Metal Roofs Are Sustainable

Metal roofs are one of the more sustainable roofing options out there, especially compared to asphalt shingles. When a metal roof reaches its end of service life, it can be recycled and turned into another brand new roof. Metal roofs also help reflect heat and energy from the sun, cutting down on energy costs by as much as 20%.

Metal Roof Shingles And Tiles

Metal shingle- or tile roofing looks quite different than sheet roofing. With these, metal is formed into shapes that imitate Spanish and mission tile, wood shakes, slate, and Victorian metal tiles. Most are made from painted or coated steel or aluminum that has been pressed or formed into realistic shapes.

In addition, metal shingles are typically given multiple-layer factory finishes that complete the realistic effect of mimicking other materials.

In fact, some metal shingle roofing materials are amazingly convincing at imitating the look of other materials. Producers of painted metal products reduce tell-tale sheen by texturing the metal, layering the finish, and applying granulated-stone topcoats.

These products, typically tile or slate lookalikes, can be hard to distinguish from the real thing.

Metal shingle systems are manufactured as panels that have the appearance of several tiles or shingles joined together. They also come as individual shingles. The larger panels, typically about 4 feet long, are designed for quick installation and to bridge across irregularities. Single shingles, meant to be applied one by one, can be easier to handle and more accommodating on irregular or complicated roofs.

Most paneled shingles can be installed over one or two layers of existing roofing. The individual shingles require tearing-off the old roof so the shingles can be applied to a firm, flat roof deck.

Standard Size Of Roofing Sheets

Whenever someone is looking to add metal roofing to their home, they are undoubtedly curious what size sheets metal roofing comes in. Its tough to say the exact size or length of the metal roofing panel because it differs from one panel to another depending on the metal, style, and manufacturers specifications.

Choosing shorter metal panels for your home may leave holes on your roof, which will be prone to leakages. They will not be energy-efficient and will not protect your house from harsh weather conditions.

On the other hand, if you choose metal panels that are too wide or too long, it will cost you more in labor and there will be wastage from some of the panels.

When looking at metal panels on the market, you will notice they come in different gauges like 22, 26, 24, and 29. The length and width also vary from one panel to another. You should know the precise measurements of your roof while purchasing metal panels.

However, the two sides of the roof can be of different measures, so it is important to measure all sides and repeat the calculations. All you will need to do is add the number of panels needed for each side.

Can You Put Steel Roofing Over Asphalt

Can you avoid tearing off your old asphalt shingle roof by putting a steel roof over it? Maybe. Most codes now allow no more than two layers of roofing before requiring a complete tear-off.

How Much Does A Metal Roof Cost

That all depends on the type of roofing materials that you choose and the style of property, along with any other individual details that may make installing a metal roof more or less complicated.

The cost of metal roofing per sq. ft. or the metal roof cost per square or the cost of a metal roof vs. shingles obviously makes a difference, but there are other factors including the aesthetics of your property, the amount of time you plan to spend there before you resell , and the energy efficiency of having a metal roof versus asphalt or wooden shingles.

You should also keep in mind that the total cost of a standing seam metal roof or a metal shingle roof also includes the specialized labor required to install the metal roof as well as the raw materials, and this may be the reason why some homeowners choose shingles over metal roofing.

For some properties, the style of the home and the climate of the area it is located in may mean that asphalt shingles or wood shingles are a superior choice.

That said if you choose metal roofing systems of any kind whether you go with standing seam, copper shingles, zinc shingles, steel shingles, aluminum roofing, or any other kind of metal roofing system, you will likely benefit from their durability and longevity, heating and cooling efficiency, resale value for both the metal roofing materials themselves and your property as a whole, and overall pleasing visual appearance.

Install Metal Panels Or Shingles

Before installing your metal roofing panels or shingles, measure and cut your metal panels to the precise measurement so they are the exact size you need to cover the roofing area. Any improperly cut panels will cause problems during and after your metal roof installation job.

When applying panels to your roof, start from the bottom by the eaves and work your way up. Align each metal shingle so that it overlaps with the edging of the bottom metal panel by ½ to ¾ inches. The new panel placement should align squarely with the previously installed metal roof panel.

Each type of metal roofing sheet has instructions on where and how are apart the screws should be place so read and follow the instructions thoroughly. Be careful not to over tighten the metal roofing screws.

Once the metal roof panel is installed, caulk 100% silicone sealant along the underside of the next panels short edge. When installing the next panel, the short edge of the new panel should overlap the longer edge of the already laid metal roof shingle.

Follow the same steps to install each metal roof shingle as you work your way up the roofs surface.
