TPO Roofing
Welded TPO turns up the parapet as one piece with the field sheet, and the welds at corners and scuppers can be probed for gaps.

Parapet Roof Building
Coping Install
Scupper ClearingParapets Decide How A Flat Roof Drains
A flat roof boxed in by parapet walls can only drain where someone cut an opening. When a scupper clogs or the parapet flashing lets go, water has nowhere to go but down into the wall or the building.
Clarkdale's Building Division requires a permit for roofing work of any size, so even a parapet rebuild goes on file before work starts.

- Base flashing where the roof meets the wall
- Scupper openings and the flashing around them
- Inside corners where two parapets meet
Parapet Roof Problems And Fixes
Most flat-roof leaks on parapet buildings start at the wall. Here is how each one shows up and what we do.
Damp spots high on an inside wall
Likely CauseOpen joints between coping caps letting rain run into the top of the parapet.
What We DoWe pull the coping, reseal or replace the joint covers, and refasten the caps.
Water standing against one wall
Likely CauseA scupper choked with leaves, juniper litter, or dust, or an opening set too high above the roof.
What We DoWe clear the scupper, check its height against the low point, and add an overflow where water still backs up.
Leaks at a building corner
Likely CauseInside corners where two parapets meet are the hardest spot to flash and the first to split.
What We DoCorners get new preformed flashing welded or taped into the field membrane.
Membrane pulling away at the wall
Likely CauseBase flashing that has shrunk or lost adhesion opens a gap where the roof turns up the parapet.
What We DoWe strip the failed base flashing, prime the wall, and install new flashing with a termination bar.
Cracked stucco or brick on the parapet
Likely CauseWater inside the wall freezes on winter nights and pushes the finish apart.
What We DoWe stop the water at the coping and flashing first, then hand masonry or stucco repair to the right trade.
Why Clarkdale Owners Fix Roofs Early
Parapet leaks spread inside walls before they show on a ceiling. Catching them early keeps the repair up on the roof.
Before The Work
- Rain entering through open coping joints
- Scuppers backing water against the wall
- Split flashing at inside corners
- Base flashing pulled away from the parapet
- Wet insulation along the roof edge
After The Work
- Coping caps reset with sealed joint covers
- Scuppers cleared, with overflows where needed
- Corners wrapped in new preformed flashing
- Base flashing reinstalled under a termination bar
- Dry insulation and a tight edge detail
Clarkdale Roof System Options
TPO and EPDM both handle flat roofs boxed in by parapets. The difference shows at the wall details.
EPDM Roofing
Rubber sheets bend into tight parapet corners and stay pliable through freezing nights, with taped seams and cover strips at every turn.

Call and tell us which wall it collects against. A blocked scupper is the usual cause, and clearing it is often the first repair.
Call UsHow A Clarkdale Parapet Roof Job Runs
Inspection comes first, the town permit follows, and parapet details get fixed before the field of the roof.
Inspect Your Roof
Every parapet gets walked, coping joints are checked by hand, and moisture readings run along the edge where water tends to enter first.
Mark The Wall Details
Each coping joint, scupper, and corner is marked on a roof plan, so the repair list shows exactly which openings let water in.
File The Town Permit
Clarkdale requires a permit for roofing work, so the application goes to the Building Division with the scope before materials arrive.
Rebuild The Edge
Old base flashing is stripped, wet edge insulation replaced, and new flashing run up the parapet under a termination bar and reset coping.
Seal And Test The Openings
Scuppers are reflashed, corners wrapped, and every roof opening is checked with you on a final walk before the job closes out.

Clarkdale Roofing Questions
Answers about parapet roofs, scuppers, and permits for Clarkdale commercial buildings.
Do I need a permit to repair a parapet roof in Clarkdale?
Yes. The Town of Clarkdale Building Division states that roofing work needs a permit, whatever its size. We include the permit filing in the roof scope so coping, flashing, and membrane work can start once it is issued. Tell us early if the leak is urgent.
Where do parapet roofs usually leak?
At the edges. Coping joints, base flashing where the membrane turns up the wall, inside corners, and scupper openings all have seams or terminations that age faster than the flat field. Most parapet leak repairs happen within a few feet of the wall.
How do I know if my scupper is too small?
Water that stands against the wall for hours after a storm is the clearest sign. We measure the opening, compare it with the roof area it drains, and check whether it sits above the low point. An undersized or high scupper gets resized or paired with an overflow.
Can coping be repaired, or does it need replacing?
Loose or leaking coping can often be refastened with new joint covers and sealant. Caps that are bent, rusted through, or too short to cover the wall top get replaced, and the parapet top gets new underlayment before they go back on.
What causes cracks in parapet stucco or brick?
Trapped water is the usual cause. Rain gets in through open coping or failed flashing, then freezes on winter nights and pushes the finish apart. Fixing the roof side first stops the cracking from returning after the masonry or stucco repair.
Should a parapet roof be TPO or EPDM?
Either works well. TPO welds into one piece up the parapet face and at corners, and the welds can be probed. EPDM bends easily into tight corners and stays pliable in cold weather. The choice often comes down to how many corners and penetrations the roof has.
Can parapet work be done while the building is open?
Usually. Parapet and edge work happens at the outside of the roof, away from the rooms below. Material lifts are placed away from entrances, and any opened edge is sealed before work stops for the evening. Noisy coping removal can be scheduled for early or late hours.
