A well-specified skylight does three things at once for a Northern Colorado home or building. It brings daylight into vaulted ceilings, kitchens, baths, and interior rooms side windows cannot reach. Operable units vent heat and moisture from kitchens, baths, and sunrooms. And modern Low-E coated glass cuts solar heat gain in summer while reducing infrared heat loss in winter, which matters on the Front Range with its high UV exposure and 60-degree daily temperature swings.
Hail resilience matters here too: the right tempered and laminated layup keeps a skylight intact through Front Range hail seasons. And when a skylight starts to leak, the cause is often not the glass at all; flashing or sealant failure accounts for most "leaking skylight" calls. Residential and low-rise commercial buildings both benefit from a diagnostic-first approach so the fix matches the actual problem.
Moffat installs and services four configurations, each ordered to the diagnosed spec and inspected on receipt.
Glass-only replacement fits when the frame is sound and only the pane has cracked or the IGU has failed (see our insulated glass unit replacement page). Full-unit replacement fits when the frame, gasket, or flashing has degraded.
A hail-resilient skylight layup pairs a tempered outer pane (which absorbs impact) with a laminated inner pane (two glass plies bonded around a polyvinyl butyral interlayer that holds shards in place if a strike penetrates). It is the spec we recommend for exposed Front Range and foothills roofs.
Low-E (low-emissivity) coatings reduce solar heat gain in summer and infrared heat loss in winter; placement on surface 2 or 3 of an insulated unit tunes the seasonal tradeoff. Most modern skylights use an insulated unit; older skylights may be single-pane, and the diagnostic confirms which.
Safety glazing is code-required at sloped overhead locations, so tempered or laminated layups are verified before the factory order ships. Frame condition (aluminum, composite, wood-clad) and gasket fit are checked against the existing manufacturer so the replacement fits the first time.
On the residential side, the most common scopes are skylight installation in new builds and retrofits (vaulted ceilings, kitchens, baths, sunrooms, stairwells), cracked or hail-damaged glass replacement when the frame is sound, leaking-skylight diagnostic and replacement (often the leak is flashing or sealant, not glass), and foggy or failed-seal unit replacement where the perimeter seal has gone (see our insulated glass unit replacement page). Loveland foothills retrofits and Fort Collins luxury homes both see hail-exposure spec calls regularly.
On the commercial side, we install and replace skylights in low-rise buildings up to four stories: offices, retail, hospitality, and mixed-use. We don't pitch high-rise or atrium curtain wall above four stories, and whole-roof replacement is a roofer's scope, not ours.
A Moffat technician confirms whether the issue is glass, flashing, sealant, or condensation; checks frame and gasket; measures the unit; and documents the spec. If the diagnostic points to flashing or roof rather than glass, we recommend a roofer handoff honestly.
Skylight glass and full units are factory-ordered to the diagnosed spec (layup, Low-E coating, safety glazing, brand fit). Lead time runs 5 to 10 business days from approved measurement, for every installer regardless of who orders. A century of Northern Colorado glass work is why we know what to inspect on receipt.
Moffat technicians install, never subcontracted. Roof-access safety, weather check, flashing inspection, and finish protection through completion.
We verify the perimeter seal, confirm no daylight at edges, water-test if conditions allow, and register the warranty. If anything needs adjusting in the first year, the same Moffat team that built it comes back to make it right.
Since 1921, Moffat has worked custom glass across Northern Colorado, and a century of installs and repairs in Larimer and Weld County means we've seen every kind of skylight failure, including the leaks that turn out to be flashing rather than glass. Front Range hail shapes every layup call we make. The technician who diagnoses your skylight is from the same in-house team that installs it; Moffat technicians, never subcontracted. Three locations across the region: Evans HQ, Loveland, Fort Collins.
We're upfront about skylight lead times because the factory order is the same 5 to 10 business days for every installer; what we control is diagnostic accuracy and install quality. The membership stack supports that posture: BBB Northern Colorado A+ accredited, NGA member, plus the Shower Door Professionals Co-op and our Greeley and Evans Chamber memberships. Commercial scope is capped at four stories.
Most skylight leaks come from failed flashing or degraded sealant around the curb, not the glass itself. Common causes include compromised step or counter-flashing where the skylight meets the roof, sealant degradation from years of UV and thermal cycling, a failed IGU perimeter seal that creates fog between panes and is often misread as a leak, interior condensation from high indoor humidity (not a leak at all), and ice damming on Front Range homes that backs water up under the flashing. Each has a different fix. An on-site diagnostic confirms the cause. Schedule a diagnostic visit.
Skylight glass and full units are factory-ordered to spec, so lead time runs 5 to 10 business days from approved measurement, for every installer. Moffat doesn't fabricate skylight units in-house; we diagnose, order to spec (layup, Low-E coating, safety glazing, brand fit), inspect at receipt, then schedule install. Larger commercial orders may run slightly longer. Schedule a diagnostic visit to start your skylight order.
Yes, when specified with a tempered outer pane and laminated inner pane, skylights stand up well to Front Range hail. Tempered glass absorbs impact; laminated glass holds shards in place if a strike penetrates. This layup is the hail-resilience spec we recommend for Northern Colorado homes, particularly in exposed foothills and plains-edge locations. We confirm the right layup at the on-site diagnostic.
Skylight replacement is diagnostic-priced because cost varies by size, skylight type, layup, glass-only versus full-unit replacement, and roof-access conditions. A small fixed-skylight glass swap is a different scope from a large venting-unit replacement with a hail-resilient layup. We confirm the scope at the on-site diagnostic, then quote against the factory order plus install labor. Request a quote for a precise estimate.
Cracked skylight glass is usually replaced, not repaired, because structural integrity and safety glazing cannot be restored to a cracked pane. If the frame and flashing are sound, glass-only replacement is the right call. If the frame is degraded or the flashing has failed, a full-unit replacement (sometimes coordinated with a roofer) is the honest answer. The diagnostic confirms which. Schedule a diagnostic visit to confirm the scope.
Restore the daylight, weather-tightness, and hail resilience of your Northern Colorado home or building with a precise skylight repair or installation specified at an on-site diagnostic visit. Since 1921, Moffat has worked custom glass across Larimer and Weld County, and our diagnostic-first process means we confirm what your skylight actually needs before anything is ordered. Residential and low-rise commercial up to four stories, cracked-glass swaps, hail-damaged unit replacements, and code-required safety-glazed sloped applications are all in scope.

I do not hesitate to recommend Moffat Glass
"We needed our patio screen door replaced. Moffat answered the phone (something that 3 other businesses did not do), scheduled someone to come measure the same day, manufactured our non-standard sized door and installed it within a week. We have yet to hear from the other businesses we contacted who told us they would 'get right back' to us. The quality of customer service was very good. Everyone was friendly, professional, and expressed appreciation for our business. I do not hesitate to recommend Moffat Glass. They have been in Greeley for a long time and I can see why they have lasted."
I will absolutely be using Moffat again and I highly recommend them!
"I'm very thankful to have worked with Moffat glass. I needed a large piece of glass for my hotel with special cuts and Moffat nailed it perfectly!

I will absolutely be using Moffat again and I highly recommend them!"
