In countries, that experiences extreme temperatures, ventilation must be considered when thinking about new roofing replacement. Ventilation is important to maintain the integrity of the roof. Extreme high temperatures will increase energy consumption because air-conditioning systems tends to work twice to meet the cooling setting. On the other hand, ventilation is also important on cold temperatures because moisture will damage wood and metal components in a roof. In more extreme conditions, ice will accumulate on the roof, which will significantly damage the entire roofing material. For this reason, any house built today is encouraged to place any type of ventilation system. This way, modern houses are assured that roofing material’s life span will be extended. Roof contractors are very helpful to attach ventilation system to the roof. However, there are myths concerning roof ventilation that most people find disturbing. Let us go over some of these myths.

Roofing replacement myths

More vents are better – When homeowner think about installing new roofing replacement for old roofs, almost all of them will think that the more vents installed, the better is the ventilation. Just like any other roofing accessory, having the right number of vents is essential for optimum benefits. Too much vents will more or less do the opposite. For instance, in cold season, too much ventilation will allow cold air to enter and creates moisture. On the other hand, air conditioning system inside the house will be sucked up by the vents making them work harder. Ideally, there is a right number of vents depending on the size and width of the roof. In every three hundred square feet of roofing space, it will require one vent.

Ventilation is only beneficial during hot climates – Some people may think that hot air will be vented out during the summer, which leads to a relaxed and cool living space. However, when using air conditioning systems, the cool air will be vented out by the vents. This will in return increase the workload of the air-conditioning systems. Vents are also important during the winter because it keeps moisture away. The benefits of vents during the winter are much better than the benefits it provides during the summer.

Best ventilation systems are those run with electricity – This may be partly true since exhaust fans effectively create a negative air pressure in the room, which allows cold air outside to be sucked inside. However, on larger scale, exhaust fans may not be as effective as it is. Mechanical ventilations are better because hot air rises and escapes through the vent. The continuous rotating motion of mechanical vents will continues to allow hot air to escape and cool air to come in. this is very effective for larger areas because it has higher amount of hot hair rising.

Having the right vents on your new roofing replacement will remarkably offer the best result when it comes to ventilation. To have the best type of vents installed on your roofing replacement, hire a group of experts that can assess and calculate the number of vents that you need for your new roofing replacement.

Promoting ventilation on new roofs is important in maintaining and sustaining the life span of roofs. Adequate roof ventilation promotes a balanced temperature between the inside and outside temperatures. This balanced temperature will keep moisture away and reduces heat inside the house during the summer. Moisture will occur during cold seasons, which will decrease the life span of the woods. Build up of molds will make the woods rot and cause it to collapse. In severe low temperatures, ice build-up will occur which further decreases the life spans of the woods. On the other hand, extreme temperatures will increase electricity bills due to air conditioning systems. These are just some of the risks when ventilation is not installed. Especially on houses located in areas, that suffer severe high and low temperatures, ventilation is very essential. A national building code is implemented to encourage homeowners to install ventilation system on new roofs. This will help homeowners decrease the cost of roofing repair and maintenance. To learn more about roofing ventilation, let us explore the different methods of ventilating systems. Moreover, how they work in removing hot air on new roofs.

How ventilation on new roofs work

Most ventilating systems attached on new roofs work dependently on the intensity of hot air inside the house. With the law of physics, hot air rises because it has lesser density than cold air. It works the same with a hot air balloon, which uses hot air to lift it up. Most ventilating systems are made from metal shaped into a dome with special designs that turns once hot air escapes. It continuously rotates to allow more hot air to escape constantly. There are no motor or any mechanical designs attached to roof ventilators. However, modern ventilation makes use of an exhaust fan to create a negative pressure in the house or attic that pulls outside air in and keeps air circulating inside the house or attic. Air-conditioning systems are also utilized to maintain good ventilation but it cost more energy compared to traditional ventilating methods.

Types of new roofs ventilation systems

Power vents – These types of ventilation system makes use of electricity to run a motor and move inside air out. Exhaust fans and air conditioning systems are examples of power vents. The downside when using this type of ventilation system is it produces noise during operation. In addition, it increases your electric bill dramatically.

Static ventilation systems – Are those found on rooftops that turn continuously. They work when hot hair rises and escapes through the vents. This type of vents is installed together with the roof during construction. It is lightweight and ideal for warehouses because it does work without the help of electricity.

Foundation vents – This maintains home ventilation with a coil that automatically closes and opens the vents depending on the temperature inside the house. The vents open when the inside temperature is rises. It closes when the inside temperature is lower than the outside. This is often installed at the corner of the house or place at the sides of new roofs.

