Question 1

Are impact windows required in Miami-Dade?

Accepted Answer

Impact windows are required for new construction across much of Miami-Dade's HVHZ zone, and for substantial renovations affecting window openings. For existing homes, they're optional but recommended — they protect against hurricane-force wind and wind-driven debris.

Question 2

How much do impact windows cost in South Florida?

Accepted Answer

Impact window pricing depends on window count, size, frame material (aluminum vs vinyl), and any structural modifications needed. For a real price on your specific home, use the Roofweiler Price My Windows calculator at https://www.roofweiler.com/price-my-windows — add each window, pick your style, and see your price in minutes. No salesman, no in-home survey required to get a number.

Question 3

What protection do impact windows add beyond hurricane code compliance?

Accepted Answer

Impact windows use laminated glass that stays intact under wind-borne debris impact — protecting the building envelope, interior, and contents during a storm, and eliminating the need for separate shutters or panels since the glass itself is the protection system.

Question 4

How long does impact window installation take?

Accepted Answer

Whole-home impact window installations typically take 3-7 working days depending on window count and any structural modifications. Permits and inspections route through your county or municipality, which Roofweiler handles as part of every install.

Question 5

Aluminum vs vinyl impact windows — which is better for South Florida?

Accepted Answer

Aluminum frames are more traditional in South Florida, more durable under sun exposure, and standard for HVHZ commercial. Vinyl can offer better thermal insulation and lower upfront cost but is less common for HVHZ residential. We discuss the right choice based on your home, exposure, and budget during the site survey.

Question 6

Do impact windows lower my homeowners insurance in Florida?

Accepted Answer

Many South Florida insurance carriers offer a wind-mitigation premium credit for homes with documented impact-rated windows, since the laminated glass and reinforced frame reduce wind and debris damage risk. The specific discount amount varies by carrier and policy — confirm the credit with your agent or broker; Roofweiler provides the product documentation (NOA/Florida Product Approval) carriers require to apply it.

Question 7

What's the difference between impact windows and hurricane shutters?

Accepted Answer

Impact windows use laminated glass and a reinforced frame built into the window itself, so the protection is permanent and requires no action before a storm. Hurricane shutters are a separate system — panels, accordions, or roll-downs — that must be deployed before landfall and stored the rest of the year. Impact windows also stay in place year-round for security and noise reduction, not just storm protection.

Question 8

Do impact windows need a permit in Miami-Dade County?

Accepted Answer

Yes. Impact window replacement in Miami-Dade County requires a building permit, and the specific product installed must carry a current Miami-Dade Notice of Acceptance (NOA) for the wind zone. Roofweiler pulls the permit, files the required documentation, and schedules inspection as part of every installation.

Question 9

How long do impact windows last in South Florida?

Accepted Answer

Impact windows typically last 20-30+ years in South Florida when properly installed and maintained, though exact lifespan depends on frame material (aluminum generally outlasts vinyl in direct sun exposure) and salt-air exposure in coastal areas. The laminated glass itself doesn't degrade the way shutters can; most manufacturers back the glass and frame with a transferable warranty.
