Morris County Roofers: Article About Dealing With Frosty Roof Nails
When asphalt shingles are installed on the roof, the very tips of the nails will penetrate the roof sheathing so that they are visible from inside the attic. When the temperatures are right, frost may actually form on the nail tips. If homeowners discover that there is frost in the attic or on the tips of the roofing nails, professional Morris County roofers should be contacted.
Essentially what is happening is that warm air is seeping from living space. Since the roofing nails are thermal conductors, they are the same temperature as the outside environment. This means that when the temperatures drop below freezing, the nails will also become very cold. When the moisture in the air meets the cold metal of the roofing nails, frost can form. Not only can this eventually lead to mold growth, it can also reduce how effective the insulation is.
A little bit of frost in the attic is not going to cause too many problems as long as the homeowner is vigilant when it comes to roof inspections. However, since warm air is leaking out of the living space, that is costing the homeowner more money because the heater works harder to replace the hot air that is lost. There are two ways that roofers can fix the problem.
The roofing contractors from Peter W Smith Construction of Morris County would be happy to answer any questions you have about roof repair or roof replacement.
First, the reason that warm air is leaking into the attic is because the attic is not air sealed. Roofers will look for holes and cracks in the attic floor and the hatch these can be patched using weather stripping. Air sealing will provide additional benefits as the cost of heating should go down and the amount of moisture in the attic should be reduced.
Second, a roofer should inspect the roof's ventilation system to ensure that it is working properly. If moisture gets into the attic, the vents in the roof will allow fresh air to come in through an intake vent and the moisture laden air to escape through an outtake vent. If the home has box vents, the roofer may recommend having soffit vents and a ridge vent installed to make sure air moves through the attic.
Temperature problems that occur in the attic can lead to damages and cause the roofing materials to wear faster than they should. Professional roofers should always be contacted to determine what the problem is and how to best fix it so that the roofing materials last longer and the homeowner saves money on cooling and heating costs.
