Woodstock Green Roofer

A green roof in Woodstock is known by several names such as ecoroof or living roof. They have been built on buildings for centuries. Many countries in the world have green roof subsidies or programs that encourage ecoroofs. Scandinavia has long had farm house buildings that have sod covered roofs. Some cities in the US are known for their living roofs such as Chicago’s City Hall building.

Basically a green roof is a roof that has vegetation and a growing medium. It will cost more than a standard asphalt shingle roofing application. Rooftop garden costs also depend on the type of green roof installed. There are several differences among green roofs in Woodstock and some applications that may or may not be defined as a green roof such as a container garden green roof.

What Is Green Roofing?

Flat Roofing - Why are they so popular?

Gone are the days when roofs for buildings used to be made from easily available materials like thatch or straw. These days, the best of technology and latest advances combine to make roofs durable and more resilient in nature. Although it's easy to think that a roof is not as important as the main structure of the building itself; that is a mistake because a good roof will help protect from the elements and last for years to come. There are different roof types with unique characteristics such as a gable (which is triangular in shape), a mansard (found in many French houses), a shed (which allows rain or snow to run off easily) or even roofs with a combination of two or more designs. The materials used to make roofs are sturdier in nature and are designed to look natural yet stylish. Slate, concrete tiles and even metal are some of the most common options today.

Features of a Flat Roof

A flat roof is almost perfectly horizontal in design but usually has a slight slope so that snow and water can drain off easily. They are very easy to build and have been around for centuries. Initially, gravel and tar were used to contain leakages caused by stagnant water which accumulated on the roof. This kind of roof posed a bigger problem in cold climates as most owners had to deal with small collected pools of water, which invariably caused terrible leakages. These days, flat roofs are made from various materials which are usually a combination of synthetic rubber and polymers. They suit residential buildings better in comparison to commercial buildings, as they can become unstable when the size of the building is considerable. They also tend to be sensitive to large amounts of activity as they may develop cracks easily.

The Pros and the Cons

Unlike most other roofs which are not really cost-effective, flat roofs help minimize installation time, last longer, are easier to maintain, are inexpensive and have been proven to handle weather fluctuations extremely well. In addition, these roofs offer certain flexibility and are easier to clean than a sloping roof. If you would prefer to add a few decorative finishes or even a terrace garden, you can do that with a flat roof. Installing one is also believed to increase the value of your home. On the other hand, all buildings are not suitable for a flat roof and most coatings for these roofs may not be long lasting either. In this context, these roofs may require periodic maintenance to extend the life of the roof itself. The best way to find out if your home or commercial building is ideal for a flat roof is to consult your architect or a roofing expert for advice.

Eco-Homes: Why Durable Zinc Is the "Green" Solution for Residential Roofs

Sustainable, or "green," buildings - buildings that are deliberately designed to use natural resources in a way that's environmentally friendly -- are no longer a luxury. They are an imperative.

Consider the facts: According to the National Institute of Building Sciences' Whole Building Design Guide, "On an annual basis, buildings in the United States consume 39 percent of America's energy and 68 percent of its electricity. Furthermore, buildings emit 38 percent of the carbon dioxide (the primary greenhouse gas associated with climate change), 49 percent of the sulfur dioxide, and 25 percent of the nitrogen oxides found in the air. Currently, the vast majority of this energy is produced from non-renewable, fossil fuel resources..."

Of the two ways to reduce heating, cooling and lighting loads "through climate-responsive design and construction practices," the Whole Building Design Guide recommends the use of "high-performance building envelopes: select walls, roofs, and other assemblies based on long-term insulation, and durability requirements."

One of the most sustainable, high performance building materials prevalent throughout the world is zinc.

Zinc is reported to be the 23rd most abundant element in the earth's crust. It is a non-ferrous metal that is not susceptible to rust or corrosion: It's weatherproof, seismic proof, corrosion resistant, and immune to the harmful effects of UV rays, ensuring a very long service life without degradation.

This is possible because architectural zinc develops its own protective layer, which is called zinc hydroxyl carbonate. Once it's formed, that layer blocks moisture and chemicals from penetrating the zinc and, if it's scratched, the hydroxyl carbonate will reform over time. In other words, zinc heals itself. That's why zinc walls and roofs last on average from 80 to 100 years.

