Lean To shed roofs develop an interesting problem as they get larger. If the roof pitch is very steep at all then it will rise to a height that becomes unsightly. Some may say it is ugly. This "ugly" design is most often avoided by installing a low slope roof to keep the rise of the roof at a minimum. The problem with low slope roofs is that they are more likely to leak because of the water does not run off them as fast as when they are built with steeper pitches.

Before you build a lean to shed it is wise to get a better understanding of the different roofing materials and how they can be used to cover your lean to shed without the fear of a leaks.

Asphalt Shingle

The three tab asphalt shingle is arguably the most popular
roofing material because of its low cost and relative good looks for the cost. Asphalt shingles typically have a minimum slope rating of 4 in 12. This means that for every 12 inches of horizontal distance across the shed the roof will rise 4 inches. This slope works well for sheds that are fairly narrow, like 4 to 6 feet, but for sheds that are 8' or wider the shed roof becomes unsightly high. For instance if the top of the wall starts at 8 feet high it will be almost 11 feet high on the high side of the shed.

Metal

Metal roofing comes in various profiles and each profile is rated for a different roof slope. The profile is the way the bends are made in the metal pieces to both give the roofing rigidity and allow it to be installed and connected to adjacent pieces without leaking.

Solutions for Lean To Sheds


Both the asphalt shingles and metal roofs can be installed on a low slope lean to shed roof if the proper product is used and it is installed properly. Regular asphalt shingles that are rated for 4 in 12 roof slopes can be installed on lower slope roofs by simply installing a waterproof membrane under them. This membrane can be a self adhering base sheet or a mineral surface roll
roofing. These roll products create a waterproof layer that the asphalt shingles are installed on top of. One of the best metal roof profiles that is designed for use on low slope roofs is the PBR profile. Different manufactures have different ratings for the PBR design but most are around 1 in 12. It is a commercial rated roofing panel and works well for lean to shed roofs.

Lean To Shed Roof Design


Designing a lean to shed so that it can work with either a low slope metal panel or a modified asphalt shingle installation is done by making the slope 2 in 12. This allow the builder to install either panel no matter what the choice of roofing material is.

Using one of these two materials and application techniques will allow you to have a lean to shed and keep the roof height down so your neighbors don't wonder where the sun went. By understanding how lean to shed plans can detail the proper design to facilitate a low slope material installation you will be able to build a shed that is both pleasing to look at and very functional.

Despite what appears to be high demand for green roofs and green roofing products, there is quite a lack of change going on in America. Compared to other nations around the globe, America still lacks quite a bit of knowledge and motivation to make green roofing the new norm. With so many benefits the discrepancy between national markets is puzzling at best. However, some cultural and industrial differences may be able to shed some light on the gap.

Historical Differences

When we think of green roofing, many of us think solar panels. In fact, a truly "green roof" is one that is made up of vegetation and earth friendly materials. Homes in European and African countries have utilized green roofs for centuries. Made up of grass, flowers or clay, many of these historical homes have been using this roofing technology since the beginning. Perhaps the best thing about this type of roofing is its little need for improvement or modernization. This roof material is highly energy conserving and reduces the need for manufactured materials. Historical roofers had no idea that their limited materials would prove to be such a highly efficient roof, providing better insulation in cold months and reflecting heat in the winter months.

The United States has always lacked a sense of historical appreciation or preservation. Built for the purposes of advancement and growth, the U.S. has aimed to be the main developer of the "bigger and better". Armed with that mindset the pilgrims set to establish a new colony, one that would bring about advanced materials and way of life. Since the beginning, America has fought hard to carve itself a place in the industrial era and manufacturing businesses. With better tools came better manufacturing process, followed by better materials. From weapons to electronics to roofing products, the trends have all followed the same path. But are these advanced materials really "better"?

