What does the Asphalt Roofing Metrical cost impact the price of Shingles

Asphalt roofing comes with a variety of aspects. We'll be discussing a few of the elements that determine the degree to which the roofing shingle will adhere to the roof. We will also discuss crucial terms like melting viscosity and penetrating value. These parameters can affect the cost of shingles.

Penetration value

The values of penetration indicate the durability of asphalt roofing. These numbers show the resistance of asphalt to the forces of abrasion and other. The values are usually determined by the asphalt's hardness which can range between 40 and 80 percent. The value of penetration will increase when asphalt is more hard than 40-80 percent. However it will decrease when asphalt's hardness is less. The ratio of penetration and the softening point of every asphalt type is a major factor in determining the value of penetration.

Two methods are employed to measure asphalt's penetration rates. The first method involves heating the asphalt in a cup that is filled with brass. The second method uses a tiny flame to flash the sample. The flash point refers to the temperature at which an instantaneous flash takes place. This method is a great tool to calculate the maximum penetration value of an asphalt roofing. This technique is extremely well-liked by architects and engineers as it lets them determine the most suitable material for their particular project.


It is crucial to understand the melting viscosities of asphalt shingles prior to you decide. The ability of the material to stretch and harden is known as the melt-viscosity. A good range is 130-420 cps at 400 deg F/204 deg C. But the melting viscosity of the first melt could be any of the ranges between 425 and 500cps at 400deg F.

NIST (National Institute of Standards and Technology) has conducted research regarding the viscosity of asphalt. It is the characteristic that decides the way asphalt flows and adheres to reinforce the feels. According to the NIST roofing industry, roofers must use between 1 and 2 kg of asphalt for every square meters. The roofing substrate must be applied using the proper methods. In the case of roofing, the optimal viscosity of asphalt is 0.125 Pa.s. A 75cP (0.75 P.s.) is appropriate for spreader applications using mechanical equipment.

Rheology is a method to create an even more precise specification for asphalt-based materials. ASTM D36, D5 and D5 are utilized to assess the properties of asphalt. The viscometers measure the melting viscosity of asphalt between 25°C and 400°F. It is essential to comprehend the flow curve in order to determine the grade. To determine the processing conditions, Rheological data can also be helpful.

Weighing of the granules

Asphalt shingles are made mostly of asphalt, and are complemented by granules to shield against UV radiation. The granules are made of natural stone. They are later crushed and screened to create different grades. They are utilized in certain proportions in the blend mix in the process of manufacturing. The size and number of the granules determines the gradation of asphalt shingles.

The thickness of the roofing will increase as the asphalt roofing granules become heavier. Roof materials that are overlapped will have more weight per square foot. A granule could weigh 30-40 percent less than a brand new shingle. An older shingle than one that is brand new is lighter than one that is brand new.

Cost of shingles

You may be interested in the price of asphalt shingles for replacing your roof. It's dependent on the location you live in and how complicated your project is and whether professional help is needed. Asphalt shingles are the least expensive kind of shingles and they are also the lowest cost per square foot. Check out the prices of different kinds of asphalt shingles and find out the estimated cost.

Asphalt shingles are measured in kilograms. One pound equals one kilogram. There are a variety of colors for asphalt shingle, and they are offered in multiples of 10 kilograms. They're a good choice for shipping internationally since there is hardly any distinction between imperial and metric units. If you plan to deliver these units to Europe in metric units, but be aware that they might not be readily available in all countries.


Asphalt shingles that are metric in nature are extremely affordable and are a good choice for shipping internationally. Be aware, however, that not every country utilize the system of metric. It is possible to convert prices when shopping in Europe. We thank you for reading. We hope that you find this article useful.
