Insulation

According to the US Department of Energy, up to 45% of a home's energy loss is through the attic. Westshore Roofing, Inc. will inspect the insulation in your attic, to see if it meets the levels recommended for your area. Insulation is measured in R-values—the higher the R-value, the better your roof will resist the transfer of heat. The Department of Energy recommends ranges of R-values based on local heating and cooling costs and climate conditions in different areas of the nation. The Department of Energy recommendations for the Bay Area is a minimum of R30. (11 inches of fiberglass or rock wool or 8 of cellulose. 
Insulating your attic with Owens Corning insulation qualifies you for a tax credit for 10% of the cost of materials for qualifying insulation projects throughout 2015 up to a maximum of $500.00.
A 25% discount is also available from Westshore Roofing, Inc. when installing loose-fill blown in attic fiberglass insulation the same time a new roof is being constructed.

Energy Savings with Cool Metal Roofing
Did you know white-painted metal roofing has the highest solar reflectance value of any roofing product available and can save you up to 40% of your annual energy bills? 
More and more, homeowners are seeking out energy-saving building materials for their renovations and new homes, products that not only secure and improve structures but also provide longterm cost-cutting on energy bills while promoting environmental and economic sustainability in the greater community.
Among the array of possible upgrades, “cool metal roofing” easily answers this consumer demand offering a solid, attractive roofing solution available in multiple colors, textures, and profiles, for steep-slope and low-slope applications, that can save your household up to 40% of its annual energy costs, depending on your geographical region. 
The Benefits of Energy Efficient Metal Roofing
As reported by the Cool Metal Roofing Coalition and the Oak Ridge National Laboratory, installation of reflective metal roofing can save your home up to 40% in summer cooling energy costs while highly emissive metal roofs can reduce urban air temperatures by as much as 12 ° F. Combined, these benefits mean less money out of your wallet, less dependence on energy resources and less general air pollution in your neighborhood and across the nation.

The secret to metal roofing's energy savings is in its variety of finishes. As shown above, the basic, unpainted metal roof will reflect much of the solar radiation usually absorbed in your attic and home by an asphalt roof. But, for homes in warmer climates, pre-painted or granular coated metal roofing systems not only reflect solar energy but also cool your home by re-emitting most of what solar radiation is absorbed. Where annual cooling loads dominate, a highly reflective and highly emissive painted or granular-coated metal roof is optimal for reducing energy consumption and can actually re-emit up to 90% of absorbed solar radiation.
Additionally, most metal roofing, including standing seam, is composed of recycled material and can be installed directly onto an existing asphalt roof, reducing landfill waste and promoting quick installation as well as decades of environmentally-sound, maintenance-free strength and beauty.

Therma Sheet

Therma-Sheet insulation has 99% pure polished aluminum facings. The facings are heat laminated to a closed cell polyethylene foam core. It is installed over top of traditional felt paper or other underlayments. Therma-Sheet provides excellent thermal and moisture protection under metal roofing, stone coated steel, concrete or clay tile. It can also be used under asphalt singles, but the reflective qualities will not be utilized. However, the foam core will create a thermal block and significantly reduce summer heat gain and winter heat loss in the attic.

Ventilation

Venting your attic helps to control extreme temperature swings by creating a balanced system. Of course, a vented attic is cooler on a hot day than an unvented attic. This mediation keeps your home naturally cooler in hot weather and helps conserve your air conditioner’s energy as it attempts to keep the home’s interior comfortable. Avoiding extreme attic heat will also help to extend the life of roofing material, such as shingles, shakes or composite tile.
In addition, attic ventilation reduces the buildup of moisture inside the attic, which can damage your insulation, cause wood to rot, encourage mildew to build up, and can damage any items you have stored in the space. In cold weather, frost inside the attic from moisture buildup can melt and cause damage to insulation and ceilings inside your house. Maintaining proper ventilation keeps your attic dry and stable. 
One method for removing the hot air from your attic is to install a Ridge Vent at the peak of your roof.
Ridge vents are extremely low profile, following your natural roofline, and can even be designed to match your roofing material exactly. Ridge vents also utilize the natural flow of air and rising heat to keep your attic well ventilated, so no power or moving parts are required.

Roof Underlayment

Provided an extra layer of protection between your roofing shingles and roof deck. Traditional underlayments are manufactured with asphalt. These products are black color which easily absorb the heat from the roof shingles. Westshore Roofing, Inc. recommends the use of synthetic underlayment such as Tarco EasyLay UDL 50. These are not only 30x stronger, but can reduce the amount of heat intake into the attic.
Tarco EasyLay UDL 50 also carries a 50 year manufactures warranty and has great water repelling abilities.

Cool Solutions

Cool Asphalt Composition Shingle Roofs

A cool roof is a roofing system that delivers higher solar reflectance (the ability to reflect the visible, infrared and ultraviolet wavelengths of the sun, reducing heat transfer to the building) and higher thermal emittance (the ability to radiate absorbed, or non-reflected solar energy) than standard designed roofing products. Historically, cool roofs have been either white or some other lighter shade color. However, that dynamic has changed in recent years with the development of residential cool roof products that can achieve EnergyStar® qualified levels of solar reflectivity even in dark, rich hues.

Cool roofs can also enhance roof durability and reduce both building cooling loads and the urban heat island effect.

Most of the roofs in the world (including over 90% of the roofs in the United States) are dark-colored. In the heat of the full sun, the surface of a black roof can increase in temperature by more than 100 °F over the ambient temperature, reaching temperatures up to 190 °F. This increase in surface temperature can contribute to:

  • Increased cooling energy use and higher utility bills;  
  • Reduced indoor comfort;  
  • Accelerated deterioration of roofing materials, increased roof maintenance costs, and high levels of roofing waste sent to landfills. 
  •  Higher peak electricity demand (the maximum energy load an electric utility experiences to supply customers instantaneously, generally experienced in summer late afternoons as businesses and residences turn up their air conditioners), raised electricity production costs, and a potentially overburdened power grid;  
  • Increased air pollution due to the intensification of the "heat island effect" 
Any building with a dark colored roof will consume more energy for air conditioning than a “cooler” building – a strain on both operating costs and the electric power grid. Cool roof products offer both immediate and long-term savings in building energy costs. The EPA reports that cool roofs can: 

  • Reduce energy use: A cool roof transfers less heat to the building below, so the building stays cooler and uses less energy for air conditioning. 
  • Reduce air pollution and greenhouse gas emissions: By lowering energy use, cool roofs decrease the production of associated air pollution and greenhouse gas emissions. 
  • Improve human health and comfort: Cool roofs can reduce air temperatures inside buildings with and without air conditioning, helping to prevent heat-related illnesses and deaths.