A Way Of Life

Besides the historical differences in societies around the globe are cultural differences. Those who grew up with green roofs have always known their benefits and rarely experienced anything else. Even in European and African countries where these roofs are common, many have been exposed to modern buildings with modern materials. While they may not debate the modern materials ability to perform their roof-ly duties, there is still the underlying sense of environmental responsibility.

In areas like America, many people never think twice about their carbon footprint or what they are doing to impact the environment. In fact, green roofing is still a very new concept to most Americans, one that is going to require much attention and nurture if it is ever to catch on. The good news is that, despite the fast paced and constantly advancing way of life, many Americans have been exposed to green roofing efforts already. Urban areas are becoming increasingly popular for roof gardens and farms, an idea that is catching the interest of many.

Today there are many attractive, eco-friendly roofs available that are also affordable and fit most home renovation budgets. Here are several different types of eco-friendly options, along with some valuable information about how to choose the best materials for any project.

Different Types of Eco-Friendly Roofing

There are several varieties of products available that promote saving trees and the environment as a whole. These range from shingles made from recycled plastic to those that are made from recycled metal.

Recycled Shingles- Considered one of the greenest and most popular types of roofing materials, recycled shingles are made from waste substances such as rubber, wood fiber, or plastic. Besides being durable, this product has such a pleasing presentation that it is not in any way obvious that it's made from raw waste matter.

Wood Shingles and Shakes- This roofing material has proven exceptionally popular with many homeowners and contractors. Wood shingles usually take less energy to produce; however, conventional wood shingles are made from western cedar trees which have taken a long time to grow in comparison to other types of lumber. Besides not being sustainable in the long run, they are combustible. The use of such a component is prohibited in areas where there is a high risk of forest fires. On the other hand, there are wood shingles made from reclaimed bridges, mills, and other sources of old wood found throughout the country. These materials are processed locally by manufacturers to help reduce energy in the cost of transportation.

Slate and Clay Tiles- When it comes to durability, slate tiles can outlive most people. Slate tiles are best when purchased from a manufacturer that recycles used slate and clay tiles. Clay tiles do not last long when compared to slate tiles that can last for almost a century.

Metal roofing- Metal roofing offers not only exceptional durability but is also fire-resistant. Because of its longer lifespan, it will not have to be replaced as often. This translates to a decrease in the need for materials and a great amount of savings in the long run.

Two Key Dimensions in Eco-Friendly Roofing

Materials and color are the two key dimensions that are very important when considering the best eco-friendly roofing.

Materials- A roof is the final layer of protection against outdoor elements penetrating the inside of a home and preventing indoor heated or cooled air from escaping. Therefore, choosing roofing supplies that have a high performance level, along with the installation of good insulation, will really keep a home at the desired temperature during any season. It is important to consider several aspects of different types before deciding what is the most environmentally friendly. These aspects include: source and composition of the raw materials; maintenance requirements; durability; method of disposal; and its ability to be recycled. Cost and installation procedures are two factors that should be taken into consideration even though they are not necessarily "green" attributes.

Color- Surprisingly, the color of the roof can have a large effect on whether heat is reflected or absorbed into the structure. To reflect heat away from the house, the use of light-colored substances is recommended since they are considered to have high solar reflecting capability. It means that it not only helps reduce the outdoor temperature of the component but also reduces the heat transferred into a house. Dark-colored substances not only absorb heat but also contribute to raising the temperature indoors. If a home is located in an area where the weather is normally cold, dark-colored components are the best choice since it captures more heat from the sun. If the home is located in an area that experiences high temperatures most of the time, light-colored materials would be advised to stay relatively cool.

It is recommended that in order to get advice about the wide variety of roofing options available in green materials, the buyer should speak with a 'green' builder who is familiar with the Energy Star standards. Any buyer who wants to be eco-friendly should look for the best materials available for their needs locally and take the opportunity to help preserve the environment for future generations!

