Commercial Gutter Installation in Houston, TX
Silverheels Construction installs and repairs commercial gutters across the Houston area for property and facility managers — oversized high-capacity and box gutters, scuppers, downspouts, and roof drainage sized for the water a commercial roof actually sheds. Residential gutter sizing fails on a commercial roof, which is where most of these problems start. Free estimates.

A commercial roof sheds far more water than a house, and Houston rain comes hard and fast — so a commercial building needs gutters and drainage sized for that volume, not scaled-up residential parts. When they're undersized or failing, water overflows, backs up, and gets into the wall and foundation. We install and repair commercial gutters and roof drainage across the Houston area: high-capacity and box gutters, scuppers, and downspouts.
Why residential sizing fails on a commercial roof
This is the root of most commercial gutter problems. A commercial roof has a much larger drainage area and is often lower-sloped, so it delivers far more water to the edge, faster, than a house does — and Houston's rainfall intensity is among the highest in the country. Standard five- and six-inch residential gutters and downspouts simply can't carry it; they overflow, the water sheets over the edge, and it erodes landscaping and gets into the building.
Commercial drainage has to be sized to the actual roof area and local rainfall — high-capacity and box gutters, larger downspouts, and more of them. Sizing is the whole point, and it's what a scaled-up residential approach gets wrong. For homes, that's our gutter installation page.
Oversized and box gutters
High-capacity gutters use larger profiles — seven- and eight-inch and up — to carry the volume a commercial roof produces. Box gutters go further: large rectangular gutters, often built into the roof edge or behind a parapet, that hold and move far more water than a standard K-style gutter.
We install oversized and box gutters, fabricated and sized to the building and its roof area, so the water the roof sheds actually gets carried away instead of overwhelming an undersized gutter on the first hard rain.
Scuppers and internal drainage
Many flat and parapet commercial roofs drain through scuppers — openings through the parapet wall — into conductor heads or collector boxes and down through downspouts, or through internal roof drains. These are common failure points: they clog with debris, corrode, and leak at the wall penetration.
We install and repair scuppers, conductor heads, and the collector-box-to-downspout path, and seal the wall penetrations where they leak. We also address overflow scuppers — the code-required backup that lets water escape when the primary drains clog — because a blocked primary with no working overflow is how water ponds deep enough to threaten the roof.
Downspouts and getting water away
Downspouts have to be sized to the gutters feeding them — an oversized gutter into an undersized downspout just backs up — and mounted securely, since commercial downspouts get hit and pulled at ground level. Most important, they have to discharge where the water actually leaves the building, not dump it right at the foundation.
We repair damaged and detached downspouts, upsize them to match the drainage, and correct the discharge so water is carried away from the foundation. It's the same principle as a house, at commercial scale and volume — commercial downspout repair that keeps water from undermining the building.
Warehouse and large-building gutters
Long warehouse and industrial roof edges bring their own challenges: very long gutter runs that have to account for thermal expansion, and enormous water volumes coming off a big low-slope roof. Undersized or poorly detailed gutters on a building like this fail fast and dump water along the whole wall line.
We install and repair gutters and drainage on warehouse and large commercial buildings, sized and detailed for the length of the run and the volume it has to carry, so a long roof edge drains cleanly instead of overflowing down the wall.
Repair, cleaning, and maintenance
Commercial gutter repair covers leaks at seams and scuppers, sagging and detached runs, and corroded sections that no longer hold water. And cleaning is not optional on a commercial roof: gutters, scuppers, and drains clog with debris and back water onto the roof, causing ponding and leaks — so scheduled cleaning, especially before storm season, protects the roof itself.
We repair and clean commercial gutters, scuppers, and drains on a schedule, which pairs with our broader commercial facility maintenance and our commercial roofing work. What drives cost is linear footage, box versus standard profile, the number of scuppers and internal drains, height and access, and material — drivers, not a price.
Frequently asked questions
Why do our gutters overflow even right after cleaning?
Usually because they're sized for a house, not a commercial roof. A commercial roof sheds far more water, so standard gutters and downspouts overflow no matter how clean they are. The fix is high-capacity or box gutters sized to the actual roof area and rainfall.
What are box gutters?
Large rectangular gutters, often built into the roof edge or behind a parapet, that carry far more water than a standard K-style gutter. They're used where a commercial roof's volume demands more capacity than a conventional profile can provide.
Do you repair scuppers and roof drains?
Yes. Scuppers, conductor heads, collector boxes, and the downspout path, plus the wall penetrations where they leak — and overflow scuppers, the backup that lets water escape when the primary drains clog.
Can you clean our gutters and drains on a schedule?
Yes. Scheduled cleaning of gutters, scuppers, and drains — important before storm season, since clogs back water onto the roof and cause ponding and leaks. It protects the roof as much as the gutters.
Do you install gutters on warehouses and large buildings?
Yes. Long-run gutters and drainage on warehouse and large commercial roofs, sized and detailed for the length of the run and the volume, accounting for thermal expansion so a long edge drains cleanly.
Where should the water be directed?
Away from the building. We size downspouts to the gutters and correct the discharge so water is carried clear of the foundation instead of pooling against it, where it gets into the wall and slab.