Almost every roof has a predetermined life span and roofing replacement is ideally the only best solution for roofs that has reached its estimated service life span. Although a roof’s life span would depend on some environmental factors such as rain, humidity, climate, location, type of roofing material, roof style and the slopping of the roof. Generally, some homeowners prefer to do roofing replacement with roofs with the same life span. In this way, they won’t be replacing their roof one at a time. The importance of roofing replacement would ensure home owners that they always get a reliable protection against environmental factors that are protected by roofs. A common question by some home owner is when would roofing replacement take place actually? For some, it is not important to wait for your roof to leak or show some indication of wear and tear. Roofing replacement should be done as soon as the roof has reached it ideal life span.

Indications that requires roofing replacement

The indications that the roofs have reached its predetermined life span would vary depending on the type of roofing material. Basically, roofs that are made from stronger materials like metals would last for more than fifty years. On the other hand, roofs made out of asphalt, or wooden shakes or shingles would only last for ten to twenty years in service. The typical roof would ideally last for thirty to fifty years according to the National Roofing Contractors Association. When proper roof maintenance is applied, the need for new roofing replacement would be extended. Roofing maintenance would include a yearly inspection and repainting. Indications that would require roofing replacement would include dents, uncontrollable leaks, severe damage, rust and unfixable cracks. Taking these indications of roofing replacement for granted would lead to catastrophic roof collapse that would endanger the people in the house. That is why, roofing replacement is essential in every roof owner. On the other hand, roofing replacement would require professional care. Roof contractors can be hired to replace a roof that has already served its purpose and requires replacement. In looking for roof contractors, you can visit your local hardware store and they can recommend professional roof contractors who have a wide knowledge regarding home roofs.

Considerations in roofing replacement

Once you have already contacted roof contractors for roofing replacement. Always take into account the type of roof material to be replaced. Make sure to use roofs with the same material and the same life span. Furthermore, always take note on how your rood is installed. Proper overlapping of the roof would ensure tight waterproof ability. Isolating material should also be considered since this would isolate the inside of the house from heat or cold temperature from the outside environment. Although contracting professionals for roofing replacement can be very expensive, it is still worth the pay since doing it yourself can be difficult and might cost more money if don’t do it right. Roofing replacement is just one home maintenance that you need to spend large amount of money for it.

Asphalt Roofing – Roofing Materials

Reasons to Choose Asphalt Roofing Shingles
by Roof101 – Constituting about 80% of roofs in America, asphalt roofing shingles are the most popular type of residential roofing material. Asphalt roof shingles are highly economical, starting at about .80 per square foot, and can be purchased in a wide range of sizes and colors.. Because they are easily cut and fastened, asphalt roof shingles are compatible with all kinds of roofing accessories and suitable to all kinds of roofing slopes. Asphalt roof shingles are also widely available, making them easily repaired. Roof 101 contractors provide all kinds of asphalt roof shingle related services, including installation, repair, cleaning, and maintenance, for well affordable prices.

Asphalt Roofing Shingles Materials and Qualities
Asphalt roofing is available in two types; glass fiber and organic shingles. Fiberglass asphalt roofing shingles contain a fiberglass reinforcing mat covered with adhesive asphalt and ceramic granules. Their best quality is fire-rating and installation simplicity. However, organic asphalt roof shingles are considered the best asphalt roof shingles, as they contain 40% more asphalt than fiberglass asphalt roof shingles, which make them heavier and therefore more durable and blow-off resistant. Organic asphalt roof shingles consist of a paper-based material saturated with ceramic granules and coated with asphalt. The ceramic granules provide UV ray reflection, while the asphalt coating provides waterproofing qualities.

The Life-Span of an Asphalt Shingle Roof
The life span of an asphalt shingle roof strongly depends upon the environment. Asphalt roofing in cooler climates lasts longer than those in warmer climates, so fiberglass asphalt roof shingles are used more in the South, while organic asphalt roof shingles are used in the North. Attic ventilation increases the life span, yet an asphalt shingle roof will generally survive 20-45 years.

The US Environment Protection Agency (EPA) has been trying to come up with roof materials and plans which help to save energy. Since it is the only part of the building which remains exposed to sun, it tends to absorb a lot of energy thereby increasing cooling costs.

Environmental Benefits Of Green Roofs

Apart from a marked decrease in cooling costs, green roofing technology has helped reduce heat loss and energy consumption during winter months also. They help bring down storm water run-off and filter pollutants especially carbon dioxide out of the air.

They also help increase the life span of the roof and also contribute to LEED points for the building. Leadership in Energy and Environmental Design (LEED) certification provides independent, third-party verification for your building project and determines if the building is indeed environmentally responsible, profitable and a healthy place to live and work at.

Green Roofs – Save Money and the Environment

Generally, it consists of a vegetative layer grown on rooftops. These roofs provide shade and help reduce heat and temperature of the surface and surrounding air. Depending on the load capabilities and the structure of your building, many include a variety of grasses, flowers or trees of different heights. In these systems, plants and soil replace the conventional roof coverings and the same layer of plants and soil protects the water proofing membrane.

Installing a green roof is a complex task and it is best to consult a landscape architect and an independent roofing contractor to analyze the effectiveness for your home or office.
