Commercial Roofing
A soft spot near a roof drain can point to wet insulation, a damaged cover board, or a deck condition that needs a closer look. In Edinburg, TX, we inspect those layers before adding insulation or closing them beneath a new membrane. The Rio Grande Valley's long heat-safety season makes roof-surface exposure part of the assembly decision, while Hanna's flooding and shingle-loss reports in Edinburg reinforce the need to understand drainage as well as thermal performance. We map what is dry, what is uncertain, and what needs removal. Then we compare insulation thickness, slope, cover board, and attachment with the existing roof and building use.
We review the roof plan and look for changes in elevation, old patches, soft areas, and water marks before selecting a test location. A probe or approved opening can show the insulation type, the condition of the cover board, and whether the deck is sound. We photograph each opening and mark its position so the finding can be tied to a roof zone. A roof inspection can also compare interior reports with the surface conditions before we price insulation removal.
Cover board protects insulation from foot traffic, installation pressure, and damage at the membrane layer, but its suitability depends on the assembly and attachment. We check for crushed, split, loose, or water-affected boards and note whether they can remain. If the roof has several layers, we identify how each one connects to the deck and to adjoining areas. A recover assessment should establish that retained layers are dry and stable before new insulation or board is placed above them.
A tapered layout can guide water toward a drain or scupper when elevations, curbs, and overflow routes leave room for the added build-up. We map the low point, outlet location, and existing slope, then review where the finished surface will meet doors, walls, and equipment supports. A drainage correction may be needed if the bowl, overflow, or surrounding insulation is also part of the problem. The plan identifies the intended flow path instead of treating taper as a generic layer.
At a wall, skylight, curb, or perimeter, added height changes flashing and termination details. We calculate the transition with the assembly designer and confirm that the membrane can turn up to a suitable height without blocking equipment service or drainage. The deck and parapet also matter when the project adds weight or changes attachment. A perimeter review can coordinate new insulation height with coping, edge metal, and gutter connections before materials are ordered.
We compare the roof system, deck, attachment method, intended thermal performance, traffic, moisture condition, and project requirements before naming a board or insulation layer. Polyisocyanurate, mineral wool, and other products have different properties and uses; the right assembly depends on design and applicable requirements. Edinburg's adopted code list includes the 2018 editions of its building and energy codes. We confirm which provisions apply to the project rather than assume a particular thickness or fastening pattern. A TPO roof assembly needs compatible cover-board and attachment details.
Cover board may be mechanically fastened, adhered, or installed as part of a tested assembly. We coordinate the board joints, fastener layout, membrane attachment, and edge details so that seams do not stack in a way that weakens the roof surface. For an occupied building, the sequence also accounts for open zones, material staging, and temporary tie-ins. A replacement scope should explain what existing layers are removed, what remains, and how the new insulation meets the old at each transition.
We look at the deck type and attachment method before the board pattern is selected. A fastener must reach a suitable substrate, and an adhered assembly needs a surface prepared for the adhesive. Existing layers may alter pullout, bond, or alignment, so a sample check can be useful before the full field is installed. The detail drawings should resolve edge zones, curbs, and changes in roof height rather than leave those transitions to field adjustment.
Moisture beneath the membrane can reduce insulation performance and compromise adhesion or attachment. We map wet and dry areas, inspect the deck where approved, and extend removal until the boundary reaches material that can remain. If tests show a small isolated area, a sectional correction may be possible. If the wet material continues under equipment or across several bays, the repair can become a larger reroof decision. The repair scope names where removal stops and what was found below.
Local storm history informs what we check without serving as a diagnosis. A tropical wind record notes gust impacts in Hidalgo County, listing McAllen, Pharr, and Edinburg among the affected communities. After a report, we inspect for a lifted membrane or disturbed edge before deciding whether the cover board and insulation need replacement. Hanna's Edinburg reports also make it sensible to revisit low areas and drains after flooding. A photo condition record keeps test locations and retained sections clear for later maintenance.
Insulation that has stayed wet can remain heavy and lose its intended thermal role, while a dry layer may still be usable if it is attached and compatible. We use openings and readings to separate those conditions instead of replacing material only because the roof is old. When removal exposes a damaged deck or a different layer count than expected, we photograph it and revise the scope with the facility director before the new board covers the area.
We coordinate insulation installation with building operations, rooftop equipment, and weather protection. Only the area that can be made watertight within the work window is opened. The crew stages boards so drains remain accessible, keeps loose material contained, and confirms that temporary tie-ins are secure before leaving. If equipment must stay in service, we plan around its clearances and keep access paths available where safe. The facility director receives a sequence by roof zone and a daily stop point.
Closeout records the insulation type and board installed, attachment approach, tapered layout, repairs beneath the membrane, and details that still need periodic inspection. The heat-safety period in the Valley extends from May into October, so the assembly also needs a maintenance plan for penetrations and areas exposed during rooftop service. For a project in the Edinburg service area, we can set a repeat inspection route that revisits drains and transitions after other trades work on the roof. The record ties thermal and drainage choices to conditions in the finished assembly.
Only after we confirm that retained layers are dry, secure, compatible, and suitable for the planned attachment. Testing may show that local removal is needed before new insulation and cover board can be installed.
It provides a more durable surface above insulation and below the roof membrane, subject to the selected system. We choose its type and attachment with the membrane, traffic, substrate, and project design in view.
It can redirect water when the roof elevations and outlets allow a workable slope. We map the low area and finished heights first, including curbs, drains, and overflow paths that could be affected.
We use test openings and moisture observations to distinguish affected material from dry layers. The report marks each location, then the scope stops at sound material or expands when additional wet insulation is exposed.
Yes, when the assembly can be tied in securely and each area can be protected from weather. We sequence removal, board placement, membrane work, and equipment access by roof zone.
