Home › Projects › Gutter Guard Installation in Tacoma
High Point Gutter replaced 254 linear feet of gutter on a waterfront Tacoma home with oversized 6-inch K-style aluminum and covered every foot of it with 6-inch DoublePro. The house is a multi-level design whose roof planes meet at different elevations, so five compound corners had to be cut on site to carry water between sections. The job also included 175 feet of downspouts, 254 feet of drip edge the home did not previously have, and eight adapters tying downspouts into the property’s drain tile.

The situation
The assessment was October 1, 2025. This is a large multi-level home on the water, with a low-slope roof over the main living areas, a separate garage structure, and sections that step down across the site. The original gutters were still on the house and the roof had moss developing in the shaded areas.
What High Point found
Three things shaped the quote.
Water volume. This roof sheds a lot of water into a limited number of outlets. The scope flags one downspout in particular: the front middle downspout drains two areas of gutter, and High Point wrote into the quote that if a 2×3-inch downspout proved insufficient there, the crew would come back and upgrade that specific run to a larger 3×4-inch downspout.
Roof planes at different heights. Where two gutter sections at different elevations have to connect, a standard corner will not do it. Five corners on this house needed a compound angle so the gutter could keep sloping while it turned.
No starter metal. As on many homes of this era, there was no proper drip edge under the roof edge, so water could wick behind the gutter line rather than dropping into it.
What we recommended and why
High Point recommended stepping the system up to 6-inch K-style rather than replacing like for like. Six-inch gutter carries a meaningfully larger volume than the 5-inch profile used on most homes, and this roof’s drainage pattern is what justified it. The 175 feet of 2×3-inch downspouts were then sized and routed to move that water off the building.
For the covers, High Point installed 6-inch DoublePro across all 254 feet. DoublePro is a continuous hanger with a built-in cover, which means it is not a screen laid on top of a finished gutter. It goes on as the hanging system itself, so the cover and the gutter are installed as one assembly. Alu-Rex backs the product with a clog-free performance warranty.
The downspouts were not simply dropped to grade. Eight flex caps were used to step 2×3-inch downspouts down to the 4-inch drain tile already on the property, three custom offsets were fabricated on site to keep runs flush to the wall, and two downspouts were brought together into a single tie-in.
The moss on the shaded sections
The quote included a moss treatment, and it is specific about where. The crew was directed to do a stiff broom removal in the few places along the roof edges where moss had accumulated, and to look around the chimney, where extra water volume and shade had encouraged growth. The treatment itself is a white powdered zinc sulfate monohydrate formula.
How the project was completed
Installation started November 12 and the job completed November 19, 2025. The old system came down, 254 feet of drip edge metal went in under the roof edge, and the new 6-inch gutter was formed on site in seamless lengths. The five compound corners were cut and sealed in place, the DoublePro hanger and cover went on across the full run, and the downspouts, offsets, tie-in, and drain tile adapters finished the water path.
Project cost range
This project fell in the $10,000 to $16,600 range. That covered 254 feet of 6-inch gutter, 254 feet of 6-inch DoublePro covers, 175 feet of downspouts with offsets and a tie-in, five compound corners, 254 feet of drip edge, eight drain tile adapters, counter flashing, and a moss treatment.
Three things put this at the upper end for a residential gutter project. The footage is large. Stepping up from 5-inch to 6-inch raises both the gutter and the cover cost per foot. And the corners and downspout routing on a multi-level house take significantly more fabrication time than a simple rectangular roofline. This range reflects the scope of this completed project and is not a current quote.
What homeowners with similar homes should know
If your home has roof sections at different heights, ask how the corners will be handled. Compound corners are cut to a custom angle so the gutter can keep its slope through the turn. They take longer and they should appear as their own line on a quote, as they did here.
Sizing up to 6-inch is a drainage decision, not an upgrade for its own sake. On this home it was recommended because of how much water the roof sends to a small number of outlets. A quote that recommends 6-inch should be able to tell you which runs drive that.
Note how the quote handled uncertainty. Rather than guessing, it stated that if the front middle downspout could not keep up with the volume from two gutter areas, High Point would return and upgrade that run to 3×4-inch. That is the right way to price an unknown: name it, and say what happens if it turns out to matter.
Related questions
How much do gutter guards cost in Tacoma, WA?
On this project the covers were part of a full 6-inch replacement that fell in the $10,000 to $16,600 range, with 254 feet of DoublePro accounting for roughly a quarter of the total. Cover cost scales with footage and gutter size, so a smaller home with 5-inch gutter lands far below this. This range reflects this completed project and is not a current quote.
What is the difference between DoublePro and a screen-style gutter guard?
DoublePro is a continuous hanger with the cover built into it, so it is installed as the gutter’s hanging system rather than added on top of a finished gutter. That is why it goes on with a new gutter installation, as it did here across all 254 feet. Retrofit covers are a separate product category for gutters that are staying in place.
When do you need 6-inch gutters instead of 5-inch?
Six-inch gutter handles greater volumes of water and debris than the 5-inch profile. It is worth considering when a large roof area drains into relatively few outlets, which is what High Point found on this home. The decision should come from how the roof actually sheds water, not from the size of the house alone.
Can downspouts be tied into existing drain tile?
Yes. On this project eight flex cap adapters stepped the 2×3-inch downspouts down to the 4-inch drain tile already in the ground, and one pair of downspouts was combined into a single tie-in before discharging.
How long did this project take?
