Flat Roofing in Nogales, Arizona

The flat roofs are common on the commercial buildings and the mid-century homes in Nogales. The flat surface handles the snow differently than the pitched roofs, and the monsoon rain needs the proper drainage. Flat roofing in Nogales means the materials and the methods built for the border highlands — the UV, the ponding water, and the heat.

Signs Your Nogales Flat Roof Needs Service

• Ponding water after a storm — the drainage is not working
• Blisters or bubbles on the membrane — the heat has trapped the moisture
• Cracked or alligatored surface — the UV has dried out the material
• Leaks at the seams and the flashings — the thermal cycling has pulled the seals apart
• Granules in the downspouts — the modified bitumen is shedding the surface

Why Nogales Flat Roofs Need the Right Materials

The border sun at 3,800 feet is the first challenge. The flat roofs absorb the sun all day and the surface temperatures exceed 160 degrees. The TPO and the white membranes reflect the heat and keep the building cooler.

The monsoon rain is the second challenge. The heavy rain pools on the flat surface and the ponding water finds the weak seams. The proper slope and the drainage are critical.

How We Do Flat Roofing in Nogales

1. Inspect the roof and the structure — check the deck, the drains, and the existing membrane
2. Prepare the surface — clean, repair, and prime the substrate
3. Install the membrane — the TPO, the modified bitumen, or the coating
4. Flash the penetrations — the HVAC units, the vents, and the curbs
5. Test the drainage — the water flows to the drains and the ponding is gone

Preventing Problems on Flat Roofs in Nogales

• Inspect the roof twice a year — spring and fall, before and after the monsoon
• Clear the drains and the scuppers — the debris blocks the water flow
• Check the flashings at the HVAC units — the thermal cycling loosens the seals
• Apply a reflective coating when the membrane ages — the UV protection extends the life

The flat roof in Nogales is an investment in the building. The white TPO membrane reflects the border sun and cuts the cooling costs. The right maintenance doubles the life of the roof.
