Why do Flat Roofs Leak?
In short the answer is ignorance. The roof pictured to the
right is a brand new foam roof installed by a well known
roofing contractor in the valley. To the untrained eye the
roof really looks good. Even up close it looks good. The
problem with it is that we needed to completely remove this
roof and install
another
brand new roof because the methods used in the installation
pictured actually
caused lots of leaks!
We do not have room here to fully explain this. See the
article in our newsletter for the Spring of 2008 for a
complete explanation. Basically, the reason this home and so many
flat roofed homes have and do perpetually leak is because
the roofing industry in general does
not understand the
Building Envelope.
When roofers foam or roof up over the roof to wall flashings
they actually
trap the water in the walls!
Water does get behind stucco
period!
When it does, it needs a place to exit and drain out onto the
top of the roof. That is what the flashings are for and
when those are roofed over it creates
leaks!

more questions on this topic. |
