The roof over your back porch holds puddles for days after every storm. Or the flat section over the Florida room has been patched so many times you’ve lost count, and the ceiling under it is stained again. A new flat roof installation in Sanford is starting to look like the real fix, but you want to know it’ll drain this time and not just leak in a new spot.
That’s a reasonable worry. Flat roofs get a bad name mostly because so many are put on without enough thought about where the water goes. You should know how yours will be built before anyone starts tearing it off.

Why flat roofs struggle in Sanford
A flat roof isn’t perfectly flat. It should have a slight slope that moves water to an edge, a gutter or a drain. Sanford’s summer storms drop a lot of rain fast, and any low spot holds it. Water that sits for more than a couple of days after a storm wears the surface faster and keeps testing every seam.
Shingles can’t fix that. Shingle manufacturers set a minimum slope for their products, and many porch and carport roofs are too flat to meet it. On those roofs, shingles let wind-driven rain back up under the rows. A low-slope roof needs a continuous membrane instead.
Then add the Central Florida sun, which dries and cracks older roofing, and the hurricane-season wind that pulls hardest at the edges.
Choosing a flat roof system
TPO is a single-ply membrane, usually white, with heat-welded seams. The white surface reflects a lot of sun, which helps keep a porch or a room under the roof more comfortable. Learn more about TPO roofing in Sanford.
EPDM is a black rubber membrane with seams sealed by primer and tape. It’s flexible and handles movement well.
Built-up roofing (BUR) is layers of roofing felt and asphalt, often finished with gravel. It’s more common on older and commercial buildings.
For most homes in Sanford, the choice comes down to TPO or EPDM. The deck, the drainage, the way the roof meets your house and what’s sitting on it all point to the right one, and you’ll hear the reasons.
Flat roof installation in Sanford, start to finish
Tear-off and deck check. The old roofing comes off so the deck can be checked. Wet insulation and soft or rotted wood get replaced, because a new membrane over a wet base traps the moisture.
Fixing the slope. Where water ponds, the fix is usually tapered insulation or small built-up sections called crickets that steer water toward the drains or the edge. This is the step that decides whether the new roof actually drains.
The membrane. Sheets are laid out and fastened or adhered, and every seam is welded or sealed. Seams are where flat roofs fail, so they get the most care.
Flashing at walls and pipes. Where the flat roof meets a house wall, the membrane runs up the wall and gets covered with metal flashing. Plumbing pipes and equipment curbs each get their own sealed flashing.
Edges and drainage. Metal edge trim goes on around the perimeter, fastened well for wind, with gutters or scuppers where the water leaves the roof.
Rain stops all membrane work, so installs here are scheduled around the forecast. Many smaller residential flat roofs take a day or two.
Fascia and the roof edge
The fascia board along the edge of a flat roof takes a lot of water, especially where an old roof didn’t have proper edge metal or the gutter overflowed. It often rots from behind, where you can’t see it. When the old roof comes off, rotted fascia can be replaced before the new edge metal goes on, so the new roof isn’t fastened to bad wood.
How it works with APC Roofing
- Book your free inspection. Call 407-270-1129 or request a free online estimate.
- Get a clear, honest assessment and estimate. If the roof can be repaired instead, you’ll hear that first. Our flat roof repair in Sanford page covers that work. Financing is available through Aqua Finance, Fortifi, Hearth and Home Run Finance.
- Your roof gets done and the site gets cleaned up. The crew cleans up the old roofing and debris before leaving.
A flat roof that ponds doesn’t fix itself. Water that gets through a worn seam soaks the deck and the ceiling below, and the longer it goes, the more wood has to come out.
Flat roof installation questions from Sanford homeowners
Can you put shingles on my porch roof?
Only if the slope meets the shingle manufacturer’s minimum. Many porch and carport roofs are too flat, and a membrane is the right choice for them.
Can a new flat roof go over the old one?
Sometimes, if the old roof is dry and the code allows it. If the insulation or deck is wet, it has to come out first.
TPO or EPDM for a home in Sanford?
Both work. TPO’s white surface stays cooler in the sun. EPDM is flexible and simple to repair. Your estimate will explain which fits your roof and why.
Do you install flat roofs on commercial buildings?
Yes. See our commercial roofing in Sanford page.
A flat roof that sheds water
The goal is a porch or addition you can sit under during the next summer storm without watching the ceiling. Call APC Roofing at 407-270-1129 to book your free inspection.
