The County Roofing Systems Custom Installation Process

The Foundation of Quality: Proper Preparation

The first step in the roof installation process is a thorough inspection by a qualified roofing contractor.

Before we install a single shingle, we assess your roof deck, measure roof dimensions, identify any structural issues, and plan for proper ventilation with roof vents.

Here’s what makes our installation process different:

1. Complete Tear-Off When Needed

A tear-off (complete removal of the old roof) is often recommended for a longer-lasting and more secure roof installation process. We strip away old shingles, underlayment, damaged drip edge, and worn metal flashing down to the roof deck. This reveals hidden problems before they become leaks.

Many homeowners discover rotted wood, missing shingles, or water infiltration damage during tear-off that would have caused serious problems if left hidden under new shingles. While some contractors push overlay installations to save money, we recommend what’s right for your home—not what’s fastest.

2. Roof Deck Inspection & Repair

The roof deck must be inspected for damage and repaired if necessary before installing underlayment. We check every inch of your roof surface for soft spots, rot, or warped boards. Any damaged sections get replaced with new wood properly fastened to your roof structure.

This step is critical. Even premium architectural shingles won’t perform correctly on a compromised deck. We’ve seen too many roof replacement projects fail early because contractors skipped this fundamental step.

3. Ice and Water Shield Protection

We install ice and water shield along eaves, valleys, and around roof penetrations where leaks most commonly start. This waterproof underlayment creates a secondary barrier that prevents water infiltration even if wind-driven rain gets under shingles.

In Long Island’s climate—with nor’easters, heavy snow, and ice dams—this protection is essential. We extend coverage beyond minimum code requirements because we know what Long Island weather does to roofs over 20-30 years.

4. Quality Underlayment Installation

After protecting vulnerable areas, we install underlayment across the entire roof. This layer works with your shingles to create a complete weather barrier. We use premium synthetic underlayment that won’t tear or deteriorate like old felt paper.

Proper underlayment installation includes overlapping seams correctly, securing it against prevailing winds, and ensuring it lies flat without wrinkles that could telegraph through shingles.

5. Drip Edge & Flashing

We install drip edge along the rake edge and bottom edge of your roof before shingle installation begins. This directs water away from fascia boards and prevents rot. Metal flashing goes around chimneys, skylights, and other roof penetrations to prevent leaks.

Quality flashing work separates roofs that last 15 years from those that last 35 years. We use heavy-gauge materials and roofing cement at critical junctions to create watertight seals.

Installing Your New Roof: Precision Matters

The installation process consists of several critical steps that must be followed in the correct order to ensure a watertight, durable roof.

6. Starter Shingles & First Course

Starter shingles create a critical base for your first course of full shingles. We install starter strip along the lower edge and rake edge, ensuring the adhesive strip seals properly to prevent wind uplift.

The first shingle and first course set the pattern for your entire roof. We snap chalk lines to maintain straight rows, check alignment constantly, and ensure proper shingle placement from the start. Beginning the first course correctly determines whether your roof looks professionally installed or DIY.

7. Shingle Installation Course by Course

Working from the bottom edge upward toward the roof’s peak, our roofing crew installs each shingle course with precision. We follow the prevailing wind direction in your area to optimize shingle performance and prevent wind-driven rain infiltration.

Each architectural shingle gets properly fastened with roofing nails placed according to manufacturer’s specifications. We use the correct number of nails, position nail heads in the designated nailing zone, and ensure every fastener penetrates the roof deck—not just underlayment.

Standard shingles require four nails each, but high-wind areas may need six. We know which roofing components need extra fasteners based on your home’s location and roof pitch.

8. Valley & Hip and Ridge Installation

Closed valleys require careful shingle placement to create watertight channels. We weave or cut shingles along the valley centerline, seal all edges, and ensure proper water flow without creating damming spots.

Hip and ridge caps require special attention. We install ridge cap shingles along all hips and ridges, using cap nails driven at the proper angle. These hip and ridge caps must seal correctly while allowing for thermal expansion and contraction.

9. Final Inspection & Quality Check

We conduct a final inspection after the roofing job is complete to check for any issues. This includes:

  • Verifying all nail heads are flush and properly placed

  • Checking every roof penetration is sealed correctly

  • Ensuring proper shingle course alignment across the entire roof

  • Confirming drip edge is secure along every edge of the roof

  • Testing that roof vents are properly installed and flashed

  • Looking for any missing shingles or installation errors

Roofing work can be dangerous, especially on higher structures. A third of construction-related fatalities occur from falls off roofs, underscoring the importance of proper safety measures.

Our professional roofing crew uses safety equipment on every roofing installation project—ladders secured properly, fall protection systems, and scaffolding when needed.

Contractors protect the site during roof installation by setting up tarps and scaffolding. We also protect your landscaping, driveway, and outdoor living areas.

High noise levels and property disruptions are common during roof installation due to equipment and debris, but we minimize impact and clean thoroughly every day.

Choosing the Right Roofing Materials

Understanding Your Options

The average roof lasts between 20 and 25 years, which can change depending on various factors—primarily the roofing materials you select and the quality of installation.

Asphalt Shingles

Asphalt shingles are the most affordable roofing option with a lifespan of 15-30 years. They’re popular for their durability and ease of installation. Asphalt shingles have a shorter lifespan of 20-30 years and are easy to install, making them the most common choice for residential roofing projects.

We install both standard three-tab shingles and architectural shingles. Architectural shingles offer better wind resistance, more dimensional appearance, and longer warranties than basic shingles.

Metal Roofing

Metal roofing is durable with a lifespan of 40-70+ years and reflects heat, making it energy-efficient. Metal roofing offers excellent long-term value and energy savings despite a higher upfront cost.

Reflective “cool roofs” can reduce cooling costs by up to 25% by reflecting sunlight. If energy efficiency matters to you, metal roofing deserves serious consideration for your new roofing project.

Tile & Specialty Materials

Clay and concrete tiles are very durable and aesthetically pleasing for Spanish/Mediterranean styles but are heavy and costly. Clay tiles are ideal for intense heat but may crack in freezing weather, making them less suitable for Long Island’s climate.

Slate roofing lasts over 50 years, has a premium appearance, but is expensive and heavy. Wood shakes and shingles provide a natural look but have higher maintenance needs and a risk of fire.

Composite roofing materials are designed to mimic slate or wood but are lighter and more affordable—offering the aesthetic you want without structural reinforcement requirements.

Material Selection Guidance

We help you choose roofing materials based on:

  • Your budget and long-term cost considerations

  • Architectural style and neighborhood aesthetics

  • Climate requirements for Long Island weather

  • Energy efficiency goals

  • Maintenance preferences

  • Warranty coverage needs

Every roofing project gets customized material recommendations based on your specific situation—not a one-size-fits-all approach.
