Got a Question?
If you have a question, there’s a good possibility that quite a few others have already asked the same question. If you don’t see you answer listed, feel free to ask us directly.
- Can I install metal panels directly over my old, worn-out shingles?
Since metal weights only 1/3 as much as shingles, you can often attach metal panels without tearing off your existing shingle roof. This eliminates the costs and problems of disposing of the old shingles. The best way to do this is to attach 1" x 4" or 2" x 4" furring strips at 23" o/c parallel to the eave and ridge. Check local codes to determine if tearing off shingles is required in your area.
- How do I attach metal panels?
You may use either screws or nails-both color matched to the color of your roof. Screw fasteners are preferred over nails for superior pullout resistance and weather tightness. Screw fasteners are designed to go into the flat part of the panel. Nails MUST GO in the high rib of the panel. Fasteners are typically spaced 24" o/c.
- Can I add insulation under the metal panels?
Yes. Among the types of insulation that can be used are fan-fold foam insulation or foil-faced plastic bubble insulation. You can save utility costs by making your roof more energy efficient.
- How long will a metal roof last?
This could very well be the last roof you will ever put on your home, bar, shed or hobby shop-with life expectancies that can easily exceed 30 years. Corrosion resistant substrates and long-life finishes ensure long-term performance, minimal maintenance and life-cycle cost savings.
- Are any special tools required?
Metal roofing and siding can be easily installed using standard hand tools such as a screw gun, hammer, metal snips, caulk gun, pliers, chalk line and tape measure. Cutting metal panels is best accomplished with an electric metal shear; however, panels may be easily cut with a circular saw with a metal-cutting abrasive blade. Standing seam roof systems require hand or mechanical seaming tools.
- Will a metal roof make my house or building more susceptible to a lightning strike?
No. A metal roof will not make a building more susceptible to a lightning strike. Lightning will tend to strike the highest object in a given area regardless of what that object is made of. A metal roof can actually be beneficial in the event of a lightning strike due to being a noncombustible material.
- Can I use a lead pencil to mark on my metal panels?
No. Standard lead pencils, or those made with graphite, will accelerate the corrosion of the metal near the mark. you can use masking tape and mark on the tape to prevent corrosion. Plus, masking tape is easier to see.
