How Long Should Roofing Nails Be?
How long should roofing nails be? This is a common question among home owners when they are installing their roof. If the nails used are too short, there is a high risk of the shingles cracking and being removed. In addition to being a safety hazard, this also means that you need to replace the shingles sooner than anticipated. If you live in an area with cold weather, then you will also need more time to install the roofing nails because cold weather can cause the nails to crack.
When purchasing a roofing nail, always choose a contractor grade product. This means that it has been crafted and built to specifications by professional roofers and engineers. There are several brands available, so it pays to shop around and compare prices before making your final decision. Never purchase a roofing nail that is used only once. Always purchase a brand that is engineered for multiple uses. If you have a weak or shorter nail, you may want to try using a longer nail on the same location to ensure that the job will be completed quickly and easily.
The two types of nails commonly used are the round and the square. The round nail is most often used when building a roof over a concrete slab. Square nails are used when constructing over a wooden frame. These nails are usually used to install single shingles, or to cover multiple small nails that would otherwise be visible during a square installation. For better visual appearance, it is important to use smooth shanks rather than pointed ends.
If you are purchasing nails individually, always select ones that are pre-drilled to prevent them from splitting or ripping. You can use a nail gun to make sure that your nails are pre-drilled; however, this can be an awkward process. When you have selected the best nails for your project, you should place them into the nailing gun. Nail guns require you to load them up in their magazine prior to use, but they have a handy reservoir on the side of the device that allows you to pour tap water into the reservoir while the nail gun is loaded with nails.
Before you begin hammering the shingles onto the roof, you should create a mark on the shingle that corresponds to the number of screws you will need. This allows you to accurately count the number of nails you will need to complete the job. Using a felt tip pen, mark the position of the nails on the shingle. Once you have the exact number of nails necessary, you can then move on to hammering them into place.
Once you have the nails placed, you will want to apply some roofing cement. This will help the nails hold their position better as they are being driven down into the wood. If done correctly, you should be left with an eight-inch gap between the shingles and the roofing. To increase the holding power of the nails, you should apply more cement between the shingles and the roof. As the nails penetrate the wood, they will work their way into the gaps created by the cement.
