Metal roofs are gaining in popularity as homeowners recognize their energy efficiency, durability and enhanced aesthetics. Manufacturers have responded by creating shingles with a variety of colors and textures that mimic materials that do not last as long, cost more or require more maintenance. Understanding how a metal shingle roof is installed helps homeowners to plan for the process of putting new roofing their homes.

The first step in metal roof installation is to choose the materials that are best suited to the style of the home and pitch of the roof decking. A Sugar Land roofing contractor can help a property owner sort through all the different options.

Next, the old roof will be torn off of the structure. The wood decking will be prepared with a vapor barrier and waterproofing layer to protect it from the infiltration of condensation or water. A single ply of roofing felt may also be attached if necessary. If the homeowner wishes, a layer of insulation can be applied there as well. Foam core board insulation is the type most often used with metal roofing systems, as the foam is lightweight and helps lessen any noise associated with rain falling onto the metal.

At this point, the roofers can begin applying the metal shingles. Only one layer is needed, although they may be installed with a slight overlap, much like the installation techniques for asphalt shingles or slate tiles.

However, rather starting from the bottom and working upward, metal shingles are installed beginning at the roof's peak. The shingles are placed next to one another along the ridge. A line of ridge caps and flashing are then installed. On the second row, the crew begins with a shingle cut in half to create the familiar staggered look. After this, the installers work their way down each face of the roof. Each row of shingles interlocks underneath the row above it.

For the final row of shingles placed on each slope of the roof, a drip edge is installed. This overlaps the gutter so that rain can drip into its structure rather than down the side of the house. Flashing strips are placed at each valley and around any rooftop protrusions such as chimneys, furnace flues and vent openings. If gutters need to be installed, they must be made of the same type of metal as the shingles, otherwise the process of galvanic corrosion may cause the shingles or gutters to prematurely wear out, develop holes or crack. This damage can allow moisture to enter the infrastructure.
