Spray polyurethane foam, or SPF, creates a continuous insulated surface, but its long-term condition depends on the foam profile and protective coating above it. A building in the Lower Kirby district may have active process equipment that affects roof access, while a property along SH 288 may need a tighter work window around tenants or clinical operations. We inspect the foam and coating as one assembly, checking drainage, penetrations, exposed areas, and prior repairs before recommending maintenance or a larger scope.
Send prior foam and coating records, roof plans, leak locations, equipment layouts, and site access rules. We will inspect the foam, coating, drainage, and penetrations by section and document the supportable next steps.
We look for exposed foam, erosion, cracks, blisters, gouges, splits, ponding depressions, and areas where the surface profile no longer directs water to an outlet. Foam thickness and contour can vary, so the review maps transitions and low points rather than relying on a general impression. Where coating has worn through, ultraviolet exposure may have changed the foam surface. The report should identify the condition and area, not assume that every exposed spot has the same depth or moisture below it.
Repairs require clean, dry substrate and a compatible foam or coating detail. Cutting out damaged foam can reveal whether the defect is shallow or extends into the assembly; any opening must be closed and photographed. A commercial roof inspection can record representative profiles, repair areas, and locations that need testing. If records list a particular system, compare them with field conditions before specifying a material.
The coating shields SPF from sunlight, weather, and service wear. We inspect adhesion, thickness where measurable, cracking, erosion, ponding wear, and separation at laps or terminations. Granules or other surfacing may be part of the selected coating design and should be checked for displacement. At a transition from a roof field to parapet or curb, coating continuity alone does not prove that the flashing detail beneath it is sound.
Recoat planning starts with adhesion and substrate condition. A representative test can help evaluate compatibility, but it does not replace a review of the full roof. The distinction between an acrylic and silicone coating matters because water exposure, surface preparation, and recoat requirements differ. We identify the existing coating where possible and document any uncertainty before pricing a new layer.
An SPF roof is shaped during application, so its contours and drain paths matter to performance. We mark depressions and measure ponding where it occurs, then check whether drains, scuppers, or gutters are clear and properly connected. HVAC work, added platforms, or later repairs can create new obstructions or low points. The inspection considers the roof shape and outlet together instead of treating every water mark as a coating defect.
Houston-Port reference station has a 54.12-inch annual precipitation normal and an August mean daily maximum of 94.3 degrees. Beryl’s 7.64-inch rainfall mark came from a gauge 4.1 miles northeast of Pearland. These numbers describe regional conditions; the roof itself needs to be inspected. A drain review can document blocked outlets or drainage concerns, and after heavy rain the owner can compare mapped ponding with interior reports.
Pipe supports, curbs, ducts, conduit, and roof-mounted supports interrupt the foam surface. We check whether the flashing is bonded to sound material, whether the coating terminates cleanly, and whether movement has opened a crack at the penetration. When new mechanical equipment is planned, the support and curb detail should be resolved before the SPF is cut. A curb and support assessment can coordinate roof details with the mechanical contractor and identify what access the unit requires.
Lower Kirby includes research, manufacturing, life-sciences, technology, and office uses. The facility contact can clarify operating restrictions, escorts, and whether equipment must remain active during the visit. If a process exhaust or service route has changed, note its location and condition so future maintenance can compare the same detail.
Send prior foam and coating records, roof plans, leak locations, equipment layouts, and site access rules. We will inspect the foam, coating, drainage, and penetrations by section and document the supportable next steps.
A localized gouge or failed flashing may be repaired if the surrounding foam remains adhered, dry, and sufficiently thick. Isolated coating wear may be a maintenance item when preparation and recoat compatibility are established. Broader erosion, widespread adhesion loss, repeated patch failure, wet substrate, or an unsuitable drainage profile can make a larger section scope necessary. We identify the evidence and the boundary of each recommendation, including where concealed conditions have not been tested.
Where the assembly no longer supports a reliable restoration, compare removal and replacement with another system such as TPO roofing. If the roof remains suitable for SPF, the work scope should state foam repair depth, surface preparation, coating selection, reinforcement at details, and finish thickness. A repair plan that only says “recoat” does not describe how damaged foam or flashing will be addressed.
Spray work requires staging for equipment, protection from overspray, weather monitoring, and control of access near the application area. The site plan should identify air intakes, vehicles, walkways, and neighboring operations that need protection. On SH 288, a medical, retail, or office property may need work scheduled around arrivals and building services. Confirm site-specific access and safety requirements before the crew mobilizes.
Coating application depends on suitable surface and weather conditions. Agree on a stop point and temporary protection if a rain event or wind change interrupts the operation. Daily logs should note roof sections completed, material or lot information, measured conditions where specified, and areas held for inspection. The handoff should list any section awaiting cure or final review.
Retain installation and recoat records, product data, roof plans, adhesion test results, repair photographs, and drainage observations. Mark each repaired location and note whether the crew removed foam or only renewed the coating. Keep a log of inspections and reported leaks so recurring symptoms can be compared with earlier findings.
Before an evaluation, share equipment layouts, access procedures, prior coating information, and any moisture survey. If the specified coating or foam product cannot be verified, the scope should say how it will be identified. That information helps the next maintenance decision build on what was actually applied and tested.
An SPF inspection should look beyond the coating color. Map areas of cracking, blisters, exposed foam, impact marks, soft spots, and separation at penetrations or edges. Compare suspect areas with intact foam and check whether water can collect at the same location. A coating renewal is appropriate only if the foam and substrate remain suitable and the surface can be prepared to accept the specified materials. Damaged foam may need removal and replacement before coating. Record the preparation area and completed thickness or application details when they are part of the approved scope. Where test results or a core sample could change the repair boundary, identify that question before work begins.
Foam condition, coating maintenance, drainage, installation quality, and repair history all affect service duration. Inspection and recoat records provide a better basis for planning than age alone.
A localized defect may be repaired when the surrounding foam is adhered and dry and the repair materials are compatible. The work should restore the foam profile and protective coating, then document the repaired boundary.
Recoat timing follows coating condition and the requirements for the installed system. We check wear, adhesion, thickness where measurable, substrate condition, and drainage before setting a recoat scope.
Direct application is appropriate only when the existing substrate is suitable, stable, and prepared for adhesion. Concealed moisture or incompatible materials may require removal, and testing can clarify conditions that are not visible.
Map the affected area and inspect drains, contours, coating wear, and nearby penetrations. The assessment should separate an obstructed outlet from a low profile or substrate issue and recommend testing if the cause is not visible.
Call 555-555-5555 or send the property address, roof area and what you are seeing inside. We will set up a roof walk.
