Roof replacement in Ojus, FL
The median home in Ojus was built in 1970, a figure that suggests many roofs here are now well past their original service life. The county median is 1980, so Ojus housing is older than the county as a whole. Most of the 78.4 percent of homes built before 1980 are likely to have an original or second roof that needs attention. Your permit starts with Miami-Dade County, not the town.

Roof age here
How old are Ojus roofs and what it means for you
About 78.4 percent of Ojus housing units were built before 1980, against 49.6 percent across Miami-Dade County. Ojus has far more older stock than the county overall. That suggests a large share of roofs here are reaching the age when a full replacement becomes the practical choice.
Florida insurers look at roof age closely. An insurer may not refuse a policy because a roof is under 15 years old alone. For a roof 15 years or older, the insurer must let you have an authorized inspector check it at your cost, and may not refuse or non-renew coverage solely for age if the inspector finds 5 or more years of useful life left. Take the details to your insurer or agent for your own policy.
Permit and inspections
Who issues your roof permit in Ojus
Ojus is an unincorporated census-designated place, so the county building office issues your roof permit. Miami-Dade County Regulatory and Economic Resources handles Building and Permits. Ask the county to confirm the current steps before you start, since the permit office is the authority here.
Miami-Dade is inside the High Velocity Hurricane Zone, which applies stronger roofing rules than most of Florida. Every re-roof needs a permit there, and the application must be completed by a licensed contractor. Your roofer should tie deck nailing and the secondary water barrier to the permit inspections.
- Confirm the permit before tear-off begins.
- Ask how many inspections the county requires for your roof.
- Confirm that the roof deck is nailed to the code the county inspector checks.
Florida re-roof rule
The 25% rule and when a full re-roof applies
Florida's 25 percent rule limits repairs. Under the Ojus housing mix, many older roofs fall into this range, so a partial patch can trigger a full replacement requirement. Confirm the threshold for your own roof before you schedule any repair.

Do I need a full roof replacement if only part is damaged?
Florida's 25 percent rule says that no more than 25 percent of the roof area may be repaired or replaced in any 12-month period unless the entire roof covering is replaced. Partial repairs above that limit can require a full replacement. A roofer can measure the damaged area against the roof size. Confirm the result with the Miami-Dade building office before you decide.
