Choosing The Wrong Materials For The Slope Of Your Roof
Even if the materials are new, choosing the wrong ones for your roofs slope will provide very little protection from rain and moisture permeating your roof. Asphalt shingles, for example, arent waterproof by any means so having too low of a slope will allow water to pool and permeate the barrier that these shingles provide. If your roofs slope is at least 4 units of rise per 12 units of run, asphalt shingles will do just fine. Otherwise, speak to your roofing contractor about other material options.
How Many Cap Nails Per Square Of Underlayment
The roof is indeed one of the most crucial elements of the buildings structure. To install the roofing successfully, then one needs to invest a significant amount of money and time. A minor mistake might cost you pricey fixing work, so its always recommended to hire or at least discuss your roofing project with a professional roofer or contractor.
That being said, there are some simple matters that you can do yourself, such as doing simple math over how many roofing nails per square of underlayment that you need. Though of course, you need to know your roof size first to do the estimation.

The key to performing a successful roofing project is knowing how much height the roof must bear which is crucial information if you work with aged framing and foundation. One of the factors that add up the roof weight estimation is the nails weights that will hold the roof underlayment and shingles in their place.
The majority of roofing manufacturers advise that you use four nails for each shingle for the roofing main area and use five nails for each roofing underlayment square. This means that youll need 320 nails per square foot. For you who live in windy areas, you may want to use 480 nails per square.
The most commonly used nail type is the 1.5 roofing nail, which has 7/16 flathead and 11-gauge smooth shank. The nails are resistant to extreme weather such as rain or sun because theyre hot galvanized.
Additional Tips For The Work
Some roofing coil nailers have an adjustable shingle guide. This lets you automatically set the position of the nail with respect to the bottom of the shingle. This is extremely handy, though after a while you will likely find yourself, guide-free, nailing away quickly and accurately once youve done a couple of rows.
We recommend a 6 nail pattern regardless of whether or not you live in a high-wind area. It simply doesnt take all that much more effort. Most people use pneumatic roofing nailers, so adding n extra couple of hits takes little effort. The cost certainly isnt much more either. Take into account the hassle associated with any kind of early roofing material failure, and youll probably agree that a little extra time and money spent up front can save a lot of hassle down the road.

Nail Per Shingle: How Many To Use
- Written by Brynn Dahlquist on Jun 29, 2010To ensure our content is always up-to-date with current information, best practices, and professional advice, articles are routinely reviewed by industry experts with years of hands-on experience.Reviewed by Hannah Madans on Mar 19, 2020
When reshingling a roof, shingle nails need to be placed appropriately in order to keep elements out and the shingles on.
Standard roof installation requires four nails per shingle. The rationale behind the number is that in most cases four nails are the right number of nails to do a quality job. However, placement of the nails is the most important in any roofing job. A “nail line” is indicated on the shingles and locates the correct places to put nails. Nails placed above the nail line endanger the shingle of being ripped off during high winds or extreme weather.
Steep Slope or High Wind
Very steep slopes, also called Mansard roofs, as well as areas with extremely high winds, require six nails per shingle to allow enough hold against the elements. The extreme slope means that not only is there a larger pull from gravity on each shingle, but also substances are going to flow faster across the surface. The added friction requires more nails in order to adequately hold the shingle in place. There is no reason six nails cannot be used on a standard roof, but with the extra money and time necessary to add the extra nails, it is often considered unnecessary.
What About The Waste Factor Should I Order Extra Roofing Materials
You want to order extra material to account for waste. Waste factors vary.
10%-15% is a good rule of thumb, but your results may be different. More complicated roofs will have a higher waste factor because there are usually more cut shingles around corners, walls, and edges.
It is okay to have a few shingles left over. They can be saved in case there is roof damage later or if repairs need to be done in the future.
So for the 24 square roof example, you would want to add 2.4 squares which equal about 7 or 8 more bundles.

Not Using Nails Correctly
Something as simple using too few nails can actually be very detrimental to the longevity of your roof. To save on costs, some less than honourable contractors may use too few nails to secure your shingles. As a rule of thumb, no fewer than 4 nails should be used per shingle improperly secured shingles can come loose and a loose or missing shingle doesnt do a very good job of diverting water.
Nailing too high or too low can also be a big problem. Shingles have a nailing strip that should be used when securing your shingles to your roof. When roofers properly use the nail strip, all of your shingles will be held much more securely in place. For example, if you use 4 nails per shingle, each shingle will, in actuality, have at least 8 nails holding it in place. This is because using the nail strip will actually catch the underlying shingle. At DAngelo and Sons, we go one step further by using 6 nails per shingles, meaning that your roof will be even more secure.
Failing To Take The Winter Climate Into Consideration
If you live in an area that sees some pretty harsh winters, your roof may be prone to the formation of ice dams. Ice dams occur when heat escapes a homes attic, melting the snow on the roof. The snowmelt then freezes and, over time, an ice dam develops. Ice dams are notorious for allowing runoff to enter between the shingles. A responsible roofer will anticipate the possibility of ice dams and install an adequate underlayer in the roof to protect against the formation of ice dams.

That answers the question about the minimum number of nails and were sure you realize that the minimum will be good enough for fast buck roofing companies, plus theyll use the cheapest roofing nail they can find.
Answering the question about how many nails we use per shingle is a bit different and well go light on the technical details yet not so light that we end up being vague. We use 4-6 nails per shingle, depending on the area and steepness of the roof. Let us explain a bit more.
First, our nails are 1¼ inch hot dipped galvanized, ring shanked for extra bite versus a smooth shank that is less secure. These nails are installed using an air driven nail gun to assure the shingles are fully secured. Each nail actually goes through two shingles the one that is getting nailed and the one underneath it. That is why every shingle is actually getting 12 nails.
The value of how many nails we use, and the type of nails, has less meaning without converting it to how much wind your roof will withstand. Our installation method will endure hurricane velocity winds exceeding 130 MPH. Thats beyond even the worst gusts you should ever have to worry about in Southeast Michigan.

Should roofing nails go through the sheathing?

How To Fix Nail Pops In A Roof
Nails can pop above the roof surface for a number of reasons. Perhaps they were underdriven in the first place. Nails that didnt fully penetrate the sheathing may work their way up over time. Or, if a roofs decking has warped or bent, it can pull nails out of place. Whatever the cause, its important to fix any nail pops in a roof to prevent damage.
Fixing the nails is simply a matter of removing them, removing the shingle and installing a new shingle. Be sure you to use the correct nail length and place it properly.
Do not simply hammer the nail down, renail it in the same spot, or use the same shingle. All of these methods could allow water through the roof. For example, if you remove the nail and drive it back into the same spot, your aim wont be perfectly accurate. There will be a tiny gap on one side of the nail or the other. Even if it is imperceptible to you, water will find it.
If you use the same shingle and add the nail back in a different spot, youre leaving behind a hole where the nail once was. Some suggest you fill this hole with roofing cement, but this repair option must be done carefully to maintain the roofs water-shedding performance.
