Setting the Standard in AZ Roofing Since 1993
An active commercial roof leak during business hours in Arizona creates three simultaneous problems: an immediate safety concern, an asset protection problem, and an operational continuity challenge. This is not the same situation as a residential roof leak. You have tenants, customers, employees, equipment, and inventory to manage while the building above them is failing. Lyons Roofing is available at 602-638-3135 (Phoenix) or 520-900-1442 (Tucson) 24 hours a day, 7 days a week for commercial roofing emergencies throughout Phoenix, Tucson, and the surrounding Arizona communities. Licensed under AZ ROC# 348074, fully bonded and insured, BBB Ethics Award winner and A+ rated, and a member of the Arizona Roofing Contractors Association. Here is what to do in the correct order.

Before protecting assets or documenting damage, determine whether the leak creates a safety hazard that requires immediate action. Water contact with active electrical equipment, electrical panels, servers, or lighting systems is a serious electrical hazard. If water is entering near any electrical component, turn off power to that circuit before any other action. Contact your building’s electrical service if there is any uncertainty about the safety of the electrical system in the affected area. This step takes priority over everything else.
Once immediate safety is confirmed, assess which areas of the building are affected and what the occupancy impact is. If the leak is isolated to a non-public utility or storage area, business operations may be able to continue with appropriate containment. If the leak is in a customer-facing area, employee workspace, or is threatening inventory or equipment, temporarily restricting or evacuating that section is the appropriate action. Make this decision based on actual safety and liability conditions, not assumption.
Take photographs and video immediately before moving any inventory, equipment, or assets. This documentation is your insurance record. Once you have documented the existing damage, move assets away from the affected area, cover equipment that cannot be moved with plastic sheeting, and use drainage mats or improvised containment to prevent water from spreading beyond the affected zone.
A commercial building leak requires parallel notification, not sequential. Notify the building owner or property manager if you are a tenant. Notify your commercial property insurer. Notify any tenants whose spaces are affected if you are the property owner. Notify employees about any access restrictions. The sooner these notifications happen, the sooner the full response can be coordinated. Most commercial property insurance policies require prompt notification after a loss event.
Call Lyons Roofing at 602-638-3135 (Phoenix) or 520-900-1442 (Tucson) immediately. Our commercial emergency team is available 24/7 and responds to active commercial roof situations throughout Phoenix, Tucson, and surrounding Arizona communities. We assess the situation, determine whether emergency on-site response before the storm passes is feasible and safe, and implement temporary waterproofing after conditions allow to stop water entry through subsequent storm events. Arizona’s monsoon season runs June 15 through September 30 and produces multiple storm events per week at peak season, meaning the interval between your emergency call and the next storm test may be measured in days.
According to the Arizona Department of Insurance and Financial Institutions, commercial property insurance generally covers sudden storm damage to building systems including roofing. File your commercial claim promptly. Your Lyons Roofing inspection report provides professional written documentation of damage extent, cause, and scope that supports the claim. For property managers with tenants whose operations were disrupted, document the business impact in writing for lease obligations and potential tenant claim management.
The operational complexity of a commercial roof leak during business hours in Arizona is distinct from a residential leak in several critical ways. First, the building may be occupied by people who are not your employees, including customers and third-party tenants, which creates liability exposure beyond property damage. Second, the building may contain inventory, equipment, or data assets that represent significant financial value that is separate from the structural damage. Third, business interruption has its own financial dimension: lost revenue during a closure or partial closure, and potential lease obligation questions if a tenant’s space becomes unusable.
The compounding factor in Arizona’s monsoon season is the interval between storm events. Unlike in climates where a single significant storm may occur monthly, Arizona’s July and August monsoon season produces major storm events every two to four days at peak season. A commercial roof that leaks in one storm without receiving temporary protection is virtually certain to leak again within the week. The first event’s damage compounds with the second, and the second with the third, until what was a manageable repair becomes a major capital expenditure.
In commercial lease structures, the roof is almost universally the building owner’s responsibility, not the tenant’s. Commercial tenants have an obligation to notify building ownership promptly when they discover any issue with building systems, including the roof. The practical reality of an active emergency during business hours is that the party who first discovers the problem, whether tenant or owner, should take immediate protective measures for safety and asset protection and then initiate the notification chain described above.
Property managers overseeing commercial buildings in Phoenix and Tucson should have Lyons Roofing’s emergency number available as part of their facilities management protocol. Waiting for building owner approval during a business-hours commercial roof emergency that is actively threatening inventory, equipment, or tenant safety is a decision that almost always costs more than the emergency repair itself.
What is the first priority when a commercial roof in Arizona starts leaking during business hours?
The first priority is safety and asset protection, not roof repair. Immediately assess whether any electrical equipment, servers, merchandise, or inventory is at risk from water contact. Create a safe perimeter around any active leak in areas where water could contact electrical systems or equipment. Then document the situation with photographs and video before making any changes to the interior setup. Call Lyons Roofing at 602-638-3135 (Phoenix) or 520-900-1442 (Tucson) for 24/7 commercial emergency response.
Should I close my Arizona business when the roof is actively leaking during a monsoon storm?
Whether to close depends on where the leak is located and what it is threatening. If the leak is in a non-public area such as a storage room or utility space, you may be able to continue operating with appropriate containment measures. If the leak is in a customer-facing area or is threatening electrical systems, safety equipment, or inventory that would create liability, temporarily closing or restricting the affected area is the appropriate action. Your lease agreement may also have provisions for tenant notification requirements when building systems fail.
Who is responsible for a commercial roof leak during a monsoon in Arizona, the tenant or the building owner?
