Flat Roofing overview
Flat roofs are not really flat. A well-built low-slope roof has just enough pitch to move water toward drains, scuppers, or gutters. When that slope is missing or the membrane fails, water ponds, finds a seam, and works its way inside.
You see these roofs all over Mercer County: rear additions, enclosed porches, attached garages, storefronts, and commercial buildings. Shingles do not work at low pitches, so these areas need a continuous membrane built to hold up to standing snow, ice, and heavy rain.
Leveled Up Construction installs and repairs EPDM, TPO, and modified bitumen roofs for homeowners and property owners in Sharpsville and Mercer County. We check the deck and the drainage first, explain which membrane fits your building, and give you a written estimate.
What Our Flat Roofing Work Includes
- 01
Tear-off and deck repair
We remove failed membrane and wet insulation, then repair or replace soft decking. Trapped moisture under an old flat roof is one of the main reasons new roofs fail early.
- 02
Insulation and slope
Rigid insulation boards go down over the deck, and tapered insulation can be added to build slope toward drains. Better drainage means less ponding and less stress on seams.
- 03
EPDM rubber roofing
EPDM is a durable rubber membrane that handles cold weather and sunlight well. It suits many residential additions, porches, and garages where large single sheets cover most of the roof.
- 04
TPO roofing
TPO is a white or light membrane with heat-welded seams, common on commercial buildings. The welded seams become a single sheet, and the light surface reflects summer heat.
- 05
Modified bitumen
Modified bitumen is a layered, asphalt-based roll roofing that is tough underfoot. It works well on smaller residential flat roofs and areas that see some foot traffic.
- 06
Edges, drains, and flashing
Most flat roof leaks start at the edges and penetrations. We detail drip edges, parapet walls, scuppers, drains, and where the flat roof meets a sloped roof or wall.
Signs Your Flat Roof Needs Attention
- ✓ Water stands on the roof long after the rain stops.
- ✓ The membrane has bubbles, blisters, cracks, or seams pulling apart.
- ✓ You see leaks or stains in the ceiling below the flat section.
- ✓ The roof feels soft or spongy when you walk on it.
- ✓ Flashing at walls or edges is loose, peeling, or torn.
- ✓ The roof has been patched many times and keeps leaking.
What Affects the Cost of a Flat Roof
Flat roofs vary a lot from one building to the next, so there is no honest flat price without getting up there and checking the deck. These are the factors that matter.
- Roof size
- A small porch roof and a large commercial roof are very different jobs. Square footage drives membrane, insulation, adhesive, and labor more than anything else.
- Membrane choice
- EPDM, TPO, and modified bitumen each have different material costs and installation methods. The right one depends on your building, how it is used, and your goals.
- Wet insulation and deck damage
- Old flat roofs often hide soaked insulation or rotted decking. All of it has to be removed and replaced, and the amount is only clear once the old roof is opened.
- Drainage corrections
- If the roof ponds, adding tapered insulation, new drains, or scuppers fixes the root problem. That adds work but prevents the same failure from happening again.
- Edges and penetrations
- Parapet walls, rooftop units, vents, skylights, and tie-ins to a sloped roof all need detailed flashing. More penetrations mean more labor and material.
