Flat Roof Repair & Replacement in The Villages, FL

Flat roof repair with NB Roofs starts by finding where water gets in, usually an open seam, a blister or failed flashing, then repairing the membrane in that area. When the membrane is worn across the roof or the insulation under it is wet, NB Roofs replaces the flat roof with a new modified bitumen, TPO, PVC or EPDM system.

What we do

Flat Roof Repair, Replacement and Maintenance

Many homes in The Villages and Central Florida have a flat or low-slope section that shingles cannot cover: a porch, lanai, carport or addition. NB Roofs repairs, replaces and maintains these roofs.

    Flat Roof Replacement

    A flat roof replacement removes the old layers down to the deck, dries out or replaces wet insulation and damaged decking, and builds in enough slope for water to drain before the new membrane goes on.

    • Modified bitumen, TPO, PVC and EPDM options
    • Slope and drainage planned before the membrane
    • Flashing at walls, curbs and roof openings

    Flat Roof Repair

    Flat roof repair fixes the place water gets in: an open seam, a tear or blister in the membrane, or loose flashing at a wall, curb or AC stand. Water can travel under the membrane, so the leak is traced before anything is patched.

    • Seams, blisters and tears repaired
    • Flashing at walls and roof openings resealed

    Flat Roof Maintenance

    A flat roof depends on its drains. Maintenance keeps drains, gutters and scuppers clear, checks seams and flashing before the summer rains, and catches small problems while they are still repairs.

    • Drains, gutters and scuppers cleared
    • Seams and flashing checked
    • A check after major storms

What a flat roof inspection looks at

  • Membrane and seams: tears, splits, blisters, open seams and worn areas.
  • Drainage: ponding water, low spots, and clogged drains, gutters or scuppers.
  • Flashing and penetrations: walls, curbs, vents and AC stands, where many flat roof leaks start.

Repair or replace

When is flat roof repair enough?

Flat roof repair is usually enough when the damage sits in one area, such as a split seam, a blister or loose flashing, and the insulation around it is dry. A flat roof usually needs replacing when the membrane is cracked or shrinking across the roof, the insulation is wet in several places, or leaks keep coming back.

Usually a repair

  • One leak in a single area of the ceiling
  • A small tear, split or blister in the membrane
  • A loose seam or damaged flashing at a wall, curb or vent
  • A clogged drain or scupper causing ponding water

Usually a replacement

  • Cracking, shrinking or worn membrane across large areas
  • Ponding water in many spots, or low areas that keep coming back
  • Soft or spongy spots that point to a wet deck or insulation
  • Repeated leaks in different parts of the building
  • Storm damage across large sections of the roof

Membrane still sound but worn by the sun? A roof coating may be an option. Damage after a storm? See storm damage roof repair.

Flat roof materials

What is the best flat roof material for Florida?

There is no single best flat roof material for every Florida home. Modified bitumen is a common, tough choice for porches and additions. TPO and PVC are white single-ply membranes that reflect sun and have heat-welded seams. EPDM is a rubber membrane laid in large sheets. The right one depends on the roof's size, drainage, foot traffic and budget.

What is TPO roofing?TPO (thermoplastic polyolefin) roofing is a single-ply membrane, usually white, that is fastened or glued to the roof and joined with heat-welded seams. The white surface reflects much of the sun, which helps keep the space below cooler.

  • Modified bitumen

    Asphalt-based sheets reinforced with polyester or fiberglass, applied in layers. Thick and puncture-resistant, a common choice for porches, carports and additions.

  • TPO

    A white single-ply membrane with heat-welded seams. Reflects sun and suits larger, open roof areas.

  • PVC

    A single-ply membrane like TPO, also heat-welded, with a long record on roofs that see grease or chemicals, such as near kitchen vents.

  • EPDM (rubber roofing)

    A synthetic rubber membrane laid in large sheets, so there are fewer seams. Usually black unless it has a white top layer or coating.

Built to drain

How is a flat roof replaced so water drains off?

A flat roof is never truly flat. The Florida Building Code calls for new membrane roofs to have a design slope of at least 1/4 inch per foot (2 percent), so a replacement is planned around where the water will go before the membrane goes on.

  1. Remove old layers

    Old membrane and wet insulation come off, so the deck can be checked for soft or rotted spots and repaired.

  2. Map the low spots

    Where water has been standing shows where the roof needs more slope, or a new drain or scupper.

  3. Build in the slope

    Tapered insulation boards, or a cricket at a wall, steer water toward the drains, gutters and scuppers.

  4. Install the membrane

    The membrane goes on as the manufacturer specifies, with seams heat-welded or sealed for that system.

  5. Flash every edge and opening

    Walls, curbs, pipes, AC stands and roof edges get flashing, because these joints are where most flat roof leaks start.

  6. Check the drainage

    Drains and scuppers are cleared and checked so water leaves the roof well within 48 hours of rain.

Flat roof lifespan

How long does a flat roof last in Florida?

InterNACHI's life expectancy chart lists modified bitumen at 20 years, EPDM at 15 to 25 years and TPO at 7 to 20 years, as guidelines. In Central Florida, drainage, sun and how quickly small repairs are made decide where a flat roof falls in that range.

  • Drainage

    Water that stays more than 48 hours after rain counts as ponding in the roofing industry glossary. It wears the membrane and seams faster, so clear drains add years to a flat roof.

  • Sun and heat

    Florida sun dries out and shrinks roofing membranes over time. White TPO and PVC, or a reflective top coat, take less heat than a dark surface.

  • Repairs and storms

    An open seam left alone lets water soak the insulation, and wet insulation shortens the life of the whole roof. A check after major storms keeps damage small. See storm damage roof repair.

Questions

Flat Roof Questions from The Villages Homeowners

  • What causes ponding water on a flat roof?

    Ponding water on a flat roof is usually caused by low spots, a sagging or damaged deck, wet insulation that has compressed, or clogged drains, gutters and scuppers. The fix depends on the cause: clearing drains, repairing the deck, or adding tapered insulation or a new drain so water runs off.

  • How long should water stay on a flat roof after rain?

    Not more than 48 hours. The roofing industry's definition of ponding is water that remains more than 48 hours after rain in drying weather, and the Florida Building Code defines positive drainage the same way. Water that sits longer points to a drainage problem.

  • How can I tell if the insulation under my flat roof is wet?

    Soft or spongy spots underfoot, blisters in the membrane, ceiling stains away from any seam, and a musty smell in the room below are common signs. A roofer confirms it by checking the area directly, and wet insulation is replaced, because it stays wet and rots the deck.

  • Can you patch a flat roof yourself?

    A small temporary patch can slow a leak until a roofer arrives, but it rarely lasts, and some patch products do not bond to TPO, PVC or EPDM. The safer step is to call for a repair. See roof leak repair for what to do while you wait.
