Single-Ply Roofing:

Single-ply roofing systems (SPS) have grown in popularity over the past 30 years as a preferred commercial roofing system, due to their ability to provide strength, flexibility, and long-lasting durability, it’s no wonder that architects, roofing contractors and building owners love this product. SPS membranes are strong, flexible sheets composed predominately of synthetic polymer manufactured to strict quality control requirements. Advantages of pre-fabricated sheets include the consistency of the quality of the membrane and accessories, and versatility in their attachment methods that may be used on a variety of commercial building applications.

SPS provides maximum freedom of choice in roof design, performance and appearance to suit new construction and refurbishment. In addition to providing a durable and watertight membrane roofing system, many SPS sheets are furnished from the factory with a highly-reflective “cool roof” surface that becomes part of an energy efficient building envelope system. Cool roof systems reflect rays of the sun, reducing building cooling costs.

Benefits of Single-ply Roofing:

•  Proven track record of performance. 


• A broad range of application methods available as part of a “Class A” fire-rated roofing system


• With insulation, provides an even better-performing building component


• Wide choice of top-coatings, including “Cool Roofing” options


• Superior waterproofing characteristics


• High tensile-strength


• Competitive life-cycle cost


• Long-term warranties are available with many SPS systems.

Built up Roofing:

Built-Up Roofing (BUR) is one of the oldest and most reliable commercial roofing systems for buildings with low-slope or “flat” roof structures. Started in the 1840's, these roof systems are often referred to as "tar and gravel" roofs. BUR consists of multiple plies of roof felts  laminated together with bitumen. BUR consists of bitumen-saturated organic-fiber, fiberglass, or polyester felt. A top-surfacing or a glaze coat of asphalt, aggregate (gravel or slag), fibered, or non-fibered coatings engineered for roof coating, or a granule-surfaced cap sheet. BUR may be designed and specified to meet a broad range of building waterproofing applications, depending on the needs of the building owner. These systems range from very basic systems designed to be vigorously maintained to upper-end systems that are constructed to qualify for a manufacturer’s warranty. Roofing manufacturers, working in close coordination with Evans Services, will write long-term warranties for building owners based on specific design criteria. Some warranties even qualify for decades of “full-value” labor and materials coverage.

Evans Services, commercial roofing specialists can furnish you with more details. Over the years, BUR has earned a great reputation with building owners, architects, engineers, roofing product manufacturers and commercial roofing contractors. The original cost of a BUR system may be greater than other low-slope applications, but when taking the long view, BUR often comes out a winner. BUR enjoys a track record that is over 150 years old, provides a thick, durable roof covering, may be used in a broad range of building waterproofing applications, and after many years of service may be maintained and repaired for extended life (many other systems must be completely replaced).

Benefits of Built Up Roofing:

• Proven track record of performance


• Broad range of application methods


• Available as part of a fire, wind, and/or hail rated roofing system


• Wide choice of top-surfacing, including “Cool Roofing” options


• With insulation, provides an even better-performing building component

Composition Shingle:

By far and away the number one covering over the steep-sloped roofs of the United States and Canada are asphalt shingles. Developed over a century ago, asphalt shingles have proven to be one of the most cost-effective solutions for commercial applications. Organic shingles made with a base of wood fiber and asphalt have given way to fiberglass reinforced shingles which dominate the market today. These shingles offer the homeowner many choices of colors and textures, as well as length of warranty for the right mix of durability, appearance and affordability. Used in many steep-slope commercial roofing applications, asphalt shingles are available in a tremendous range of colors and styles. Designers, builders and owners have literally hundreds of asphalt shingle products to choose from. Asphalt shingles are available in a basic “three-tab” design; the middle-range “dimensional” or “laminated” shingle (most popular option in new home construction); and the “top-of-the-line” heavyweight shingles.  Noted for their low cost and ease of application, asphalt shingles continue to be popular due to their great look. No matter the architectural or style requirement, there is an asphalt shingle produced that will fit in very nicely.

Benefits of Shingle Roofing

• Available in a wide variety of dimensional styles, sizes, and thicknesses


• Available in dozens of designer colors


• Available with granules resistant to algae and fungus


• Water repellent Durable and very long-lasting

Attic Ventilation:

Ventilation of the home attic is important for two reasons. During the summer, excess heat that builds up in the attic during the day results in high energy costs for cooling. Also, moisture produced within the home may move into the attic if ceiling vapor barriers are not used. If this moisture is not exhausted from the attic it can condense and cause insulation and construction materials to deteriorate. Thus, temperature and moisture control are the major reasons for providing attic ventilation.  

