FAQ
Got questions? We've got answers.
Straight answers from the people who roll the panels.
What are the advantages of metal over shingles?+
Prefinished metal comes in a broad palette of colors with long-life coatings that resist moss, mildew and fungus. Panels are lightweight yet strong enough to shed severe weather, they're non-combustible, they last decades longer than asphalt, and they require virtually no maintenance.
Can I install metal directly over my old shingles?+
Often, yes. Metal weighs about a third of shingles, so you can frequently avoid a tear-off. The best method is 1x4 or 2x4 furring strips at 24" on center parallel to the eave and ridge. Check your local codes — some jurisdictions require a tear-off.
How long will a metal roof last?+
This may well be the last roof you put on your home, barn or shop. Lifespans easily exceed 30 to 40 years thanks to corrosion-resistant substrates and durable finishes.
Is metal roofing noisy in the rain?+
No noisier than any other roof. Panels are installed over underlayment and decking, with insulation and ceiling below — all of which mute sound.
How fast can you have my panels ready?+
Standard roofing orders are typically ready in 24 hours. More involved orders with gutters, downspouts and custom trim run 48 to 72 hours. We roll it here, so the schedule is ours to keep.
What warranty comes with the panels?+
40 years on painted panels finished with the Sherwin-Williams Weather XL coating system, and 25 years on Galvalume. Our coil is painted domestically — not overseas — which is a big part of why the finish holds up.
Can you match a discontinued panel on an old roof?+
Usually, yes. We can custom-manufacture a transition panel in-house that ties an obsolete profile into a current one — which often saves a full re-roof.
What gauge should I choose — 26 or 29?+
29 gauge is the value option and is common on agricultural and utility buildings. 26 gauge is thicker, more impact and oil-canning resistant, and is what we recommend for homes and anything you want to look sharp for decades.
How do I attach the panels?+
Use our color-matched screws only. Screws go in the flat of the panel. Fasteners are typically spaced 24" on center.
Do I need an underlayment?+
A rubber membrane underlayment is always a good idea as a second barrier against water. Use it in valleys, at any hard-to-seal detail, on low slopes, and when panels aren't sealed at the side laps.
Can I mark panels with a pencil?+
No. Graphite accelerates corrosion where it touches the coating. Use masking tape and mark the tape instead.
