WHAT DO I USE TO MARK MY METAL PANELS?
DO I NEED A RUBBER UNDERLAYMENT UNDER MY METAL ROOFING PANELS?

A rubber membrane underlayment should always be installed under a valley, or any detail or flashing that is difficult to seal. If you live where it snows and the snow melts during the day and refreezes at night persistently, this causes “ice damming”, and a waterproof underlayment is necessary to protect your underlying sheeting from water intrusion.
HOW DO I PROPERLY LAP MY PANELS?

Exposed fastener panels do take some prior knowledge, understanding, and attention-to-detail in order to lap properly so that you have a properly and evenly installed platform. Do you have a prevailing wind? Make sure the laps face away from the wind. Do you have a low-sloped roof? You may need to install butyl tape. Please consult our installation manual or with one of our customer service agents for further directions as needed.
WHAT TOOLS DO I NEED TO INSTALL MY METAL PANELS?

Installing metal roof and siding can be easily accomplished with standard hand tools: cordless drill, caulk gun, metal snips, tape measure, pliers, chalk line, and applicable safety equipment & clothing such as fall protection, gloves, and eye/hearing protection.
WHERE DO I INSTALL THE SCREWS ON MY PANEL?

Exposed fasteners are normally installed about a quarter inch from the backside of each of the ribs, usually on each purlin, or 24” on-center spacing. At the end of the panel (drip edge or gable end) it is recommended to place a screw on both sides of each rib. All of our exposed fastener panels have screw patterns shown on their respective product sheets. Please contact us if you have any installation questions, or refer to our installation manual.

DO YOU INSTALL METAL PANELS OR PROVIDE REPAIR SERVICES?
DO METAL PANELS SWEAT?

Metal conducts the heat and cold quickly, reaching the dew point faster than most materials. When the difference of the temperatures inside versus outside the building exceeds a certain threshold, and there is no thermal block, the metal panels will often “sweat”, or condensate, in the interior of the building.
DO YOU PROVIDE INSTALLATION MANUALS?
WHAT ARE THE CONDITIONS IN WHICH THE PAINT FILM INTEGRITY MAY BE PREMATURELY COMPROMISED?

Metal panels should not be in continuous contact with the ground, plants, water, etc.; whether siding panels are installed too low, or roofing panels have debris left on them for extended periods of time, the paint needs to be dried by the air periodically or else it will be prematurely damaged. Storage prior to installation is when the metal’s coating is especially susceptible to damage due to excessive moisture accompanied by heat. Please discuss proper storage and handling of your order with your customer service agent.
SHOULD I TEAR OFF MY OLD SHINGLES BEFORE INSTALLING MY METAL PANELS?

It depends on a number of factors. Metal usually weighs only 1/3 as much as composite shingles, thus the added weight usually is not significant. It may be a good option and may save you the time and labor of removing the old shingles, plus the environmental concerns and cost of disposing of asphalt. Keep in mind you will either want to cover the shingles with felt paper or install furring strips (often 1” x 4” wood boards) on top of the shingles, parallel to the eave and ridge at appropriate intervals; this way the metal panels do not scratch against the composite granules. Check with your building department to verify if tearing off shingles is required before installing metal. It is always best to install metal roofing panels over a clean, smooth surface.
SHOULD I ADD INSULATION, OR VAPOR BARRIER, UNDER THE METAL PANELS? IF SO WHAT TYPE?

Is your building heated or cooled? If yes, then investing in insulation under the panel may serve a number of purposes, especially saving energy expenses. Depending on the R-value you wish to attain, and other factors, you may benefit from foil-faced plastic bubble, vinyl-sided fiberglass, or foam insulation. Non-Insulated buildings benefit from a thermal break, resolving condensation issues.
CAN YOU HELP ME DECIDE WHICH METAL PRODUCT WILL BEST SUIT MY NEEDS?
HOW DO I PROPERLY STORE MY PANELS?

The key is to allow the materials to dry periodically. Indoor storage is ideal. Outdoor storage is often accomplished through stacking one end of the panels on more blocks than the other side in order to drain any accumulating moisture. Note that both sides of the panels should be raised off of the ground which otherwise would lead to constant contact with moisture. Avoid covering your metal with plastic, or other air-tight materials, causing moisture to be trapped underneath the tarp (covering your material with canvas, or similar material, is advised).
WHAT COLORS ARE AVAILABLE? DOES IT DEPEND ON THE PANEL?
WHY SHOULD I CHOOSE METAL ROOFING INSTEAD OF ASPHALT SHINGLE ROOFING?

Ever see moss growing on metal roofs? Steel roofing is less than half the weight of shingles and the reflectivity in the paint could very well lower your energy costs. Paint has come a long way in our industry and all of our standard colors have a 40-year limited warranty against chalking, fading, peeling, etc. Not only does our metal have superior life-cycle cost saving, but it is also more resistant to fire, hail and wind damage. When replacing your roof you may be able to fully recycle your roof for cash, versus paying a dump fee to get rid of the old roofing.
