Davis Roofing: Article About Roofing Options
Many homeowners are interested in ways to improve their energy efficiency without having to cut back on comforts such as hot showers or air conditioning. One cost effective way of reducing the size of a household's carbon footprint is by installing what Davis roofing professionals and other industry experts refer to as a "cool roof." A cool roof uses a variety of materials to increase the structure's Solar Reflectance Index (SRI). This index ranges from zero to 100, with 100 being a perfectly efficient and environmentally friendly roof. The higher a home's SRI, the less heat is absorbed by the roofing system. This in turn lowers the amount of energy needed to cool the home during the summer months of the year. There are many advantages of increasing the SRI of a home.
The vinyl coating used for SRI enhancement can be applied to the existing roofing structure. The lightweight sheets can help to extend the roof's lifetime. This waterproof barrier also lessens the chance of roofing leaks as well as other problems, such as blown off shingles or tiles.

Less roof maintenance is needed after the vinyl sheeting is installed as there won't be any asphalt granules clean out of the rain gutters or flashing to repair.
Another advantage of increasing a home's SRI is the reduction of household utility bills. During the summertime, homes with a high SRI require less cooling. This is because the vinyl reflects the sun's heat and light back into the atmosphere, rather than absorbing it. Since the air conditioning system cycles fewer times, there is less energy used for keeping the house comfortable. This also works to extend the lifespan of the AC unit, saving even more money on repair and replacement costs.
In urban environments, cool roofing systems help minimize the heat island effect. The heat island effect is a result of the heat emitted by asphalt shingles and roofing tar. Covering these materials with vinyl helps reduce this urban heating effect. The vinyl coating also helps lessen air pollution as heated asphalt and tar leak airborne volatile organic compounds. One time tax credits may also be available when an energy efficient roofing system is used to replace an inefficient one.
Many homeowners find that the installation of a new cool roof saves them money at tax time as well. Local, state and federal government agencies often offer rebates and other tax incentives for the installation of environmentally friendly replacement products.
