The house is a wrap around house with a center courtyard like this:
On three sides are gabled tiled roof, therefore half the water will flow into the direction of the courtyard, the top of the courtyard is enclosed in a screen, therefore in between there is a gutter. It is not a normal gutter but one that has a asphalt surface (like those of a flat roof) and in some spots it feels "spongy" when I walked on it, indicating moisture beneath it. Like this:
Due to this reason, the gutter does not have a smooth grade and hence when it rains it does not flow quickly to the drain. I think I need to fix this gutter, but in talking to several gutter companies they told me they do not service this type of gutters, they only install new aluminum gutters. I asked them who I should call, they don't know. Now is this a gutter problem or a roofing problem?
Now, on the front side the roof is not gabled. It is flat. There is a section connecting the two sides and below it looks like this:
Above however is asphalt roof like this:
and it has an overhanging section extending out to cover the car when parked:
This flat section has no gutter. So it drains at the edges, worse, when the other gutters at the bottom of the gabled roof are not draining quick enough, the water backs up into this flat section, and pours down the below like a bucket.
The courtyard is covered with bricks and have three drains on each side, except the front area where the problem is. So water ponds up and gets inside the sliding glass door and the floor gets wet...a big mess.
Now I am wondering if this is a grading problem of the courtyard, a lack of gutter in the flat section of the roof, a grading problem in the existing gutter, or a clogging problem of the courtyard drain inlets.
What kind of professional do I need to look at all these issues all together, and fix it? Is it a roofer or I need an engineer? Any other advise would be appreciated.
Thanks and sorry for the long lengthy post.
