How to Tell Difference Between a Good Roof Installation vs a Bad One

In a fast-paced environment like Arizona, roof replacements are a common necessity. For many roofing contractors, efficiency is paramount, often leading to expedited installations. While timely completion is important, homeowners must be aware of the potential pitfalls associated with hasty roof installation. Understanding the distinction between quality and subpar roofing work is essential for ensuring the longevity and integrity of your roof.

It is vitally important to do your research before hiring a roofing contractor (as there are many frauds out there). Familiarizing yourself with the indicators of high-quality roofing can clarify why some reputable roofers may charge a premium for their services and why certain projects may take longer than expected. Ultimately, speed does not always equate to quality.

When overseeing your next roof installation, consider the following key aspects:

1. Roof Sheathing (Decking)

Quality roofers prioritize the condition of the roof decking during the demolition process. Roof sheathing, located beneath the underlayment and attached to the rafters, should be preserved as much as possible. Although some damage may occur during the removal of stubborn nails, maintaining the overall integrity of the decking is crucial. Rushed work can lead to bends, nicks, and an uneven surface, increasing the risk of leaks. Various materials are available for roof decking, including:

– Elongated Wooden Boards: Historically common before plywood became prevalent, these boards are still used in some southwestern roofs.

– CDX Plywood: A strong and durable option, CDX plywood is layered to prevent warping and is favored for its strength.

– Oriented Strand Board (OSB): Known for its affordability and durability, OSB is a popular choice among builders.

– Metal Decking: Primarily used in commercial applications, metal offers durability and fire resistance.

– Concrete Decking: An alternative for low-slope roofs, concrete is gaining popularity in commercial settings.

– Exterior Gypsum Board: A less expensive option, though it is less water-resistant and has a shorter lifespan.

2. Thorough Inspection of Roof Decking

A reputable roofing contractor will conduct a comprehensive inspection of the roof for any signs of mold, water damage, or decay. Any identified issues should be addressed promptly, with the contractor communicating any necessary adjustments to the homeowner regarding costs for additional materials and labor. Neglecting to replace damaged wood can result in water pooling and leaks post-installation.

3. Removal of Old Roof Nails

In high-wind areas like Arizona, it is recommended that roofers use at least five nails per shingle. During a complete roof demolition, the removal of thousands of nails is required. Any protruding nails after the underlayment is laid can compromise the integrity of the installation, making it essential for a diligent contractor to ensure a smooth roof deck.

4. Proper Installation of Underlayment

Underlayment serves as a critical water-resistant layer and must be installed on a clean, dry, and smooth roof deck. Any damage or improper installation can hinder its effectiveness against the elements. Guidelines for underlayment installation include ensuring it overhangs the eaves and rake edges adequately.

5. Correct Installation of Roof Flashing

Compliance with Arizona regulations require proper installation of roof flashing around vents, chimneys, and other roof openings. A watertight seal is essential to prevent leaks, and the use of durable caulking is crucial for sealing any gaps.

6. Utilization of Quality Roofing Materials

The use of damaged or compromised roofing materials is unacceptable. Contractors should source new materials from reputable suppliers, ensuring that all components are in optimal condition to protect your home.

7. Roof Preservation During Storms

If a roof installation extends beyond one day, reputable contractors will take precautions to protect exposed areas from impending storms. Roof tarps should be securely fastened to prevent damage during adverse weather conditions.

8. Installation of Roof Fascia and Drip Edges

Proper installation of fascia is vital, and any signs of damage should be addressed immediately. Drip edges, made from materials such as aluminum or copper, are essential for directing water away from the fascia and into gutters. Knowledge of the correct installation procedures for both rake and eave drip edges is critical for optimal performance.
