Fascia Damage From Metal Flashing
The fascia board, isn't only
suffering from deteriorating metal flashing, this roof should have been
designed a little better. Most of the water damage, is from large
amounts of water, draining off of the roof, on a regular basis.
This section of the building could actually be out of level and this
would force most of the water on the roof to drain to this corner.
If you look closely in the upper left-hand corner, you will notice the
metal flashing and the wood fascia board is darker than the other areas
in the picture. Why do you think it's darker? It looks like black mold,
this area could be shaded for longer periods during the day, while the
other areas are receiving direct sunlight. The direct sunlight will dry
the moist areas faster than the areas located in the shade.
This damage wouldn't be hard to fix, and it should be fixed as soon as
possible. If moisture is accumulating on the roofing material and
draining off this corner, on a daily basis. There's a good chance that
there's termites tearing up the wood framing, wood siding and even the
wood fascia board.
Most architects are familiar with roofing problems like this and try to
avoid them, when designing homes or other buildings. This is something
that you might find on a building, that was built before the 1960s.
Home Repair Tip: The roof edge metal will need to be removed and
replaced. The only way that this will be able to be done, will be to
remove some of the roofing and replace it. This repair is going to be
expensive, but should be done as soon as possible.
The longer you leave the wood to rot, the bigger the problem you will
have later with mold, mildew and possibly termites. Don't forget that
termites love moist wood.
