Yes, built up roofs are a great option for any building. They are an economical, long-lasting roofing solution that is suitable for both commercial and residential properties. Built-up roofs offer a few different advantages over other roofing styles such as asphalt shingles.
They offer superior waterproofing and are very durable as they are made up of several layers of felt and asphalt, making them resistant to extreme weather conditions. They are also fire-resistant, saving you money on insurance premiums.
Additionally, they offer great noise reduction properties, meaning excessive noise pollution from the outside can be minimised. Whilst they are generally more expensive than other types of roofing materials, the fact that they can last up to fifty years makes them a great long-term investment.
How long will a built up roof last?
The average built up roof can last anywhere between 10 and 20 years when it is properly installed and maintained. However, there are a variety of factors that can impact the longevity of a built-up roof.
Factors such as the type of material used, how frequently the roof is inspected and maintained, and the local climate can all play a role in how long a built-up roof will last. Additionally, it is important to note that quality materials and good protection from the elements are essential in ensuring the longevity of a built-up roof.
To maximize the lifespan of a built-up roof, regular maintenance should include checking and replacing any worn-out materials, identifying and repairing any damage, inspecting the flashing and sealant around penetrations such as vents, and removing any debris or buildup from the roof’s surface.
With proper care and maintenance, a built-up roof can help protect your home for years to come.
What are common problems with built up roofing?
Built up roofing (BUR) is one of the most popular types of roof coverings due to its life expectancy and economical price. However, like all other roofing materials, BUR is susceptible to a variety of problems; the most common being:
1. Poor Installation: Installation mistakes or inadequate maintenance can cause materials to deteriorate, leading to reduced life expectancy and premature failure. Common installation mistakes include improper layering of materials, insufficient weather protection with flashing, and inadequate fastening.
2. Ponding Water: The accumulation of standing water due to poor drainage or inadequate slopes can lead to premature aging and damage. Water should not be left standing on any type of roofing material for long periods of time.
3. UV Rays: Prolonged exposure to UV rays can cause BUR and its components to break down rapidly, resulting in curling, deterioration, and cracking. Applying reflective material such as white paint, white roofs (cool roofs), or special membranes can help to reflect the sun’s rays, reducing deterioration.
4. Thermal Shock: BUR materials can shrink and expand when exposed to extreme temperatures, leading to cracking and possible failure. To prevent this, insulation boards should be placed beneath the BUR membrane and heat tape should be applied to seams, if necessary.
5. Animal Damage: Rodents, birds, and other possible pests can cause damage to BUR and tear into other roof components like flashing, ventilation, and insulation. It is important to inspect all roof components and seal any holes, repairs, or gaps in the roof to prevent animal intrusion.
Is a built up roof a flat roof?
A built-up roof (BUR) is not technically a flat roof, but rather a slightly sloped roof that is constructed by laying multiple layers of tar-saturated fabric known as felt over a plywood or metal base.
The layers are then covered with hot tar and gravel, which provides a heavy and durable protection against water and the elements. The pitch of the roof is typically between 1/8 and 1/4 of an inch per foot, which is not considered a flat roof by industry standards.
A flat roof typically has a pitch of less than 1/4 of an inch or 0%, however, the installation of a BUR can result in a pitch of up to 1/4 of an inch, which is still considered a low-sloped roof.
What is the difference between built up roofing and single ply roofing?
Built up roofing (BUR) is one of the oldest roofing systems, and has been around for decades. It consists of alternating layers of plastic membranes and bitumen-soaked felts with a surface of smooth gravel, tar, or asphalt.
The materials are adhered together with a heated mop and hot tar, making the roof more durable and resistant to the elements. The life expectancy of a built up roof (BUR) can range from 10-30+ years depending on how well it is maintained.
Single ply roofing is a type of flat roofing membrane system made of a single layer of manufactured material, typically plastic or a type of rubber. It is usually lightweight and available in a few different colors to match the building’s exterior.
Single ply membranes are much simpler to install than BUR systems, as they do not require additional layers of asphalt. The seams are reinforced with a special tape or sealant, making them more waterproof and protecting against weathering.
Single ply roofing has a life expectancy of 15-20 years, with proper maintenance.
Is TPO built up roof?
No, TPO (thermoplastic polyolefin) is a type of single-ply flat roofing membrane, rather than a type of built up roof. TPO membranes are made from reinforced ethylene propylene rubber and chlorine-based compounds to create an extremely durable, tear-resistant material.
