How to Measure A Roof for Metal Roofing [5 Easy Steps]

Metal roofing is comparatively shorter to build and appealing with looks.

You can also have variations in the color of the roof, changing the look of your house. But how to do it!

How to measure a roof for metal roofing?

First, make an estimated design and measure the distance of edges. Then measure the distance from the fascia boards. Finally, note down all the measurements properly and get started with your next work. That is, you can now start installing metal roofing.

It’s just a brief so far. Keep on reading to know more relevant information that I have got in the article!

How Do I Measure For Metal Roofing?

Measuring a roof is not that critical. But the measurement has to be precise and accurate enough. Or else, the roofing would not be appropriate and can have metal roofing issues in the future.

Here, I have divided the steps of measurement into 5 different steps in detail. Take a look now.

Required Tools

Before you get started with the measurement, you need to have a few supplies. But don’t worry! The tools you need are not that tough to manage:

  • Measuring Tape
  • Hand Gloves
  • Calculator
  • Permanent Markers

Once you are ready with the supplies, you can get started with the measurement.

Step 1: Make An Estimated Design

Begin by designing a top-down picture of the roof of the house. Don’t stress over having the scale and dimensions exactly right just yet. 

Measure the length of your roof. You need to do it too if you want to have metal roofing over plywood.

Step 2: Measure The Distance of The Edges

Measure from any of the edges to the other side to do so. In the next stage, jot down the number. Next, determine the breadth of the metal you’re going to install. 

Then multiply the length of the roof by the metal’s breadth. 

Step 3: Double The Length

The length of your roof could be 30 linear feet which are 360 inches. 

When you double that by the width of a 24-inch standing seam roof, you get 15. This is basically how many panels you’ll require for one roof side.

Make sure to use a calculator when you are calculating. It’s better if you have a square idea of roofing for this.

Step 4: Measure from The Fascia Board

It’s crucial to take measurements on both sides in case their sizes differ somewhat. 

Measure from the fascia board to the roof’s peak. The fascia board is the board that connects to the roof joists. 

If you want to replace the fascia board, then it’s a good time.

Step 5: Note Down All The Measurements

Finally, you need to note down all the measurements properly. If you are confused about any measurement, you may take it again. But don’t keep any confusion at the measurement stage.

Remember to note down the total weight of the materials too.

After you have successfully measured them all, you are good to start the installation!

How to Install A Metal Roofing?

Installing metal roofing is not that easy. But it is nothing impossible, you just have to be careful enough.

I have covered it in a few steps. Take a look here.

Step 1: Apply Underlayment

First, you need to apply the underlayment. Make sure you keep it flat and no wrinkle is formed. Cut and curl the front end of the trim to loop it around the edge before installing it. 

To make tabs, create a series of one-inch cuts with aviation snips at each curve. To reach a wall or a corner, use a hand seamer to bend the tabs in. 

Each trim has a unique shape that necessitates specific cuts and bends.

Step 2: Set Panels

Set metal panels on a foam closing strip on the inside. The strips are tailored to the panel’s corrugated bottom. Bugs and water won’t be able to get below. 

Then fasten the screws properly.

The metal panels have two different edges. When lying flat, the overlapped edge has a smaller rib leg that does not meet the roof surface.

Step 3: Overlap Panels

Now overlap the panels. The overlapping edge would have a shorter rib leg and it wouldn’t meet the roof surface. 

Finally, secure the ridge cap and you are done with the installation.

These are the steps to installing metal roofing. For any confusion, talk to the professionals. And they can even complete the entire installation process more easily.

On a side note, if you are looking for sheets for your roof. You can look into polycarbonate sheets which are both modern and cost-efficient.


Question: How much would it cost to build a metal roof of a 1500 sq. ft. house?

Answer: The cost to build a metal roof for a 1500 sq. ft. house would be quite significant. It can take from $5,000 to $9,000 depending on a few other factors. The cost can also vary due to demographic variation. 

Question: Is metal roofing or shingles cheaper to get?

Answer: Well, metal roofing is never cheaper than shingles. In fact, metal roofing is quite expensive compared to the other ones. Shingles would cost around $5 per sq. ft. Whereas, metal roofing would cost you more than $15 per sq. ft.

Question: What are the possible drawbacks to face metal roofing?

Answer: The first drawback of metal roofing is the high expense when building it. In addition to that, if the color mismatches anyway, it wouldn’t look ideal. Metal roofing particles may also get rust with time. The maintenance also needs to be sincerely observed.

Final Words

Now you know how to measure a roof for metal roofing! I tried to explain all the points in detail so that you understand properly.

Hold on! I have a bonus tip for you. You’d see the sidelines of the metal sheets are rigid.

Don’t bend the sheets when you move them. This would make your work easier!

Good luck!
