A tenant improvement that adds a single exhaust fan or a new rooftop unit changes the roof, because every added curb is another termination to be flashed and another path for foot traffic. Chapel Hill supports company recruitment as well as existing and emerging businesses, and its business sites include coworking spaces, laboratories and office options, with small-business support, incentives and grants on offer. Spaces of those kinds can turn over and be fitted out, and each fit-out can reach the roof. We start a Chapel Hill walk by counting what is on the roof now and comparing it with what the lease and the plans say should be there.
A new tenant brings new equipment: an exhaust fan, a condensing unit, a vent, a conduit run or a satellite mount. Each one pierces the membrane or rests on it, and the work is often done by a trade that does not return to check the flashing. Over several tenants, a roof accumulates openings, patches and abandoned supports.
We number the penetrations on a roof plan, probe the termination at each and mark any that are abandoned and can be closed. Our rooftop equipment curb and support findings tell the manager which units rest properly and which sit on bare membrane. A short rule for contractors, with walk pads and a sign-in sheet at the hatch, prevents many punctures, and the plan gives the next contractor a map of what already exists.
Roof access control is part of the answer. Keys to the hatch, a sign-in sheet and a short written rule about walk pads and protection let a manager know who has been on the roof and what they did. When a leak appears, the log narrows the search to the visits before it, and the plan shows what each visit touched.
A laboratory generally exhausts more air through more stacks, and the discharge reaches the membrane. Fumes, heat and moisture can soften certain materials, stain others and wear seams where the plume lands. We ask what each stack emits and how it is directed, then check the membrane in its path. PVC is commonly chosen where chemical or grease exposure is expected, and protective pads or deflectors can reduce the load.
The interior has its own demands: air intakes that must stay clean, vibration limits and sensitive work that cannot take a drip. We plan the roof in small sections, protect intakes with covers and agree on hours with the lab manager. If a test opening finds wet insulation, work stops for photographs and a scope review before the section is expanded.
Water is the other half of a lab roof. Condensate from cooling coils, drips from process cooling and wash-down discharge can reach the surface, and a drain that serves them needs to be kept clear. We trace each line to its outlet, check for staining or ponding at the discharge point and recommend protective measures where water lands on the membrane.
Some leases give the roof to the owner, some share its cost and some push repairs onto the tenant. A tenant on a short term may never have seen the roof history. A roof condition report gives both sides a shared factual basis: a plan, photographs, repair dates and an estimate of remaining life.
When a leak starts, the report helps decide whether it follows a known weak point or a new problem, which in turn helps settle responsibility. Property managers who handle many tenants can use the same report format across buildings, and a company in property management with a mixed portfolio can answer a question about who should pay from the same set of documents.
Capital timing follows the same facts. A short remaining term, a planned sale or a refinance each changes when a replacement should happen, and the roof plan can show the owner what each option costs and who bears it at each stage.
The Raleigh weather service's regional record of hail, tornado and damaging-wind reports and Cary's wet year do not describe a specific Chapel Hill roof, but together they justify a walk before the stormy months. We clear drains, check edge metal and coping, tighten loose fasteners and seal small defects.
After a storm, a second walk compares the roof with the earlier photographs. Impact marks, lifted edges and debris against curbs are documented, and storm damage is separated from age. Where the roof is leaking, a commercial roof leak repair locates the entry and rebuilds the detail, and the interior is checked for moisture that may outlast the repair.
A written checklist goes to the manager after each walk. It lists what was cleared, what was tightened, what was sealed and what remains for the next visit, so the roof's care does not depend on memory.
A light-colored membrane or coating lowers the surface temperature of a roof, and the effect shows most on a building whose cooling equipment works hard in the afternoon. A cool roof installation is a decision made along with insulation, drainage and membrane choice, not in isolation. We describe the effect as a mechanism, not a promised saving.
The scope lists the reflectivity target, the insulation level and the cost drivers. Owners with buildings in Durham or at Research Triangle Park can compare options across properties. North Carolina builds under the state code family, so local requirements are confirmed for each permit before pricing.
Cleaning matters because dirt lowers reflectivity over time. A scheduled wash or a rinse after pollen season keeps the surface working as intended, and the cleaning method must suit the membrane so the surface is not damaged.
Two checks settle it: whether the support still carries load and whether the opening beneath it is sealed. A dead unit on a good curb can wait, while one that rests on bare membrane or leaves an open line should be removed and the roof closed properly. We list each item with a recommendation.
By phasing the work, protecting air intakes and scheduling noisy or dusty tasks for agreed hours. The lab manager tells us which zones are most sensitive. We open the roof in small sections, and each section is dried in before the end of the shift.
Responsibility follows the lease and the cause, and a roofer cannot rule on either. We document where the water entered, the condition of the surrounding roof and any tenant equipment nearby. Both sides can then discuss responsibility with the facts in front of them.
It usually costs far less than the interior damage from a clogged drain or a lifted edge. The walk finds those problems while they are small. We photograph each area, so the owner can see that the roof was in order before the season and compare afterward.
Not by itself. Insulation depends on the building's energy requirements and the existing assembly. A reflective surface over thin or wet insulation delivers little, so we check the existing board before recommending a surface.
