Why Roof Installation Matters for Your Home
A professional roof installation is a critical home improvement project that protects your most valuable investment. Whether you’re dealing with an aging system, storm damage, or planning a proactive upgrade, understanding the process helps ensure you make informed decisions. For Delaware homeowners, choosing quality materials and proper installation techniques is especially important to protect against our coastal climate. This guide from the experts at First State Roofing & Exteriors will walk you through everything you need to know.
Key Roof Installation Facts:
- Average Cost: $8,000 nationally (typically $5,500-$11,000)
- Timeline: 1-3 days for most residential projects
- Labor vs Materials: 60% labor costs, 40% material costs
- ROI: Returns approximately 60% of investment at resale
- Lifespan: 25+ years for asphalt shingles, 50+ years for metal
A properly installed roof involves multiple layers working together—from the structural deck and underlayment to the shingles and flashing. Each component must be installed correctly to prevent leaks, ensure energy efficiency, and maximize your roof’s lifespan. The process requires careful attention to safety, weather conditions, and local building codes, which is why professional oversight is crucial.
Planning Your Project: What to Know Before You Start
Before diving into your roof installation project, proper planning can save you money and ensure the best results. This involves understanding when to replace your roof, what drives costs, and how to choose the right materials and timing for your Delaware home.
When to Replace vs. Repair Your Roof
Deciding between repair and replacement can be challenging. Age is a primary indicator. Most asphalt shingle roofs have a lifespan of 20-25 years; if yours is approaching this age, it’s wise to plan for a replacement.
Look for these warning signs:
- Curled, cracked, or missing shingles indicate widespread wear.
- Bald spots where protective granules have worn away, often collecting in your gutters.
- Dark streaks or moss growth, which can signal trapped moisture.
- A sagging roof deck, a serious structural issue requiring immediate attention.
- Leaks or water stains on your ceiling, which are clear signs of a breach.
If you’re seeing multiple signs or your roof is past its prime, a full replacement is usually more cost-effective than ongoing repairs.
Key Factors Influencing Your Roof Installation Cost
A new roof installation is a significant investment. The national average is around $8,000, but your final cost will depend on several factors.
- Roof Size and Complexity: A large, steep roof with dormers and valleys will cost more than a simple, low-slope roof.
- Labor and Materials: Labor typically accounts for 60% of the cost, with materials making up the other 40%. Skilled installation is essential for a long-lasting roof.
- Material Choice: Your choice of material significantly impacts the budget. Asphalt shingles are the most common and affordable option, lasting about 25 years. Metal roofing costs more upfront but can last 50-75 years, offering excellent long-term value. Other options like wood shingles, rubber, and slate offer different aesthetics and lifespans at varying price points. You can explore different roofing types to see what fits your home and budget.
- Hidden Damage: Sometimes, removing old shingles reveals rotted decking that must be replaced, adding to the cost. A thorough inspection helps minimize these surprises.

