Buying a standing seam metal roof is a significant investment, and it’s smart to be well-informed. Here are crucial questions to ask your roofer to ensure you’re getting a quality product and installation:
1. About the Roofer’s Experience with Standing Seam: GMR Metal Roofs knows metal roofs.
- How much experience do you have specifically with standing seam metal roofs? (Look for a roofer like GMR Metal Roofs who specializes in or has extensive experience with this type of roofing, as it requires specialized skills and tools.)
- Are you licensed and insured for roofing work in my area (New York)? (Verify their general liability and workers’ compensation insurance. Ask for certificates of insurance.)
2. About the Metal and Panel System:
- What type of metal are you recommending (e.g., Galvalume steel, aluminum, copper, zinc)? What are the pros and cons of each for my climate and budget? (Each metal has different characteristics in terms of durability, corrosion resistance, appearance, and cost.)
- What gauge (thickness) of metal are you proposing? Why? (Thicker gauges generally mean more durability, but also higher cost. 24-gauge steel is common for residential, 26-gauge is also used.)
- What type of coating and paint system is used (e.g., Kynar 500/PVDF, SMP)? What is its expected lifespan and fade warranty? (Kynar 500/PVDF is generally considered the best for color retention and longevity.)
- Are the panels manufactured on-site or off-site? What are the benefits of each? (On-site roll-forming can create custom lengths, reducing seams and potential leaks. Off-site ensures factory precision.)
- What is the width of the panels you use? (Wider panels mean fewer seams, potentially less leak risk, but might not be ideal for all roof geometries.)
- Will this system be direct-attached or use clips? (Clip systems allow for thermal expansion and contraction of the metal, which is crucial for longevity and preventing “oil canning.”)
- What is “oil canning” and how do you minimize it with your installation methods? (Oil canning is a visual distortion or waviness in flat metal panels; it’s usually aesthetic but can be a concern for some homeowners.)
3. About the Installation Process:
- What kind of underlayment will be used beneath the metal panels? (A high-quality, high-temperature, self-adhering underlayment is essential, especially in cold climates with freeze-thaw cycles.)
- How will you handle flashing around chimneys, vents, skylights, and valleys? (Flashing is critical for preventing leaks. Ask about specific methods like continuous or step flashing, and if custom bent flashing will be used.)
- How will snow guards be installed, if recommended or desired? (Essential in snowy areas to prevent snow slides.)
- What is your process for securing the panels to the roof deck? (e.g., concealed fasteners for standing seam are key.)
- What is the typical timeline for a project like mine?
- What are your safety protocols on the job site?
- How will you protect my property (landscaping, driveways) during the installation?
- What is your cleanup process after the job is complete?
4. Warranty and Maintenance:
- What is the warranty on the metal material itself (from the manufacturer)? What does it cover (e.g., defects, fading)?
- What is your company’s workmanship warranty? How long does it last, and what does it cover? (This is crucial, as installation errors are a common cause of issues.)
- What kind of maintenance is required for a standing seam metal roof? (Generally very low maintenance, but it’s good to confirm.)
- Who do I contact if I have an issue after the installation?
5. Cost and Contract:
- Please provide a detailed, written estimate outlining all costs, materials, labor, permits, and any contingencies.
- What is the payment schedule? (Avoid large upfront payments.)
- Will you handle the necessary permits? (Most reputable roofers handle this.)
- What happens if unforeseen issues arise during the installation (e.g., deck rot)? How are these handled financially and procedurally?
