Typically, a three-tab composite shingle will be the least expensive to install in terms of material costs and labor.  The material cost will increase if you move to a heavier architectural composite shingle. There are also specialized composite shingles to choose from that offer features such as increased impact resistance or a reflective, cool surface. While material costs will vary based on the choice, labor costs are generally similar across all composite shingles.

Labor costs are going to be higher to install a metal roof than a shingle roof. Metal roofs are very popular in Texas and come in several varieties with the most common being exposed fastener systems, snap lock fastener systems and mechanically fastened systems.

Metal roofs come in different thicknesses (gauges), panel widths and have many varieties of standing seams. Generally, the heavier the gauge, the more the panel will cost. The finish can be a factor in cost as well with galvalume finish being less expensive than a premium color finish. Standing seam panels (snap lock and mechanically fastened) have more parts required for installation but offer the advantage of not having the fasteners exposed. So while an exposed fastener system will cost less initially, it will need more maintenance as it ages and fasteners loosen or grommets become worn.
