Metal roof repair in Phoenix

Most Valley cities have one or two dominant eras of construction. Phoenix has all of them at once, and the roofs show it.

In the historic districts inside the core, Willo, Encanto Palmcroft, Coronado and F.Q. Story, the houses are bungalows and period revival from the twenties through the forties. The original roofs are not metal. What is metal is everything that got added afterwards: patio covers, carports and enclosed Arizona rooms, bolted onto the back of a house that was finished decades before anyone thought about them. Almost every leak we chase in those neighbourhoods is at the junction between the addition and the original wall, because that junction was made by somebody working out how to attach a new roof to an old house, often without flashing it into the wall properly.

Move out to the mid century ring through Sunnyslope, Maryvale and the edges of Arcadia and the pattern changes. Low slope and flat roofs, metal window awnings, attached carports, and a great deal of R panel over patio additions. This is also where the rooftop equipment problem concentrates: package air conditioning units and evaporative coolers sitting directly on metal, with condensate and bleed water running across the panels every day of the summer.

North of the 101 through Desert Ridge, and over the mountain in Ahwatukee, it is post 2000 tract. Tile on the house, metal on the ramada and the RV cover, and increasingly solar mounting feet punched through both.

One thing holds across all three. Phoenix has the longest, hottest summer of any of these cities, and thermal cycling on a long panel run is what walks fasteners out of the purlin. Whatever era of roof you own here, the screws are working loose faster than they would anywhere else in the Valley.
