Why Malarkey's Legacy is the Best Roofing Shingle?
The Malarkey Legacy roofing product is, by far, the best high-performance asphalt shingles. They are extremely smooth to install and last for 25 to 35 years. (average shingles last for 15 to 20 years) The Legacy shingles have two significant advantages: superb-quality and subtle but revolutionary designs.
The amount of asphalt used gives an asphalt shingle its thickness, weight, and adds to its strength. Up to a point, heavier shingles outlast lighter ones. However, the most critical factor is the quality of the asphalt. High-quality asphalt is almost always flexible and less brittle.
In addition, finely pulverized minerals, called "filler", are added to the asphalt to give shingles toughness and body. These tiny minerals increase the lifespan of the shingle. Not enough filler causes shingles to become soft and they scuff easily. The right amount of fillers makes shingles flexible, which is the desired outcome.
Next, granules are adhered to asphalt, adding colour and a layer of protection from UV rays. High-quality roofing shingles often exhibit strong granule adhesion.
Over the years, Malarkey has continually developed its roofing shingle technology and came up with the NEX Polymer Modified Asphalt. They utilize polymers from repurposed/recycled materials to enhance shingle performance. In particular, this technology improves shingle flexibility, granule adhesion, cold weather installation, and impact resistance. (Legacy has a Class 4 impact resistance rating)
Revolutionary Designs to Prevent Shingle Blow-off
A 2,500 square feet roof requires over 6,000 roofing nails. The correct placement of the fasteners is time-consuming since most roofing shingles have a narrow nailing zone - 3/8" to 1/2". High or low nails result in shingle blow-offs, which is common in Edmonton.
Malarkey created The Zone to eliminate the inherent conflict between fast installation and accurate fastener placement. The roofing shingles are equipped with The Zone have a 1-3/4" nailing area, about up to three times larger than an average shingle.
An additional advantage of The Zone is that they provide a significant reduction in blow-back leaks. Blow-back leaks happen when a shingle's rain seal (the glue line at the top of the backing strip) is breached. When this happens, water-blown can leak behind a shingle.
What is Class 4 Impact Resistance Rating?
Before 1996, there was no defining standard existed to distinguish how well a roofing material can withstanding impact. In 1996, property insurance industry experts teamed with the Institute of Business and Home Safety (IBHS) and the Underwriter’s Laboratory (UL) to develop the UL 2218 classification.
UL 2218 set a national standard for roof impact resistance by rating materials from Class 1 through Class 4.
Class 4 rating is the highest and the toughest. During a Class 4 impact resistance test on asphalt shingles, a 2” diameter steel ball is dropped from 20 feet onto the shingle to simulate the impact of hailstones. This is done twice in the same spot. This process is then repeated in six different places. A shingle passes the test if it does not show any visible evidence of tearing, fracturing, cracking and splitting.
Are Class 4 asphalt shingles hail proof?
The short answer is “no.” No asphalt roofing material is entirely hail proof; however, homeowners in hail prone areas can reduce their risk of impact damage by installing Class 4 shingles.
