Valley Retrofit

Many installations used asphalt paper as a material for valleys.

The only problem with this is, the paper usually wore out at about 8-10 years into the life of the roof.  This leaves major problems.

With the typical lifespan of a roof in the 20 year range, serious problems arise about 10 years into your roof.  Metal valleys can be installed with no damage to existing roof, thereby maximizing the lifespan of your present roof.  Be careful, this is a hard selling point by commissioned salespersons to push a complete new roof installation on you.  Metal valley installs start at $17/foot + HST.
