Siding Nailer vs Roofing Nailer: Which is Best for Your Needs?

Can you use roofing nails for siding

They look similar and they perform the same task, but that doesn’t mean that siding nailers and roof nailers are the same tool. Both tools are coil nailers that are built to drive nails into wood, but you can’t use them interchangeably. You might have noticed the price difference between them already, but it’s the reasons for the price difference that really separate these two types of nail guns.

Each nailer is named for the job they fill. Siding nailers are for installing siding and roofing nailers are meant for installing roofing. But did you realize that different nails are used for each task? Let’s take a closer look at each of these useful tools and see which one is the best choice for your situation.

Siding Nailer Overview

At its heart, a siding nailer is a coiler nailer designed for installing siding onto exterior walls. They look the same as roofing nailers, and they even operate in the same basic fashion. The main difference between these two types of nail guns is in the nails they use.

These Nails Don’t Come Out

Nails meant for holding up siding are intended to stay put. Siding isn’t meant to be replaced as often as roofing, so the nails are ring-shanked to provide a better hold. They also have small heads for the same reason.

Don’t Fire it Flush

Most of the time when you install a nail, you’re going to install it flush with the surface. But that’s not the case with a siding nail. Since siding is susceptible to the whims of nature, it’s going to experience a lot of expansion and contraction. Because of this, siding nails aren’t installed flush. Instead, a small gap is left between the head of the nail and the siding to allow for normal expansion and contraction. Otherwise, your siding would crack. 

Adjustable Depth

Since siding is installed on a vertical surface, holding it up requires a lot more force than holding on roofing that’s laying on a horizontal surface. As a result, siding nails are much longer than roofing nails; often as long as 2½ inches. To account for this, siding nailers have adjustable depth controls to allow you to alter how far the nail is being driven.

Longer Nails, Larger Price

Siding nailers tend to be quite a bit more expensive than roofing nailers, driving many to look at roofing nailers as an alternative. But if you need to drive long nails, only the siding nailer will let you do it.

Looking at them side by side, it can still be difficult to tell a roofing nailer apart from a siding nailer. Since roofing nailers are much cheaper, many would prefer to purchase one to perform the job of a siding nailer. But these fire completely different fasteners, so that’s not going to work the way you might hope.

These Nails Need to Come Out

Unlike siding nails, roofing nails need to come out. Roof shingles need to be replaced occasionally, so the nails have larger heads that are easier to grab. They also have smooth shanks that will pull out much easier than the ringed shanks you’ll find on siding nails.

Punching Through Asphalt

Roofing nailers have to punch their nails through asphalt shingles; an arguably more difficult job than nailing through siding. But since these nails have to hold the shingles flush to the roof, the nails are installed flush as well.

Shorter Nails

Installing shingles doesn’t require long nails since they’re thin. Therefore, roofing nails are generally no longer than 1¾ inches. This is the most glaring difference that sets a roofing nailer apart from a siding nailer. Siding nailers use much longer nails that basically start where roofing nails end.

Smaller Nails, Smaller Price Tag

Since they use smaller nails, roofing nailers tend to also come with a smaller price tag. This is probably the most appealing aspect of a roofing nailer and why some people would prefer to purchase a roofing nailer if it will serve their needs.
