"A roof and its gutters work as a team. Custom-fit seamless aluminum gutters and oversized downspouts move Colorado rain and snowmelt away from your home — protecting the foundation, the siding, and the new roof you just invested in."
Your roof's job is to shed water. Your gutters' job is to carry that water away from your home before it can damage your foundation, siding, landscaping, and walkways. The two work as a system — which is exactly why it makes sense to have the same roofer who knows your home handle both. A great new roof draining into failing, undersized, or leaking gutters is a problem waiting to happen.
Thomsen Roofing installs custom-fit seamless aluminum gutters, formed on-site to the exact length of each run with no seams except at the corners and downspouts. That matters in Colorado: traditional sectional gutters are joined every few feet, and every one of those seams is a spot that eventually leaks, clogs, and separates. Seamless gutters eliminate those weak points, giving you a cleaner look and far fewer leaks over the life of the system. We also install oversized downspouts where they make sense, because the Front Range can dump a lot of water fast — from intense summer downpours to spring snowmelt running off the roof.
Owner Scot Thomsen has been protecting Boulder-area homes since 1985, and gutters are a natural part of doing the whole job right. Whether you're pairing new gutters with a roof replacement or simply replacing tired, leaking gutters on their own, we'll size and install a system that handles Colorado's weather and complements your home.
Custom-formed on-site, sized for Colorado weather, and installed by the roofer who already knows your home.
We form each gutter run to the exact length of your home on-site — no piecing together short sections, so the fit is clean and precise.
Seamless construction eliminates the joints every few feet that plague sectional gutters — the spots that leak, clog, and separate over time.
Where it makes sense, we install larger downspouts that move heavy rain and snowmelt fast — a real advantage in Colorado's intense weather.
Quality aluminum won't rust, holds up to Front Range sun and temperature swings, and comes in a range of colors to match your home.
Properly placed downspouts direct water away from your foundation, preventing the erosion, settling, and basement moisture that poor drainage causes.
Having one trusted contractor handle both roof and gutters means they're sized and installed to work together — no finger-pointing, no mismatched work.
Gutters tend to be out of sight, out of mind — until water is running down your siding or pooling against your foundation. If your gutters are leaking, sagging, or simply can't keep up with a Colorado downpour, they're no longer protecting your home, and the damage they allow is far more expensive than the gutters themselves.
It's worth a look if you're seeing any of these:
When your roof and gutters are installed by two different companies, the seams between their work become your problem. Gutters hung wrong can trap water against the fascia and roof edge; a roof that drains poorly overwhelms gutters that weren't sized for it. When something leaks, each company points at the other.
Thomsen handles the whole system. Because we know your roof — its pitch, its drainage, the volume of water it sheds — we size and install gutters that actually work with it. It's the same hands-on, do-it-right approach Boulder has trusted since 1985, applied to every part of keeping water where it belongs: off your roof, away from your home.
Measured, formed, and installed right — straightforward from your first call to finished gutters.
We evaluate your roofline, drainage needs, and the right gutter and downspout sizing.
An itemized written estimate — color, sizing, downspout placement, and scope.
We form your seamless gutters on-site to the exact lengths your home needs.
We hang the gutters with proper slope and secure, well-placed downspouts.
We clean up, confirm proper drainage, and make sure everything flows correctly.
Sectional gutters are joined every few feet, and every seam is a potential leak, clog, and separation point over time. Seamless gutters are formed on-site as continuous runs with joints only at the corners and downspouts — so there are far fewer places to fail. The result is fewer leaks, less maintenance, and a cleaner look that holds up better through Colorado's weather.
It's often the smart move. If your gutters are aging or leaking, replacing them alongside the roof means everything is sized, installed, and finished to work together as one system — and it's more efficient to do both at once. Having one contractor handle both also means no finger-pointing if there's ever a drainage issue. We're happy to do gutters with a roof replacement or as a standalone job.
Because Colorado weather can move a lot of water in a hurry — intense summer downpours and fast spring snowmelt running off the roof. Larger downspouts drain that volume faster, reducing overflow and the backups that lead to ice and water damage. We assess your roof's drainage and recommend downspout sizing and placement that can actually keep up.
We typically install 5-inch seamless aluminum gutters, which suit most Front Range homes, and we'll recommend larger sizing or additional downspouts where a roof sheds a lot of water. The right size depends on your roof's area, pitch, and how the runoff concentrates — which is exactly the kind of thing we evaluate during your free assessment.
Gutters and downspouts carry roof runoff away from the house. Without them — or with failing ones — water pours straight down along the foundation, where it causes soil erosion, settling, cracks, and basement or crawlspace moisture. Properly placed downspouts that discharge water well away from the house are one of the simplest, most effective ways to protect the structure below.
Seamless aluminum gutters come in a wide range of durable factory-finished colors, so you can match or complement your roof, trim, and siding. During your free estimate we'll go over the options and help you choose a color that looks right on your home and holds its finish through Colorado's sun and seasons.
