Chimney flashing installation video on a metal shingles roof

As you can see in the video above, the chimney flashing (as well as skylight flashing) on a metal shingles roof is rather simple, compared to that of standing seam metal roof, which you can see in the photo below.

The chimney flashing photo below shows a standing seam metal roof with a chimney located on the ridge line, which makes the flashing detail much simpler and eliminates the back pan flashing. which is the weakest point of this flashing detail.

Chimney flashing on standing seam metal roof:

The elimination of ribs (vertical snap-lock on standing seam metal roofs) makes the flashing detail using metal shingles for both chimney and skylight, a breeze.

How metal shingles are manufactured

Metal shingles are made in factory settings using a stamping manufacturing process on an industrial size press. A special dye stamps the metal shingle profile, while two additional dyes bend the locks on all four sides of the shingle.

Metal shingles are stamped from a steel, aluminum or copper coils of certain thickness. Steel and aluminum coils are usually painted with 7-layer bake-on Kynar 500 metal roofing paint, which provides the longest lasting discoloration and peel/chip resistance and eliminates the need to paint your metal roof every 5 or so years.

All accessories for a metal shingles roof system are made using either a rolling or bending process on a computerized brake. These are your drip edge, side-wall / head-wall flashing, valley pan, etc. The ridge / hip caps are usually also stamped out of the same coil used to stamp shingles. A 10 foot field-fabricated ridge-cap section can also be used, with exposed of concealed fasteners. Check out this article for more info on how metal roofing is manufactured .

Metal Shingles Roof Installation:

Metal shingles should be installed over a solid sheeting deck such as CDX plywood or OSB board and proper underlayment such as GAF DeckArmor breathable synthetic roof underlayment. Try to stay away from non-breathable underlayments and Ice & Water shield with metal shingles roof, as they trap moisture and may cause roof deck rotting.

If your deck is 16 boards or similar, you may run into problems with installing and nailing metal shingles. If the row of shingles lands on the crack between boards, your nails will not have a solid substrate to be nailed into. Solution in this situation may be using longer clips, that extend past the crack between the boards, or installing a layer of 3/8 plywood or OSB over the boards. Using long clips will however result in weaker fastening and lesser pullout / wind uplift rating for the metal roof. Installing a layer of 3/8 sheeting is a preferred method.

Metal shingles are fastened to the roof deck with nails and either clips or built-in nailing strip on the metal shingle. There are various types of metal shingles and each has its own fastening method, though they are rather similar to each other.

Metal shingles should be nailed to the roof deck, using nails made out of the same metal as the shingle. Thus a steel metal shingle is nailed with regular galvanized roofing nails, and aluminum metal shingles are nailed with aluminum ring-shank nails.

Metal shingles are installed from the bottom, going up. Direction of shingles placement is dependent on the shingle design, but most metal shingles systems are installed from left to right. Each metal shingle is locked into the locks of 6 neighboring shingles, making the whole system very durable and resistant to high-speed winds.

As shown in the video above, an aluminum metal shingles roof is installed over a properly prepared roof deck, and nailed down with aluminum ring-shank nails, through special ears or nailing strip built into the metal shingle. Other systems will have different nailing detail such as clips, or a nailing strip going across the top of the shingle.

Metal Shingles Roofing Materials and Prices:

Metal shingles roofing is usually made from steel or aluminum, and on a rare occasion you will see a copper or zinc metal shingles roof. The reasons for using steel and aluminum are the facts that both metals are very durable and long lasting (assuming the steel is properly galvanized using G-90 or Galvalume coatings). Steel is somewhat cheaper than aluminum, but difference is not very significant, and much of roof installation cost comes form professional installation as well as a rather high cost of metal.

Copper and zinc metal roofs are generally very expensive and therefore not as popular as steel or aluminum roofs. Installation costs for either type of metal roof will vary from one region to another, but in general, metal roofing prices are much higher than asphalt shingles roofs.

As compared to the cost of standing seam metal roofs, metal shingles shingles are considerably less expensive, as they are made from thinner gauge metal, and are easier to install.
