Red tin roof house

Red tin roof house

March–a challenging time to perform work on a metal roof with waterbased materials.  Nighttime temperatures may be too cold and rain appears from nowhere.  A waterbased coating may freeze off the roof surface or, in the case of rain, wash away.

On this project in Pennsauken, NJ, we used a winter formulation as a substitute for the base coat.  The winter coating material is more expensive, stronger and difficult to apply.  But for a contractor, like me, we can work on a 32 degree day.

Note the different color of the roof on the upper left side.  Prep work had revealed a series of unexpected breaks in the tin.  Our primer dripped into the attic area.  With the owner’s approval, we applied the fully reinforced approach just on this weak area.  The photo below illustrates the repair.

All that remains is a top coat of the traditional red acrylic….to be applied on a warm, sunny spring day
