Joel Johnson was my rep and helped me navigate the process. They helped me overcome some hurdles with my insurance company. The communication was great and installation was efficient despite the challenges of living in the mountains. Overall was a good experience and glad I went with Joel and Roof Technologies.

Built for Longmont — The Tech Corridor, the Flood-Plain & Two Counties

Longmont is its own market. A tech-corridor city (IBM's long-running Longmont campus, Seagate, Agilent, the DigitalGlobe legacy, GE Johnson's engineering footprint) wrapped around a historic Old Town that dates to the 1870s, with the top-ranked St. Vrain Valley School District, McIntosh Lake and Union Reservoir on its edges, the Boulder County Fairgrounds anchoring the east side, and city limits that cross the line between Boulder County and Weld County. That last detail — split-county governance — is the one that trips up most roofers working here. We run every Longmont project with the right county authority, the right utility interconnection (LPC or Xcel), and detailing specified for flood history and downslope winds.

  • Class 4 impact-rated shingles for the US-287 hail corridor (2018 & 2023 events)
  • Wind-rated detailing for 60-80 mph downslope bora events off the foothills
  • Reinforced flashing & ice-and-water shield for St. Vrain flood-plain parcels
  • Full permit handling on both the Boulder County and Weld County sides
  • LPC (Longmont Power & Communications) and Xcel Energy solar interconnection
  • Free estimates across Longmont, Mead, Frederick, Firestone, Niwot, Hygiene, Lyons & Berthoud

Our Core Values

How We Run Every Longmont Project

The principles behind every roof, solar install, and rebuild in Longmont — from the first permit routing call to the final county inspection.

  • 1

    Transparency

    Written quotes, documented scopes, county-routing confirmation, utility-interconnection paperwork — all handed to you before material ships. No surprises, no upsells.

  • 2

    Technology-Driven Process

    Every Longmont job moves through our proprietary project system, tracking City of Longmont permit status, Boulder or Weld County inspection routing, and LPC or Xcel interconnection milestones.

  • 3

    One Point of Accountability

    One project manager owns every phase — coordinating our in-house crews and vetted trade partners — so Prospect, Old Town, and tech-corridor commercial projects always have one number to call, not a chain of handoffs.

  • 4

    Customer-First Finish

    Every Longmont project ends with a walkthrough, a magnetic nail sweep, and a full documentation packet — Class 4 certificate, manufacturer warranty, and inspection sign-off ready for your insurer.

Why Longmont Homeowners Choose Us

Experience Across Every Corner of Longmont

Longmont isn't one neighborhood type — it's at least four, and a competent roofer has to handle all of them. Old Town Longmont carries housing stock from the 1870s, with Victorian profiles, historic masonry, and interior framing that predates modern sheathing standards. Prospect, Renaissance, and the newer custom-home neighborhoods on the west side are tight new-urbanist or architect-custom builds where the HOA will reject a replacement that doesn't match the original spec down to the drip-edge color.

Meadow View, Southmoor Park, The Fields, and the mid-century ranch corridor are straightforward volume roofs where the margin lives in install quality and warranty paperwork, not exotic materials. And the tech-campus commercial buildings — along Ken Pratt, Pike Road, and the Diagonal — are low-slope TPO, foam, and modified-bitumen work with energy-code implications. We run the same documented process across all four — historic, custom, volume, and commercial — and match the scope to the building, not the other way around.

Longmont Solar Panels & Tesla Solar Roof

Longmont has a split utility picture most Front Range installers don't handle correctly. Longmont Power & Communications (LPC) is a municipal utility — it serves most addresses inside the city directly, with its own interconnection agreement, its own net-metering structure, and its own application workflow. Xcel Energy serves the rest: unincorporated parcels, newer annexations outside the LPC footprint, and most of Mead, Frederick, Firestone, Niwot, Hygiene, Lyons, and Berthoud. We confirm service territory for every address before we file anything.

Across all of it, Longmont's solar economics are strong — 300+ sunny days a year, high residential electricity demand, and Colorado's state-level incentives. We install traditional arrays across every Longmont neighborhood, and we specify the Tesla Solar Roof for Prospect, Renaissance, and the custom-home streets where integrated glass tile is the cleanest path to HOA approval over a bolt-on panel array. Permit, interconnection, and final inspection handled end-to-end.

