Your local metal roofing contractors take an entirely different approach when it comes to this material. Every roofing material is different, which means every installation is also different.
You wouldn’t hire someone who’s only colored hair to bleach yours for the first time, would you? The same care should be taken with your metal roofing contractors — plus, the cost is a lot higher than anything your salon would charge.
Understanding what’s required for metal roofing installation will encourage you to pay close attention to whom you hire. For example, with metal roofing, it all literally starts at square one. The very first panel must be installed perfectly square, since it dictates how the rest of the panels will fit and look. A reputable metal roofing contractor will have plenty of before-and-after photos, and also be happy to walk you through the steps.
Heavy Metal
It’s not technically required to predrill screw holes, but it’s part of the pre-planning that can help the entire process go more smoothly. If your roofing contractor pre-drills, that’s a sign that the company has patience, good time management and is committed to performing the best job possible. Plus, it makes the job easier (and more accurate) because the screw lines are straighter. Panel stacks of 10 can be pre-drilled at one time, but precise measurements are a must.
Some contractors will pop lines for the screws, which is a perfectly fine way to prep. However, only blue chalk should be used — never red. Red chalk can stain, sticking to the roof for months, and is simply a lazy approach to roof installation. It’s a sign that your roofers aren’t very particular about the finished product and don’t take pride in their work. Sometimes it’s the little things that let you know how dedicated a contractor is.
The Finer Points
Often, panels might need to be cut lengthwise. A clean edge is achieved by slicing numerous times with a box cutter, then bending and snapping. Another option is using tin snips or a special drill attachment. Ensure your metal roofing contractor uses one of these approaches so your panels look clean and professionally cut (because they should be). Fasteners should be screwed in tightly (but not too tight) and straight. This requires the proper drill tension and testing — once again, your roofing contractor should be committed to testing and fine tuning to give you the roof installation you deserve.
Finally, the finishing touches should include the removal of metal shavings and filings — when left behind, they can cause rust. Part of a contractor’s job is to leave your home clean. Now that you know what goes into this kind of installation, it’s time to secure only the best for your project.
