Overview
NOAA records show Roswell averaging 11.6 inches of rain and 63.2 F annually, meaning it sees infrequent rain but high sensitivity to leaks when storms hit.
Roswell sits in southeastern New Mexico where the climate is dry with large temperature ranges and limited precipitation.
Roswell Code Enforcement enforces city codes that promote health and safety.
This guide highlights local moisture drivers, seasonal risk, and prevention steps. For legal rights and landlord obligations, review the New Mexico mold laws guide.

- Roswell gets only 11.6 inches of rain per year, but each storm tests roof flashings and window seals. Inspect promptly.
- Roof flashing, gutters, and downspout extensions.
- Attic insulation and ventilation near eaves.
- Window frames and sills with condensation.
- HVAC condensate drain lines and drip pans.
- Water heater pans and nearby floor drains.
- Bathroom exhaust fans and vent ducts.
- Under sink plumbing and cabinet bases.

Warning Signs of Mold in Roswell
Watch for these signs that moisture is lingering in Roswell homes and rentals:
- Persistent window condensation in Roswell (annual average 63.2 F) is a common early indicator that indoor humidity is too high.
- Condensation that returns on windows each morning.
- Musty odors in closets or interior rooms.
- Peeling paint near baseboards or window trim.
- Dark spotting near ceiling corners.
- Soft drywall around tubs or showers.

Mold Risk Factors in Roswell
These are the most common moisture drivers for homes and rentals in Roswell:
- Roswell sees just 11.6 inches of rain per year, so plumbing leaks and HVAC condensation create more mold risk than outdoor weather.
- Large temperature swings can create window condensation when indoor humidity is high.
- Low precipitation means indoor moisture from plumbing and cooling systems is often the main driver.
- Cooling systems create condensate that must drain properly.
- Plumbing leaks under sinks and behind tubs can keep wall cavities wet.
- Bathrooms without exhaust ventilation trap moisture in interior rooms.

Roswell Seasonal Risk Calendar
Winter
Cold nights increase window condensation risk.
Spring
Variable precipitation can reveal roof or window leaks.
Summer
Cooling systems work hard at a 63.2 F average, increasing condensate loads. Check drain pans and dehumidify basements.
Fall
Temperature swings return. Recheck seals and indoor humidity.

Roswell Moisture Playbook
Use this short playbook to stay ahead of common moisture problems in Roswell.
After a Leak
Stop the water source, remove wet materials within 24 to 48 hours, and dry the area with airflow.
Monthly Maintenance
Clear condensate lines, inspect under sinks, and log indoor humidity.
Seasonal Tune Up
With only 11.6 inches of yearly precipitation, any storm is significant. Prep window seals and drainage before wet weather.

Mold Prevention in Roswell
Use these priorities to keep indoor humidity low and avoid recurring growth:
- Even 11.6 inches of yearly precipitation can cause problems if window seals and door gaps are not maintained before storms.
- Maintain indoor humidity between 30 and 50 percent.
- Dry wet materials within 24 to 48 hours.
- Vent bathrooms and kitchens outdoors.
- Clear gutters and direct downspouts away from foundations.
- Inspect roof flashing and window seals before storm seasons.
- Service HVAC condensate drains annually.

State Laws and Rights
New Mexico mold law snapshot
New Mexico does not have a mold-specific statute, but habitability rules still apply.
New Mexico courts have held that there is no judicial implied warranty of habitability, but the Legislature enacted the statutory Uniform Owner-Resident Relations Act which creates habitability requirements. Under NMSA Section 47-8-20, landlords must make repairs and do whatever is necessary to put and keep the premises in a safe condition, maintain electrical, plumbing, sanitary, heating, ventilating, and air conditioning systems in good and safe working order, supply running water and hot water at all times, and provide reasonable heat. Mold that affects health and safety would fall under the requirement to keep premises in a safe condition.
