Critical Roofing Errors to Avoid for Optimal Durability and Safety

by | May 13, 2024 | Blog

In the intricate process of roofing, the distinction between a secure and durable roof versus one plagued by constant issues often lies in the minutiae of the installation practices. A myriad of common mistakes can severely compromise the integrity, functionality, and longevity of a roofing system. This article endeavors to elucidate these critical errors, empowering homeowners with the knowledge to ensure their roofing projects meet the highest standards of quality and craftsmanship.

Nail Placement and Quantity Per Shingle

The foundation of a steadfast roof lies in the precision of its nailing pattern. Each shingle must be affixed with a precise number of nails, neither too few nor excessive, to avoid underdriving or overdriving. Adhering to manufacturer’s specifications, typically requiring five to six nails per shingle, is paramount.Tycos Roofing and Siding, headquartered in Wilmington, DE, exemplifies this commitment by consistently employing six nails per shingle, surpassing industry standards to ensure unmatched roof stability.

The Critical Role of Proper Flashing

Effective water leakage prevention hinges on the correct installation of counter and step flashing. These components are essential where the roof meets vertical surfaces, like walls and chimneys, providing an impenetrable barrier against moisture ingress. Unlike subpar practices that resort to caulking, the employment of reglet flashing, which incorporates a specialized groove at the seam, offers enhanced protection, ensuring a home remains dry and damage-free.

Ventilation and Insulation: The Balance Essential for Roof Longevity

A well-ventilated and insulated attic is crucial for preventing a plethora of issues, from pest infestations to premature shingle degradation. Proper ventilation systems, consisting of intake vents at the soffits and exhaust mechanisms at the ridge, work in tandem with attic insulation to maintain a balanced roof environment. This synergy not only extends the life of the roofing materials but also upholds the integrity of the roof’s warranty, safeguarding the homeowner’s investment.

Ice and Water Shield Placement Beyond Code Requirements

In regions like Delaware, where weather extremes are a commonality, the installation of an ice and water shield is a code-mandated necessity. However, merely meeting the minimum standards is often insufficient. A comprehensive approach extends the waterproof membrane well beyond the required two feet from the warm wall, covering all potential entry points for water, thereby offering superior protection against ice damming and water penetration.

The Importance of Capped Nails or Staples for Underlayment Attachment

Following the 2012 enhancements to the International Residential Contractors code, the attachment of the roof’s underlayment has seen a significant shift towards greater resilience. Utilizing capped nails or appropriately sized staples is non-negotiable, ensuring the synthetic paper underlayment remains securely in place even under the harshest conditions. This practice is a testament to the commitment to quality and durability, emphasizing the importance of detail-oriented craftsmanship in roofing.


Achieving a durable, safe, and efficiently installed roof necessitates a profound understanding of common roofing pitfalls and a steadfast commitment to exceeding standard practices. With an unwavering dedication to quality, as exemplified by the mission of Tycos Roofing and Siding, homeowners can rest assured their roofing projects not only meet but surpass the expectations of durability, safety, and aesthetic appeal.