FAQ

Common Questions From Longmont Homeowners

Yes, and it matters more than most homeowners expect. Longmont city limits cross the Boulder County / Weld County line, and which side your parcel sits on determines which county's building department issues inspections and which assessor's records pull for the permit. The City of Longmont handles most residential re-roof permits directly, but any work that triggers a structural review (deck replacement, rafter repair, solar mount) routes to the correct county. We pull the parcel before we quote, confirm which jurisdiction has authority, and file the permit accordingly — so inspection sign-off isn't held up over a routing error.
It does. The September 2013 flood put the St. Vrain River over its banks through the center of Longmont and wiped out homes along Hover, McIntosh Lake, and the corridor east toward the South Platte. On flood-plain and former-flood-plain parcels, sheathing and framing can still carry moisture history that shortens shingle life and telegraphs through a new roof within a few seasons. We core-check the deck before tear-off, specify reinforced step flashing and ice-and-water shield well up the valleys, and document everything for your carrier — especially important where flood-plain homes still carry separate flood policies with strict repair protocols.
Longmont sits directly east of the foothills gap that channels downslope winds (sometimes called bora winds, distinct from chinook warm-wind events) through the city. Peak events routinely hit 60-80 mph sustained with higher gusts, and they come from the west — exactly the direction Longmont roofs face their ridgelines. Standard 3-tab shingles and builder-grade architectural shingles shed tabs in these events. We specify wind-rated architectural shingles (typically 130 mph or higher ratings), six-nail attachment, and starter-course sealing at rakes and eaves — Longmont-specific detailing, not generic Front Range.
The June 2018 and August 2023 hail events both tracked along the US-287 corridor, concentrating damage on Longmont, Lafayette, Erie, and the southwest Weld County towns. If your roof was in-service during either event and hasn't been replaced since, there's a very good chance it carries compensable damage — whether you noticed it at the time or not. We inspect, document with photos and measurements, and work alongside you through the claims process. Most Colorado carriers are familiar with the 287-corridor hail tracks and expect claims from those dates.
Yes — State Farm, Farmers, USAA, and Allstate all offer Class 4 impact-resistant discounts on Longmont policies, typically 15-30% off the wind/hail portion of your premium when you install a UL 2218 Class 4 rated roof. Given how often Longmont sits under severe hail cores (two major events in five years), the upgrade pays back faster here than in many markets. We provide the Class 4 certificate and installation documentation with every project so you can submit it directly to your carrier for the discount.
It does. Prospect is a master-planned new-urbanist neighborhood with a design code tighter than most Longmont HOAs — approved material lists, a narrow color palette coordinated with the neighborhood's architectural guidelines, and required pre-approval from the ARC before work begins. Traditional architectural asphalt is generally approved in specific colors; some elevations were originally built with metal accents or standing-seam sections that have to be replaced in kind. We prep the Prospect ARC submittal (product data, color chip, scope description) and wait for written approval before we schedule tear-off.
Yes, and this is a detail a lot of Front Range installers get wrong on Longmont jobs. Longmont Power & Communications (LPC) is a municipal utility — it serves most of the city directly, not Xcel Energy. LPC has its own interconnection agreement, its own net-metering rules, and its own application packet, separate from Xcel. However, parts of greater Longmont (particularly outside city limits in unincorporated Boulder or Weld County, and some annexed-in corridors) are on Xcel. We check service territory against the parcel first, then file with the correct utility — LPC for most of Longmont proper, Xcel for the rest.
We serve Longmont and the surrounding corridor on both sides of the county line — Mead, Frederick, Firestone, and Dacono to the east and southeast in Weld County; Niwot, Hygiene, and Lyons to the west and south in Boulder County; and Berthoud to the north. Same documented process, same project manager — whether you're in a Prospect new-urbanist, an Old Town Victorian, a Meadow View ranch, a tech-campus commercial building, or a Mead or Firestone new-build on the Weld County side.
