There is no question which type of shingles Tampa homeowners should choose! 3-Tab Shingles are a single layer, flat, and economical. Architectural (dimensional) Shingles are heavier, feature two or more layers laminated together, and offer a much better structural defense. They are engineered to look like natural slate or wood shakes, but more importantly, their multi-layered structure provides superior protection against hail, wind uplift, and impact damage. While they cost slightly more upfront, their longer warranties (often 30 years to lifetime) and better resistance make them the superior investment for structural protection.
