Hello All,

I have a flat roof which collects a tremendous of water after it rains.
Does anyone have any ideas on how to fix it. Is it possible to convert a
flat roof to
an inclined one? Is it costly? Any ideas and suggestions would be greatly
appreciated.

Aflat room should be pitched slightly so that water will run off one
end. If the support joists have sagged that may be preventing adequate
runoff.

It is certainly possible in many cases to replace the roof, such as on
older mobile homes but the cost is fairly high

I would try to get someone to inspect the roof and give you a report on
repairing or replacing it.

It just occured to me that there were some flat roofs which were
effectively a tank that drained through one or more large downpipes. If
thats the case check for any blockage of the drains

Our condo assn. got estimates for correcting such a problem. The bid
mentioned something called "Firestone APP-Cool" - described it as a
tapered foam composite that adds slope to a flat roof and insulates it.
Has to be covered, and I am not familiar with the process so went
looking at Firestone's website for info. I don't find a product by the
name we were given, but here is a link for something similar:

Looks good on paper )

Why people design buildings with flat roofs is beyond me. It isn't
rocket science to know that flat + water = leaks. Cost of construction
I suppose couild be a reason but then when you factor in the cost of
the high tech covering (that will leak) plus repair thereof several
times where is the savings? We recently spent a couple million to
covert the HS flat roof to a peak roof to correct the problem. Also
spent over a million re-doing the flat roof on the court house and
jail. Interesting that the jail roof still leaks in the same spots.

I haven't bought many houses in my 70 years but when I was shopping I
wouldn't look at anything that had a flat roof on any portion thereof.

Certainly it can be done. The cost depends largely on if you take off the old
roof, or just build up a new one. When I moved into my home many years ago, the
living room (which was originally a wide porch) had a shallow pitch which
leaked many times over the years. It was a shed roof addition onto the hip
roofed main portion of the house. The room had the pitch raised two times by
previous owners!

I found that the very first roof was nearly flat, a hot tar roof with just
enough pitch to drain. Sometime long ago another roof was built over it using
2x4 sleepers, with the high end raised a bit more. Finally, someone added a
third, similar roof structure, pitched a bit higher yet. But even this last
roof was less than a 2/12 pitch. The closed in areas between the various roofs
were dry rotted from lack of ventilation and small leaks. Some of the rafters
were so black and crumbled from rot they looked like they had been through a
fire.

I ended up tearing the entire roof structure off the whole house, not just the
living room addition and building a proper 5/12 pitch gable roof. Here is a
link to the before and (almost) after. I am also adding a two story addition to
the rear.

Does the roof currently leak?
Any home repair can be done and this certianly is a common one the
question is do you reall NEED to do it. there are several ways you can
help the existing roof drain better but I will wait for your reply
first.

Anecdotal evidence from the apartment where I used to live:

After my complaining for three years about the leaks in the kitchen
ceiling, right on the two ceiling lamps, the owner gave up on going up
to the roof and trying to patch anywhere he thought might be the cause
and called the roofers. Some days after the new roof was in place we
had some snow and as soon as it warmed up water rushed down in the
wall space between the kitchen and the bathroom. Luckily for me this
time it went straight to the two apartments below, who were flooded,
and I only got to see it through a hole under the kitchen sink.

In short: Neither the owners, nor the roofers had thought on looking
at the rather old vent pipes, and one of the pipes was rusted through
which had been the cause of the leaks. All they would have needed to
do was break the wall of my bathroom and replace the pipe, instead of
paying 8.000 dollars can. for the roof. It was solved by
'temporarily' plugging the vent -it was never repaired, now the
building is being turned into luxury condominiums with the help of
some paint.

The roof does leak above the kitchen. There is a one big pool of water
above that location.
I have no idea on how to trace the leak with out tearing the whole ceiling
above the kitchen.

PS: Thanks everyone for the great info.

Is it possible to convert a flat roof to an inclined one?

Definitely possible - I've seen this done on everything from single
family homes to condo complexes.

The conversion needs to be done by a contractor who understands the
issues involved - for example on a flat roofed structure the roof and
supporting walls are designed to withstand a mostly vertical load, once
a pitched roof is added there will likely be additional lateral
(outwards) loads present, so the modifications need to be designed and
everything tied together to withstand the new loads.

You will also need to consider how to modify roof penetrations such as
chimneys and vent - strange things happen if you don' think it all
through grin:

In the case of a larger or complicated structure, the conversion might
have to be designed by a engineer.

Another issue is height - in my area many newer flat-roofed
structures were designed to *just* comply with zoning requirements, in
such cases if you want to add additional height a variance may be
required.

So the place to start is the local building department, to see what
would be involved in permitting such a conversion.

One thing i've seen is using spray foam and some coating (perhaps
rubber sheeting) to regrade the roof to drain to some corner where the
water is drained. You also get the benefit of lots of insulation---
(R6-8 per inch) on your roof.

Can't give you a link off hand... but i'm sure google can help there.

good luck!
