A roof is usually the first line of defense on any building; It protects the building&#;s occupants and their treasures from nature&#;s elements such as rain, strong winds, heat as well as cold. Over time, roofs have evolved from just covers over people&#;s heads to aesthetic elements in a building&#;s design.

Today, our focus will be on laminated asphalt roofing shingles.


Asphalt Roofing shingles

Before asphalt shingles were invented, the most common type of roofing shingles was wooden shingles. This is because wooden shingles were readily available (since their base product is wood), they were light in weight and could also take varying roof angles. The main disadvantage of wooden shingles besides the quick deterioration following exposure to changing weather patterns was that they were quick to catch and spread the fire. These shortcomings, among others, led to the innovation of fireproof and water-resistant asphalt shingles.


The first asphalt shingle produced was a single ply roofing shingle with 3 tabs per ply meaning that each tab was separated by a slit from the next tab. With all their advantages, the asphalt shingles did not perform well for low-pitched roofs, as stagnating water on the roof could easily find its way into the roof structure. These asphalt shingles however performed well on high pitched roofs from 25 degrees and above. The roof pitch refers to the steepness of a roof and is always expressed in degrees.


Laminated Asphalt Shingles

As roof designs and complexities continued to evolve, technologies in the manufacturing of asphalt roofing shingles continued to evolve. Homeowners and developers needed a product that could fit their specific style; a true expression of their individuality.


This is how the double-layer asphalt shingles also known as laminated shingles was born. The term architectural simply refers to their high-level aesthetic features while laminated emphasis the concept of binding two layers of the traditional asphalt shingles together.

Features of Laminated Asphalt Shingles


Blow Off Protection

The Laminated Asphalt Shingles come with printed nail lines that guide installers to position and fasten the shingles correctly. This helps to help keep them on the roof and prevent them from blowing off in high wind.


Built-In Algae Resistance

The Laminated Asphalt Shingles have special algae-resistant granules to help inhibit the growth of blue-green algae that can cause unattractive black stains, streaks, and discoloration of the shingles.


Exceptional Bonding

For most roofs, when the wind lifts them up, water can sneak in underneath and cause a leaky roof. Laminated Asphalt Shingles have sealant strips that are activated by the sun&#;s heat to create a strong bond and ensure maximum protection against wind uplift, blow-off and water penetration.


Fiberglass Mat

Cambridge double-layer asphalt shingles have a fiberglass mat that is coated top and bottom with weathering asphalt, then surfaced with colored granules. It&#;s heavy-duty for exceptional durability and structural integrity.


Benefits of Laminated Roof Shingles

&#; Highest wind ratings compared to other asphalt shingles- Cambridge shingles have the highest wind resistance above 130MPH, not only because they are heavier in weight but also because they are specifically engineered to withstand more stringent weather changes.

&#; Impact resistance and fire resistance.

&#; Built-in Algae resistant granules hence no ugly stains and discoloration on your roof.

&#; Available in the full range of colors to blend in with your exterior walls.

&#; Efficient to install due to the smart nailing zone provision with an additional wind blow-off protection.

Cambridge Double Layer Asphalt Shingles: All You Need ...

A roof is usually the first line of defense on any building; It protects the building&#;s occupants and their treasures from nature&#;s elements such as rain, strong winds, heat as well as cold. Over time, roofs have evolved from just covers over people&#;s heads to aesthetic elements in a building&#;s design.

Evolution of Roofs

In the past, clay and metal were the predominant roofing materials of choice. They had their limitations and were difficult to use on low pitched and curved roofs primarily because their nailing application method had little to no overlap, thus, they would always cause leakages. They also could not take complex shapes without breaking.

As the roofing industry continued experimenting with different varieties of roof shapes designs, better products such as asphalt roofing shingles, stone coated metal tiles, and App waterproofing membranes were introduced to keep up with the complex roof details that continued to emerge.

Today, our focus will be on the Cambridge double layer asphalt roofing shingles.

Roofing Shingles

For more information, please visit shingles vs tile.

The word shingle is in fact derived from the German word Schindle which was used to refer to any tile that is placed on a building as a roof covering. Shingles therefore can refer to either wooden, metal or asphalt/bituminous roofing materials. It is for this reason that your developer and architect should carefully specify the type of shingle they require when working on your project.

Cambridge Double Layer Vs Traditional Shingles

  • Cambridge double layer shingles are double layered hence heavier with longer lifespan on up to 50 years. Most traditional shingles last up to 25 years.
  • Cambridge double layer shingles are more popular than the traditional single tab shingles. This is because they can take significantly low lower roof pitches from 9.5 degrees. They also resemble a very popular natural slate and wooden shingles look without the burden of algae, flammability and constant maintenance expenses.
  • Cambridge double layer shingles have less wastage and are more efficient to install because there are no slits in between the tabs
  • They are available in many beautiful colours
  • Although the Cambridge shingles are 15-20% more expensive than the traditional asphalt shingles their product guarantee ranges between 25-30 years while that of the traditional 3 tab shingles is between 10-15 years.

Cambridge Double Layer Shingles Vs Stone Coated Tiles

Stone coated tiles are zinc-aluminium base tiles coated with ceramic granules, they are the most current innovation in metal roofing systems and some have been done to resemble the asphalt shingles, hence one will hear about stone coated &#;Shingle profile. Cambridge shingles have the following advantages over stone coated tiles:

  • Cambridge shingles can take any shape. Cambridge asphalt shingles are easy to install with limited wastages because unlike stone -coated tiles that are not flexible enough to bend without breaking.
  • They are not prone to leakages unlike stone coated aluminium tiles that expand and contract over time due to thermal expansion
  • Less structural support during construction of the roof structure, since they are fixed on a firm decking while the stone-coated tiles are laid directly on closely spaced battens.
  • They don&#;t need additional accessories such as valleys, angle ridges because shingles ridges are made from shingle off cuts due to their flexibility.
