Evaluating Existing Roof Conditions


Before installing a metal roof over composite materials, it's vital to assess the condition of your existing roof. Understanding the integrity of your current roofing system can help you make informed decisions and ensure a successful installation.


Assessing Shingle Roofs


Start by inspecting the existing shingles for signs of damage or wear. Look for curling, cracking, or significant granule loss, which can indicate that the asphalt shingles have reached their limit. If any shingles are missing or damaged, they should be addressed before proceeding.


Check the underlying structure for any signs of water damage. Soft spots or sagging areas may point to underlying issues that could compromise structural integrity. If you find extensive damage, a complete tear-off may be necessary for a successful installation. D&G Exteriors specializes in evaluating and repairing roofing systems, ensuring a solid foundation for your new metal roof.


Importance of Regular Inspections


Regular inspections play a crucial role in maintaining your roof's health. Schedule routine checks at least twice a year and after severe weather events. This proactive approach helps identify minor issues before they escalate, saving you money in the long run.


During inspections, pay attention to flashing and gutter conditions, as these can affect roof performance. Ensuring these elements are intact will help prevent water infiltration. For comprehensive inspections, trust D&G Exteriors, known for thorough assessments and quality service in the Boston area.

Preparing for Metal Roof Installation


Before installing a metal roof over composite shingles, careful preparation is crucial. This process involves selecting suitable metal panels, considering underlayment, and installing furring strips. Each of these elements plays a vital role in ensuring a successful installation and long-term durability.


Choosing the Right Metal Panels


Selecting the appropriate metal panels is essential for your roofing project. There are various styles available, such as standing seam or corrugated panels, each with unique benefits.


  • Material Options: Common materials include steel, aluminum, and copper. Steel is popular for its strength and affordability, while aluminum offers excellent corrosion resistance.

  • Gauge: The thickness of the metal panels, measured in gauge, impacts durability. A lower gauge number indicates thicker metal, which can withstand harsh weather better.

  • Finish Options: Consider finishes such as painted or galvanized coatings to enhance longevity and aesthetics.


D&G Exteriors provides a range of high-quality metal panels that can meet your specific needs in the Boston area.


Underlayment Considerations


Underlayment acts as a protective layer between the existing roof and new metal panels. It plays a critical role in preventing moisture infiltration.


  • Types of Underlayment: Use synthetic underlayment for superior water resistance or felt paper as a cost-effective alternative.

  • Installation: Make sure to install the underlayment in an overlapping manner, commencing from the lowest part of the roof and working upward. This will minimize the risk of leaks.

  • Ventilation: Ensure proper ventilation by allowing air to circulate underneath the metal, which helps manage roof temperature and moisture buildup.


Choosing quality underlayment will contribute to extending the lifespan of your metal roof.


Installation of Furring Strips


Furring strips create a level surface for metal panels and allow for proper drainage.

  • Material Selection: Use treated wood or metal strips to resist moisture and prolong durability.

  • Spacing: Install strips approximately 24 inches apart, depending on the panel width. Proper spacing will ensure stability and support.

  • Attachment: Secure furring strips to the existing roof using corrosion-resistant screws to prevent damage in the long term.


This foundation is essential for a strong and effective metal roof installation.

Benefits and Longevity of Metal Roofs


Metal roofs offer several advantages that enhance their longevity and value. Understanding these benefits will help you make an informed decision about your roofing needs.


Advantages of Metal Over Shingles


Installing a metal roof over shingles provides durability and strength. Metal roofs can last 40 to 70 years, far outpacing traditional shingles that typically last 15 to 30 years. This longevity means fewer replacements and less waste, improving your home’s environmental footprint.


Additionally, metal roofs are weather-resistant, standing up to heavy rain, snow, and extreme temperatures. They resist wind uplift, making them a reliable choice in coastal or storm-prone areas. Metal roofing also does not crack or warp, which can happen with asphalt shingles over time. These factors combined make metal roofs a practical choice for long-term investment.


Cost-Effectiveness and Maintenance


Although the initial cost of a metal roof is higher than shingles, its cost-effectiveness becomes evident over time. Lower maintenance requirements mean reduced expenses. Metal roofs typically require only periodic inspections and cleaning to maintain their appearance and performance.


Moreover, metal roofs are energy-efficient, reflecting sunlight and potentially reducing cooling costs in warmer months. This efficiency can lead to savings on your energy bills, further justifying the initial expenditure. Investing in a metal roof is a smart choice for property owners looking to enhance their home's long-term value.


Enhancing Home Aesthetics and Curb Appeal


Metal roofs provide modern aesthetics that can significantly improve your home’s curb appeal. They come in a variety of colors and finishes, allowing you to choose a style that complements your home’s design. This versatility means you can achieve a sleek and stylish look that stands out in your neighborhood.


Additionally, metal roofing’s unique textures and profiles can give your home a distinctive appearance. Whether you prefer a standing seam or metal shingles, there’s an option that can elevate your home’s visual appeal. D&G Exteriors specializes in transforming homes with quality metal roofing solutions, providing craftsmanship and design tailored to your wishes.

Technical Considerations for Installation


When installing a metal roof over composite materials, ensure that you consider critical factors such as local building codes and the potential impact of weather conditions. Understanding these elements will help you achieve a durable and compliant roofing installation.


Adhering to Building Codes


Before beginning installation, check your local building codes. Regulations can dictate how materials are layered, including the use of underlayment and ventilation requirements.


Most areas require a structural evaluation to assure the existing roofing can support the added weight of a metal roof. Additionally, your licensed roofing contractor can guide you in meeting specific local codes. This adherence not only ensures safety but may impact insurance and resale value.


Key points to consider:


  • Verify compatibility with existing roofs

  • Ensure proper drainage guidelines are followed

  • Check any permit requirements

Weather and Environmental Factors


Extreme weather conditions can significantly influence the choice of materials and installation methods. Metal roofs are designed to withstand high winds, heavy rain, and even snow loads, but proper installation is crucial.


Consider factors like:


  • Material type: Ensure the selected metal can handle local environmental conditions.

  • Ventilation: Proper ventilation can reduce heat buildup and humidity, preventing damage.


Installation should also include adequate sealing and insulation to combat any moisture issues that could arise. A well-installed metal roof can provide energy efficiency, reducing environmental impact.


By consulting a professional, you ensure that your installation considers local climate challenges effectively. With expertise in various roofing systems, D&G Exteriors stands out as your reliable contractor.

Metal Roofing Material Options and Styles


When considering a metal roof over your composite shingles, it's essential to understand the various types of materials and styles available. This section will help you explore different metal options, including their durability and unique characteristics.


Different Types of Metal Roofing


Metal roofing comes in various types, each offering distinct benefits. Common options include standing seam panels, which provide an aesthetically pleasing look and excellent weather resistance. These panels feature raised seams that interlock to prevent leaks and facilitate water runoff.


You can also choose from panel styles like corrugated metal, ideal for agricultural buildings, or metal shingles that resemble traditional roofing materials. Each style varies in installation complexity, durability, and appearance. Selecting the right type depends on your home's architecture and your personal preferences.


Choosing Between Aluminum, Steel, and Copper


When selecting metal roofing material, consider aluminum, steel, and copper.

Aluminum is lightweight and resistant to corrosion, making it suitable for coastal areas. It requires minimal maintenance and can last for decades.


Steel offers superior strength at a more affordable price. It’s often coated in zinc for added durability against rust.


Copper is a premium option known for its longevity and natural patina that develops over time. While it's more expensive, its visual appeal can enhance your home's value.
