This system uses fastening plates to attach the membrane. This system providesa quicker installation without the use of adhesives and tapes. It is the most common method of TPO roofing installations.

Cooling Degree Days
TPO roofing membranes are popular in regions with more cooling degree days than heating degree days. As TPO membranes reflect UV radiation, the surface of the roof and the building remains cool during the summer months. This process reduces your cooling costs and decreases the number of carbon emissions.
 
Reflectivity and Sustainability
 
TPO membranes have a drastically lower environmental impact, making them the preferred choice of many companies and organizations. Most of these organizations have installed UltraPly™ TPO roofs on their office buildings, operating at less than 9kWh per square foot, and using nearly 90% less energy than other buildings.
The reflective roofing membrane of TPO roofs works in conjunction with skylights and solar panels, thereby allowing the companies reach their highest level of sustainability.

Benefits of TPO Roofing

Durability, Flexibility, and Versatility 

TPO roofing is not only highly resistant to tears, impacts, and punctures, but flexible enough to allow for building movement. TPO can be installed on low and high slope surfaces. It can be heated and reshaped multiple times, which is particularly helpful when completing roof details.
 
Economical and Easy to Install 
TPO can be quickly installed and requires little maintenance. TPO membranes are commonly fully adhered or mechanically attached to the underlying insulation or cover board. TPO Roofing membranes are available in different size rolls to reduce the number of seams and reduce labor cost.
Cool Roofing Matters
TPO roofs are light-colored roofs that can reflect the sun’s vitality. They play a critical part in decreasing the building’s cooling cost. TPO roofs benefit the environment as they reduce the urban heat island (UHI) effect.
 
Welded Seams for Long-Lasting Performance 
TPO membranes are heat-welded at 926ºC using a hot-air gun. The result is a combined seam that’s more grounded than the field of the film.
Sustainable and Environmentally Friendly 
TPO roofs are environmentally friendly as they don’t have any poisonous or dangerous fixing. They can be completely recycled

What to Look for in a Roof

There are many factors to consider when selecting a roof, including:

• How long will it last?
 
• How well it will hold up during natural disasters such as wildfires or hurricanes?
 
• Is it too heavy for the existing roof framing?
 
• Does the roof have enough slope?
Will the look complement the style of the house? 
• Is the type of roofing allowed by local building codes?
 
• And finally, how much does it cost?

DIFFERENT ROOF TYPES

1) Gable Roof

 
Also known as pitched or peaked roof, gable roofs are some of the most popular roofs in the US. They are easily recognized by their triangular shape.
 
If a gable roof is used in high wind areas, be sure proper braces are used and have the roof inspected after a large storm to ensure no damage occurred.
 
Suggested materials: Gabled roofs can be covered with almost any type of material including asphalt shingles, cedar shakes, metal, and clay or concrete tiles. However, if the roof also contains hips and valleys, it should either be shingled or roofed with metal shingles or standing seam to help prevent roof leaks.

2) Hip Roof

 
Hip roof has slopes on all four sides. The sides are all equal length and come together at the top to form a ridge.
They are excellent for both high wind and snowy areas. The slant of the roof allows snow to easily slide off with no standing water.
Hip roofs can offer extra living space with an addition of a dormer or a crow’s nest. Proper construction and maintenance is a must to prevent minor issues from turning into major problems.
Suggested materials: Hip roofs, like gable roofs, can be with almost any type of roofing material, such as shingles, metal, or tiles.
Types of Hip Roofs:
* Simple Hip: The most common type of a hip roof. It has a polygon on two sides and a triangle on two sides. The sides come together at the top to form a simple ridge.
* Cross Hipped: Similar to a cross gable roof. Use separate hip roofs on homes with different wings. The line where the two roofs meet is called a valley. Note: Valleys can allow water to pool. Proper waterproofing is a must.
* Half Hipped: A standard hip roof that has two sides shortened to create eaves.

3) Mansard Roof / French Roof

 
A mansard roof, also known as a French roof, is a four-sided roof with a double slope on each side that meet forming a low-pitched roof. The lower slope is much steeper than the upper. The sides can either be flat or curved, depending on the style.
Mansard roofs are great for people wanting flexibility to make future home additions. When first designing and building a home, you can actually save money by having a simple mansard design to start off. – You can then add on a garret or dormers at a later date. This will not only add value to the house, but it also allows homeowners to easily make additions as their needs change.
Mansard roofs cost more than typical roofs because of the embellishments and details that go into them. But, the added space and character can more than make up for the extra cost of initial construction.
Suggested materials: Since a mansard roof has such a unique design, choosing a unique material could make the roof that much more special. Using metal, such as copper or zinc for the steep portion of the roof, can be more expensive up front, but will require much less maintenance down the road, making it a good long-term choice.

