Should Corrugated Metal Roofing Be Pre
Since screws used to install metal roofing are self-drilling screws, or screws that drill their own holes through the panel into the substrate, many contractors would argue that pre-drilling is not necessary. In fact, it could actually be very difficult to do if the metal roofing panel is being installed over metal purlins due to spacing. However, there are circumstances when pre-drilling panels does make sense.
Is Underlayment Necessary For A Metal Roof
No, underlayment for a metal roof on a shed is not necessary. A properly installed metal roof does not need a second waterproof layer on a shed. If you intend to heat your shed, however, then you will need underlayment to protect against condensation damage.
Neglecting to use underlayment isnt a bad choice for shed owners unless you dont install your metal roof properly. In that case, your roof sheathing will rot, decay, and eventually have structural failure if you dont rectify the problem in a timely manner.
Tar paper or Tyvek wrap can be used, too. Tar paper is weather resistant, absorbs moisture and will let it evaporate over time. The drawback to tar paper is that if you have a constant leak, it will become too saturated and destroy the wood beneath it.
Housewrap, such as Tyvek, is a more durable alternative to tar paper but more expensive. It is waterproof but not a vapor barrier, so youll still get condensation on the underside of your metal roof. However, the wrap will still largely keep the water from getting onto your roof sheathing.
The best underlayment for a shed metal roof is waterproof self-adhering membrane. Once you apply it, you can rest easy. This membrane is like having two roofs on top of each other it is durable, waterproof, serves as an air barrier and holds up well in extremely hot and cold climates.
How To Install Metal Roofing To Plywood
Installing metal roofing over plywood is less time-intensive and more affordable than a shingle roof, but there are still several steps you should take when installing a metal roof to plywood to ensure that your roof does not leak and will stand the test of time.
Follow these steps when installing metal roofing on top of plywood:
Replacing rotten wood is critical because dry rot will spread. Adjacent areas of healthy plywood may eventually become rotten, and then the screws you have placed there will not hold. Warped wood should also be replaced. Warping signifies that the wood is prone to rot and will prevent you from laying the metal roofing flat. Wind will be able to get underneath the roofing and pull it off your roof.
Be sure to use plywood that is thick enough. The plywood or OSB you use for a base underneath your metal roofing should be at least 7/16 inch thick. This thickness will ensure that the wood is sturdy enough to hold the screws in place and support the metal roofing. .

What Tool Is Used To Install Fasteners On A Metal Roof
A screw gun, not a drill, is needed to install metal roofing. When you let go of the trigger on a drill, it will not disengage. If you do not release the trigger at the right time, the screws will be overdriven which can damage the washers or even the panels. Using a real screw gun such as the Dewalt DW266, DW267, DW268 or the Milwaukee 6780-20 and 6790-20 lessens this possibility.
Use an actual screw gun with an adjustable clutch and a depth sensing control feature. Screw guns are designed for the torque to be adjusted which eliminates over tightening of the screws. Overtightened fasteners is one of the biggest errors made during metal roofing installation. When a variable speed screw gun is used, you are able to change the speed to eliminate this problem.

Thoroughly Measure Your Roof
Before you purchase materials, make sure that your metal roofing will fit on your home. This is easiest to do if you measure out the space and take measurements before shopping for panels or shingles. But once you know what size of material to buy , be aware that not all metals come in standard sizes, so its good to have a little extra just in case.
1) Measure the Height of Your Roof
Measure your roof to determine how many panels are needed for installation. Some metal roofs come with pre-cut lengths, but if not, you will need some sort of measuring device like an accurate yardstick, measuring tape, a chalk and line system, or laser leveler. For the best results, make sure to use a ladder so you can get accurate measurements.
2) Measure the Length of Your Roof
Once you know how many panels are needed for installation, measure the length of your roof and order that amount in panels or shingles. Start at one end and take a reading from top to bottom with your measuring tape to measure correctly. At that point, measure the distance to the opposite end and add those two measurements together for your total length.
3) Measure the Pitch of Your Roof
Another critical number youll want to know is pitch this refers to how steeply sloped your roof is, or in other words, its incline measured from a horizontal plane. The pitch you want will depend on the type of metal roofing you buy because a steeper pitch means more material is needed for installation.

Can You Put Solar Panels On A Metal Roof
Metal roofs are lightweight, long-lasting, and frequently constructed of recyclable materials, making it no surprise that solar installation on metal roofs is becoming increasingly common among homeowners. The good news is that metal is one of the finest roofing materials for solar panels, as long as a few key installation guidelines are observed.
Even better, a metal roof can actually provide some benefits for solar installation. Metal roofs can increase the efficiency of solar thermal systems, as they can reflect more sunlight onto the collector panels. Additionally, metal is a good conductor of electricity and can help transfer energy from the panels to the inverter more effectively.

Bend Trim Ends Closed
- Before you install the trim, cut and bend the leading end to wrap it around the corner. Make a series of one-inch cuts with aviation snips at each bend to create tabs. Fold the tabs in with a hand seamer to meet a wall or a corner, or to close a gap created by the trim. Each trim is a different shape, requiring unique cuts and bends.
Being Aware Of Avoidable Errors Will Ensure A Quality Metal Roof
Installing a metal roof is a complicated process with many details. When a metal roof fails, while it could be due to its design, more likely it is due to installation problems. Improper installation can cause leaking, significant life span reduction and potentially damage an entire structure.

This will provide a solid foundation for attaching the metal panels or shingles onto and securing them by using nails, screws, or staples .

Drive Screws Just Right
- Fastening the panels just right is the key to a watertight roof. Here is what you should know:
- At the eave, place screws on both sides of every rib and lined up to go through the foam closure strip.
- Each row should be spaced no more than 24 inches with one screw at each rib on the overlapping side.
- Start at the bottom, fastening across the panel in rows, working toward the ridge.
- Drive screws to seat flat on the roof a crooked screw wont seal.
- Dont over-tighten or under-tighten. Tighten just enough to compress the rubber gasket to the edge of the screw head, not past it.
- Clean up any metal shavings or burrs right away. They will rust.
Remove Old Roofing And Repair Any Damage
While it is possible to install a metal roof over old asphalt shingles, a full tear-off of the old roof is highly recommended. Removing the old roof will allow you to inspect the sheathing and flashing and replace any problem areas before moving forward. That way, the sheathing and flashing can be inspected before the new roof goes down, reducing the chance of a leak.
- Start from the top of the roof and remove the old shingles along with the flashing, underlayment and vents.
- Hammer down or pull any large nails that are exposed by the removal.
- Inspect the underlying roof sheathing for damage and make any needed repairs with sealants and roofing adhesive.
- Install a layer of roofing underlayment, including a layer of felt paper or rosin slipsheet, as recommended by the roofing manufacturer. Metal panels expand and contract at different rates than the sheathing, so its important to follow manufacturers guidelines regarding underlayment.
