Dallas Roofing: Article About Determining The Right Roofing Material
Most homeowners rely heavily on Dallas roofing professionals for advice and suggestions when installing a new roof. They will often ask questions about everything from the type of roofing material to use to how long the installation process should take.
When determining the best asphalt shingle to use on a roof, homeowners must consider multiple factors. These include the quality, the quantity and compatibility of the shingling material they want to use. Special attention should be paid to how the shingles are reinforced and what type of surface granules are used. There are two types of shingle reinforcements. They are organic fibers and a fiberglass mat. Fiberglass shingles provide better fire protection and are more moisture resistant than their organic counterparts. On the other side of the coin, organic shingles provide good protection against the wind, are very strong and resist any damage caused by the freeze and thaw cycle that exists in northern parts of the United States.
The American Society for Testing and Materials sets guidelines for asphalt shingles. Fiberglass shingles must meet the ASTM D 3462 standard, whereas organic shingles must meet to the ASTM D 225 standard.

Just because a roofing material has a long warranty does not guarantee that it will provide satisfactory roofing performance. Customers are encouraged to look at the NRCA's warranty standard to get a good idea of how they affect the materials they are selecting.
Having the right underlayment is just as important as using quality roofing materials. The two most common roofing underlayments are No. 15 and No. 30. The NRCA recommends that any roof that has a slope of 4:12 or greater use two layers of number 15 asphalt-saturated underlayment. Heavier shingles, such as those made from slate or asphalt, may require the use of a number 30 underlayment instead. Homeowners should be aware of the fact that two layers of number 15 underlayment does not provide the same protection as one layer of number 30 underlayment.
Just as important as the roofing material used and the underlayment used is the fasteners that a contractor applies to secure the roofing material to the roof's deck. The NRCA recommends that galvanized steel or some other form of corrosion resistant roofing nails be used. In most cases, staples would not be a viable replacement for nails.
When working with metal roofs, contractors should guarantee that the fasteners used are made of the same metal as the roofing material. If not, the two different metals could react poorly with each other and lead to accelerated corrosion.
