Who does everyone use for gutters on your house?

I never put them on mine because they cost an assload. Just put some flagstone where the gulleys dump off the roof.

Most builders of non starter homes in Houston put them in the front and the back only, depending on the config of the roof. I think they're mostly there to reduce damage to landscaping and pitting of ground soil. You can also identify heavy runoff areas and dump river rock there to prevent erosion, etc.

I do have one friend that because of roof config, desperately needs them to transfer water away from the side of his house that gets very little sun, because it's a swamp when it rains.

American Gutter and Awning in Lafayette.

Veteran owned and a great guy. Was about $7/ft and $100/downspout. I did front and my back patio and it was around $1600 if I remember right. Guy was done in just a couple of hours.

For many homes roof runoff is the largest source of water to the lot. If it does not drain quickly away from the house, you need gutters and possibly buried drains in the wet areas. A new house may have great drainage that gets bad after a few decades due to settling, foundation plantings, trees, and things your neighbors do. I had gutters installed on wet sides by Premiere South and drains installed by Samson Services. Both are BTR area.
