How To Measure For A Metal Roof. Most homes, particularly conventional residential homes, have non-square roofs, making it difficult to determine which type of metal roofing is appropriate for your property.
For example, the kind and pitch of your roof can influence a variety of factors, such as whether you want a standing seam or corrugated metal roof, and how much surface area you’ll require.
Thankfully, we at Roofing Superstore have put together some guidelines on how to precisely measure.
How To Measure For A Metal Roof
Start off by sketching out a top-down view of your home’s roof. Mark the length of the roof on your drawing. Next, figure out the width of metal that you will be installing. Repeat the process on the other side of the roof.
This article discusses how to measure a metal roof.
Sketching And Measure
Look towards drafting up a rough sketch of your home’s roof, but do not be concerned about getting the measurements perfect yet.
To begin with, you will need to measure the length of your roof by measuring from one side to the opposite edge.
Figuring Out Width
The next thing you’ll need to find out is the width of your metal panel. Then, simply divide the length of your roof by the width of your metal.
For example, your roof might measure 30 linear feet inside. Divide that by 24-inch standing seam panels and you reach 15 individual panels.
This means you’ll need 15 panels on one side of the roof only. Take the same measurements on the other side of the roof.
In case there’s a difference in size compared to the side you measured first, it’s best to know about it before you start working so as not to be caught off-guard or waste any time redoing something that could’ve been avoided from the beginning.
Measure Fascia Board
Measure the distance between the fascia boards and the ridge of the roof. Using that information, you can calculate the number of metal panels needed to cover the roof on that side.
FAQs
What is the best way to measure for a new metal roof?
Measure from the fascia board to the ridge of your roof to determine the length of metal panels you’ll need.
Take measurements using a tape measure or, if you have one, a laser level. For example, if your roof reaches a peak height of 12 feet, you’ll require 12 feet of metal panels.
A metal roof should have how much overhang?
A metal roof overhang is typically 2 to 4 inches, but some slight overhang is recommended in conjunction with a drip edge flashing to prevent water from getting under the roofing and onto the underlying wood.
Under a metal roof, do I need furring strips?
If one installs a metal roof over an existing roof, it’s essential to make sure there is adequate insulation in-between the strips of wood so that there isn’t excessive condensation under the new roof.
You’ll also want to add additional furring material to help you secure the new material when installing your metal sheeting. 24 inches is an adequate spacing of furring material for a metal roofing project.
