When the temperature changes, expansion and contraction can cause your nails to rise and lift up shingles. You should also ensure that your roof is properly ventilated. Other causes of nail breakage may be that the shingles weren't properly nailed when the roof was installed. Each asphalt roof is made up of individual shingles.
Roofing contractors use hammers or pneumatic nailers to attach shingles to the roof covering. Most shingles require 4 to 6 nails per shingle. Also, consider having your roof repaired every 8 to 10 years to repair damaged shingles, busted nails, and worn roof boots.Roofing nails that stick out, called busted nails, may seem like a minor problem. However, they can cause leaks, especially if you have an asphalt shingle roof.
The nails may have broken because they weren't installed correctly or due to daily changes in temperature and humidity; whatever the reason, you can protect your roof by fixing the nails quickly.Before taking the ladder and venturing out to the roof, it's important to talk to an expert to find out if there are nails in the type of roof you need to repair and if it's safe for you to tackle the project yourself. It's quite possible that your roof covering consists of numerous 1 x 6 spackled boards. By forcing the shingles upward, they create a path for wind-driven rain to reach the roof lining and enter the house as a roof leak.The same can happen on roofs that have large pieces of 4 x 8 inch plywood or an oriented laminated cardboard coating. If the roof nail penetrates the coating along this seam, there is very little solid wood left to hold the nail.
By forcing the shingles upwards, the folded nails break the joint between the shingles created by the self-sealing strip of the shingles or by any added roofing cement.These small insects, although they seem harmless, can cause roof leaks, damage the coating and release tiles. The wooden ceiling coating (plywood, OSB, wooden planks) swells due to increased humidity and high temperatures.If you're currently looking for a new roof, take some time to become a technical expert, at least on the basics. Spread a layer of asphalt cement over the new nail and the old nail hole if you have a flat asphalt roof.Roof nails are often a common problem in roofs with poorly ventilated attics, where extreme overheating of the roof occurs, as well as in roofs that were installed when the roof covering was not dry. Recently, leaks began to appear in several areas of my house and, upon inspection, it was found that the nails on the roof had fallen off and had pierced through the shingles.With thousands of nails used in every ceiling installation, it's nearly impossible to ensure that all of them are installed perfectly.
Another situation in which it is common for nails to break in roofs is where a second layer of shingles has been installed on top of an existing roof.Roof coverings are large wooden planks that cover the beams and act as a base for the shingles to be nailed.