Money spent on roof repairs is not an expense, but rather an investment. A good roof job can last a home between 20 an 30 years. With this is in mind it is important to approach the process diligently and effectively. Ultimately,

The decision to repair a roof can be boiled down into two steps. First, becoming an informed consumer. Second, using the acquired information to select the best contractor for the job.

Step 1: Becoming Informed

Becoming an informed consumer requires understanding that there are a great number of decisions to be made in the roof repair process. To make the choice that best suits the households needs and constraints, it is critical to know what options are out there.

First, it is important to learn about the types of materials available for the project. Used on about 90% of houses asphalt shingles are, by far, the most commonly used roofing for residential properties. These provide a durable, long lasting and economical option. Commercial properties, on the other hand, generally favor decorative stone or mopped tar. This is also very durable material, though slightly more expensive. The one stipulation to the durability of each of these options is that they good care and periodic maintenance.

Although these are by far the most popular options, other choices include metal, terracotta and slate stone. Metal, is a relatively new material that offers a great durability at a significantly higher cost. This cost must be calculated with the consideration that metal roofs typically last as long as the house to which it is connected. They also require little to no maintenance. Terracotta, or clay tiles, can offer a very attractive appearance. If purchased with concrete fiber they can offer a reasonable durability. Slate stone is known for its longevity and aesthetics. Though they require very little maintenance they are the most expensive option.

Step 2: Choosing the Contractor

After having some understanding of the options out there, homeowners are ready to begin the search for a contractor. Along with selecting the right material, this is the most important decision to be made in the entire process. It can even be argued that this is of greater importance, as a good contractor will steer his or her client towards the best material option.

When choosing among contractors it is prudent to follow several guidelines. First, always perform a background check. Determining the number of jobs a contractor has previously performed and questioning former clients about their satisfaction is one of the best proxies for experience. Second, understanding the contractor's insurance coverage can have great implications in the event of an accident. Choosing contractors with the most coverage translates into less risk for the homeowner. Third, making sure the contractor offers at least a ten year warranty is essential. As part of that warranty periodic maintenance and inspection should be included. Ideally each house should be inspected twice a year. Finally, obtaining at least three quotes from three different contractors is crucial. This step not only allows the homeowner to price shop, but also pits contractors against each other, ensuring the best deal possible.

Installing a slate roof requires specific knowledge and skills but by following some basic rules and avoiding common mistakes slate roofing is also within the capabilities of non-professionals. To do it correctly, you should adopt the following practices:

1. General working practices

Do not walk on the slates during installation. Always work off roof ladders and roof scaffolds. This is to avoid slipping slates, i.e. slates that break or fall off after installation.

Chalk your slate courses. install every course along a permanent chalk line on the surface of the roof. Do not chalk on the slates themselves. The lines mark the top edges of the slates. Measure where to put your line from the bottom of the roof to ensure accuracy and consistency. Don't lay the slates without chalk lines as you can easily lose your headlap and ruin the roof.

2. Starter course

The starter course is one of the most important courses on a slate roof and you must install it correctly. First, nail a wooden or copper cant or shim under the bottom edge of the starter course. This will tilt the starter course so that it is at the same angle as all other slates. Then install the starter course with the slate face down and the back up. The starter course is the only course that is installed this way. All other slates are installed with the face up, exposing the bevelled edges.

install the starter course and the first course of field slates at the same time. Do not run the starter course ahead of the first course unless your starter slates are the same width as the field slates and only have nail holes on the top edge. This way you will have correct side laps and ensured that no nail holes in the starter slates in the joint between the first course slates can create a leak.

3. Side laps

Make sure you create the correct side slaps, i.e. the lateral overlaps between the side butts of the starter slates and the first course of slates. The side laps should be a minimum of 8 cm.

4. Head lap

Every slate must overlap the two courses below and you have to ensure that you install the correct head lap. Head lap keeps the roof watertight. If you get it wrong your roof will leak. The head lap for 8:12 and steeper sloped roofs is 8 cm. If your roof has a low slope (4:12 or 6:12) the head lap needs to be 10cm.