Depending on the environment and application, TPO has some of the best heat reflectivity and ultra-violet resistance available in a flat roof system. It also contains flame-retardant additives that allow it to meet the safety requirements of most building codes.
TPO is relatively new to the commercial roofing world, but it is becoming increasingly popular for its cost-effectiveness and long-term durability.
How many layers will a typical built up roof covering have?
A typical built up roof (BUR) covering will typically consist of three or four layers. The first layer is the felt underlayment, which is a layer of roofing felt that is placed directly over the roof deck prior to installing the roofing membrane.
The second layer is an asphalt-based adhesive, which is applied directly over the felt underlayment and creates a waterproof seal over the entire roof area. The third layer is the aggregate surfacing, which is typically composed of gravel or crushed stone that is spread over the asphalt-based adhesive to seal and protect the roofing membrane.
The fourth and final layer of a typical built up roof covering is the top coat, which is applied over the aggregate surfacing and provides additional protection for the roof. In some cases, a fifth layer may be included in the roof covering, which includes a reflective membrane or a modified bitumen material.
What does it mean when a roof is built up?
When a roof is built up, it refers to a type of roof construction in which multiple layers of substrate are applied to a flat or gently sloping roof. This type of roof construction is generally used to increase the weather resistance of a roof and to create a more aesthetically pleasing look.
Typically, a roof built up will have multiple layers of waterproof membranes, such as felt, applied to its surface. This is then followed by one or more layers of surface material, such as roofing shingles, or metal roofing panels.
The roofing material will then be secured to the roof using fasteners or adhesives. This type of roof construction is popular because it can be customized to provide the desired look for a building and it is relatively easy to install and maintain.
What is the roof to have on a house?
When selecting a roof for a house, there are many factors to keep in mind. The type of roofing material should be chosen based on the climate, local building codes, and personal preference. Common roofing materials include asphalt composites, wood or cedar shakes, slate, terra-cotta tiles, concrete, and metal.
Each material has its own advantages and disadvantages, and some materials may be more appropriate for certain climates or environments than others. It’s also important to consider the size, shape, and pitch of the roof based on the size, shape, and style of the house to ensure it is built to last.
Additionally, energy efficiency should be a factor when selecting materials, as some materials may have better insulation properties than others. Finally, the cost should be taken into consideration, as some materials and designs may be more expensive than others.
What type of roofing lasts the longest?
The type of roofing that lasts the longest is metal roofing. Metal roofs typically last up to 50 years or more, depending on the quality of materials and the climate in which your home is located. Metal roofs are more resistant than asphalt shingles to adverse weather and have a much longer lifespan.
Metal roofing is available in a variety of styles and colors, and due to its lightweight nature, it is easy to install compared to heavier roofing materials. Overall, metal roofing outlasts most other roofing materials and is an excellent choice for homes in regions with extreme weather conditions, such as high winds, hail, and extreme heat or cold.
Additionally, metal roofs are fire-resistant and reduce energy costs during the hot summer months, making it a practical and economical option for long-term roof protection.
What is the most durable type of roof?
Clay tile roofs are the most durable type of roofing material available. This is because clay tiles are extremely strong and long-lasting, with the potential to last for more than a century. Clay roofs require very little maintenance and are strong enough to withstand extreme weather, including hail, high winds, and even wildfires.
Additionally, clay tile roofs are highly heat resistant, and studies have shown that they can reduce cooling costs up to 30% compared to other types of roofing. Clay tile roofs also come in a variety of attractive colors and shapes, making them a popular choice for many homes.
Ultimately, if you’re looking for the most durable type of roofing material, clay tile is the way to go.
What are the 4 most popular types of residential roofing?
The four most popular types of residential roofing materials are asphalt shingles, metal roofs, tile roofs, and slate roofs.
Asphalt shingles are the most popular type of residential roofing material due to their durability, affordability, and relatively low maintenance. They are available in a variety of colors and textures, and come with weatherproofing options to stand up to rain, snow, and other inclement weather.
Metal roofs are becoming increasingly popular. They are lightweight and highly durable, as well as energy efficient and fire resistant. They are available in numerous colors, textures, and styles to fit a variety of homes.
Tile roofs offer aesthetic longevity and a classic look. They come in a variety of shapes, sizes, and colors and last longer than other materials. They are resistant to inclement weather and can be recycled, making them a great environmental choice.
