What Homeowners Say

Is It Time to Install New Gutters?

DeMarko Gutters builds long-lasting gutter systems that help homeowners prevent water from damaging their properties. We serve Renton, Washington. Instead of using the same gutter installation method for all our clients, we evaluate each individual home. Proper planning helps to avoid mistakes when installing gutters. We evaluate how water flows off the roof and looks at where water can accumulate. From there we look at the areas of the property where more protection is needed, and based on that, we decide on the size of gutters and where and how we will install the downspouts. Every roof has a specific size and is measured to each roofline to ensure the gutters are installed to look clean and finished. We can install gutters to completely surround a house or just to address a specific section where we have identified a problem caused by roof runoff pooling resulting in water damage or soil erosion. We have a range of aluminum gutter systems and we help homeowners install them for the first time or replace old systems.

Gutter Services

Searching for rain gutter replacement near me? DeMarko Gutters installs, repairs, and replaces gutter systems for homeowners and businesses throughout Renton, WA. Every job starts with the same question: how does water actually move across this roof? Roof size, pitch, valleys, and landscaping all shape how a gutter system should be laid out, so we design each installation around the property instead of forcing a one-size-fits-all setup.

Gutter Installation

Seamless Gutters

Seamless gutters are formed in long, continuous sections instead of being pieced together from smaller parts. Fewer seams mean fewer places for water to leak and a cleaner line along the roof. We measure and fit each system to your home for a low-maintenance, durable result.

K-Style Gutters

K-style gutters are a common choice in Renton because their flat back sits neatly against the fascia and their molded front profile blends in with the exterior. They also hold more water than most other styles — useful during the Pacific Northwest’s heavier rain. We size the gutters and downspouts to match your roof’s drainage needs.

Aluminum Gutters

Aluminum is our go-to material: lightweight, durable, and rust-resistant. It can be formed into seamless sections and comes in a range of colors, giving you years of reliable drainage without the gutters standing out.

Custom Gutter Solutions

Not every roofline is a simple rectangle. Multiple rooflines, valleys, additions, and awkward corners all affect where downspouts should go. We map out where water naturally collects and design the layout around it — sometimes that means gutters around the entire home, sometimes it’s just fixing runoff over an entrance or driveway.

Gutter Repair

Not every problem calls for a full rain gutter replacement. Often it’s one section, connection, or downspout causing the issue. We diagnose the source before recommending a fix.

• Leak repair — Leaks often develop at joints, corners, end caps, or damaged sections. We find where water is escaping and repair it before it damages siding, landscaping, or your foundation.
• Sagging or loose gutters — Loose hangers let gutters pull away from the fascia or sag, creating low spots where water pools instead of draining. We re-secure and realign sections when possible.
• Re-pitching — Gutters need a slight slope to carry water to the downspouts. If they’ve shifted or were installed level, we can restore the correct pitch without full replacement.
• Downspout repair — Gutters and downspouts work as one system. We repair damaged connections, elbows, and downspouts to keep water flowing all the way to the discharge point.

Gutter Guards

Leaves, seeds, and debris don’t belong in your gutters. Guards reduce buildup while still letting water flow — no system is fully maintenance-free, but the right one cuts down cleaning significantly.

• Leaf protection systems — Block larger debris like leaves and twigs while draining water freely; especially useful for hard-to-reach roof sections.
• Micro-mesh guards — Finer filtration that keeps out smaller debris — pine needles, seeds, insects — while still allowing water through.
• Debris protection matched to your property — The right guard depends on the trees and debris around your home, so we recommend based on your actual conditions, not a one-size-fits-all product.

Downspouts & Drainage

Gutters collect water; downspouts decide where it goes — and that matters just as much.

• Downspout installation — Placement is based on roof area, water volume, gutter length, and available discharge locations, so you get enough drainage without excess downspouts on the exterior.
• Downspout replacement — Crushed, disconnected, or poorly placed downspouts can undermine an otherwise good gutter system. If the gutters are fine, replacing just the downspout may be all you need.
• Downspout extensions — Carry water farther from your foundation instead of dumping it right beside the house.
• Water diversion solutions — For trouble spots like a washed-out flower bed or a valley overloading one section of gutter, we design a fix for that specific problem.

Gutter Replacement

At some point, repairing an old system stops making sense — corrosion, repeated leaks, poor original installation, or gutters too small for the roof are all signs it’s time for rain gutter replacement in Renton, WA. We evaluate your existing setup before recommending full replacement.

• Old gutter removal — We carefully remove existing gutters and downspouts and check the fascia for issues before installing anything new.
• Full gutter replacement — Rather than copying a system that wasn’t working, we reassess sizing, pitch, downspout locations, and discharge points from scratch.
• Damaged section replacement — Storm or impact damage doesn’t always mean replacing everything. We can replace just the damaged section and tie it into the existing system.
• Seamless aluminum upgrades — Fewer joints, cleaner look, and a solid mix of durability and value for homeowners upgrading from an older sectional system.

Questions About Gutters

Are gutters horizontal or vertical?

Gutters should have a slightly competitive edge leading to the downspout to allow for the sufficient downward drainage of rainwater. Although gutters should be level, when viewed from the ground, they should not appear to be obviously crooked. Gutters should have enough of a pitch to allow water to drain and not be flat enough to pool water or so upright that they cause one end of the gutter to fill up and spill over.

What’s the gutter install process?

We measure the length of the roofline to determine the required length of gutters. Once we decide on the length, we attach the gutters to the roofline using hangers or other similar hardware. We install gutters with a small slope to allow the water to flow in the correct direction toward the downspouts. We place the downspouts so that water exits the downspouts and drains away from the side of the house. With several types of gutters, long runs are fabricated off site, so there is only a slight seam at the ends and we can avoid having to join and leak sections together.

Can metal roofs have gutters?

Absolutely, gutters can be installed vertically on metal roofs. Special consideration should be given to the placement of gutters on a metal roof to control the flow of water from a downpour.

How should gutters be positioned on houses?

Gutters are installed on the roof edge and capture water run-off in this preferred location. Considering downspouts, we determine the placement where roof water drainage will most likely cause water damage to the property. We focus on roof valleys in particular, as well as large roof sections, as these can direct a lot of water into a small area.

How are correct gutter systems identified?

Whilst correctly installed gutter systems are level and appear to be flush to the roof line, properly installed gutters do in fact have a slight fall toward the downspout. A correctly installed gutter is installed to the roof line without sagging, and then sealed to the fascia board. Water flows into gutters and, without overflow or leaks, directs to the downspouts and discharges the water away from the house.

Do angled fascia boards create problems with gutter installation?

Angled fascia boards do not interfere with gutter installation. Additional hardware may be required to maintain the desired fall of the gutter on a sloped roof.

Can gutters be installed without a fascia board?

Gutters can be installed without a traditional fascia board. Additional hardware such as roof hangers or different roof mounts can be used as long as there is another means for mounting the gutter on the roof. The method used is dependant on the construction of the roof and eaves.

Can downspouts drain to pipes below ground?

Yes, provided they are connected together. This is popular if a surface connection can’t be used, or to protect a property’s appearance. An underground drainage pipe should be aligned properly to funnel water away from the property’s foundation.

Should damaged gutters be replaced or repaired?

This depends on the extent of the damage. A leak, a gap, a damaged corner, or even a slight separation and misalignment of gutters can most likely be repaired. However, if gutters have pulled away from a home, are bent, leaky, and beyond their useful life, then these gutters should be replaced. In order to make this determination, we do evaluate the entirety of the gutters.
