My house is a 1966 ranch, and every September I stand in the yard and watch the wind pull at the gutter seams like it’s checking for a way in. Then the first rain comes and tells me exactly where I was wrong. As of mid-September 2026, half the neighborhood group is trading names of gutter people because somebody’s downspout dumped water straight into a foundation crack last winter, and nobody wants to repeat that.
Hard water and dry heat don’t touch gutters directly, but they wreck the fascia and paint that hold them, and thirty years in this house has taught me the failure is never the gutter — it’s the slope, the hangers, or a downspout aimed at nothing useful.
How I picked these: I read Google reviews, checked Thumbtack and BuildZoom where they existed, and looked at the state contractor board record where the file already had one. The floor was fifty-plus Google reviews, a rating of 4.5 or better, and something recent — not five-year-old praise. All three work in or near Moreno Valley. Standard disclosure, and I mean it: no one on this list paid to be here, and I have no business relationship with any of them.
1. ThEnd Seamless Rain Gutters
This is the outfit people mention when their roofline isn’t a straight line. One homeowner had a flat, curved roof that needed multiple custom cuts, and the crew apparently handled it without drama. Google has them at a full 5 out of 5 across 78 reviews, and Thumbtack has their C-43 sheet metal license verified as of last year. They’re a small crew — two employees on record — so ask flat out how many days out they are before a storm, and get the linear footage and hanger spacing in writing, not just a number scribbled on a card.
2. Sutton Roofing and Solar
What sold me on this one is a review fragment that actually explains drainage: water directed into the gutter instead of behind it, which is the whole game if you want to keep your fascia board from rotting out. They’re roofers first, gutters second, with 64 Google reviews at 5 out of 5 and forty-seven permitted projects on record through BuildZoom, plus bond and workers’ comp listed there too. Photograph your fascia before you call, especially any peeling paint or soft wood, because that’s the add-on they’ll likely flag and price separately.
3. Steep Flat Roofing
Biggest review base on this list — 102 on Google, still sitting at 5 out of 5, with a BBB A+ to match. One homeowner had seamless gutters run around the entire house as part of a full reroof and said the crew stayed communicative the whole time, which counts for something when a job stretches past a day. They’re licensed C-39 roofing, two years in business under that name. Their public materials talk roofs, not gutters specifically, so ask them straight whether gutter work is bundled with a roofing job or something they do on its own before you build a timeline around them…
