Algae

Algae is a term that encompasses a large number of organisms that have chlorophyll but are distinguished from plants by an absence of roots, stems, and leaves.

Algae is a term that encompasses a large number of organisms that have chlorophyll but are distinguished from plants by an absence of roots, stems, and leaves. A common form of algae found on roofs is blue-green algae, a cyanobacteria. Despite the name, algae will appear as black streaks on a roof. It is most often seen in moisture-laden environments like coastal areas and humid climates. Algae doesn’t damage asphalt shingles but can alter the color and make them appear aged. Algae can sometimes be mistaken for moss, lichens, or mold.

Malarkey algae resistant (AR) shingles and those with Scotchgard™ Protector from 3M combat algae growth, keep roofs looking cleaner for longer, and come with multi-year warranties.

Architectural Shingles

Architectural Shingles

Also known as "laminate shingles." Typically made of two shingle layers sealed together with lamination adhesive.

Also known as "laminate shingles." Typically made of two shingle layers sealed together with lamination adhesive. For a traditional architectural shingle, the top layer is cut into a sawtooth pattern and laminated to an uncut second layer, known as the "backer" or "shim." This gives the shingle a more dimensional look than a traditional 3-tab shingle. Special color blends of granules are strategically applied to the shingle and a shadow line is added to create further dimension for a distinguished look.

Architectural shingles are fastened so nails penetrate both layers. Malarkey makes the nailing of architectural shingles quicker and easier by providing a true widened nailing area called The Zone®.

Pitch represents the incline of a roof expressed as a ratio based on the entire span of the building.

Pitch represents the incline of a roof expressed as a ratio based on the entire span of the building. Put another way, a roof’s pitch is its vertical rise divided by its horizontal span. For example: a roof that rises six feet over a 12 foot span would be expressed as “1 to 2”. Pitch can be expressed as a fraction, which in this case would be ½. Roof pitch is not typically used in most modern construction practices; roof slope is used to determine the appropriate roofing system.

Rain Seal

A rain seal helps hold shingles together during high winds and protects against wind-blown rain entering beneath the shingles.

A rain seal helps hold shingles together during high winds and protects against wind-blown rain entering beneath the shingles. Malarkey laminate shingles are manufactured with an extra line of defense in the critical area for laminated shingles, with double SEBS asphalt rain seals. Malarkey's SEBS asphalt has adhesive properties to join the shingle together and cohesive properties to prevent it from separating. SEBS is also flexible down to 0หšF (-18หšC), ensuring the rain seal remains intact through freeze and thaw cycles.

Seal-Down Strip

Seal-Down Strip

Shingles are manufactured with strips of a factory-applied, thermal sealant that is activated by the heat of the sun after the shingle is on the roof. 

Shingles are manufactured with strips of a factory-applied, thermal sealant that is activated by the heat of the sun after the shingle is on the roof. Exposure to the sun’s heat typically bonds each shingle securely to the one below, but cold weather installations may require the shingles to be sealed by hand. Sealants are important to help hold shingles in place during high winds, which in turn helps to protect your home against leaks.

Troughing

A shallow, trough-shaped depression that can occur on an architectural shingle just above the nailing lines. If wind-driven rain enters between the shingle layers, it can become trapped and move laterally along the trough, resulting in potential leaks. Malarkey architectural shingles feature The Zone®, with a 1¾" nailing area for more accurate fastener placement and a tapered shim to prevent troughing.

A shallow, trough-shaped depression that can occur on an architectural shingle just above the nailing lines. Troughing is caused when the bottom, laminated layer of an architectural shingle, known as the shim, abruptly ends and the top layer of the shingle dips down in the empty space created. The troughing effect is magnified when the shingle is high-nailed, penetrating only a single layer of the shingle and pulling it down. If wind-driven rain enters between the shingle layers, it can become trapped and move laterally along the trough, resulting in potential leaks. Malarkey architectural shingles feature The Zone®, with a 1¾" nailing area for more accurate fastener placement and a tapered shim to prevent troughing.

Nailing area over 3x larger than other laminate shingles for improved installation.

One of the most critical aspects of a successful roofing project is correct installation. Improper fastener placement is the leading cause of incorrect shingle installation, which can subsequently void the warranty as well as lead to leaks or blow-offs. Malarkey architectural shingles are manufactured with The Zone® – a patented 1¾" nailing area over 3x larger than other laminate shingles that dramatically improves correct fastener placement.

The Zone Tapered Shim
The Zone Tapered Shim

Malarkey combines a tapered shim design with The Zone®  nailing area to provide a substantially larger overlap area with a smoother transition, which prevents “troughing” of water. A standard flat shim design can cause troughing, allowing water to run sideways under the shingle and lead to leaks.
