Gutter Installation in Houston, TX

New gutters catch the water running off your roof and carry it through downspouts away from the foundation, fascia and doorways. In Houston's heavy downpours, the layout matters as much as the gutter itself: enough downspouts, sized and placed to carry the flow, with outlets that send water somewhere it can drain. This Old House's seamless gutter guide (updated October 2026) puts aluminum around $7 per linear foot installed and a typical 200-foot job near $1,984 nationally. These national averages are a yardstick for local quotes, not a Houston price list.

Signs you need new gutters

• Water sheets over the front edge in hard rain, even when the gutter is clean.
• Joints drip, or sections sag and pull away from the house.
• The fascia board behind the gutter is soft, stained or rotting.
• Soil is washing out, or water pools along the foundation or at a door.
• Rust, holes or split seams on older steel gutters.
• Paint is peeling or mildew is streaking on siding below the gutter line.

Some of these are fixable without full replacement. This Old House lists gutter repair at about $180–$560 and full gutter replacement at about $1,000–$3,000 nationally. A contractor should tell you which one your house needs and why.

Seamless versus sectional

Seamless aluminum is a common choice. The installer forms each run on site from a coil, so long walls have no joints except at corners and outlets. Sectional gutters come in pieces joined with connectors, and every joint is a potential leak. Even seamless systems have seams at corners, end caps and downspout outlets, so ask how those are sealed.

This Old House's national installed prices per linear foot:

• Vinyl: about $4.
• Aluminum: about $7. It resists corrosion.
• Galvanized steel: about $9. Stiffer, but it can rust where the coating wears through.
• Copper: about $20, usually chosen for looks.
• Zinc: about $40.

Downspouts do most of the work

A gutter only holds water briefly; the downspouts drain it. This Old House says a system typically needs one downspout per 20–25 feet of gutter. Long runs, valleys that dump water into one corner, and two-story roofs that drain onto a lower roof all need more capacity. Ask the installer:

• how many downspouts they plan, and where;
• whether downspouts are standard or oversized;
• where each one discharges, and whether extensions, splash blocks or a buried drain line carry water away from the slab.

Never point downspouts at a neighbor's yard or into a buried line nobody has checked. Water that pools against a slab foundation is a problem a gutter is supposed to prevent.

How gutters meet the roof

The gutter hangs on the fascia board, just below the roof's drip edge. The drip edge is a metal strip that sends water off the shingles into the gutter instead of behind it. If the drip edge is missing or too short, water runs down the back of the gutter and rots the fascia. A good installer checks:

• that the drip edge overlaps into the gutter;
• that the fascia is sound before hanging anything on it, with rotten boards replaced first;
• that hangers are spaced close enough to carry the weight of a full gutter;
• that the gutter is pitched slightly toward each outlet so water does not stand in it.

If you are planning a new roof, coordinate the two jobs. Roofers often replace drip edge, and new gutters hung before the roof may be damaged or need to be pulled. Our roof replacement page covers the roof-edge details. Low-slope sections may drain through a scupper (an opening in the edge wall) rather than a gutter, and that outlet needs its own detail.

Gutter guards

Guards keep leaves and pine needles out, which helps in neighborhoods with heavy tree cover. This Old House lists average installed prices for major guard brands of roughly $40–$62 per linear foot nationally, much more than the gutter itself. Guards reduce cleaning but do not eliminate it, and some types can make roof-edge repairs harder. Ask how the guard attaches, whether it goes under the shingles, and whether that affects your shingle warranty.

The Texas Department of Insurance lists keeping gutters clean among its roof maintenance tips. Clogged gutters back water up under the roof edge.

What a good gutter quote lists

• material, profile and size, and whether it is seamless;
• total linear feet, number of corners, and number and size of downspouts;
• hanger type and spacing;
• removal and disposal of old gutters;
• fascia or drip edge repair, priced separately;
• downspout extensions or drain connections;
• guards, if any, by product name;
• any written workmanship warranty.

Leave ladder work at roof height to the installer. A fall from a ladder can cause serious injury.

Common questions

How much do new gutters cost in Houston?

Houston-specific gutter pricing isn't published in a survey we could verify. This Old House's October 2026 national figures put seamless aluminum near $7 per linear foot installed, with about $1,984 for a 200-foot system. Ask a local pro to measure your house.

Are seamless gutters worth it?

For most homes, yes. Fewer joints means fewer places to leak, and aluminum does not rust. Corners and outlets still have seams that need sealing.

How many downspouts does my house need?

This Old House suggests one per 20–25 feet of gutter as a typical figure. Valleys and big roof areas that drain to one spot may need more.

Should I replace gutters before or after a new roof?

After, or at the same time with both contractors coordinating. Roofers often replace drip edge, which ties into the gutter. Our Gulf Coast roof care guide covers seasonal upkeep.