Choosing the Best Materials and Time of Year
Selecting the right material involves balancing budget, aesthetics, and durability. Asphalt shingles are a popular, reliable choice. For superior longevity and energy efficiency, consider our durable metal roofs, which can help reduce cooling costs.
Timing your installation is also important. Spring and fall offer ideal weather conditions in Delaware. Temperatures between 50-80°F are best for asphalt shingles, allowing them to seal properly without becoming too brittle or soft. Avoiding extreme weather ensures the safety of the crew and the quality of the installation, helping your roof installation proceed smoothly.
The Roof Installation Process: A Step-by-Step Guide
Understanding the actual roof installation process helps you appreciate the precision involved in protecting your home. Each phase builds upon the last to create a durable, weatherproof system. Here’s a look at what our professional roof installation services entail.
Step 1: Safety, Tear-Off, and Deck Preparation
Safety is our first priority. Our crews use OSHA-compliant fall protection gear, including harnesses and anchors. We also protect your property by laying tarps to catch debris and protect landscaping.
The tear-off involves removing all old shingles, felt paper, and nails. We then conduct a thorough inspection of the roof deck, looking for any signs of rot or damage. Any compromised sheathing is replaced to ensure a solid foundation for your new roof. This step is non-negotiable for a quality installation.
Step 2: Underlayment and Flashing
With a clean deck, we install the underlayment, which acts as a secondary water barrier. We prefer high-quality synthetic underlayment for its durability. In critical areas like eaves and valleys, we install a self-adhering ice and water shield for extra protection against ice dams.
Next, we install a metal drip edge to direct water away from your fascia. Finally, flashing is carefully installed around chimneys, vents, skylights, and in valleys. This custom metal work is critical for preventing leaks at the most vulnerable points of your roof.
Step 3: Shingle and Ridge Cap Application
This is where your new roof takes shape. We begin by installing starter shingles along the eaves to provide a secure, sealed edge. The main field shingles are then installed from the bottom up, following a precise nailing pattern and staggering the joints to ensure a watertight and uniform appearance. We use chalk lines to keep every row perfectly straight.
The final touch is the ridge cap installation. These specialized shingles cover the peaks and hips of your roof, which bear the brunt of the weather. We use longer nails to secure them firmly to the roof deck, providing a durable and attractive finish.
Step 4: Sealing, Cleanup, and Final Checks
Finishing touches are key to a long-lasting roof. We seal all exposed nail heads on flashing and the final ridge cap with a high-performance sealant like Lexel. This provides a durable, flexible seal that withstands Delaware’s weather.
Our commitment to professionalism includes a thorough final site cleanup. We use magnetic sweepers to collect stray nails and remove all debris, leaving your property pristine. We conclude with a final inspection, walking the entire roof to ensure every detail meets our high standards and inviting you to review the finished work.
Key Project Considerations
Beyond the basic steps, several factors are crucial for the success of your roof installation. These details often separate a good roof from a great one.
Tools and Materials Required
A professional roof installation requires a host of specialized tools and materials. While homeowners don’t need to own these, understanding what’s involved highlights the complexity of the job. Our crews are equipped with everything from pneumatic roofing nailers and pry bars to circular saws for deck repairs. Most importantly, we use comprehensive safety equipment, including harnesses and properly secured ladders.
Material quality is just as critical. Beyond the shingles themselves, we use high-performance underlayment, a self-adhering ice and water shield, hot-dipped galvanized roofing nails, and durable metal for drip edge and flashing. Using inferior materials in these key areas is a common cause of premature roof failure, which is why we never cut corners.
Project Timeline and Attic Ventilation
A typical residential roof installation takes just 1-3 days. An average-sized home can often be completed in two days—one for tear-off and prep, and one for installation. This timeline can be affected by factors like roof complexity, weather conditions, and any unexpected deck repairs that may be needed.
One of the most critical,, aspects of a roofing system is attic ventilation. A properly balanced system of soffit and ridge vents allows your attic to breathe. In summer, this prevents heat buildup that can cook shingles from below and shorten their lifespan. In winter, it prevents moisture accumulation that can lead to mold and rot. Proper ventilation not only protects your roof but also improves your home’s energy efficiency, working alongside roof insulation to lower your utility bills.
DIY vs. Hiring a Professional Roofer
Deciding whether to tackle a roof installation yourself or hire a professional is a major decision. While the potential savings on labor are tempting, the risks are significant.
Can a Homeowner DIY a Roof Installation?
Technically, a homeowner can install their own roof, especially on a simple, low-pitched structure. However, the reality is that roofing is a demanding and dangerous job. The primary risk is safety. Roofing is one of the most hazardous construction trades, and working at height without proper fall protection equipment and training can lead to serious injury.
Beyond safety, there’s a high risk of performance issues. Improper nailing, incorrect flashing installation, or poor underlayment application can cause leaks and water damage that cost far more to fix than the initial savings. Furthermore, most manufacturer warranties are voided if the materials are not installed by a certified professional according to strict specifications. The need for specialized tools and experience to handle unexpected issues like deck rot adds to the challenge.

Hiring a certified professional for your roof installation is an investment in quality, safety, and peace of mind. Here’s what you get when you work with a company like First State Roofing & Exteriors:

Frequently Asked Questions about Roof Installation
Homeowners considering a roof installation often have similar questions. Here are concise answers to some of the most common inquiries we receive.
How long does a new roof last?
The lifespan of your roof primarily depends on the material and the quality of the installation.
- Asphalt shingle roofs, the most popular choice, typically last 20-25 years.
- Metal roofs are a long-term investment, often lasting 50 years or more.
- Wood shingles generally provide 20-25 years of service.
- Rubber roofs can last 30-50 years.
Proper installation and adequate attic ventilation are just as crucial as the material itself for maximizing your roof’s lifespan, especially in Delaware’s climate.
Can you install a new roof over an old one?
While technically possible, installing new shingles over an old layer (a “roof-over”) is a practice we strongly advise against. A complete tear-off is always the best approach for several reasons:
- Hidden Damage: It allows us to inspect the roof deck for rot or other issues that would otherwise be covered up.
- Excess Weight: A second layer of shingles adds significant weight that your home’s structure may not be designed to support.
- Warranty Issues: Most manufacturers will void their material warranties if the shingles are not installed on a clean, properly prepared deck.
A full tear-off ensures your new roof has a solid foundation and will perform as expected for decades.
What kind of warranty should I expect?
A professional roof installation should come with two distinct warranties to protect your investment:
- Manufacturer’s Warranty: This covers the roofing materials against defects. The length and terms vary by product, from 25-year warranties for some shingles to limited lifetime coverage for others.
- Workmanship Warranty: This is the contractor’s guarantee on the installation itself. A reputable roofer will offer a warranty covering any issues that arise from the installation process, typically for a period of 5-10 years or more.
Always get both warranties in writing and understand the terms before your project begins.
