I had a 25 year roof installed after my roof was damaged by hail. The
original roof
had been on about 20 years and was in good shape up to the point the
hail beat it to
death. This new roof is about 9 years old and I see that its curling
(upward) in
various sections on the south face of the roof. The roofers want $5700
to do the
whole roof and $3K to do the curled face about (20' by 20').

Now since there should be another 15 years left on the remaining 3/4s
of the roof and
I feel that the $3K is a rip off what I feel I should do is: to re
shingle over the
20 by 20 area,,, nailing down the curled corners of the original roof
as I shingle my
way up the roof shingling right over the existing roof. At $20 per
bundle I could do
the four square for about $240 bux.

I reason that it's not good practice to shingle over shingles but I
have seen lots
and lots of roofs shingled over shingles and since I'll have to do the
rest of the
roof in about 15 years, these need only last that 15 years. Doing it
this way also
allows me to do the roof at a leisurely pace. (I'm old and heavy)
[yes,,,,fat!]

What do you think? Does the plan hold water? (No pun)

I wouldn't want two layers of shingles, but I'm not the one doing the
work )
Neither do I know the going rate for the work you need......I assume you
have
gotten more than one bid?!! If ventillation is part of the problem, you
will only
add to it by putting on another layer of roofing. If you are able to
tear off the old
stuff, you could certainly do it in stages and "blue tarp" it or get
together some
neighbors to help (or hire a roofer who moonlights). The side of the
roof getting
less sun might last 15 years longer than expected. During a long, tedious
process of getting our condo roof problems resolved, I kept bugging my
husband
and one interested neighbor about the ventillation. They both kept
telling me the
vents were adequate until they got tired of my bitching and decided to
check.
Someone had stuffed fiberglass insul. into the roof vent. Probably to keep
rats out )
