Patch Over Patch
Mastic, roll roofing, and fabric patches stacked over the years each move differently in the heat. Their edges split apart, and water runs between the layers.
Older Built-Up Roofs
Flowing Wells Commercial Roof Repair
Commercial roof repair in Flowing Wells for older built-up roofs, where blisters, alligatoring, stacked patches, and worn drains decide what a repair can fix.
Flowing Wells Roofs
Built-Up Roofs With Years Of Patches
Many commercial buildings in Flowing Wells carry built-up roofs that have been patched for decades. Each patch was a different material, and the edges where they meet are where the next leak starts.
We sort a roof like this into what still holds, what needs repair now, and what needs a replacement plan, so the money goes where it lasts.
- Old patches checked for what they were made of
- Blisters cut and repaired where they leak
- Drain bowls, rings, and strainers rebuilt
What We Find
Typical Repairs On Flowing Wells Roofs
Aging built-up roofs show their age in a few predictable places. These six come first.
Broken Blisters
Blisters that crack open let water between the plies. Cutting them out, drying the area, and patching in layers stops the spread.
Alligatored Surface
Asphalt that has dried and cracked into small plates sheds water poorly. Small areas get resurfaced; large areas point toward a replacement plan.
Tired Drains
Old cast drain bowls lose their clamping rings and strainers. Water gets under the roof at the drain itself, and the leak shows near the middle of the room.
Base Flashing At Walls
Older base flashing at parapets shrinks and pulls away from the wall. The gap at the top lets water run behind the flashing.
Pitch Pans
Pitch pans around pipes and supports lose their filler as it shrinks and cracks. Refilling them, or swapping in modern boots, closes the opening in the membrane.

How It Runs
How We Repair An Older Flowing Wells Roof
Older roofs get an extra sorting step before any repair.
Inspect Your Roof
We walk the whole roof, note every old patch and blister, check each drain bowl and strainer, and take core cuts where readings show water.
Sort What Holds
Each area gets a call: holding, repair now, or plan for replacement. You get the sorted list with photos and a roof sketch.
Repair In Layers
Built-up repairs go back in layers with compatible asphalt materials, and drains get new rings, strainers, or bowls as needed.
Record The Roof
Repaired areas and remaining old patches are photographed and mapped, which makes the next inspection and any replacement easier to plan.

Flowing Wells Questions
Flowing Wells Roof Repair Questions
Who issues roofing permits in Flowing Wells?
Pima County Development Services, since Flowing Wells is unincorporated. Ask the county about thresholds before repair work involves the deck, drains, or rooftop equipment supports.
Is an old built-up roof worth repairing?
Often, if the insulation is mostly dry and the deck is solid. Core cuts answer that. Blisters, drains, and flashing repair well on built-up roofs; widespread alligatoring and wet insulation point toward replacement.
Why do old patches keep failing?
Because the materials are mismatched. Mastic, roll roofing, and fabric each expand differently in the heat, so their edges split apart and water runs between the layers.
Can you just add another patch?
Adding a patch over a failed patch traps the problem. The old material comes off down to solid plies, the area dries, and the repair goes back in layers that bond.
What does a drain rebuild involve?
Clearing the line, replacing the clamping ring and strainer, and reflashing the membrane into the bowl. Cracked cast bowls get replaced. A rebuilt drain usually ends the leak in the middle of the room.
How do I plan for an eventual replacement?
Ask for a condition report with the repair. It shows which areas still hold and which are failing, so you can budget the replacement for a year that suits the building.
How long will repairs on an older roof hold?
As long as the plies around them stay intact. Repairs on a roof with dry insulation and flexible plies hold for years, while repairs on a cracked, brittle surface buy time until replacement.
Should gravel be put back after repairs?
On gravel-surfaced built-up roofs, yes. Gravel protects the asphalt from sun, so it gets swept aside for the repair and spread back over the patched area.
