Commercial Roof Repair in Tempe, AZ
Flat-roof retail, office, and multi-unit buildings serviced with minimal disruption to tenants and customers.
A leak on a commercial roof is a business problem, not just a building problem
When a retail store, office, or multi-unit building has a roof issue, the stakes go beyond the building itself — tenant complaints, inventory damage, and disrupted business hours all add pressure to fix it fast and fix it right. Commercial work can usually be scheduled around your operating hours; ask the contractor to confirm the plan so there are no surprises for you or your tenants. Most East Valley commercial buildings run TPO, EPDM, or modified bitumen — see our flat roof repair page for a deeper look at low-slope systems.
Property managers with several buildings or units can use one request for all of them — one point of contact instead of juggling multiple vendors. Read more about how we work with property managers across the East Valley.

Commercial roof types, and where each one fails
Most commercial buildings in Tempe have one of these low-slope systems. Each one leaks in its own predictable places, which is where an inspection starts.
| Roof system | Where it usually fails | Usual repair |
|---|---|---|
| TPO | Seams that were not fully welded, and punctures from foot traffic around equipment | Clean and heat-weld a patch, add walkway pads at service paths |
| EPDM (rubber) | Seam tape letting go, and shrinkage pulling the membrane away from walls | Re-seam, add a cover strip, reflash the perimeter |
| Modified bitumen | Cracked seams, blisters, and granule loss on the cap sheet | Cut out blisters, torch or cold-apply a patch, recoat |
| Built-up (BUR) | Alligatoring, blisters and bare felt where gravel has washed away | Patch with new plies, reflash, restore the surface. See built-up roof repair |
| Sprayed foam (SPF) | Worn coating, bird pecks and blisters | Spot repair the foam and recoat. See foam roof repair |
Commercial roof repair cost in Tempe, AZ
These are typical ranges for planning. Roof size, access, the system you have and whether wet insulation needs to come out all change the number, and you get it in writing before work starts.
| Repair | What it involves | Typical range |
|---|---|---|
| Leak repair in one area | Find the entry point, patch the membrane or seam, check the deck below | $400 to $1,500 |
| Parapet, curb or drain flashing | Reflash where the roof meets walls, HVAC curbs or drains | $500 to $2,000 |
| Ponding water fix | Add drainage or build up low spots that hold water | Priced at inspection |
| Restoration coating | Repair, clean and coat a sound membrane to extend its life | About $2 to $5 per sq ft |
What Tempe weather does to commercial roofs
- Heat and UV. Roof surfaces in a Tempe summer can run far hotter than the air. Membranes dry out, seams work loose, and coatings chalk away.
- Ponding water. Flat roofs that hold water after a storm age faster at those spots. See ponding water on flat roofs.
- Parapets and coping. Many leaks that show up inside start at the top of a parapet wall, not on the roof field. See parapet and coping failures.
- Rooftop equipment. HVAC units, swamp coolers and conduit cut through the membrane, and service traffic damages the roof around them.
- Monsoon wind and debris. Gusts lift membrane edges and flashing, and haboob dust clogs drains and scuppers right before heavy rain.
Twice-a-year commercial roof inspections
Most commercial leaks start small, at a seam, a drain or a piece of flashing. A spring inspection before the summer heat and a fall inspection after monsoon season catch these while they are still a small repair.
Each inspection covers seams, flashing, drains and scuppers, rooftop equipment and any ponding areas, with photos and a written list of what needs attention. If a leak does happen, our commercial roof leak response plan explains what to do first to protect tenants and inventory.

Commercial roofing questions
Can work be scheduled around our business hours?
Yes — roofers in our network work with retail, office, and multi-unit property managers to schedule repairs during off-hours or in phases to minimize disruption to tenants and customers.
Do you handle multi-property accounts?
Regularly. Landlords and property managers with several buildings or units can use one request for all of them.
What commercial roof types do you service?
Mostly flat and low-slope systems common on retail, office, and multi-unit buildings — TPO, EPDM, modified bitumen, and built-up (BUR) membrane roofing, plus sprayed foam roofing on older buildings.
Does Tempe's heat affect which commercial roofing material is best?
Yes. TPO's white, reflective surface handles Arizona's summer heat and UV exposure well and can lower cooling costs, while EPDM's dark membrane absorbs more heat but holds up well against monsoon hail and foot traffic. Ask the roofer to walk you through which system fits your building and budget during the inspection.
How much does commercial roof repair cost in Tempe?
A leak repair in one area often runs $400 to $1,500, and flashing repairs at parapets or curbs $500 to $2,000. Larger jobs such as a restoration coating are priced by the square foot after an inspection.
Should a commercial roof be repaired, coated or replaced?
If the membrane is mostly dry and sound, repairs plus a restoration coating can extend its life at a lower cost. When wet insulation is spread across much of the roof, replacement is usually the better long-term choice.
How often should a commercial roof be inspected?
Twice a year is a good rule in the Valley: once in spring before the summer heat and once in fall after monsoon season, plus after any major storm.