5. Underlay

Slate underlay should always be installed under the slates and never on top.

6. Ice-damming

Slate roofs do not need an ice and water membrane. If you're concerned about ice-damming, double the decking felt along the eaves. You can spread roof cement between the layers and increase the head lap along the eaves to 13cm.

7. Slate nailing

You have to get your nailing technique right or you will cause damage to the slates. Nails should only be driven to a depth where the nail head lies within the counter-sunk nail hole crater. Doing it correctly will ensure that the nail heads will not rub excessively against the overlying slates and wear a hole in them.

Do not over-nail or under-nail the slates. Over-nailing means the nail is driven too far and breaks through the slate, leaving it hanging on one nail or sliding out altogether. When the nail is sticking out of the nail hole this is known as under-nailing.

8. Flashings

You have to install flashings with the correct overlap or they will leak. Uphill flashing should always lap on top of downhill flashing. Corner flashings, e.g. chimneys, must either be correctly folded or soldered to prevent leakage.

Folded flashings can be used on positive slopes whereas soldered flashings are required when the slope is so low that the direction of the water flow cannot be controlled by gravity alone. Soldered flashings must be installed with cleats or expansion joints to prevent strain on the solder joints. Never solder with an open flame.

9. Hips and ridges

Make sure the field slates meet tight at the roof hip and form a straight, weather tight, close-mitred junction or install ridge tiles laid to a true line with the edges and joints solidly bedded in mortar. Alternatively, you can use metal roll on the hips and ridges.

installing a slate roof maybe slightly more difficult than installing other types of roofs. By following the advice above you greatly increase the chances of successfully installing a slate roof on your home.

When considering a new roof system, it may be helpful to understand the different types of roofing materials that are available. It is also a good idea to take maintenance costs in consideration, and not simply purchase based on upfront price alone. Many materials also come in a variety of color options that can be very aesthetically pleasing.

Asphalt shingles are one of the least expensive options when it comes to roofing materials. Although they require very little maintenance, they also have a shorter life expectancy than other materials. In most cases, when asphalt shingles have reached the end of their life expectancy, it is necessary to replace the entire roof.

Wood options include shingles and shakes. This type of material requires a lot of maintenance, but can also be a beautiful addition to a traditional style home. They are generally more expensive than asphalt shingles, but can last up to 50 years if they are maintained properly.

Metal roofs range from aluminum to copper to steel and can be a very energy-efficient option. They are usually available in a variety of colors, and can also be molded to look like shingles or shakes. They are very durable, and are also weather and fade resistant. They are less expensive than wood, and have a life expectancy of over 50 years.

Slate tiles come in a wide variety of colors, and are very durable. In fact, most slate roofs can last for over 100 years. One thing to keep in mind; however, is that these tiles are extremely heavy, and must have the proper support structure. They can be very expensive to install, and the individual tiles are very fragile.

Clay tiles are also a very heavy option that requires the right type of structure, but can be very aesthetically pleasing on homes that have a particular style, such as Spanish or Italian. Although clay tiles can be an expensive option, it is fire and weather resistant.

An eco-friendly option would be a green roof. Although this will depend on the slope of the roof, green roofs can offer many benefits if they are properly installed and maintained. These are known to improve air quality, and increase biodiversity, and some people have designed entertainment areas, or grown their own food on a green roof, which also makes it a dual purpose option. Green roofs can be an expensive option, and can require a great deal of maintenance. There is also a specific layering process that should take place when installing a green roof. Obviously, this is a more involved process, but there can be several benefits associated with installing a green roof.

When exploring the different types of roofing materials that are available, it is important to remember that the structure and style of the home can often be a factor. There are many alternatives that may be more expensive in the beginning, but also offer a larger variety of color and style choices that can last for a very long time. It may also be a good idea to speak with a professional roofing company to see which options would be the best solution for a particular home or building.
