Metal Roofing

Metal roofing is a highly durable and long-lasting option for Philippine houses, made from materials such as Galvanized Iron (GI), Aluminum, or Color-Coated Steel. There are several types of metal roofing, including Ribbed or Corrugated Metal Roofing, Standing Seam Metal Roofing, Tile Effect Metal Roofing, Stone-Coated Metal Roofing, and Shingle Effect Metal Roofing. Architects can choose from a wide range of metal roofing types to match the design and style of the house.

Metal roofing can be customized to match the shape, color, and design of the house, whether it be a traditional or contemporary look. It is relatively lightweight, making it easy to install, and reduces the overall weight of the house. Stone-coated metal roofing is also becoming popular due to its aesthetics.

The reflective properties of metal roofing can also significantly reduce the amount of heat absorbed by a building, reducing energy costs for cooling. Metal roofing is also environmentally friendly as it can be recycled at the end of its lifespan.

In conclusion, metal roofing is an optimal choice as it is a durable, energy-efficient, versatile, and environmentally responsible roofing solution.

While metal roofing has its advantages, it is important to consider the disadvantages before making a decision:

1. Noise: Metal roofing can be noisy during heavy rain, which can be disruptive to building occupants. This can be mitigated by installing soundproof insulation.
2. Installation Difficulty: Installing metal roofing requires specialized skills and equipment. It is essential to hire a reputable and experienced contractor to ensure proper installation.
3. Expansion and Contractions: Metal roofing can expand and contract with intense changes in temperature, potentially causing leaks. This can be prevented with proper flashing and sealing.
4. Design: While metal roofing can be customized to match the design of the house, it may not be the best choice for traditional or historic homes, as the modern, industrial look of metal roofing may clash with the traditional architectural style of the house and its surrounding area.
5. Strong Winds: Being a lightweight roofing solution, it is important to properly secure the metal roof with good fasteners to prevent uplift due to typhoons and strong winds.

In conclusion, while metal roofing has many benefits, it also has its share of challenges. Architects should consider these factors when choosing a roofing material for their projects. With proper planning and installation, metal roofing could still provide a durable, weather-resistant, and cost-effective roofing solution.

The Philippine architecture industry is widely known for its colorful and tropical designs that are influenced by Spanish and American styles. With this, metal roofing has been used in the Philippines for decades due to its design versatility.

The different types of metal roofing are differentiated based on their material, profile, and finish. Some of the most commonly used metal roofing types in the Philippines include:

• Ribbed or Corrugated Metal Roofing
• Standing Seam Metal Roofing
• Stone-Coated Metal Roofing

Also in the Philippines, metal roofing panels are commonly made of steel coated with zinc and aluminum. The shape of metal roofing can also vary, with options like ribbed, flat, or curved profiles. Color-coated metal roofing is a popular option, as it allows architects to choose from a wide range of colors including classic shades of black, brown, and grey, as well as more vibrant hues like red, blue, and green.

Step 1: Choose the Right Metal Roofing Type: Decide on the type of metal roofing that best suits the project’s design and budget. Types include corrugated, rib-profile, tile-profile, and others.

Step 2: Measure the Roof: Measure the roof’s surface area accurately to determine the required amount of metal roofing material.

Step 3: Check Regulations: Ensure the installation complies with local building codes and regulations, including necessary permits and roof structure weight-bearing capacity.

Step 4: Prepare the Roof: Clean the roof surface and remove any existing roofing materials.

Step 5: Install the Metal Roofing: Install a layer of underlayment for moisture protection and attach the metal roofing panels using screws, nails, or adhesive.

Step 6: Seal the Roof: Seal seams and around penetrations (vents, skylights) to make the roof weathertight.

Step 7: Check for Leaks: Check the roof after a rainstorm or simulate rain to identify any leaks.

Metal roofing is a popular choice in the Philippines for its durability. However, proper maintenance is crucial to ensure the longevity and performance of the roof. 

1. Regular Inspections: Inspect the roof regularly, at least twice a year, to identify and fix any potential issues, such as loose screws, cracks, and corrosion.
2. Cleaning: Clean the roof regularly to remove debris, leaves, and moss. Use a soft brush and mild soap to avoid damaging the metal.
3. Sealing Leaks: Seal any leaks immediately to prevent further damage and deterioration.
4. Paint and Coating: Repaint or reapply coating as necessary to maintain the roof’s appearance and protect it from the elements.
5. Avoid Walking on the Roof: Follow the truss as a guide while walking on the roof to prevent dents and scratches.
6. Choose the Right Materials: Use proper roofing materials and products recommended by the manufacturer for maintenance, repair, and replacement.

In conclusion, regular and proper maintenance can ensure the longevity and performance of metal roofing in the Philippines. Following these tips and working with a qualified contractor can help keep their metal roofs in top condition for years to come.

When it comes to pricing metal roof installations, there are several factors to consider:

1. The type of metal roofing. For example, standing seam metal roofing is generally more expensive than corrugated metal roofing.
2. The complexity of the roof, including the number of angles, valleys, and dormers.
3. The quality of the materials used, including the thickness / gauge of the metal.
4. The location of the property and the ease of access for the roofing crew who will install the roof.
5. The installation method, wherein custom installations being more expensive than standard installations.

It is important to keep in mind that these are just general factors, and actual costs may vary depending on the specific project.

Q: What are the benefits of using metal roofing? 

A: Metal roofing offers durability, longevity, and low maintenance.

Q: How much does a metal roof weigh? 

A: Metal roofing weighs less than other roofing materials like concrete or clay, making it a lighter option for structures.

Q: What are the standard measurements for metal roofing panels? 

A: Standard metal roofing panels typically come in 26, 25, 24 gauge and with widths of 0.8 -1.0 meters. Keep in mind that the lower the gauge number, the thicker and stronger the metal panel.

Q: Can metal roofing be used for roofs with a low pitch? 

A: Yes, some metal roofing systems can be used for roofs with low pitch, but it is recommended to consult with a roofing professional for specific requirements and design considerations.
