HVHZ Certified · All Permits Handled · Wind Mitigation Docs Included

Shingle roof replacement costs in South Florida vary based on roof size, pitch, existing layers to be removed, deck condition, product selection, and the specific city's permit fees. HVHZ-approved shingle products required in Miami-Dade County are generally more expensive than standard Florida-approved shingles because of the additional testing and certification they must carry. Premium and Class 4 impact-resistant options carry a further premium over standard architectural shingles.

AGK Construction & Roofing provides a detailed written proposal after a free on-site roof inspection — including all material costs, labor, permit fees, and the complete wind mitigation documentation package. We do not publish price ranges because they are genuinely too variable to be meaningful without knowing your specific roof. Call (954) 807-3455 or book a free inspection to get an accurate proposal for your property.

Florida Building Code allows a maximum of one overlay — meaning new shingles can be installed over an existing single layer of shingles, but only if the existing layer is in good condition and the deck is structurally sound. If there are already two layers of shingles on the roof, a complete tear-off is required before new shingles can be installed. Most roofing contractors and insurance carriers in South Florida prefer or require a complete tear-off regardless of existing layer count.

The practical issue with overlays in South Florida is that they prevent a proper inspection of the roof deck — and deck damage is extremely common on older South Florida homes. A complete tear-off allows us to inspect every square foot of the deck, replace any damaged or soft areas, upgrade the deck attachment to HVHZ requirements, and install the secondary water resistance layer properly. AGK recommends and performs complete tear-offs on all shingle replacements for these reasons.

In South Florida's climate — intense UV exposure, heat, humidity, heavy rain, and occasional hurricane-force winds — asphalt shingles typically last 15 to 25 years, depending on the product quality, installation quality, and maintenance. This is shorter than manufacturer warranties might suggest, which are based on more temperate climates. The intense UV radiation and heat cycles in South Florida accelerate shingle aging, particularly on west and south-facing roof slopes.

Higher-quality architectural and premium shingles, particularly those with algae-resistant granules, tend to perform better in South Florida's climate. Class 4 impact-resistant shingles are designed to resist wind-driven debris — a significant advantage in a hurricane-prone region. Proper installation with HVHZ-compliant products and regular maintenance (cleaning, minor repairs) maximizes the lifespan of any shingle system in South Florida.

Yes — HVHZ-approved asphalt shingles are a very good choice for Miami-Dade County single-family homes, particularly for homeowners who want the best combination of cost, performance, and insurance acceptability. Shingles are significantly less expensive than tile or metal roofing while still meeting the HVHZ wind resistance standards required in Miami-Dade. When installed correctly with proper deck attachment and secondary water resistance, HVHZ-approved shingles perform exceptionally well in South Florida's climate.

The key is using only HVHZ-approved products — not all shingles sold in Florida carry HVHZ approval. AGK specifies only HVHZ-approved products on all Miami-Dade County installations and provides the product approval documentation your building inspector and insurance carrier require. If you are considering shingles for a Miami-Dade property, call (954) 807-3455 for a free consultation on the best product options for your specific situation.

A wind mitigation inspection is an assessment of your home's ability to resist wind damage, conducted by a licensed inspector and submitted to your insurance carrier to calculate wind premium credits. The inspection evaluates several features of your roof system — roof age and shape, roof covering product, deck attachment method, secondary water resistance, and roof-to-wall connections. Each feature is rated and contributes to your overall wind mitigation credit.

A properly installed new shingle roof by AGK is specifically designed to maximize your wind mitigation credit. We install with 8d ring-shank nail deck attachment (the strongest rating), self-adhering secondary water resistance, and HVHZ-approved shingles — all of which contribute to the best possible wind mitigation ratings. We provide the complete product approval documentation your wind mitigation inspector needs, including the Florida Product Approval NOA with the installation method that was used, to ensure you receive full credit for every feature we install.

Yes — completely. AGK handles the entire permit process from start to finish. We prepare the permit application, submit it to the correct building department for your city, manage all plan review communications, schedule and pass the final inspection, and close the permit officially. You never deal with the building department at any stage.

A shingle roof replacement requires a building permit in every city and municipality across Miami-Dade and Broward County. Any contractor who offers to do the work "without pulling permits" to save money or time is putting you at serious risk — an unpermitted roof installation is a code violation, creates problems with your insurance coverage, and will surface in every future title search on your property. Every AGK shingle installation is fully permitted and inspected.
