Installation Process Analysis

When you decide to get a new roof, understanding the installation process can help you prepare for what's to come. Both metal roofs vs. shingles and asphalt shingle roofs have distinct steps in their installation processes that are important to know.

Preparing for a New Roof

Before a roofing contractor begins installation, they must remove your old roof. The process involves peeling off old shingles or metal panels and stripping the roof to the decking. When comparing metal roofs vs. shingles, you can expect a thorough inspection of the existing roof structure to identify any damage or areas that need repair. Accurate measurements of your roof will be taken, typically in square feet, to ensure that the correct amount of materials is ordered.

Steps in Metal Roof Installation

  1. Roof Decking Preparation: Your roofing contractor ensures the roof decking is sound and secure. Any necessary repairs or replacements are made at this stage.
  2. Underlayment Installation: A water-resistant or waterproof underlayment is laid over the decking, which acts as an additional barrier against the elements.
  3. Metal Panel Cutting and Shaping: Each panel is cut to the exact size needed for your roof's dimensions.
  4. Panel Attachment: Starting from the edge, metal panels are secured to the roof using screws or clips, overlapping each piece to create a watertight seal.

Asphalt Shingle Roof Installation Stages

  1. Deck Preparation: Just like with metal roofing, the decking must be inspected and prepared, which can include laying down a layer of felt paper.
  2. Shingle Placement: Shingles are laid from the bottom edge of the roof upward, with each row overlapping the last to shed water effectively.
  3. Flashing and Sealing: Different types of flashing are applied around roof features, and seals are created to prevent water penetration.

Remember, whether you choose metal panels or asphalt shingles, the installation process is critical to the overall longevity and performance of your new roof.

  • Heat Absorption: The additional heat absorbed by shingle roofs can slightly decrease the efficiency of solar panels as they operate best in cooler conditions.

By understanding these aspects, you can make an informed decision for your roof that aligns with your environmental values and energy efficiency goals.

Weather Resistance and Structural Considerations

When deciding between metal roofing and asphalt shingles, consider how each option, metal roofs vs. shingles, responds to various weather conditions. It's important to assess their adaptability and resilience to ensure the longevity of your roof.

Metal Roofs in Harsh Climates

Metal roofs excel in environments where harsh weather is a common occurrence. Their durability makes them an outstanding choice for areas prone to high winds and heavy rain. Specifically, metal roofing can withstand wind gusts that often exceed 140 miles per hour. Moreover, metal roofs are adept at shedding snow and sleet, which is particularly beneficial in regions with cold temperatures. Their interlocking panels also add an extra layer of wind resistance, minimizing the chances of uplift during storms.

Asphalt Shingles in Variable Weather

Asphalt shingles are used widely due to their ability to handle a range of weather conditions. However, they may not always fare as well under extreme scenarios. When exposed to harsh weather conditions like severe storms or high winds, asphalt shingles can become loose or even tear off. Their performance in cold temperatures can be a concern too, as they can become brittle and more susceptible to damage. For optimal performance, regular maintenance is necessary to ensure that any damaged shingles are quickly replaced to prevent leaks and other weather-related issues.
