Commercial roofing in Ojus, FL
In Ojus, 59.5 percent of homes sit in buildings with 10 or more units, so most property managers here deal with flat or low-slope roofs on multi-unit structures. Those roofs drain slowly, carry more weight and need a permit from the county, not the town. Check the permit path, the slope and the drainage plan before you sign a commercial roofing contract.

Why multi-unit buildings change the roofing job in Ojus
Ojus has 8,389 housing units, give or take 525, and most of them are in larger buildings. Miami-Dade County as a whole shows 40.2 percent in buildings of 10 or more units, so Ojus is well above the county average. A roof over a 20-unit building is a different job from a single-family roof, and the bid should say so.
The median home here was built in 1970, and 78.4 percent of units predate 1980. By our arithmetic, that is roughly 28 percentage points above the county share of 49.6 percent. Many of these roofs are likely past their first covering, so a tear-off to the deck may come up on older buildings even when the leak looks small.
Permits and code
Permits, the county office and the HVHZ rules
Ojus is an unincorporated census-designated place, so the Miami-Dade County Regulatory and Economic Resources office issues roof permits here, not a town building department. Confirm the permit path with that office before work starts.
Miami-Dade is one of two counties in the High-Velocity Hurricane Zone. Under the HVHZ rules, all roofing work needs a permit, including repair and maintenance, and the application must be completed by a licensed contractor. Inspectors also check the roof before the system is covered.
Drainage and bids
Checking low-slope drainage in Miami-Dade bids
In the HVHZ, a new low-slope roof needs at least a quarter inch of slope per foot, and no loose-laid ballasted system is allowed. Ask each bidder to show how the roof will drain within 48 hours of rain, and whether the design includes emergency overflow drains or scuppers where a parapet could trap water.
- Confirm the bid lists the Miami-Dade product approval for each material.
- Ask whether the bid includes a tear-off to deck or only a recover, and why.
- Ask how ponding water will be handled and whether a structural review is needed.
- Check that the roofing contractor holds the state roofing certification required by statute.

Why do multi-unit buildings in Ojus need a different roofing bid?
Of the 8,389 housing units in Ojus, 59.5 percent are in buildings with 10 or more units. The county share is 40.2 percent. A larger roof means more drainage planning, more edges and more coordination with residents. Ask bidders to price the tear-off to deck separately, since many buildings here are older.

What is the minimum slope for a new flat roof in Miami-Dade?
In the Miami-Dade High-Velocity Hurricane Zone, which covers Ojus, new decks must be built with at least 1/4 inch of slope per foot. The rule covers single-ply, modified bitumen and built-up roofs. In Ojus, where 59.5 percent of homes are in buildings of 10 or more units, that slope matters for drainage on large flat roofs. Ask the bidder to show the slope on the drawings and explain how water reaches the drains within 48 hours.

What should I check on a commercial roofing bid in Ojus?
Look for the Miami-Dade product approval for every material and a clear statement on tear-off versus recover. Confirm the contractor holds the state roofing certification and that the proposal names the permit path. In Ojus, where 78.4 percent of units predate 1980, a recover is barred if the existing roof is water soaked, has two or more prior coverings, or has blisters left uncut.
