Flashing At Walls And Corners
Inside corners, parapets, and curbs get new primed flashing and corner patches, the details where rubber roofs give out first.

Fit Check
Is Your Roof Ready For EPDM?
EPDM fits low-slope roofs that move or carry lots of penetrations. Check your roof against both lists.
Good Fit
- Older low-slope deck that expands and contracts
- Dozens of pipes, curbs, and equipment stands
- Existing EPDM that still stretches and recovers
- Roof areas that need simple future patching
- Plans for white EPDM or a reflective coat
Fix First Or Choose Another System
- Wet insulation across large areas
- Old EPDM that has shrunk and pulled from the walls
- Heavy foot traffic paths without walkway pads
- Process exhaust that drops grease onto the sheet
- Sloped roofs that shed water better as metal
EPDM Problems
Where EPDM Roofs Leak On Older Buildings
Rubber sheet lasts a long time. Leaks on West Valley EPDM roofs start at the seams and the details around them.
Long drip line under a lap
Likely Cause
Seam tape or adhesive that dried out and released after years of heat.
What We Do
Clean and prime the lap, install new seam tape, and cover the end laps with a patch.
Leak at a pipe boot
Likely Cause
Pipe boot cracked at the collar, or a clamp that loosened in the sun.
What We Do
Replace the boot with a molded EPDM boot, prime the base, and tighten a stainless clamp.
Water behind the parapet flashing
Likely Cause
Wall flashing pulled down as the sheet shrank and the termination bar loosened.
What We Do
Install new wall flashing up the parapet, reset the bar, and seal the top under the coping.
Wet ceiling around a drain
Likely Cause
Drain clamp ring off its seat on the rubber, letting water track under the sheet.
What We Do
Remove the clamp ring, set new sealant and a target patch, and re-clamp the drain.
Hot ceilings under a black roof
Likely Cause
Black EPDM absorbing heat across the whole field during summer afternoons.
What We Do
Price a white EPDM sheet at replacement, or a reflective coating over intact rubber.
EPDM Options
EPDM Roof Work For Tolleson Buildings
Four EPDM jobs we take on, chosen by what the inspection finds.
New EPDM Over New Insulation
After a tear-off, tapered boards and cover board go down before the new rubber sheet, so water runs to the drains.
Seam And Patch Repair
Released laps, splits, and punctures on a pliable EPDM roof get cleaned, primed, and patched with matching rubber.
Tear-Off Of A Failed Roof
Shrunken or soaked EPDM comes off in sections, and the deck under each section is checked before new sheet goes down.
Repair Or Replace
Repair It Or Put On A New EPDM Roof?
Weigh your rubber roof against these six points.
| Roof Factor | Repair The EPDM | New EPDM Roof |
|---|---|---|
| Seams | Some laps released in one area | Laps failing across the roof |
| Sheet | Still stretches and recovers | Shrunk, cracked, or crazed |
| Walls and curbs | A few loose flashings | Sheet pulling away at every wall |
| Insulation | Dry in most cores | Wet over wide areas |
| Surface heat | Coat the black sheet white | Choose white EPDM at replacement |
| Roof age | Inside its 25 to 30 years | Past its expected life |
Before You Call
Rubber Roof Leaking At The Seams?
Send photos of the laps or the stain inside. We check whether your EPDM can take a seam repair or needs new sheet.
What To Have Ready
- Photos of open laps or stains
- Approximate roof age
- Number of pipes and curbs
- Past patch or coating work
- Hours the building is occupied
EPDM Process
How An EPDM Roof Job Runs
This is how we take an older Tolleson building from a leak to a tight rubber roof.
Step 1: Inspect Your Roof
Every lap, boot, and wall flashing gets checked, and cores show whether the insulation under the rubber is dry enough to keep.
Step 2: Clear Drains And Scuppers
Dust and debris come out of drains and overflow scuppers first, so the roof drains while seams are opened and repaired.
Step 3: Prime And Tape Seams
Laps are cleaned, primed, and sealed with seam tape rolled down hard, and end laps get cover patches where water collects.
Step 4: Flash The Details
Walls, curbs, pipes, and drains get new primed flashing and molded boots, since those spots leak first on rubber roofs.
Step 5: Check And Document
After a water check at the repaired areas, you receive photos of each seam and detail plus notes on what to watch.

Roof Systems That Pair With EPDM
Two other systems we compare against EPDM during an inspection.
TPO Roofing
Large open warehouse roofs with few penetrations often go to TPO instead, with welded laps in place of taped seams.

Commercial Metal Roofing
Sloped shop roofs shed water better as metal, and retrofit framing can turn a leaking flat roof into a metal one.

Questions For A Tolleson EPDM Roofing Contractor
When does an EPDM roof make sense in the West Valley?
EPDM fits buildings that need a flexible, forgiving sheet: older roofs crowded with penetrations, or decks that move as temperatures swing. Standard black EPDM absorbs heat here, so ask about white EPDM or a reflective coat, and expect careful detailing at curbs and drains because the seams are taped.
Can you repair a 20-year-old rubber roof?
Often. If the sheet still stretches and the insulation is dry, released seams and failed flashings can be redone with primer and tape. A brittle or shrunken sheet is past repair, and we will show you the core and the cracked areas.
Is white EPDM worth it in Tolleson?
For a roof over cooled space, a white top surface keeps the sheet cooler on summer afternoons than black rubber. The extra cost and the cooling effect depend on the building, so we price both sheets side by side.
Can a coating go over our EPDM?
Yes, when the rubber is intact and clean. EPDM needs a primer made for rubber before the coating, and open seams get taped first, since a coating will not hold a lap together.
Why does our EPDM roof leak only after storms?
Wind-driven rain from monsoon cells pushes water under loose wall flashing and open end laps that stay dry in light rain. We check those spots first, along with drains that back up when dust washes into them.
How are EPDM seams sealed?
Modern EPDM seams use primer and pressure-sensitive seam tape, rolled down hard. Older roofs often used liquid adhesive, which dries out over the years and is a common source of released laps.
