The shingle you choose decides how your roof looks from the curb and how it stands up to Utah weather : wind, hail, snow load and summer heat. Dedication Roofing is a Malarkey certified contractor, and this page is about the product rather than the job: what separates the architectural lines from the impact-resistant ones, what the ratings printed on the wrapper actually mean, and which warranty figure your installation buys you.

Choosing a shingle is one half of the decision; the other half is the installation it goes onto. If your current roof is due for renewal, see roof replacement, which covers full tear-off, overlay and new construction.
UL 2218 impact. Impact resistance is graded Class 1 to Class 4, Class 4 being the highest. A shingle earns Class 4 when a two inch steel ball dropped from twenty feet leaves no crack on the back of it. The Vista and Legacy lines both carry Class 4.
ASTM D3161 and ASTM D7158 wind. These two standards measure different things. D3161 is a fan-induced test. D7158 calculates the uplift force wind actually exerts and accounts for building height and exposure, which makes it the more meaningful of the two. Legacy Scotchgard is rated Class F under D3161 and Class H under D7158, and Class H is the highest classification D7158 awards.
The warranty is a separate number from the test. Malarkey limited wind warranty cover is 110 mph as standard and rises to 130 mph only when the shingles go on alongside other Malarkey components: starter, ridge and underlayment from the same system. Mixing brands across the assembly is the usual reason a roof ends up on the lower figure without the owner knowing.
Algae cover is line specific. Legacy Scotchgard includes 3M Scotchgard Protector and carries a limited lifetime warranty against blue-green algae, the organism behind black streaking. Vista carries no algae warranty at all. If streaking is a concern on your roof, that one difference decides which line to specify.

What clients say
Architectural shingles are built from multiple laminated layers, giving a dimensional profile with real depth and shadow; three-tab shingles are a single flat layer with a uniform pattern. The laminated construction is heavier and carries higher wind and impact ratings, which is why architectural shingles have become the standard on replacement roofs. Three-tab is now mostly seen on older roofs coming off.
Impact-resistant shingles are graded under UL 2218, where Class 4 is the highest rating — awarded when a two-inch steel ball dropped from twenty feet leaves no crack on the back of the shingle. Malarkey’s Vista and Legacy lines both carry Class 4. Along the Wasatch Front, where hail and wind-driven debris cause most sudden shingle damage, the upgrade is worth pricing out rather than dismissing. Malarkey notes Class 4 roofs often qualify for an insurance discount; your agent can confirm whether yours does.
Asphalt shingles in Utah last longer on some slopes than others, which is why a roof rarely fails evenly. South- and west-facing slopes take the most UV and age fastest; north slopes hold moisture and grow algae. Attic ventilation matters as much as the shingle itself, because trapped heat cooks a roof from underneath. Rather than quote a number, we look at granule loss, sealant condition and how the slopes are ageing relative to each other.
Within the shingle itself the variable is the line. Moving from a standard architectural shingle up to an impact-resistant one changes the material cost but not the labour, and the algae-resistant Legacy Scotchgard sits differently again. What the whole roof costs is a separate question, set by square footage, pitch, how many layers are coming off and the condition of the decking underneath, and that is covered on the roof replacement page. Dedication Roofing quotes on site, in writing, at no cost.
Only some shingle lines resist algae and black streaking, and the difference matters. Malarkey’s Legacy Scotchgard shingles include 3M Scotchgard Protector and carry a limited lifetime warranty against blue-green algae — specifically Gloeocapsa magma, the organism responsible for black streaking. Other biological growth is excluded. Malarkey’s Vista line carries no algae warranty. If streaking is a concern on your roof, that distinction decides which line to specify.
Malarkey’s Legacy Scotchgard shingles are rated ASTM D3161 Class F and ASTM D7158 Class H. The two standards measure different things: D3161 is a fan-induced test, while D7158 calculates the actual uplift force wind exerts and accounts for building height and exposure, which makes it the more meaningful of the two. Class H is the highest classification under D7158.
A test rating and a warranty are different things. Malarkey’s limited wind warranty is 110 mph as standard, and rises to 130 mph when the shingles are installed alongside other Malarkey components — starter, ridge and underlayment from the same system. Mixing brands across the assembly is the most common reason a homeowner ends up with the lower figure without realising it. Ask any contractor which number your quote actually buys.
Yes — shingle installation affects the warranty, and more than most people expect. Malarkey’s instructions require approved corrosion-resistant nails and do not permit staples. Slopes between 2:12 and 4:12 require a double layer of underlayment, and slopes above 21:12 require six nails per shingle plus hand-sealing underneath. Miss any of those and the manufacturer can decline a claim — which is what certified installation is actually protecting.
