Metal roofing has become an increasingly popular option for homeowners in Arlington, TX. Known for its longevity, durability, and energy efficiency, metal roofing stands up well to the area’s hot summers and occasional severe weather. Whether you’re looking to upgrade the aesthetic of your home or improve its energy performance, installing a metal roof can be a wise investment. It also offers superior protection against fire and high winds, which is particularly important in areas prone to storms. However, proper installation is crucial to ensure these benefits. In this guide, we’ll walk you through the essential steps to install metal roofing in Arlington, TX.
2. Preparing for Metal Roof Installation
Permits and Local Regulations in Arlington, TX
Before installing a metal roof, you’ll need to check with Arlington’s local building authority to ensure that you comply with zoning laws and building codes. In many cases, a permit is required for roofing projects, especially when replacing an existing structure. The city may have specific requirements regarding the type of metal roofing allowed, especially in designated neighborhoods or historical areas. It’s essential to have these approvals in place before proceeding.
Tools and Materials You Will Need
To successfully install a metal roof, you’ll need to gather the right tools and materials, including:
- Metal roofing panels
- Measuring tape
- Metal snips or a saw
- Drill and roofing screws
- Roofing underlayment
- Metal flashing and trim
- Chalk line for alignment
- Safety gear (gloves, safety goggles, harness, etc.)
Inspecting the Existing Roof Structure
Before you begin, inspect the current roof structure for any signs of damage or rot. If you’re installing a metal roof over an existing shingle roof, make sure the old roof is in stable condition. Any damaged or weak areas should be repaired beforehand. Additionally, the roof slope should be suitable for metal roofing to ensure water drainage.
3. Step-by-Step Guide to Installing Metal Roofing
Measuring and Calculating the Roofing Material
Before ordering your metal roofing panels, you’ll need to measure your roof to calculate the amount of material required. Use a tape measure to record the dimensions of your roof, including the length and width of each section. Be sure to account for roof overhangs and waste by adding 10-15% to your total material estimate. Accurate measurements are crucial to avoid material shortages or excessive waste.
Preparing the Roof Surface
To install a metal roof properly, you’ll first need to prepare the roof surface:
- Remove old roofing: If you’re not installing the metal panels over existing shingles, remove all old roofing material and inspect the deck for damage.
- Install roofing underlayment: After clearing the surface, lay down a high-quality roofing underlayment. This helps protect your roof deck from moisture and adds an extra layer of insulation.
- Install the edging: Attach drip edges to the roof’s perimeter to guide water away from the roof and prevent leaks.
Installing the Metal Panels
- Laying the panels: Start at the bottom edge of the roof and work your way up. Begin by positioning the first panel along the roof’s eave. Ensure it’s square to the edge of the roof and extend the panel slightly over the eave to allow for water runoff.
- Securing the panels: Use roofing screws with rubber washers to secure the panel in place. Insert screws into the flat areas of the metal panel, spacing them about every 12 to 18 inches. Ensure each panel overlaps the adjacent one to create a watertight seal.
- Aligning the panels: Use a chalk line to keep the rows straight and ensure the panels are uniformly aligned. This will help maintain an even appearance and prevent gaps or misalignments.
Adding the Trim and Flashing
Once all the panels are in place, it’s time to install metal trim and flashing:
- Ridge cap: Attach a metal ridge cap to cover the joint where two roof sections meet at the peak. This will protect against water intrusion.
- Valley flashing: For roofs with valleys (intersections where two roof planes meet), install valley flashing to direct water flow and prevent leaks.
- Sidewall and endwall flashing: Install flashing along any walls that intersect with the roof to provide extra protection from water infiltration.
With the panels and trim in place, the bulk of the installation is complete. All that’s left is to ensure your roof is sealed properly.
4. Considerations for Arlington’s Climate
Heat and Energy Efficiency
Summers in Arlington can be extremely hot, with temperatures often exceeding 90°F. Metal roofs are ideal for this climate because they reflect solar heat more efficiently than traditional asphalt shingles, helping to keep homes cooler and reducing energy consumption. When choosing a metal roof, consider installing reflective coatings or selecting a lighter color to enhance this reflective capability. This will further increase the energy efficiency of your roof and help reduce cooling costs during the summer months.
Storm and Hail Resilience
Severe weather, including thunderstorms, high winds, and occasional hail, can be a concern for Arlington homeowners. Metal roofing is well-known for its durability and ability to withstand high winds and impact. Be sure to choose a metal roof with a high wind rating (at least 120 mph) and one that is rated for hail resistance. Steel panels with a thicker gauge (lower number) can offer better resistance to hail damage. Additionally, ensure that the fasteners and screws are securely tightened to prevent wind uplift.
Choosing the Right Material and Coating
For the Arlington climate, steel is often the preferred choice due to its strength and affordability. Opt for galvanized or galvalume steel, which has a protective zinc or aluminum coating to prevent rust and corrosion in humid or stormy conditions. In addition, consider using a high-quality paint or coating that includes UV protection and anti-corrosion properties to ensure that your roof can withstand years of exposure to sun and rain.
5. Final Inspections and Maintenance Tips
Final Inspection
- Check the fasteners: Ensure that all roofing screws and fasteners are tightly secured. Loose screws can lead to leaks and wind damage. Re-check the rubber washers to ensure they’re correctly positioned to seal the screw holes.
- Inspect the flashing: Verify that all flashing, especially around chimneys, vents, and valleys, is securely fastened and properly sealed. These areas are often prone to leaks, so proper installation is critical.
- Examine panel alignment: Look over the roof to make sure the metal panels are properly aligned and overlapping as needed. Misalignment could result in gaps that allow water or wind to penetrate the roof.
- Waterproofing test: If possible, perform a water test by using a garden hose to simulate rain. Spray water across the roof to check for any potential leaks, particularly around seams and flashing.
Long-Term Maintenance Tips
- Regular inspections: Perform roof inspections at least once a year, especially after major storms. Check for any loose screws, signs of rust, or damage to the panels or flashing.
- Clean the roof surface: Keep your roof free of debris such as leaves, branches, and dirt. Accumulated debris can trap moisture, which can lead to rusting or other damage.
- Gutter maintenance: Ensure your gutters are clean and functioning properly. Clogged gutters can lead to water buildup around the edges of the roof, causing leaks or damage.
- Address minor issues early: If you notice any signs of rust, loose screws, or damaged flashing, address these issues immediately to prevent them from becoming larger problems.
6. Conclusion
Installing a metal roof in Arlington, TX, can be a wise investment that offers long-term benefits such as durability, energy efficiency, and protection from severe weather. By following the steps outlined in this guide and considering the local climate, you can successfully install a metal roof that will stand the test of time. Always remember to check local building codes and permits, and when in doubt, consult a roofing professional to ensure the job is done right.
