Lyons Roofing is available 24/7 for commercial roof emergencies in Chandler. For active leaks or storm damage threatening business operations, we prioritize immediate assessment and, where safe conditions allow, same-day temporary protection to stop water intrusion while permanent repair is scheduled.

The most common causes are drainage system blockages, particularly after pre-monsoon haboob dust deposits debris in drains and scuppers; flashing failure at HVAC equipment curb perimeters, where thermal cycling fatigues adhesion bonds over time; seam separation on aging TPO or modified bitumen membrane systems; and foam coating degradation that has progressed to the point of exposing the underlying foam substrate.

Water that enters a commercial roof rarely appears inside the building directly below its actual entry point. It travels along insulation, decking, or structural members before finding an exit through the ceiling. Our diagnosis traces the interior water evidence back through the roof assembly to the actual entry point, whether that is a failed seam, a flashing gap, or a penetration seal, rather than repairing only the location where water happened to appear inside.

Yes. Most commercial roof repair work is conducted entirely from the roof level and creates no interior disruption to tenants or business operations. We coordinate scheduling with property management or business ownership to work around operational hours where timing is a concern for Chandler commercial clients.

Our emergency response includes an immediate phone assessment, on-site inspection to identify the extent and cause of active water intrusion, temporary protection such as tarping or temporary membrane patching to stop ongoing entry, written documentation of findings for insurance purposes, and scheduling of permanent repair as quickly as conditions allow.

Haboob dust storms deposit significant debris in commercial roof drains, scuppers, and drainage channels, often without any accompanying rainfall. This debris accumulates over the pre-monsoon weeks, and when the first high-volume monsoon storm arrives, partially blocked drainage cannot keep pace with rainfall volume, causing water to pond on the roof field and stress every seam and flashing simultaneously. Pre-monsoon drain clearing is one of the highest-value preventive actions a Chandler commercial property owner can take.

Yes. Chandler’s technology and industrial properties along the Loops 101 and 202 corridors, including large-footprint facilities with significant flat roof area and extensive rooftop equipment, are within our commercial roofing service scope. We provide both routine and emergency repair for these property types.

Every commercial repair project includes written documentation of the diagnosed cause, the repair scope performed, and materials used. For storm-related repairs, we provide the photographed damage assessment most Arizona commercial property insurance carriers require to process a claim.

According to the Arizona Department of Insurance and Financial Institutions, sudden storm-related damage to commercial roofing from monsoon wind, hail, and wind-driven rain is generally covered under standard Arizona commercial property policies. Damage attributed to deferred maintenance is typically excluded. Lyons Roofing’s written inspection and repair documentation supports commercial insurance claims for Chandler property owners.

A repair addresses an identified, active problem, a leak, a damaged section, a failed seam. A maintenance visit is a scheduled, proactive service that includes drain clearing, minor sealant corrections, and condition inspection intended to catch developing issues before they become active leaks. Lyons Roofing provides both, and many Chandler commercial clients use scheduled maintenance specifically to reduce the frequency and cost of emergency repairs.

Yes. HVAC curb flashing failure is one of the most common commercial roof leak sources in Chandler, driven by the combination of wind loading on mounted equipment and the flashing transitions at every curb perimeter. We repair curb flashing, re-seal penetration points at conduit and refrigerant line entries, and correct drainage conditions immediately adjacent to rooftop equipment.

We repair TPO and other single-ply membrane systems, EPDM, modified bitumen, spray polyurethane foam and its elastomeric coating, built-up roofing, metal roofing on commercial and industrial structures, and pitched commercial roof systems including tile and shingle on retail and institutional buildings.

For multi-tenant commercial buildings, we coordinate repair timing with property management to minimize any disruption across tenant spaces, and provide documentation suitable for shared building ownership or management company records when repair costs need to be communicated across multiple stakeholders.

The City of Chandler Building Division may require permits depending on the scope of commercial roof repair work. Minor, localized repair typically does not require a permit, while larger-scope repair or any work affecting structural roofing components may. Lyons Roofing evaluates permit requirements for each specific Chandler commercial repair scope before work begins.

Yes. Lyons Roofing provides written workmanship warranty coverage on commercial repair work. Where repair work intersects with an existing manufacturer warranty on the roofing system, we use materials and methods compatible with maintaining that warranty wherever possible, and discuss any warranty implications with the property owner before beginning work.

Our repair approach addresses the diagnosed root cause, not just the visible symptom. A leak repaired only where water appeared inside the building, without correcting the actual failed seam or flashing that let water in, will recur. We trace every commercial repair back to its actual source before determining scope, which is the difference between a repair that lasts and one that requires a return visit.

Yes. For Chandler commercial properties with an unclear or long-standing leak history, we recommend starting with a full commercial roof inspection to establish a complete picture of roof condition before scoping repair work, rather than treating only the most recently reported symptom.

Yes. Hail impact on commercial roofing, particularly membrane and foam systems, can create damage that is not always immediately obvious without close inspection. We provide post-hail commercial roof assessment and repair, along with the documentation Arizona commercial property insurance claims typically require.

Non-emergency commercial repair requests in Chandler are typically scheduled for inspection within one to three business days, with repair work scheduled promptly following the written assessment and property owner approval.

Yes. Many Chandler commercial property owners transition from one-time repair to a scheduled maintenance program once they see the value of catching developing issues early. Ask about our commercial roof maintenance program when scheduling your repair.
