A leak beside an HVAC unit often begins where flashing meets a curb, not in the middle of the membrane. At a commercial building, that transition has to move with the assembly while keeping water outside and equipment serviceable. We inspect the curb, membrane tie-in, counterflashing, nearby seams, and drain path, then mark the repair boundary and any area that needs opening or testing. That gives facilities staff a scope connected to the actual entry detail and a plan for protecting the unit below.
Share the leak location, roof plan, equipment contact, access procedure, and any recent curb or wall work. We will trace the transition, record the repair boundary, and coordinate a safe inspection window.
Review equipment curbs, pipes, conduits, wall intersections, skylight frames, parapets, expansion joints, and changes in roof level. Look for splits, loose termination bars, failed sealant, open corners, cracked boot material, and membrane pulling away from a vertical surface. Sealant may be part of a detail, but adding a bead over a moving or wet joint does not restore the flashing assembly. A penetration flashing inspection can record the curb or frame, the adjacent membrane, and any water path that reaches the interior.
On a low-slope roof, inspect the uphill side of each curb and the lower edge where water or debris can collect. If the penetration was added after the roof, compare its detail with the current assembly and available plans. Record any abandoned conduit or support rather than sealing it without knowing whether it remains in use. A equipment curb review can coordinate the roof detail with the mechanical contact before a repair interrupts service.
Movement at a wall or curb can pull on a flashing corner even when the field membrane remains intact. Photograph the junction from two directions and include a wider view that shows nearby drains or transitions. That context helps distinguish a local split from a path that continues beneath the field sheet, and it tells the crew whether the repair needs access from the wall side as well as the roof.
Record the room, ceiling condition, time, and recent weather, then compare the symptom with accessible roof details above and upslope. Water can follow a deck joint, conduit, or framing member before it appears indoors. We check flashing, seams, drains, and nearby transitions, and note where equipment blocks the inspection. A roof leak investigation can follow that path and identify whether a local repair is supported or a test opening is needed.
Pearland’s SH 288 healthcare corridor includes hospitals and specialty providers, while Broadway/FM 518 serves healthcare, retail, dining, schools, and service properties. Those occupied uses make interior protection and access coordination part of a flashing repair. A Iowa Colony commercial area area inspection should be arranged with the specific building contact, who can identify sensitive rooms and mechanical service windows. A roof inspection identifies the conditions and transitions at the building itself.
Water can collect or change direction at a curb, wall, or penetration, so inspect whether it stands against the flashing, whether an overflow path is clear, and whether the detail has prior patches. The roof walk should document the material condition, extent of separation, and any location that remains concealed until the curb or wall detail is opened. The field record should show the material condition, the extent of separation, and any location that remains concealed until the curb or wall detail is opened.
After a major rain, document active leaks and temporary covers before they are altered. If the repair crosses a parapet or coping, inspect how the vertical termination meets the horizontal roof surface and edge metal. A wind damage review can be useful when the same event moved metal or opened an edge, while a rapid roof response can address urgent water entry once safe access is confirmed.
A local correction can work when the curb, wall, or penetration is stable and the adjacent membrane remains sound. We remove failed material as needed, prepare the substrate, and tie new flashing into a compatible roof system. The detail may require a new boot, reinforced corner, termination, or counterflashing rather than surface sealant alone. If corrosion, movement, moisture, or repeated repairs extend beyond the transition, the scope needs broader review.
For recover or replacement work, preserve the flashing design across new insulation, cover board, and membrane thickness. The added height can change curb elevations, wall terminations, and door thresholds. A recover evaluation should account for those changes before the existing detail is covered. If a seam has also opened beside the flashing, inspect it separately and define both repairs; a seam repair may be needed at the adjoining field connection.
Share the leak location, roof plan, equipment contact, access procedure, and any recent curb or wall work. We will trace the transition, record the repair boundary, and coordinate a safe inspection window.
Keep the marked plan, close-up photos, material information, repair limits, and follow-up notes with the building’s roof file. Record any curb or unit that could not be reached and the mechanical contact needed for a return visit. Note whether temporary protection remained after the permanent work. That makes it clear what was repaired and whether the next service visit should check the same transition or another roof section.
Pearland Town Center combines stores and dining with hotel, residence, office, and training uses. A roof visit at a mixed-use property should account for public entrances, deliveries, guest schedules, and tenant contacts by building. Before we walk the roof, send recent leak locations, access rules, equipment contacts, and available roof plans. We can coordinate an inspection window and return findings organized for the property’s operating schedule.
A flashing repair needs a defined termination at both ends. Trace the connection from the roof field up the wall, curb, or penetration, and note where water could pass behind a loose edge. Check the substrate and adjacent membrane before removing metal or sealant; a new surface bead cannot restore a failed lap or attachment. The scope should identify removal limits, replacement metal or membrane, fastening, corners, end dams where needed, and how the detail returns to sound material. Photograph concealed conditions while open and record any change from the original scope before extending work. When several wall or curb details are nearby, label each one separately so the closeout does not imply every transition was repaired. The facility contact can then prioritize any inaccessible detail or interior follow-up.
Only if the detail is designed for sealant and the substrate is sound, dry, and prepared. A separated boot, unstable curb, or failed membrane tie-in needs the correct flashing repair rather than another surface bead.
Water can travel through the roof assembly or along framing before reaching a ceiling. We compare the interior report with accessible curbs, seams, drains, and wall transitions to identify the likely route and any test needed.
A unit change can alter the curb, height, or attachment. Coordinate the equipment dimensions and roof detail before setting the replacement so the flashing can be completed and inspected as part of the work.
We agree on roof access, equipment service, protection below, noise, and the daily dry-in point with the property contact. If the curb serves an active system, its shutdown window must be confirmed before work begins.
Several failures can point to movement, age, material incompatibility, or an assembly condition that reaches beyond isolated details. We map each location and compare the findings before recommending a larger repair or replacement scope. The roof record should group repairs by building and system.
Call 555-555-5555 or send the property address, roof area and what you are seeing inside. We will set up a roof walk.
