A roof leak affects the rooms, equipment and people below it. Plan repairs, restoration or replacement around the roof system and the way your Richardson building operates.
Water near a rooftop unit does not by itself identify the failed seam or flashing. On a low-slope roof, the membrane, equipment curbs, drains and perimeter details work together to keep the building dry. We examine the affected roof area and the likely path before narrowing the repair.
The condition below the surface matters to the larger decision. A coating cannot restore wet insulation or a weakened deck. A membrane repair needs compatible material and sound adjoining roofing. Replacement makes sense when the assembly has problems that surface work cannot reasonably address.
The building is part of that scope. Tenant entrances, sensitive interior uses, loading areas and rooftop service access affect how materials move and how the work is arranged. Start with the leak locations and how the property is used; we can discuss the roof from there.
The best next step depends on what can remain in service, not just on how the surface looks.
| Roof option | What needs to be true | What changes the decision |
|---|---|---|
| Localized repair | The damaged seam, flashing or membrane area can be tied into sound compatible roofing. | Wet layers, damaged deck or recurring defects outside the repair widen the scope. |
| Coating or restoration | The substrate is suitable, prepared and dry, with repairs completed and drainage addressed. | Incompatible surfaces, poor adhesion or saturated layers must be resolved first. |
| Replacement | The existing assembly cannot reliably support repair or restoration, or wider rebuilding is justified. | Removal, insulation, attachment, edge details and drainage become part of the new roof plan. |
GAF’s liquid-applied roofing manual requires wet insulation and damaged substrate to be addressed before coating.
The system determines the repair materials and connections. Each route develops the questions that matter for that kind of work.
TPO is a single-ply membrane joined with welded seams. Repairs involve the field sheet and the details around curbs, penetrations and edges. Aged surfaces need appropriate preparation before a compatible patch can be welded.

A coating system restores a suitable surface after failed details and wet materials are corrected. Preparation, adhesion, product compatibility and drainage determine whether it is a useful alternative to wider removal.

Low-slope repairs follow water entry and the way water leaves the roof. An obstructed outlet, membrane opening and sagging area need different solutions. Recurrent ponding may require drainage work beyond a patch.
Explore flat-roof repairRoofing work needs an access and protection plan that fits the property. Discuss operating constraints while the scope is taking shape.
Locate leak-affected rooms, occupied entrances, loading areas and equipment that needs continued service. Roof access and material delivery must fit these uses.
HVAC, electrical and other rooftop work can require separate trades. Their connections and access should be coordinated with the roofing sequence rather than disturbed independently.
The amount opened at a time, protection of exposed areas and the weather window affect the sequence. A phased project still needs a workable path for tenants and maintenance staff.
Commercial roof price depends on the assembly, not only the visible membrane area. Wet insulation replacement, deck repair, attachment, edge metal and drainage changes can materially alter the job. Equipment density and occupied-building access add work even on roofs of similar size.
Keep the roof’s material, past repair locations and relevant equipment changes together in the building file when they are available. Those records help a later inspection distinguish an isolated new problem from a connection that has been repeatedly disturbed. You can still request help when records are incomplete.
Define the affected detail and immediate repair need.
Account for preparation and necessary underlying repairs.
Price the new assembly and building logistics together.
Yes, when the existing system is a suitable substrate and moisture, failed details, adhesion and drainage have been addressed. Coating a roof with wet insulation or an unsound base leaves those problems underneath. The actual assembly determines whether restoration is practical.
No. Water there can involve roof membrane, curb flashing, equipment or its drainage. The inspection follows the likely entry and identifies where roofing work or another trade is needed.
Yes. Tell us how the building is used and which entrances, rooms or work areas need continued access. Those operating needs belong in the roof plan from the start.
Tell us the building location, where the problem is showing up and any operating constraints. Start with a free roof inspection and a discussion of the work.
