In areas of the nation that have generally moderate to warm climates, flat roofs are a common construction technique. They tend to cost less and may even feature more energy efficient systems compared to moderately pitched roofs. However, flat roofing systems are prone to problems like leaking and may not be as strong in the event of high winds, hail, ice and snowstorms. Homeowners can work with a reputable Houston roofing service to convert their flat roofs into roofing systems with a slope.
The first step in the conversion process is choosing the new roofing style. A gable roof is a popular choice, as are gambrel roofs and hipped roofs. A property owner may wish to hire an architect to create several sketches or plans before presenting these to a roofing service. Homeowners will find a vast array of roofing materials on the market to choose among, and he or she can customize roof tiles and shingles to individual color specifications.
Once a style has been selected, it is time to tear off the flat roof. This can typically be done by an experienced roofing crew in less than one day. Most contractors will recycle as much of the old materials as possible in order to minimize the environmental impact and lower the project's costs. Even asphalt and old wood can be recycled, in addition to any metal parts.

After the building is ready, the rooftop will be exposed to the decking. If the wooden deck requires board replacement, the roofers will manage that project first. The roofers then prepare to build the framing, which may involve the use of prebuilt trusses. Some companies choose to construct the framing by hand on site.
The next step is to start sheathing the new framing. This is done with exterior grade plywood that has been treated to resist moisture and insect infestations. The waterproof barrier and felted underlay are then installed with the use of roofing staples. These materials must cover the wooden decking from edge to edge, with an overlap between pieces of felt. If the homeowner wants any rooftop insulation installed, it will be put on at this point in the project.
Once the surface is prepared, the tiles or shingles will be installed, starting at the bottom of the roof and working up. The roofers will place the metal flashing as they move along. Any necessary sealants or rooftop accessories such as rubber vent collars, vent caps or ridge caps are added at this time. The final step is the addition of gutters and downspouts if these were not already attached to the roof.
