McMillan & Johnston Contracting | Roofing Services in Chandler, AZ 85286

In Chandler, a common culprit for leaks in tile roofs after monsoons is failing underlayment beneath the tiles. The high winds and driving rain can exploit any existing weakness. Our specialty includes detailed tile roof underlayment inspections and repairs. We'll carefully lift the affected tiles, assess and replace the compromised underlayment, and reseal everything properly to restore your roof's integrity against our local weather.

Our comprehensive inspection is the foundation of our honest assessment approach. We conduct a thorough visual examination of your entire roofing system, including shingles or tiles, flashing, vents, gutters, and the underlayment on accessible areas. For flat roofs, we pay close attention to seams, coatings, and potential pooling areas. We then provide a detailed report with photos, explaining any issues we find and presenting all viable repair or replacement options, prioritizing solutions that extend your roof's life.

We offer a full range of services for flat and low-slope roofs common in Arizona. This includes repairing seams and punctures, addressing ponding water issues, and applying protective coatings like acrylic or silicone to reflect sunlight and extend the roof's lifespan. For more extensive damage, we are experts in modified bitumen roof installations and replacements. Our goal is always to provide the most effective and durable solution for your specific flat roof.
