being done. Look for:

• Professionalism among the crew, such as wearing appropriate safety gear and respecting your property.
• Attention to detail, such as ensuring materials are installed correctly and debris is managed.
• Note whether they take precautions to protect your property, such as using tarps to prevent damage from falling debris.

After the Roofing Job: Evaluating the Work

Once the project is complete, it’s essential to evaluate the work to ensure it meets high standards. Here’s how to tell if your roofer did a good job.

Visual Inspection

Check the roof for an even and uniform appearance

There should be no discolored, drooping, or sagging areas, as these can indicate poor installation or mismatched materials.

The roof should look consistent across all sections, improving curb appeal and ensuring even wear.

If possible, view the roof from a higher vantage point. (But only do this if you’re 100% sure that you can use a ladder to avoid falling off)

Check for Proper Installation

Verify the following key aspects:

Removal of Old Layers

Ensure all old shingles have been removed for a clean, uniform look and to prevent excess weight, which can strain the roof structure.

Quality Underlayment

Confirm the use of high-strength synthetic underlayment (not just felt) for better water resistance and durability.

Proper Flashing

Check for new flashing around pipes, chimneys, and other protrusions. Ensure drip-edge flashing is installed along the roof’s edges, with a lip to direct water into gutters and prevent leaks, mold, and rot. Missing or improper drip-edge flashing can void warranties, as highlighted in the same source.

Shingle Installation

Confirm that shingles are aligned with sufficient overlap and centered over the sheathing. Each shingle should be properly nailed, typically with 4-6 nails per shingle, evenly spaced, depending on wind resistance requirements. Proper nailing prevents damage in high winds.

No Mismatched Materials

Ensure all shingles are the same type and color to avoid uneven aging, which can lead to further repairs down the road.

Cleanliness

The job site should be left clean and free of debris, such as nails, shingles, or other materials. A clean workspace indicates pride in their work and respect for your property.

Warranty and Follow-Up

Ensure the contractor provides warranties on both labor and materials, typically ranging from 5 to 25 years depending on the materials. Ask about follow-up inspections or maintenance services to ensure long-term satisfaction.

Red Flags to Watch For: Signs of a Subpar Roofer

Be cautious of the following signs that may indicate a roofer is not up to standard:

Pressure for Immediate Decisions

Avoid contractors who push for quick commitments, as this can indicate desperation or hidden issues.

Full Payment Upfront

Reputable roofers typically require only a portion of the payment upfront, with the balance due upon completion. Full payment upfront is a red flag.

Lack of Proper Documentation

Ensure they have licenses, insurance, and certifications. A lack of documentation can leave you vulnerable to legal and financial risks.

Poor Communication

If they’re unresponsive or unclear during the hiring process, it’s a warning sign of potential issues during the project.

• Cutting Corners: Watch for signs like not replacing rotted wood before installing new shingles, using subpar materials, or skipping essential steps like installing drip-edge flashing.

Ensuring Long-Term Satisfaction

Choosing a good roofer is an investment in your home’s safety and value. By conducting thorough research, observing their work during the project, and evaluating the final result, you can ensure a high-quality roofing job. 

Take your time to compare options, ask questions, and verify credentials. Remember, a good roofer will stand by their work, communicate effectively, and ensure your satisfaction, providing peace of mind for years to come.