Attic ventilation is almost always passive in nature, and relies on convective air flow, where cooler air is drawn into soffit vents along the eaves and rises through the attic and passes out the roof vents on top. Both soffit and roof vents can easily become blocked, and should be inspected on a regular basis.

The recommended minimum attic ventilation rate is one square foot of roof ventilation (one typical roof vent provides approximately one square foot of ventilation) for every 150-200 square feet of attic space. . .remember, as far as attic venting is concerned more is almost always better!

The Benefits of Roof Ventilation

• Allows outside air to flow naturally upward and out of attic
• Promotes a cooler, drier attic
• Helps prevent moisture from becoming trapped in insulation, structural wood, shingles and roof deck
• Helps prevent rotting, mildew, drywall damage, peeling paint and warped siding
• Provides year-round performance for consistent ventilation without energy consumption
  

TYPES OF VENTILATION:

RIDGE VENTS:   In winter, normal household activities like doing laundry, running dishwashers and taking showers generate moisture that can damage insulation, rafters, wood deck, underlayment and shingles. In summer, heat build-up can cause premature aging and cracking of wood and roofing materials.The only way to combat these problems is with balanced ventilation. When a ventilation system is balanced, wind blowing over the ridge creates a negative pressure that draws the warmer air out of the attic. Replacement air enters through the under eave vents, bathes the underside of the roof, and exits at the ridge cap.     Even with no wind, the natural convection action of rising warm air maintains a continuous flow along the underside of the roof.  It's a system that works year 'round with no moving parts or energy consumption.

TURBINES:  A non-electric alternative to ventilation, these vents use the natural force of wind and air pressure to spin and vent out stale attic air.  They do it with a series of specially shaped vanes that catch the wind and provide rotary motion.  This pulls hot, humid air from the attic.  Turbine vents provide a low-cost ventilation alternative in areas where wind speeds of at least 5 mph are typical.

Seamless gutters:

Seamless gutters are the most popular type today. The biggest selling point is that they don’t have any seams which could potentially leak. The sections join only at inside and outside corners and at downspout outlets. Seamless gutters are usually formed from aluminum that has a baked-on finish, but they may be made from copper or factory-painted steel. They are made with a special machine that's brought to your home by a gutter contractor. These types of gutters can not be installed by do-it-yourselfers.

Vinyl siding:

Vinyl Siding is the number-one siding material available. No other exterior home improvement beats Vinyl Siding for its many resilient qualities. Vinyl is a sealed surface that rain, cold, salt and snow cannot penetrate.

Vinyl siding is a great way to beautify the exterior of your house. You will find that vinyl siding provides flexibility and endless selection. There are many varieties, styles, colors, and accessories to choose from. You will find siding that will flow perfectly into your home's design.   It is extremely low maintenance and easy to maintain. It will even act as a layer of insulation against heat and cold weather.

Vinyl siding is a great way to give your house many years of virtually maintenance free good looks!

The Benefits of Vinyl Siding:

• Performance - durable construction means it resists dents and damage from hail and harsh weather.
• Beauty - vinyl siding gives you that attractive freshly painted look that maintains its beauty year after year.
• Low maintenance - caring for your vinyl siding is nothing more than an occasional spray with the garden hose.

Skylights:

If you had to choose one word to define a room with a skylight, a good word might be dramatic. The benefits of natural light to people and houseplants are well known. Skylights provide more natural light than vertical windows (up to 30%). From a design perspective, they can actually make a room feel bigger. Skylights are available for any ceiling or roof style.

Radiant Barrier Insulation:

Radiant barriers are installed in homes—most commonly in attics—to reduce summer heat gain and winter heat loss, which helps lower heating and cooling costs. The barriers consist of a highly reflective material that reflects radiant heat rather than absorbing it. They don't, however, reduce heat conduction like thermal insulation materials.

How They Work

Heat travels from a warm area to a cool area by a combination of conduction, convection, and radiation. Heat flows by conduction from a hotter location within a material or assembly to a colder location. Heat transfer by convection occurs when a liquid or gas is heated by a surface, becomes less dense, and rises (natural convection), or when a moving stream of air absorbs heat from a warmer surface (forced convection). Radiant heat travels in a straight line away from any surface and heats anything solid that absorbs the incident energy. Radiant heat transfer occurs because warmer surfaces emit more radiation than cooler surfaces. When the sun heats a roof, it's primarily the sun's radiant energy that makes the roof hot. A large portion of this heat travels by conduction through the roofing materials to the attic side of the roof. The hot roof material then radiates its gained heat energy onto the cooler attic surfaces, including the air ducts and the attic floor. A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic.

