The History Of The Metal Roof
Metal roofs have been around for centuries now. They have been found dating as far back as the 3rd century BC. We have some metal roofs around today that were made back in the 1800s, that still stand as a living testament of their long-lasting durability. Metal roofs have been known to last up to a hundred years or more, which is why you will find some installers giving warranties on them for up to 50 years.
Metal roofs are near impermeable, and they are known to be resistant to all types of dangerous elements such as fire, heavy snow, hail storms, and even hurricanes. Theyre also resistant to corrosion, shrinkage, and cracks, oh so they are superior to shingles in many aspects. Metal roofs are also cheaper than asphalt shingles.
Metal roofs can also give you enhanced energy efficiency due to their high solar reflectance, providing reductions in heat gain because it reflects lighter rather than absorbing it. This offers an ongoing savings on energy costs, and thats something you definitely want to add in if you are considering buying one.

How To Measure Roof Rise
Typical vinyl siding has 4 exposure, so 3 spans would be equal to 12 or 1 foot. Calculate the number of spans from the base line to the peak. Since most homes have a Rake wood, which is usually 6-8 wide, you can add that width to the rise.
Example: If you have 19 spans of siding at 4 exposure of each span, and a 6 rake board, the rise would be:
/ 3 = 6 10 roof rise.

Metal Roof Prices By Type
It is important to understand that metal roofing is a broad term covering a range of materials with a large disparity in price. Metal roofing will generally run you anywhere from $3.10 to $29.65 per square foot, depending on which kind of metal roof you choose to install.
There are more affordable metal roofing options, like steel panels, which usually cost you slightly less, as well as high-end materials, like copper roofing, which tend to average out on the pricier side. Note that new metal roof replacement costs could reach up to $88,000 or more to install on a standard-sized 3,000 square foot roof.

Minimum Slope For Asphalt Shingles
The requirements for an asphalt shingles roof are contained in the International Building Code. According to this code, the minimum slope for asphalt shingles is 17 degrees or two vertical units to twelve units in the horizontal.
In case a slope greater than this is necessary, then a double underlayment application must be used as per the requirements of the International Building Code.
Pros And Cons Of Tin Roofs
Metal roofing is a far greater investment than an asphalt roof. Homeowners should consider the fact that the life of a tin roof is decades longer than other roofing material types and that it can add value to your home. A metal roof can be an affordable option if you want to install a cheaper metal roof material.
Before investing in a new metal roof, you may have concerns about the potential for rust, noise from rain and wind, and denting, but modern engineering addresses these concerns.
You do have to properly insulate your attic to prevent your roof from creating too much noise, but this is sound advice regardless of the type of roof you choose to install. Additionally, with most textured roofs, minor denting if it occurs is not easily visible. Finally, some believe that metal roofing will increase your likelihood of a lightning strike. While metal does conduct electricity, electricity is not drawn to it. In fact, because metal roofing is fire resistant if your home is struck by lightning, your risk of fire is actually

How To Calculate A Corrugated Metal Roof
Corrugated metal roofing is used through out the world, from Alaska to Australia to India. Its appeal owes much to the simplicity and strength of the material, as well as its availability and low cost. Corrugated metal sheeting is available in different thicknesses, styles and sizes, but regardless of the shape and size, the sheets must be overlapped, like roofing tiles, to provide a continuous and watertight finish, with no gaps through which weather can penetrate. The overlap must be taken into account when determining how many sheets to use.
Things To Consider With Metal Roofs
If you are unfamiliar with metal roofs, you may have concerns about the potential for rust, noise from rain and wind, and denting, but rest assured that modern engineering addresses these concerns. Additionally, some believe that metal roofing will increase your likelihood of a lightning strike.
While metal does conduct electricity, electricity is not drawn to it. In fact, because it is fire resistant, if your home is struck by lightening, your risk of fire is actually with a metal roof. Finally, a metal roof will not make your home colder in the winter. As long as your attic is properly insulated, your home will stay just as toasty as any other home in the winter.

Minimum Pitch For Corrugated Metal Roof
Just like other metal roofs, the minimum pitch for a corrugated metal roof largely depends on the profile of the roof.
In most occasions, a pitch of three in twelve is preferred, but this should also take into consideration the manufacturers recommendations as well the unique condition of the corrugated metal roof. These slope considerations also apply to standing seam metal roofs.
The main aim of having a drain or drainage is to redirect runoff away from the roof to other designated places. Water will flow as long as the drainage angle is greater than zero however, not just any pitch above zero is suitable for all kinds of drainage.
It can be argued that the minimum roof slope for drainage is 10 since this is sufficient to allow water to flow, but there are other design considerations that must be taken into account when determining the final minimum slope.
These considerations include the length of the roof, the roofing material, the size of the roof as well as the rainfall characteristics of the region in question.
A wide roof with a steep slope will lead to faster runoff, hence necessitating a slightly steeper slope for effective discharge of the rain water.
A small roof with a shorter length on the other hand will not collect a lot of water within a short period of time and will work just fine with the minimum roof slope for drainage.
How Does The Gauge Of The Steel Affect The Corrugated Roofing Cost
There are lots of options when you are choosing the gauge or thickness of corrugated metal roofing. The gauge of the steel can be a bit confusing as a lower gauge is actually heavier steel. For example, 24 gauge is heavier than 26 gauge steel.
The vast majority of corrugated roofing is either 24 gauge or 26 gauge. Either gauge is appropriate for a corrugated roof. However, if you want a PVDF paint system then you must purchase a 24 gauge. If you would like a 26 gauge roof then it would only be available in a SMP paint finish. Corrugated roofing in a 24 gauge vs 26 gauge will add 25% to 35% to the price.
The lightest gauge that you can purchase is a 29 gauge corrugated roof. It is our opinion that 29 gauge is a bad investment. The 10% material savings vs the overall installed price of the roof just does not justify the lighter gauge.

Standing Seam Metal Roof Costs
Standing seam metal roofs have far superior longevity and last two or three times longer than non-metal roofs. They are the most common metal roof design due to its availability all over the U.S. to roofing installers and easy access to metal materials. The design features vertical panels that are joined by interlocking seams as seen below.
Importance Of A Roof Pitch
The chief reason for having a roof pitch is to redirect water and snow away from the roof and avoid any percolation that might result from stagnation of water on the roof.
As standard practice, places with heavy rainfall or snow storms will have higher roof pitches compared to places that experience less rain and snow.
Other than directing away water and snow, there are still a number of reasons as to why the pitch is such an important component and should never be ignored in the design and installation of any roof type.
It will dictate a number of other roof features such as the roofing material to be used, the architectural properties of the roof, the walkability on the roof and the roof sections to be covered. The pitch also affects the economic aspects of the installation.
For instance, steep pitches lead to more roofing material being used. In turn, this will result in a higher roof installation cost.
