Roof Symptoms
Hammond TPO Roofing Starts With These Roof Signs
Most TPO jobs we bid replace an older roof that shows one of these patterns inside and up top.
Stains Spreading Across Warehouse Ceiling Tile
Inside The Building
Rings widen over aisles after each storm, then dry out and return with the next one.
On The Roof
Open laps on an aging membrane and insulation that soaks up water and moves it sideways.
Hot Top Floors In Summer
Inside The Building
Offices under the roof stay warm late into the evening while rooftop units run hard.
On The Roof
A dark, worn surface absorbing heat, with thin or crushed insulation underneath.
Puddles Days After Rain
Inside The Building
Facility staff report a damp smell near one wall after every heavy storm.
On The Roof
Ponding rings at mid-span where the deck has sagged and water never reaches a drain.
Slow Interior Drains
Inside The Building
Roof leaders back up and splash at the floor drain during downpours.
On The Roof
Drain bowls set low under old patches and baskets packed with gravel from a past roof.
Choices On This Roof
TPO Roofing Choices For Hammond Buildings
Four decisions shape every TPO roof we put on. Each one is made from the core cuts and the building below.
TPO Roof Over Existing Roof Or Tear-Off
One dry existing roof and a firm deck allow a recover with a cover board. Two roofs, or wet insulation in the cores, mean tear-off down to the deck.
TPO Roofing In Cold Weather
Mechanically fastened TPO goes on in winter; adhesives wait for their temperature range. Seams are welded only on a clean surface free of frost.
Membrane Thickness
Sixty-mil membrane covers most roofs. Eighty-mil goes where foot traffic, hail exposure, or long service life justify the extra cost.
Walkway Pads To Units
Welded pads mark the path from the hatch to each rooftop unit, keeping tools and boots off the field membrane.
What Changes
What A New TPO Roofing System Does For Hammond Warehouses
The change shows up inside the building first. These four come straight from the membrane and the layers under it.
Seams Welded Into One Sheet
Hot air fuses each lap into the membrane, and every weld is probed before the crew moves on, so the laps that leak first on older roofs become the strongest line.
A Cooler Roof Surface
White TPO reflects much of the summer sun that a dark roof absorbs, which keeps the deck cooler and eases the load on rooftop units over long July afternoons.
Fewer Laps On Big Roofs
Wide rolls cover a warehouse field with fewer seams per square, and less lap length means fewer places for water to find its way under the sheet.
Patches That Weld In Clean
Years later, a punctured spot gets a matching TPO patch welded over it, with no adhesive cure time, so a repair can close the same afternoon it is found.
Old Membrane Splitting At The Laps?
Get core cuts and a TPO scope before the next freeze opens those laps wider.
How The Work Runs
How A Hammond TPO Roofing Job Runs
A TPO replacement moves across the roof in sections so the building stays dry each night.
Cores And Roof Survey
Core cuts read the layers and moisture, and drains, curbs, and edges are measured so the scope covers every detail the new membrane meets.
Tear-Off Or Cover Board
Wet or doubled roofs come off to the deck; a firm single roof gets a cover board fastened over it before insulation.
Fasten, Lay, And Weld
Insulation is fastened, membrane rolls out across it, and seams are hot-air welded, then probed along their full length.
Flash, Pad, And Walk
Curbs, pipes, and edges get TPO flashing and metal caps, pads run to each unit, and the roof is walked with you.

TPO Roofing Questions From Hammond Owners
Can TPO roofing be installed over an existing roof in Hammond?
Over one dry layer
Yes, over one existing roof with dry insulation and a firm deck. Core cuts or a moisture survey come first, since wet boards sealed under new membrane keep rotting. Several old roofs or a damaged deck mean tear-off.
Can a TPO roof last 30 years in Hammond?
With thickness and upkeep
Twenty to thirty years is the common range. Thicker 60- or 80-mil sheet, well-welded seams, full drainage, and yearly checks push it toward thirty. Ponding, heavy traffic, and skipped inspections pull it back.
What are the downsides of TPO roofing for Hammond buildings?
Punctures and weld quality
Dropped tools and boots can puncture it, so service paths need pads. Membrane formulas differ between makers. Seams are only as good as the welding, which is why every weld is probed after it cools.
Why is TPO common on Hammond rail-served warehouses?
Wide, flat, reflective
Warehouse roofs there run wide and flat, and TPO comes in wide rolls with welded seams, so a big field gets fewer laps. The white surface stays cooler in summer, and a damaged section patches cleanly.
What happens to a Hammond flat roof when spring hail hits?
Check seams and insulation
Hail can crack aging seams, bruise the insulation under the sheet, and puncture thin membrane, and much of it hides from the ground. After a storm the roof is walked, soft spots are marked, and photos are taken in case an insurance claim follows.
Does a white TPO roof change rooftop unit loads?
Less heat on the roof
A white surface reflects much of the sun a black roof absorbs, so air around rooftop units runs cooler on summer afternoons. Units still need their own maintenance, but they work against less heat rising off the membrane.