A radiant barrier's performance is determined by three factors:

• Emissivity (or emittance) – the ratio of the radiant energy (heat) leaving (being emitted by) a surface to that of a black body at the same temperature and with the same area. It's expressed as a number a between 0 and 1. The higher the number, the greater the emitted radiation.


• Reflectivity (or reflectance) – a measure of how much radiant heat is reflected by a material. It's also expressed as a number between 0 and 1 (sometimes, it is given as a percentage between 0 and 100%). The higher the number, the greater the reflectivity.


• The angle the incident radiation strikes the surface—a right angle (perpendicular) usually works best.

All radiant barriers must have a low emissivity (0.1 or less) and high reflectivity (0.9 or more). From one brand of radiant barrier to another, the reflectivity and emissivity are usually so similar that it makes little difference as far as thermal performance. (Most products have emissivities of 0.03–0.05, which generally corresponds to a reflectivity of 95%–97%.) Also, the greater the temperature difference between the sides of the radiant barrier material, the greater the benefits a radiant barrier can offer.

Radiant barriers are more effective in hot climates than in cool climates, especially when cooling air ducts are located in the attic. Some studies show that radiant barriers can lower cooling costs between 5%–10% when used in a warm, sunny climate. The reduced heat gain may even allow for a smaller air conditioning system. But in cool climates, it's usually more cost effective to install more than the minimum recommended level of insulation rather than a radiant barrier.

Types of Radiant Barriers

Radiant barriers come in a variety of forms, including reflective foil, reflective metal roof shingles, reflective laminated roof sheathing, and even reflective chips, which can be applied over loose-fill insulation . The reflective material, usually aluminum, is applied to one or both sides of a number of substrate materials. Substrate materials include kraft paper, plastic films, cardboard, oriented strand board, and air infiltration barrier material . Some products are fiber-reinforced to increase the durability and ease of handling.

Also, radiant barriers—which don't provide a significant amount of thermal insulation—can be combined with many types of insulation materials. These combinations are called reflective insulation systems . In these combinations, radiant barriers can also act as the insulation's facing material .

Installation

Radiant barriers can be installed between the roof sheathing and attic floor insulation, in cavity walls, and around door openings, water heaters, and pipes. It's easier to incorporate radiant barriers into a new home, but you can install them in an existing home too.

An installer typically drapes a rolled-foil radiant barrier foil-face down between the roof rafters to minimize dust accumulation on the reflective faces (double-faced radiant barriers are available). This is generally done just before the roof sheathing goes on if it's not too windy, but it can also be done afterwards from inside the attic by stapling it to the bottom of the rafters.

When installing a foil-type barrier, it's important to allow the material to "droop" between the attachment points to make at least a 1.0 inch (2.5 cm) air space between it and the bottom of the roof. This air space has mainly two functions: it creates an air channel for the soffit and ridge ventilation system to work more effectively, and it acts as a second reflector since there are two shiny sides (one facing up/ one facing down.)

Some builders also try to attach the radiant barrier directly onto the roof sheathing prior to their installation on the roof rafters. However, a more effective method is to simply buy foil-faced plywood or oriented strand board sheathing instead. There are also metal roof shingles that have a reflective underside. If you need roof shingles, these are a practical option, but the cost of this type of radiant barrier is considerably higher than other types.

A radiant barrier installed on top of attic floor insulation is more susceptible to dust accumulation. This undesirable installation method may also trap moisture in fiber insulation during cold weather. A radiant barrier installed on the cold side of the insulation acts as a vapor barrier in the wrong location. When warm moisture carrying house air leaks into the attic in the winter, it may condense on the underside of the barrier. Even a perforated radiant barrier can trap moisture in cold climates since the water can freeze in the small holes and seal them. Because of these hazards, it's strongly recommended that you NOT apply radiant barriers directly on top of the attic floor insulation. Of course, installing them at all in a cold climate is not generally cost effective anyway.

A radiant barrier's effectiveness depends on proper installation. Therefore, it's best to have a certified installer do it.  Evans Services is experienced in installation of radiant barriers and is familiar with the local building and fire codes for installation of same.