Responsibility for commercial roof repair is generally established in the commercial lease agreement. In most commercial leases, the building owner or landlord is responsible for structural components including the roof. Tenants are typically responsible for notifying the building owner of any roof-related problems promptly. Reviewing your lease terms and notifying both the property owner and your commercial property insurer immediately after a monsoon-related commercial roof leak is the appropriate course of action regardless of which party is responsible for repair.
How do I document a commercial roof leak during business hours for an insurance claim?
Document immediately with time-stamped photographs and video of all water entry points, interior damage to contents and equipment, any business operations that were disrupted, and any safety measures you implemented. Note the date and time the leak began, the duration, and any prior complaints or maintenance requests made about the roof. Employee statements and customer-facing business disruption records may also support a commercial claim. Lyons Roofing provides a professional written inspection report with photographs that supports commercial insurance claims.
How do I protect inventory and equipment from an active commercial roof leak in Arizona?
Move inventory and equipment away from the leak area immediately if it can be done safely. Cover inventory and equipment that cannot be moved with plastic sheeting. Create drainage channels using floor squeegees to direct water away from equipment toward drains. Turn off electrical equipment in the immediate area of the leak if water contact is possible. These steps protect your assets during the active event and your insurance claim by demonstrating that you took reasonable steps to minimize the damage.
How quickly should a commercial roof leak in Arizona be repaired?
A commercial roof leak should receive professional attention within 24 to 48 hours of its discovery. Arizona’s monsoon season produces multiple storm events per week at its peak in July and August, meaning that a commercial roof that leaked in one storm is almost certain to leak again within days if not repaired or temporarily protected. Water that entered during the first storm continues to damage insulation, decking, and structural components during the interval between storms even when no additional rain is falling.
Does commercial property insurance cover monsoon-related roof leaks in Arizona?
Commercial property insurance in Arizona generally covers sudden roof damage from storm events including monsoon wind, hail, and wind-driven rain. Coverage for business interruption losses that result from the roof failure may also be available under your policy. What is typically not covered is damage that results from deferred maintenance or from a pre-existing condition that was not disclosed. Filing your commercial claim promptly after a storm event, with thorough documentation, gives the strongest position for maximum coverage.
Can I ask tenants to leave their space during an active commercial roof leak in Arizona?
If a roof leak creates an unsafe condition in a tenant’s commercial space, the property owner has an obligation to address the safety issue promptly. Tenants may have rights under their lease terms when a building system failure renders their space unusable. Consult your commercial lease terms and, if the situation is significant, consult with a commercial property attorney familiar with Arizona law. The immediate practical priority is resolving the leak and the safety conditions it creates, with legal and lease questions addressed in parallel.
What temporary measures stop water entry in an actively leaking commercial roof in Arizona?
From inside the building: contain water with absorbent materials, drainage mats, or improvised containment systems. From the roof after the storm passes: professional application of temporary waterproofing membrane or properly secured tarping over the affected area provides temporary protection against subsequent storm events. Temporary measures do not restore the roof to full performance and are always a bridge to permanent repair. Lyons Roofing provides emergency temporary waterproofing as part of our 24/7 commercial emergency response.
Should a commercial property manager call the roofing contractor directly or go through building ownership first?
In a genuine emergency where an active leak is creating immediate risk to building occupants, equipment, or inventory, contacting a licensed roofing contractor for emergency response is the appropriate immediate action and does not require building ownership approval in most situations. Simultaneously notifying building ownership and your commercial property insurer is the correct parallel action. Emergency temporary protection to stop active damage is rarely disputed after the fact.
How do I find the source of a commercial roof leak that started during an Arizona monsoon?
The source of a commercial roof leak is rarely directly above where water appears inside the building. Water enters through a failure point in the roof surface, travels along insulation, decking, or structural members, and appears inside at the lowest accessible point, which may be several feet or further from the actual entry. Professional diagnosis traces the path from the interior water appearance point back to the roof surface, evaluating all flashings, seams, drainage systems, and surface materials systematically.
What is different about diagnosing a commercial roof leak vs. a residential roof leak?
Commercial roofs are larger, have more complex drainage systems, more rooftop equipment penetrations creating additional vulnerability points, and are often flat or low-slope which means water can accumulate and travel extensively before appearing inside. Commercial building tenants also present a specific complication: the interior damage may be in a tenant space that is leased, meaning the damage presentation and access may involve coordination with multiple parties rather than a single homeowner.
Does Lyons Roofing respond to commercial roofing emergencies during Arizona monsoon season?
Yes. Lyons Roofing is available 24/7 for commercial roofing emergencies throughout Phoenix, Tucson, and surrounding Arizona communities during monsoon season and year-round. We prioritize emergency response because Arizona’s monsoon season produces multiple storm events per week, and the window between storms is often too short for a standard repair scheduling timeline. Call 602-638-3135 (Phoenix) or 520-900-1442 (Tucson) at any time.
What documentation does Lyons Roofing provide for commercial insurance claims after a monsoon leak?
Lyons Roofing provides a written professional inspection report documenting all identified damage areas with photographs, an assessment of the cause and extent of the water intrusion, and specific repair recommendations with scope of work. This documentation is formatted to meet the requirements of commercial property insurance claims and can be coordinated with your adjuster’s inspection to ensure all damage areas are documented before any scope determination is made.
How do I prevent commercial roof leaks from happening again during the Arizona monsoon season?
The most effective prevention for subsequent monsoon leaks is a professional post-storm inspection followed by targeted repair of all identified vulnerabilities before the next storm arrives. Longer term, a semi-annual commercial roof maintenance program that includes pre-monsoon inspection and drain clearing, and post-monsoon damage assessment, consistently reduces both emergency leak frequency and total roofing cost over the building’s life. Lyons Roofing provides commercial maintenance programs structured around Arizona’s specific monsoon season timing.
