Roanoke on the record
Census QuickFacts puts Roanoke's population estimate on July 1, 2025 (V2025) at 99,111. The same source gives the population counted in the Census on April 1, 2020 as 100,011, and on April 1, 2010 as 97,032.
What NOAA's Roanoke station lists
NOAA's engineering weather data includes a station at Roanoke, at an elevation of 1,175 feet. Its figures, set out together here, are the station's own:
- Design temperatures, Roanoke station: a 1% summer design temperature of 90°F, with a mean coincident wet-bulb temperature of 73°F, and a 99% winter design temperature of 16°F.
- Wet-bulb hours, Roanoke station: in an average year, about 305 hours with the wet-bulb temperature above 73°F and about 1,604 hours above 67°F.
A utility note
According to the Western Virginia Water Authority, it was formed on July 1, 2004, when the water and wastewater operations of the City of Roanoke and Roanoke County consolidated. It now provides water service to over 69,000 customer accounts and wastewater service for more than 60,000 accounts in the City of Roanoke and the Counties of Roanoke, Franklin and Botetourt and the Towns of Boones Mill and Vinton.
Treat the stain as a message
Spots on a ceiling or a closet wall are where a moisture problem has become visible, not where it started. Spores are part of ordinary indoor dust, and they wait on anything they can feed on: drywall facing, wood, carpet backing, stored paper. Growth follows dampness that lasts. That makes the useful question "where is the water coming from?" rather than "what will kill this?"
A remediation job that holds up is built around that question. The source is found and repaired by whoever owns that system, the materials are dried and measured, the growth is removed or cleaned under control, and only then does anyone close the wall.
Tracing moisture room by room
Walk the house with a flashlight and a notepad before you call anyone, and look in places that don't announce a leak:
- The attic. Look at the underside of the roof deck around vents, chimneys and valleys, and at any bath fan duct that ends in the attic instead of outdoors.
- The kitchen. Open the sink cabinet and feel the floor of it. Pull the refrigerator out if it has an ice maker line, and look behind the dishwasher kick plate.
- Bathrooms. Press the floor beside the toilet and the tub. Check grout and caulk at the tub or shower edge, and note whether the exhaust fan clears steam.
- The heating and cooling equipment. Look at the condensate pan and drain line, and at ducts running through any space that isn't conditioned.
- Below grade. In a basement or crawlspace, look for damp masonry, a wet vapor barrier or none at all, and water marks at the base of walls.
- Outside. Watch where gutters and downspouts drop water during a rain, and which way the soil slopes next to the foundation.
Keep assessment and removal apart
Ask whether the person who describes the problem is separate from the company that will remove it. When the same firm writes the scope and does the work, it is deciding how big its own job is. A separate written description, from someone with mold experience you can ask about, gives every bidder the same target and gives you something to measure the finished work against.
What a containment plan should say
A proposal worth signing describes, in writing:
- where the growth is, how far it extends and the moisture source behind it;
- plastic sheeting that seals the work area, with a zippered entry;
- an air machine with a filter holding that area under negative pressure;
- porous material such as drywall, insulation and carpet bagged before it leaves the sealed area;
- how framing and subfloor that stay will be cleaned and dried;
- the moisture target and how readings will be logged;
- how the company will show you the work is done before anything is rebuilt.
Signs that call for a closer look
- a musty odor that comes back soon after cleaning;
- dark spotting along ceiling corners, inside closets or on window trim;
- paint that blisters, or drywall that dents under a thumb;
- swollen baseboards or trim pulling off the wall;
- a ring-shaped stain under a bathroom or an attic air handler;
- beads of water on cold pipes or ducts.
None of these shows how far growth reaches behind a surface. Each one is a reason to find the moisture and have the area opened.
Looking without making it worse
If you lift a carpet edge or open a wall panel, wear gloves, eye protection and a well-fitting disposable respirator, and keep children and pets elsewhere. Don't scrub dry growth or point a fan at it. Questions about health and exposure belong with your doctor.
Questions for every remediation company
- What is the moisture source, and who repairs it before cleanup starts?
- Who wrote the description of the growth, and is that person independent of your crew?
- What state license or registration, if any, covers this work, and what is the number?
- Will your own employees do the work, or a subcontractor?
- Can you send proof of liability coverage and workers' compensation?
- What moisture readings will show the structure is dry, and will I get them in writing?
- What does your final report include?
Insurer, permits and the scope
Call your own insurer early and ask what your policy says about mold and about the water damage behind it, and which records it wants. If the repair means new framing or moved plumbing or wiring, ask the contractor whether the city needs to issue a permit and who will apply for it. Then hand each bidder the same written description and compare prices for that work, not for different ideas of the job. Keep photos, readings, reports and receipts in one folder.
