Killeen Roofing: Article About The Thickness Of Metal Roofs
Metal roofing is gaining popularity at a rapid pace. Homeowners like it for its relatively low cost, low level of necessary maintenance and long life span. Homeowners new to metal roofing may have some questions. The most commonly asked question that homeowners have regards how such a thin sheet of metal can protect their roof for decades. It may seem like metal roofing is flimsy. However, Killeen roofing companies will measure it carefully to ensure that it is strong enough to do the job.
The thickness of metal roofing, and indeed the thickness of all metal products, is measured by gauge. The gauges used for metal roofing range from 24 gauge, which is the thickest, to 29 gauge, the thinnest. Experts recommend that homeowners not go below 29 gauge as the metal may not be thick enough to stand up to the elements. The experts also recommend that persons living in rainier climates go with a thicker gauge of metal, preferably 24 gauge.
The first thing a professional roofer will do when checking the thickness of a metal roof is find a suitable location on the roof where he can collect a measurement. Roofers usually choose the edge of the roof as this area is easy to access.
Once the roofers have chosen an area to measure, they must gain access to it.

For an area on the edge of a roof, the roofers merely need to lay a ladder against the house and climb up it. An experienced roofer will have an assistant hold the base of the ladder.
Once within reach of the roof, the roofer will use his gauge to measure its thickness. There are gauges made specifically for roofing, and a professional will no doubt have one of these. These gauges have calipers made specifically for measuring roofing.
The actual taking of the measurement is fairly easy for an experienced roofer. He will place the calipers flat on the roof. The calipers must be applied with enough pressure that they lie perfectly level but not with so much pressure that they dent the roof.
After the first measurement has been taken, the roofer will take at least two other measurements to ensure he has an accurate reading of the entire roof. These measurements must then be added together and divided to get an average. The average should be within one or two numbers of the original measurement. For example, if the roofing was 24 gauge when it was new, it should be no less than 26 gauge now.
