Coat a flat Monterrey rooftop with reflective cool-roof paint

Flat concrete rooftops across Monterrey's colonias soak up the day's extreme heat and radiate it straight into the rooms below, keeping homes hot well into the night. A reflective cool-roof coating, rolled on like paint, cuts how much heat the roof absorbs in the first place. This is ground-reach work limited to single-story or safely accessible flat roofs. Standard: WHO heat-health guidance; SDG 7 (Affordable and Clean Energy) Proof: Photo of the finished reflective roof coating Method (WHO heat-health guidance; SDG 7 (Affordable and Clean Energy)): 1. Confirm the host invites the work and check the roof is a single-story, safely accessible flat surface. 2. Sweep the roof clear of loose debris and dust. 3. Roll on the reflective cool-roof coating in even coats per the product instructions. 4. Let the first coat dry before applying the second. 5. Photograph the finished, coated roof and record the application date. Done when: Photo of the finished reflective roof coating

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash. You see which before you claim, never after.

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 60–120 minutes. Method of record: ASHRAE Level 1 energy audit

Bring

• tablet/clipboard
• tape measure
• light meter (lighting scope)
• clamp thermometer (refrigeration scope)
• 12-month utility bills
• camera
• ladder + spotter (high fixtures)

Steps

1. 1. Confirm the address; arrange a staff escort for mechanical/back-of-house.
2. 2. Photograph HVAC, lighting, envelope, and any in-scope systems.
3. 3. Inventory systems: HVAC type + age; lighting fixture count/type/wattage; refrigeration units; envelope condition.
4. 4. Summarize 12 months of utility use (kWh / therms) from the bills.
5. 5. Take the in-scope measurements (light levels, unit temperatures, seal condition).
6. 6. Rank no-cost/low-cost measures, then capital measures, with rough savings logic.
7. 7. Enter inventory, measurements, utility summary, photos, and the ranked measure list; sign.

If it does not match the plan

• Knob-and-tube, ungrounded or overheated wiring, scorched outlets, or a hot electrical panel -> STOP: do not operate the circuit; route to a licensed electrician and restrict use (NEC / fire hazard).
• Gas odor, or a combustion appliance with absent/blocked venting (backdrafting / CO risk) -> STOP: evacuate, ventilate, call the gas utility. The agent escalates, never relights or adjusts gas.
• Any live-electrical/gas hazard -> document, do not touch, flag for a licensed pro.
• Refrigeration unit out of food-safe range -> flag as both energy and food-safety risk.
• Suspected asbestos/lead in materials -> flag and stop.

What counts as done

• System inventory complete for the in-scope equipment
• 12-month utility use summary recorded
• In-scope measurements recorded with units
• Ranked no-cost/low-cost + capital measure list produced

Proof is measured against these, not judged by taste.
