Asphalt Shingle Installation in Duval County, FL

Yes — Duval County residential construction requires shingles rated for 130 mph design wind speeds under the Florida Building Code. All South Roofing installs shingles that meet this standard for homes throughout Jacksonville and the surrounding county.

Florida Building Code allows one new shingle layer over an existing layer only if the deck is in sound condition. If your Duval County home already has two layers, a full tear-off is required before new shingles can go down.

The black streaks are caused by algae growth that thrives in Jacksonville's high humidity and frequent rainfall. Choosing shingles with algae-resistant technology helps slow that growth and keeps your roof looking clean longer.

We inspect the deck, install a code-compliant underlayment, then lay shingles with the correct fastening pattern for Florida's wind zone. Flashing is set at every transition and penetration point to stop water from getting in.

If more than 25 percent of your roof area needs repair or replacement within a 12-month period, Florida Building Code may require the full roof to be brought up to current standards. All South Roofing can assess your specific situation during a roof inspection.

Yes — installation method matters to Florida insurers, and shingles installed to code with proper fastening patterns support your coverage. Work that does not meet Florida Building Code requirements can create problems when you file a claim.