Zinc also requires very little energy to manufacture and little to no maintenance, and it is 100 percent recyclable from new construction scrap to the time it reaches its end use. As a result, zinc roofs and wall cladding never end up in landfills.

For generations, European architects have specified zinc as a building envelope material for all types of buildings because it would last and endure harsh weather conditions. In the late 1700s, zinc was also one of the most popular materials used for roofing in America, which is why many well-known historic structures, such as the Washington Monument and Thomas Jefferson's Monticello, had metal roofs.

Unfortunately, zinc fell out of favor in the U.S. as less expensive roofing materials evolved, such as asphalt shingles, and as American developers and building owners lapsed into a "throw-away" mind-set in the 1960s and '70s that still assumes no more than a 30- to 50-year life span for American buildings.

Today, American architects are becoming more enamored with the material, not only for its durability but also because of the increasing need for environmentally sustainable design and construction.

American architects are warming to the use of zinc on commercial, institutional, and government buildings. A few far-sighted practitioners are also encouraging their residential clients to use architectural zinc on their homes - from brand-new construction to renovation and historic restoration.

New Construction: Thinking of The Future

"Zinc ultimately costs much less than asphalt shingles when you calculate the life span of the house," says Daniel Nicely, director of market development for VMZINC and an associate member of the American Institute of Architects (AIA). "Shingles are usually composed of asphalt, a decidedly non-green material, and an average shingle roof will need to be replaced about every 10 years -- four to five times compared to the lifetime of one zinc roof."

The value of zinc's low maintenance factor was underscored at the University of North Carolina at Greensboro when the decision was made to use zinc for two projects there, including the Hall for Humanities Research and Administration. The university acknowledged that construction budgets tend to be well funded but maintenance budgets are not. The self-healing characteristic of zinc was another factor in the decision, as was aesthetics:

"Zinc worked well because of the appearance," said Andy Sykes of Calloway Johnson Moore & West, PA, in North Carolina, project manager for the Hall for Humanities' project. "The color was more similar to what historical turn-coated lead roofs looked like and blended with the traditional campus roofs." (source: McGraw-Hill Construction, Continuing Education Center)

The aesthetic quality of architectural zinc for historic buildings was a key issue for the Central Presbyterian Church in Huntsville, Alabama, when it renovated the Cooper House, a nearby antebellum house that is listed on the National Register of Historic Places, to become its new Family Life Center. The old house needed a new roof and rainwater system that would be consistent with the house's historic style and last well into the future.

Hays Buchanan, the architects on the church project, chose natural VMZINC "for its historically correct gray color, strength and durability," reported Design & Build With Metal.com recently.

While zinc is often used in contemporary applications, the Cooper House project is a perfect example of why it is is a natural choice for historic restoration: the color, in this case of natural VMZINC, is historically correct aesthetically pleasing, durable and intended to last for decades. In addition, production techniques allow it to maintain the unique look of natural metal with consistent colors. Natural VMZINC will not develop a drastically different patina like copper, for example, that changes from its copper color to green. Instead, it weathers over the years to form a textured gray patina.

Design and Build with Metal.com also reported that Central Presbyterian church leaders and the Huntsville/Madison County Historical Society "readily approved the application [of zinc roofing and rainwater system] as consistent with the building's historical architecture."

Will Residential Use of Zinc Sweep America?

After rhapsodizing over the beauty, value, and sustainability of architectural zinc, Dallas architect Bob Borson answered the question he knew his blog readers would ask: Why isn't zinc used more in residential design?

"The reason we don't use it more often is because of the price," Borson wrote. "For the average standing seam profile, material cost and labor will run you in the ballpark of $20 per square foot."

For a young family building their first home, or senior citizens replacing the roof of a home they've already lived in for over 50 years, the cost is understandably prohibitive. But for new, modern homes from North Carolina to California, elegant estates in the North East or Pacific Northwest, a mid-century or old farmhouse renovation in Florida or Kentucky, or a historic home in heart of Charleston, Savannah, New Orleans' French Quarter, et al, the durability and sheer beauty of zinc roofing and wall cladding will continue to gain popularity as the imperative for sustainable, energy-saving homes grows stronger.
