Failing To Adequately Overlap The Panels
Metal roof panels are designed to overlap with one another, helping you keep water from leaking where two panels meet. The amount of overlap that is required generally depends on the overall slope of your roof.
During the installation process, start by calculating the pitch of your roof. Then, follow the manufacturer’s recommendations regarding the amount of overlap that you should use.
Metal Roofing Installation Guide Step By Step
When installing a metal roof, there a many steps you will need to take to make sure the roof is installed properly. Following this metal roofing guide will help to ensure you do not run into any issues installing your metal roof or afterward the metal roofing shingles are in place. To install your metal roof, follow these steps:
How Much Does A Metal Roof Cost
To the surprise of many, some metal roofs do not cost much more than an asphalt roof. The difference often lies in the installation costs. Simply put, more roofing companies do asphalt shingles. The more competition, the lower the price.
If you are using a commonly found brand and style of metal roofing, then expecting to pay around more than you would for asphalt shingles. Of course, that price can balloon if you want a different color, style, or brand of tin roof.
For instance, one square of asphalt roofing will cost around $100. Metal panels are commonly found in 10, 12, and 16 lengths. A panel that is 10 long and 36 wide would require 3.5 panels to make a square. If one panel is $30, then you are looking at about $115. Of course, that is for the cheapest type of metal roofing.

Which Standing Seam Panel Is Most Common
The Snap Lockpanel is the most common type of standing seam panel. It offers excellent performance and style, while also offering a greater value than nail strip and an easier installation than mechanically seamed. However, mechanically seam panels are excellent for a low roof slope and should be used in areas with extreme weather conditions as they are extra weathertight.
Snap Lock is a clip system that, unlike mechanically seamed, does not have the additional labor of seaming each panel together. This makes for a faster installation.

Install The Metal Roof Panels
Installing the metal roof panel depends on the type of metal roof product you have, but start at the edge and make sure your first panel overlaps the existing edging by an inch, if applicable. Otherwise run your first panel flush with the rake edge of your roof and 1 over the eave if you have gutters 3 if you dont have gutters.
The top of the metal panel should be flush or no more than an inch below the peak of the gable roof. Screw in your panels according to manufacturer directions. See above for rules about how many screws to use our rule was 80 per square of roofing.
If screwing into the rib of the metal panel, be careful to not screw too far and dent the rib and overly compress the neoprene washer. If you have metal panels overlap at a rib you can also use metal lap screws, which connect the panels but do not go into the sheathing. These are also used for roof edging that go over metal roof rake ends.
If your metal roof product says you need mastic tape and sealant to put beneath the panel seams, then go ahead and apply. Do it slowly as the tape can be difficult to work with.
Chances are your final piece of roof will need a lengthwise cut to fit the width of your shed roof. If so, a circular saw with a metal cutting blade works really well. You can also use tin snips but cutting long pieces with snips is awkward and arduous.

Skylights, curbs, chimneys, and other penetrations from your roof also add additional challenges when installing a metal roof. When detailing your steel roof installation, these extra features will need to be measured and included in your installation plans. Make sure you have all the dimensions of each fixture measured and outlined accurately before installing any panels or flashing. If the roof has skylights, check the weathertight warranty and engineering requirements before you begin to install the metal roof panels.

MYTH: Theyre only for farmhouses.
REALITY: While metal roofs are a familiar sight in rural areason houses, barns, and industrial buildingsthey can work on almost any architectural style. Todays metal roofing products can mimic wood shakes, slate, clay tile, and even granule-coated asphalt, making it likely theres a version to match your house style.
MYTH: Theyre vulnerable to hail
REALITY: Hail can damage roofing of any kind, if the hailstones are big enough. In areas where hail occurs frequently, you want metal roofing with a Class 4 rating. This rating indicates that the roofing has withstood ULs most severe impact test standarda 2-inch diameter steel ball dropped from 20 feetwithout tearing, fracturing, cracking, or splitting.

Luckily, metal roofs are incredibly lightweight compared to other roofing materials.
