1/2 Or 5/8 Roof Sheathing?
Are you scratching your head over whether to go with 1/2″ or 5/8″ roof sheathing?
Don’t worry, you’re not alone. It’s a decision that can make a big difference in how your roof holds up over the years, and it’s got a lot of people debating.
But fear not – this post is here to help!
I’ll compare both these sizes and help you nail down the best choice for your situation.
1/2″ Vs 5/8″ Roof Sheathing
The main difference between 1/2″ and 5/8″ roof sheathing is that 1/2″ is lighter, cheaper, easier to install, and is great for areas with moderate weather conditions.
On the other hand, 5/8″ sheathing offers greater strength and durability, better resistance to extreme weather and performs better long-term.
Let me go over these in more detail:

#1 Climate And Weather Conditions
Where you live plays a big part in choosing your roof sheathing thickness.
If you’re in an area with pretty normal weather, 1/2 sheathing usually does the trick for most homes.
It’ll keep the rain out and stand up to regular winds just fine.
But if you’re in a place that gets hit by nasty weather like hurricanes, tons of snow, or super strong winds, you might want to think about going with 5/8″ sheathing.
It’s tougher and can handle those extreme conditions better.
For example, lots of folks in central Florida, where hurricanes are a real concern, are choosing 5/8″ to make their roofs stronger and safer.
#2 Roof Pitch And Design
The steepness of your roof and how it’s designed are also important things to think about.
For roofs that aren’t too steep (think a 6:12 pitch or less), 1/2″ sheathing usually works well, especially if your rafters or trusses are pretty close together (16 inches or less).
This setup is good enough for most homes in areas without crazy weather.
But if your roof is steeper (more than a 6:12 pitch) or the rafters are further apart (24 inches or more), you might want to go with 5/8″ sheathing.
It’s stronger and helps keep everything nice and straight.
This is really important for complicated roof designs with lots of angles and intersections.

#3 Structural Integrity And Long-Term Performance
5/8″ sheathing offers better long term performance and structural integrity 1/2 sheathing.
It’s less likely to warp or sag as the years go by.
If you look at older homes, you’ll often notice that the ones with 5/8″ sheathing still have smoother, more even roofs.
Another cool thing about 5/8″ sheathing is that it’s better at holding nails in place. This is super important in windy areas or if you’re using heavier roofing materials.
The nails can go in deeper, which means they’re less likely to pop out over time.
While 1/2″ sheathing can still do a good job in many cases, going with 5/8″ might help you sleep better at night knowing your roof is extra sturdy.
#4 Cost And Installation Considerations
1/2″ sheathing is cheaper than 5/8″, both for the materials and labor. The thinner sheets are lighter and easier to handle, which can make the job go faster and cost less in labor.
If you’re trying to stick to a budget, it can be a good choice.
But here’s something to think about: while 5/8″ sheathing might cost more upfront, it could save you money in the long run.
Because it’s tougher, you might not need to fix or replace your roof as often.
Plus, in some cases, using 5/8″ sheathing means you don’t need to use H-clips between rafters, which could offset some of the extra cost.
#5 Roofing Material Compatibility
The type of roofing material you want to use can also help decide between 1/2″ or 5/8″ sheathing.
For regular asphalt shingles, which aren’t too heavy, 1/2″ sheathing is usually fine if your rafters or trusses are spaced right. But if you’re going for something heavier like clay tiles, slate, or fancy architectural shingles, you might need the extra strength of 5/8″ sheathing.

It’s also worth mentioning that some roofing material makers have specific rules about how thick your sheathing needs to be.
You must follow these rules to keep your warranty valid.
So always check what the roofing material manufacturer says before you decide.
#6 Weight And Handling
The weight difference between 1/2″ and 5/8″ sheathing might not seem like a big deal, but it can matter when you’re actually putting the roof on.
The 1/2″ sheets are lighter, which makes them easier to move around, especially on steep roofs or in tight spots.
This can make the job go faster and be safer for the workers.
On the flip side, 5/8″ sheets are heavier, but some roofers like how solid they feel when walking on them during installation.
Building Code Compliance
Now, no matter what you prefer, you’ve got to follow your local building codes.
These codes often have specific rules about how thick your roof sheathing needs to be, based on things like:
- How steep your roof is
- How tall your building is
- What the weather’s like in your area
These rules can be really different depending on where you live.
For example, some places that get hit by hurricanes or lots of snow might require 5/8″ sheathing for all homes. In other areas with milder weather, 1/2″ might be totally fine.
It’s super important to check with your local building department or a licensed contractor to make sure your choice meets all the rules.
Should You Choose 5/8 Or 1/2 Roof Sheathing?
Deciding between 5/8″ and 1/2″ roof sheathing really depends on your specific situation.
If you live somewhere with extreme weather, have a complicated or steep roof, or plan to use heavy roofing materials, 5/8″ sheathing is probably the way to go.
It’s stronger, lasts longer, and might even save you money in the long run.
But if you’re in an area with normal weather, have a simple roof that isn’t too steep, and you’re using regular roofing materials, 1/2″ sheathing might be just fine.
It can save you some money without sacrificing too much performance, as long as it meets your local building codes.
