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.
Textured SMP Steel Panels = 26 gauge (before coatings) Standard SMP Glossy Panels = 28 gauge (before coatings)
The warranty covers the coating of the panel if it cracks, blisters, flakes, if chalking occurs, fade or change color.
Yes, Walls has a workmanship warranty of 5 years after the installation date.
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.
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.
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.
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.
No. Our standard screws come with a covered EPDM rubber washer with no additional warranty. We do however offer Sealtight screws that have a 40 year warranty.
We offer fascia cladding to our customers. Installation is done through subcontractors.
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.
It is not recommended. The heat from the cutting wheel may cause the panel to rust.
Yes.
No, not unless the panels are defective, contaminated with salt spray, or exposed to chemical fumes.
Yes, a deposit is required. Once received, your order is then added to our schedule.
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.
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.
Standard glossy metal panels are a lower price, 28 gauge steel, but are also very durable with more colour options.
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.
Yes, airflow is necessary to avoid condensation.
Yes, whirly vents are not required when the roof is properly vented.
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.
Skylight flashings are custom made on site and either cover, or are put underneath the existing skylight flashing. This ensures the best fit possible.
Yes, depending on the pitch and whether or not snow stops are installed.
No, our metal roofs are rated for up to 300 KM/HR winds
If the roof is insulated properly then the sound of rain on the roof should be almost 100% inaudible.
Our metal roofs reduce heat by allowing hot air to escape through the ridge ventilation.
Walking on your metal roof with clean shoes should not damage the steel. Take extreme caution when doing so and ensure proper safety precautions are in place.
No, a metal roof will not make lightning more likely to strike, but it may make a lightning strike less dangerous if it occurs.
Yes

We now produce a number of siding profiles that are installed by subcontractors.
At this time we only supply and install exposed fastener roofing systems.
Yes
We are currently expanding our facility to allow for panel roll forming. Our trims and roof accessories are all manufactured at our facility.
