Why do you put screws on the flat versus the rib?
It is highly recommended by the manufacturer to fasten screws on the flat of the metal panels. If the screws are fastened on top of the rib, within 7 years the screws will be loose due to the expansion and contraction that happens within the ribs of the metal panel. Over tightening of screws on the ribs may also occur during installation, causing the metal panels to be off square.
What's the thickness of your steel?
Textured SMP Steel Panels = 26 gauge (before coatings)
Standard SMP Glossy Panels = 28 gauge (before coatings)
What does my warranty cover?
The warranty covers the coating of the panel if it cracks, blisters, flakes, if chalking occurs, fade or change color.
Is there a workmanship warranty?

How does living on the oceanfront affect my warranty?
Panels painted with SMP coatings that are within 1500 ft of the ocean may affect your warranty. If there are aggressive atmospheres such as those contaminated with salt spray, a PVDF coated panel is recommended. PVDF coatings come with a 25 year warranty on the oceanfront.
What's the difference between your textured and standard panels?
Our textured panels are a thicker 26-gauge steel with a heavier, tactile coating. The standard gloss panels are a lighter 28-gauge steel with a reflective, gloss coating.
Do you need to strap a roof for metal installation?
Yes, it is highly recommended. Not only does it make the roof easier to walk on during the installation process, it is also critical to providing proper air flow between the roof underlay and the roofing panels.
Do you recommend installing metal over my existing shingles?
Yes, this removes the need for an additional vapor barrier to be added to the roof. It lowers the installation cost as there are no additional fees for said vapor barrier, as well as removal and dumping fees of old shingles.

Will the metal panels rust on the raw or cut edges?
Not unless an abrasive cutting wheel or saw is used. There is a high zinc content in the metal panels. This inhibits progressive rusting on the edges of the steel, although some discoloration may occur.

What is the difference between galvalume and galvanized?
Galvalume is produced by a hot-dip process with a coating of 55% aluminum, 43.5% zinc, and 1.5% silicon. It is recommended for use in residential applications as well as salt environments.
Galvanized is also a hot-dip process but a 100% zinc coating is used, making it ideal for animal confinement applications.
What are the advantages of your textured metal panels?
The 26 gauge, textured metal panels, are thicker in gauge and are easier to walk on due to their tactile surface. The anti-glare finish provides a modern look and is extremely durable.
What are the advantages of your standard glossy metal panels?
Standard glossy metal panels are a lower price, 28 gauge steel, but are also very durable with more colour options.
Will my wood strapping eventually rot?
If the roof is not properly ventilated, condensation may cause the strapping to rot. Our metal roofs are installed on ¾” strapping with both top and bottom vented foam closures. This ensures proper air flow, drastically decreasing the chances of rot.
Is airflow necessary between the metal panels and roof surface?
Yes, airflow is necessary to avoid condensation.
Do you remove whirly vents?Yes, whirly vents are not required when the roof is properly vented.
How do you flash brick chimneys?
We flash brick chimneys by grinding horizontal ¾” deep slits on each face of the chimney approximately 4”-6” up from the roof slope. Custom trims are then bent on site to ensure a water tight fit.
How do you install flashing around skylights?
Skylight flashings are custom made on site and either cover, or are put underneath the existing skylight flashing. This ensures the best fit possible.
