Asphalt Shingles For Your Commercial Property
Considered as the most common roofing material, asphalt shingles are an inexpensive and easy to install roofing option for some type of commercial properties and residential roofing. In fact, it accounts for over 75% of all roofing materials that are installed today. For the past decade, this material has significantly evolved. Aside from its initial purpose of protecting the roof, many models now come with new features that make them environment-friendly: better energy performance, reduced roof temperature, and use of recycled materials.
If you are thinking of getting asphalt shingles installed in your business building or structure, perhaps it would be a good idea to know more about this material first. This way, you will be able to come up with a more informed decision.
Asphalt shingles are divided into two categories. Fiberglass shingles incorporate a fiberglass mat while organic shingles have a fiber mat made with wood products. More opt for fiberglass shingles because they are thinner and more light weight than its organic counterpart, making them easier to carry and more fire-resistant. Organic shingles, on the other hand, are better for cold weather.
- Organic shingles
These are the oldest asphalt roofing tile. Its cellular fiber substrate is made mostly with recycled paper and asphalt compressed under high pressure. It is more flexible, easier installed and more tear resistant than fiberglass shingles. They are also heavier, making them more resistant to strong winds, and are better at dealing with temperature changes.
- Fiberglass shingles
Currently, these are more popular than organic shingles. Composed entirely of glass fibers, these shingles are much lighter than its organic counterpart. And because less asphalt is used in its creation, it is also less expensive. They are also more resistant to heat, although it will require an underlayment of asphalt-saturated felt on the roof structure before it is installed.

Parts and Features
- Granular surface layer. This make up the outer layer of asphalt shingles, giving it its color and UV protection. This coating is made from basaltic deposits which are hard, durable, and opaque so it is protected from deterioration from the heat of the sun. There are those that are made to reflect heat to cool roof temperatures and prevent mold formation.
- Asphalt coating. This is the agent applied to waterproof and protect the roof. Its thickness is dependent on the shingle’s weight. Architectural shingles are made up of two layers of asphalt with a fiberglass mat in between.
- Base (or mat). The material of this element will tell the type and structure of a shingle. Organic shingle base are made of organic felt with asphalt while those of fiberglass shingles have a glass mat. It acts as the frame so it should be stable and resistant in all temperatures
- Adhesive tabs. Shingles have heat-activated adhesive tabs. Driving a nail through the adhesive tabs is a big no-no as this will prevent the shingles from locking into the roof deck.
- Nailing strip. The shingles need to be nail, not stapled as this will make them more prone to cracks. The nail heads has to visible on the surface and should not be driven too deep.
- Wind resistance. With the combination of nails and adhesive, asphalt shingles are resistant to wind. Most of them are able to resist winds over 100 km per hour. High-performance shingles are able to withstand winds of up to 220 km per hour.
- Solar reflectance index (SRI). This is the measure of the ability of the roof to reject solar heat. Newer shingles are now more solar-reflective so the roof is cooler during summer. The granular layer is the one that will reflect the rays of the sun without affecting the color of the roof.
You can find so many models of shingle in the market today in a variety of colors. Each one of them has their own features and manufacturers continue to improve them so they are more resistant to big weather disruptions.

- Shingles for peaks and ridges. Designed for the crest and ridges of the roof, these singles are available in one, two, and three thicknesses. It is available in up to 7 colors.
- Starting shingles. These are shingles that are half the size of a typical shingle and is created to start installation.
To keep the commercial roof in top condition, inspect the roof regulary or have a roofing maintenance plan in place. Do not do this more often as walking on certain parts of the roof can cause damage. For commercial properties that use shingles, inspect the attic areas to make sure that there is no humidity as this is a sign of inadequate attic ventilation. Check that the plastic cement below the flashings is in good condition and use a caulking gun for waterproofing.
Asphalt shingles that do not come with colorization are the ones that cost the least. With quality, higher quality colors and stylistic improvements, the prices rise in step. For the most part, it is the material’s quality that generally coincides with weight or thickness. Thick and heavy shingles mostly have a longer lifespan.