4) Gambrel Roof

 
A gambrel, or barn roof, is much like mansard in a sense that it has two different slopes. The difference between the two is that the gambrel only has two sides, while the mansard has four.
Similar to mansard, the lower side of the gambrel roof has an almost vertical, steep slope, while the upper slope is much lower.
Gambrels are not only seen on top of barns, farm houses and log cabins. They are also seen on Dutch Colonial and Georgian style homes, as well.
The gambrel only uses two roof beams, along with gusset joints. Since the construction is quite simple with fewer materials needed, this helps to keep the cost of a roof down.
Gambrel roofs are also a great idea for outdoor sheds and storage buildings. Their shape can provide more storage without taking up more space.
Suggested Materials: The material used for a gambrel roof will depend on the style of the house. Wooden, asphalt or slate shingles are widely used. However, using metal will greatly cut down on the amount of maintenance required.

5) Flat Roof

 
As the name suggests, flat roofs appear to be completely flat with no pitch. However, they do have a slight pitch to allow for water run-off and drainage. These roofs are generally used on industrial or commercial buildings. However, they can also be installed on residential houses in both high and low rainfall areas.
Most people don’t consider the amount of available outdoor living space a flat roof can provide. So, don’t completely dismiss them when building a new home! The design is also conducive for installing PV solar panels for a more energy efficient and energy independent home.
Flat roofs are easier to construct than pitched roofs and require fewer building materials, keeping costs down. Although the upfront cost of building a flat roof is less expensive than a pitched roof, they can be more expensive in the long run due to maintenance and ongoing roof repair and replacement costs.
Suggested Materials: Ensuring a flat roof is waterproof is imperative. Using material that is continuous with no seams is the best. The most common materials used are tar and gravel, roll roofing, metal sheets, PVC, TPO, and rubber membrane.

6) Skillion Roof

 
Skillion is also referred to as a shed roof or lean-to. It is a single, sloping roof, usually attached to a taller wall. – It can be thought of as half of a pitched roof, or as a more angled flat roof.
Skillion roofs are mostly used for home additions, sheds and porches. However, they are also now being used on the entire structure of more modern style homes.
Suggested Materials: Because of the steep incline, rubber skins and roofing membranes can be eliminated. To give a more streamlined look, you can use standing seam rather than tiles or shingles. For a more Eco-friendly and energy independent home, large PV solar panels can also be installed.

7) Jerkinhead Roof

 
A Jerkinhead roof uses elements of both gable and hip roofs. It can either be thought of as a gable roof with hipped ends (cut short with the points turning downward). Or, it can be described as a hip roof with two short sides. – They may also be referred to as clipped gable or English hip roofs.
Suggested Materials: The Jerkinhead roof can be constructed of most any roofing material.

8) Butterfly Roof

 
A butterfly is a V-shaped roof constructed of two tandem pieces which are angled up on the outside. The midsection is angled downward where the two pieces meet into a valley. The overall effect is of a butterfly’s wings in flight.
The butterfly roof is popular for modern, Eco-friendly and tropical home designs. The valley in the midsection of the butterfly roof allows rainwater to be collected, making it beneficial for high drought areas. A downspout attached to a rain barrel or other type of water reservoir is usually installed for this purpose. The butterfly roof lends itself to an environmentally friendly home design, as PV solar panels, water collection systems and natural light can all be easily incorporated.
Ensuring the butterfly roof is waterproofed is essential. Drainage systems can get clogged, causing water to pool or leak. This will weaken the pillars over time, which can cause the roof to collapse.
The open design and tall windows can make it more difficult to regulate the temperature throughout the home. Some areas may be much warmer than others.
Suggested Materials: Using a solid, continuous membrane with no seams is the key to keeping a butterfly roof watertight. Other options are to use metal, organic materials or solar panels.

9) Bonnet Roof

 
Bonnet roofs, also known as kicked-eaves, are double sloped with the lower slope set at less of an angle than the upper slope. It’s like a reverse Mansard. The lower slope hangs over the side of the house. This overhang is an excellent cover for an open porch.
Bonnet roofs are not commonly used roofs in modern houses. They were mainly used in French Vernacular and can be seen in regions of Louisiana and Mississippi. Water easily runs off the slopes of the roof and the modified hip structure make it more durable than a gable roof.
Although water easily runs off the slopes, valleys are formed where the two slopes meet. This can cause snow and water to pool. Extra precaution is needed to waterproof these areas.
Suggested Materials: Bonnet roofs can be made from most any type of material, including shingles, metal and natural stone.

10) Saltbox Roofing

 
A salt box roof is asymmetrical in design, with one side being more of slightly sloping flat roof and the other more of a lean to, with gables at each end.
Saltbox houses are variations of early Colonial and Cape Cod designs. They arose from the need for more room. Early Americans realized they could add more space with less material by adding a lean to roof to an existing gable roof. Soon homes were built with the lean to roof already added.
Suggested Materials: Saltbox roofs can be made from most building materials.
