Its easy to install. Just snap it onto the previous panel, and screw along the integral fastener flange. Nailing or screwing is allowed, but using wafer head screws is the best way to install this panel. After applying sufficient screws along the flange for proper wind uplift protection in you area, you're ready to snap on another panel. Its just that easy !

 Coverage = 11.75" Nominal Width ... 0.98 ft

Lengths = 28" long to 28 Lin Ft Long.

Longer panels can be made with a nominal up-charge, plus special crating charge. Normal length panels if palletized have a smaller pallet charge, depending on lengths ordered.

If we produce Weather-Lock panels longer than 28 feet,handling and transportation become issues you or the installer may face. Also lengths above 28 feet are more likely to face oil canning distortion risk, and therefore we recommend our Snap n Lock 1" with separate clips for those longer panels. Snap-Lock 1" can be joined to the male or female ends of Weather-Lock if your project only requires a few longer clipped panels, but the Snap n Lock panels will cover 13" width instead of 11.75".

The Weather-Lock 1" high panel creates nice shadow lines vertically every 12" (approx). For better appearance we recommend 26 gauge or preferably 24 gauge. If you prefer more definition we also make this panel as a 1.5" high version.

The colour palette that is available is remarkable.

Check out the following website ...

Certain colours come in specific gauges only, or sometimes in 24 gauge Kynar 500 finish Galvalume only. Call our office for additional information, and colour availability.

Kynar 500 finish has better resistance to colour and panel fade than regular baked enamel paint. It also comes in unique colours such as Copper Penny, Weathered Zinc, and Silver Metallic which also metallic finishes. Some of nicest roofs are completed in these colours, and the homeowners can expect these paint finishes to last better and look better longer.

When ordering this panel calculate the width of roof required to cover, and what length each section requires. Divide the width of each section by 0.98 ft and you'll have the required amount of panels to order in the length of this section. We can keep the panels together for each section, and label them if you wish.

For example, if you need to cover 30 lineal feet wide of roof with 17'3" long panels, please divide 30/.975. The answer is 30.77 panels ...so order 31 panels @ 17'3" long. This section of roof will take 535 lineal panel feet of roof to cover the area.

If you want to get fancy, we could make 30 panels @ 17'3" long, and make you a final panel @ 8" wide. The rib reinforcing will have to eliminated or reduced to a single rib for this last panel if you want it pre-made in this narrower version panel. The reason the panel is created 8" wide instead of 9" wide (11.7x.77) is to allow for the final fastener flange width. We cannot form panels narrower than 8" in lengths over 10 feet long.

We suggest that for each section of roof you consider ordering one additional panel. Mistakes happen on site, and the small investment in a few extra panels can pay off, rather than waiting for more coil to be slit and roll-formed into additional panels.

For valleys and hips calculate the width to cover on each side of the valley or hip and what sizes the panels need to start and stop at for length. Order slightly larger as small cut off waste is better than panels that are too short. Remember that the shortest panels we can cut is 24" long (or 35" long for "pre-notched" panels.

For valleys and hips you can continue ordering the same length as the panels entering the hip or valley. Simply calculate 65% of the roof width through the valley or hip area as the extra panels required to complete this area. The off-cuts will eventually become long enough to complete the remaining 35% of the roof width. Often roofers will use the off-cuts for the opposite side of a valley or hip, as the bottoms will then still be cut square.

For skylights and chimneys, order the field panels 4 foot longer for each chimney or skylight, and two additional panels width beyond the skylight width. For example, if you have one 2ft wide by 4ft long skylight in the roof, order 4 panels at 4feet longer than the panels in this section of the roof. If you have 3 such skylights than order 12 panels at the 4 foot longer measurement. This will give you the material needed to cut the panels 12" past the top of the skylight, install the back-pans and flashings, and then install the panels overlapping the previous lower units (using good roofing and flashing techniques, sealants, and water-diversion methods). Contact our office for further information.

Allow for metal roofing to drip off the roof about 1.5" minimum where possible. Also we recommend a metal drip edge with built-on 1" or 1.5" overhang to support the bottom edge and increase wind resistance against uplift.

For better roofing practice the applicator can fold the edge of the panel around this eave edge detail if the panels are ordered long enough.

WE NOW HAVE AVAILABLE "Pre-Notched" panel service. For about $1.50 per panel extra, we can notch off the ribs on the top and bottom 1" of the panel. This will provide a panel that can be folded over the drip edge as well as can be folded up at the top of the panel.

To vent the attics of metal Snap-Lock type panels, ridge venting is a popular method. Check with us for specific instructions. The general idea is to leave the plywood or strapping back 1.5" from each side of the ridge and install a "J-Metal" or "Z" metal to support a Trimline Rigid Vent Plus 11" Ridge Vent, and to provide an attachment support for the fasteners when installing the Ridge Cap Flashing above the ridge vent. Always make sure you allow for the right length of panel to achieve the ridge venting solution, as well as providing the right drip detail.

We do not recommend the drip edge detail to be flush with the panel as staining and discoloration of the drip edge flashing and fascia will likely occur in our climate region. Remember, all the water and rainfall is evacuating off the roof at this point, and it is important to have good detailing in this area of the roof. Our "T" shaped metal drip edge is a good start.

Normally we will palletize or crate the panels,  for a nominal fee (depends on panel length). For long distance transport we recommend crating, but this will be a higher per pallet fee than our simpler pallets (depending on length).

The Snap-Lock panels can be installed over spaced strapping or a solid deck, but we prefer to see solid decks. A solid deck will allow greater walk-ability in the long run, it will provide better support and show less distortion of the finished roof, and it clearly provides a better waterproofing of the roof system. A solid deck supports the underlayment better, supports foot traffic better, and is our recommended solution.

In all cases the metal roofing should be installed over an underlayment as a minimum for condensation protection.

When ordering Weather-Lock panels below 28feet in length, we can make special "male-male" starter panels. These provide a nail flange on each side of the panel so one can start in the middle of a roof and work in either direction. A good place to use this is beside a dormer in the middle of the roof (only one can be used per roof section), or even better use is one can square up and start a panel at the top of a hip section. This means the main field of a roof can be completed in one direction, while the cutting of panels down the hip area can proceed later. Also it eliminates the need to start with the shortest panel which can be hard to start "square", and it also allows you to use up waste later on these shorter panels.

A typical male-male starter panel will cost about $25 extra fabrication fee per starter panel, but it can save time and effort.
