No more than 650 lbs of roofing may be applied to a residential home without an engineering analysis performed by a professional engineer. 3-tab shingles weigh 210lbs per square and you can have up to 2 layers of these types of shingles. If you are looking to do a roof replacement on your home, its important to hire a knowledgeable roofing company that will guide you through the process, keep your home safe, and educate you on possible solutions.
Roof slopes must be greater than 2/12 slope to allow 36 inch strip shingles, such as 3-tabs, or dimensional. Roofing systems with a 2/12 to 4/12 do require an additional layer of roofing felt, or a layer of ice, and water shield under them to prevent driving rain that may get under the shingles, causing costly roofing damage. We install drip edge on all shingle roofs unless the owner specifies otherwise.
Choosing the best roofing material involves considering the beauty, practicality, and affordability of roofing materials that are available to homeowners. Homeowners and property owners in Arizona have several roofing material choices from which to choose, including tile roofing, shingle roofing, metal roofing, foam roofing, and more. Each choice can satisfy a homeowner’s needs and desires for his or her new roof. To make your roofing selection, visit our roofing page.
