Dimensional or Laminate Shingles – 30 Year Warranty
The 30 year roof, also referred to as a “dimensional” or “laminate” shingle, has two layers of shingle material bonded together, which makes it thicker than the 3-tab shingle. This extra thickness provides added durability during hailstorms. Compared to the flat look of the 3-tab shingle, many homeowners prefer the look of the dimensional shingle Due to the upgraded look, most homeowners choose to upgrade to a laminate shingle when they replace their roof.
What are the different types of roof ventilation?
Passive Ventilation and Active Ventilation are the two types of attic ventilation.
Passive Ventilation depends on air flowing up through the soffit vents and out these exhaust vents.
Turbines, also known as whirlybirds, look like circular spinning vents. These vents work well, but the steel can rust over time and wear and tear causes them to stop spinning.
Ridge Vent requires a 2″ gap cut in the decking along the ridge and a 13″ plastic ridge vent is placed over the gap. This allows air to escape through the very top of the roof. Ridge cap shingles are installed on top of the ridge vent to cover up the plastic look.
Box Vents, also known as turtle vents or slant backs, look like little boxes on the roof.
Active Ventilation physically pulls the air out of the attic using a powered vent.
