Longmont Exterior Remodeling — Siding, Roofing, Windows, Decks & Outdoor Living
Longmont is not just a pin on our service-area map. Our kids go to school here and play sports here, and we volunteer in this community. We have served Longmont since 2001 from just up the road — a short drive, not an hour-plus haul from the metro.
Northern Lights Exteriors has served Longmont homes since 2001. We are based nearby — not an out-of-area crew dispatched from the Denver metro. We handle siding, roofing, replacement windows, decks, patio covers and outdoor living in-house — one contract, one permit path, one crew schedule, one warranty conversation. Because we are close by rather than dispatching from the metro, we can be on site quickly when a storm opens a roof, and we are still around in year five when a warranty question comes up.

Planning a larger exterior project? Ask for a bundled estimate for windows + siding, roofing + gutters, or a full exterior renovation.
Set in Boulder County with views of the Front Range, Longmont is known for its mix of historic neighborhoods, established communities, and growing new developments. But like much of Colorado, it also faces hailstorms, high winds, UV exposure, and winter freeze-thaw cycles. Northern Lights Exteriors has more than 25 years of experience delivering durable, high-performance siding, roofing, windows, decks, painting, and storm restoration solutions built for Longmont’s climate and local building codes.
Longmont Windows, Siding, Roofing & Full Exterior Remodeling
Many Longmont homeowners start with searches like windows and siding, siding and windows, windows and siding near me, window and siding contractors, siding and window replacement, or exterior contractors near me. In many cases, they are not looking for two separate crews. They are looking for one experienced exterior contractor who can coordinate the whole project.
Northern Lights Exteriors specializes in multi-trade exterior remodeling for Longmont homes. Instead of juggling several companies, homeowners can work with one team for design, scheduling, installation sequencing, warranty coordination, and final closeout.
- Windows and siding replacement for older Longmont homes where trim, flashing, weather barrier, and insulation details need to work together.
- Roofing and gutters coordinated with siding, paint, or storm-restoration scopes.
- Siding, windows, doors, and composite decks for curb-appeal and lifestyle upgrades.
- Full exterior remodels that combine siding, windows, roofing, gutters, decks, trim, paint, and storm-repair items.
Why homeowners like a one-source remodel approach: better scheduling, better pricing, cleaner design continuity, and better warranty coordination. Trusted since 2001, Northern Lights Exteriors helps Longmont homeowners upgrade the full exterior without the confusion of managing multiple trades on their own.

Why Replace Siding and Windows at the Same Time?
Homeowners searching for windows and siding near me are often asking the right question. Replacing siding and windows together can improve the way your exterior works as a complete system. When the cladding is open, installers can reset trim details, improve flashing, air sealing, and weather barriers, and make sure the finished lines around the windows look clean and intentional.
- Better integration of flashing, trim, and weather barriers.
- Cleaner exterior design and more consistent sightlines.
- More efficient labor sequencing than doing each trade separately.
- Better opportunity to coordinate paint, fascia, gutters, and other finish details.
- One contractor accountable for the whole scope instead of several disconnected installers.
If you are comparing window and siding contractors, the biggest difference is not just price. It is how well the company can coordinate the entire exterior envelope. That is where a multi-trade exterior remodeling contractor can create better long-term results for the homeowner.

Why a Nearby Contractor Matters More Than It Sounds
Plenty of good exterior companies will drive to Longmont from the Denver metro or the south suburbs.
Distance is not a character flaw — but it does change what you can realistically expect, and it
is worth understanding before you sign anything.
- Storm response is measured in minutes, not drive time.
When hail or wind opens a roof, the clock matters. A crew a short drive away can tarp and document
the same day. A company dispatching from the metro is triaging a queue that spans the whole
Front Range before it gets to you. - Our installation warranty runs five years — someone has to still be there to honor it.
The real test of a contractor is whether anyone answers when a flashing detail needs attention two
or three winters later. We are still working in Longmont every week, and coming back is a short drive. - Longmont permits and HOA review are their own process.
We pull permits here constantly. Familiarity with the local submittal path and the design-review
expectations in Longmont neighborhoods removes weeks of back-and-forth. - After a hail event, local capacity is the whole game.
Big storms pull crews in from out of the area, and quality gets uneven fast. Our crews were
working in Longmont before the storm and will still be here after it. - Reputation here is face-to-face. We see our Longmont customers at our kids’
games and around town. That is a different kind of accountability than a company that can
quietly stop taking calls in this ZIP code.
Longmont is where our family spends its weeks. Our children go to school here and play sports here,
and we volunteer in this community. Since 2001 we have built our reputation the slow way — one
roof, one siding job, one set of windows at a time, for neighbors who know where to find us.

Outdoor Living in Longmont — Patio Covers, Pergolas, Porches & Sunrooms
Exterior remodeling in Longmont does not stop at the walls and roof. A large share of what we build
is the part of the house people actually spend summer evenings in. As patio builders in
Longmont, CO and outdoor living contractors, we design and build these as
structural work — footings, beam sizing, snow load, drainage and flashing — not as bolt-on
carpentry.
| What we build | Best for | Longmont considerations |
|---|---|---|
| Patio covers | Shade and rain protection over an existing patio | Attached covers must be flashed into the siding properly or they become a leak path; engineered for Front Range snow load |
| Pergolas | Defined outdoor room with partial shade | Freestanding or attached; wind uplift matters more here than most homeowners expect |
| Covered porches | Front-entry curb appeal and shelter | Roofline has to read as original to the house, not an addition; usually permitted |
| Three-season sunrooms | Extending usable season into spring and fall | Ventilation and drainage detailing decide whether it stays comfortable and dry |
| Composite & hardwood decks | Low-maintenance outdoor floor space | See our Longmont deck builders page for materials and pricing |
Because we also side and roof the house, the tie-in is handled by one team. That matters: most
failures on patio covers and porches are not the structure — they are the seam where the new
roof meets existing siding.
How to Read an Exterior Warranty (Before You Sign One)
Warranties are one of the easiest places in this industry to be impressed by the wrong thing.
It helps to know that almost every exterior project carries two separate warranties,
and they are backed by completely different people.
| Type | Covers | Backed by |
|---|---|---|
| Manufacturer warranty | The product itself — the siding, shingles or window units | The manufacturer. Commonly 20–50 years, and genuinely durable because the company is large and long-established. |
| Installation warranty | How it was installed — flashing, fastening, weather barrier, sealing | The contractor, and only the contractor. It is worth exactly what that company’s continued existence is worth. |
That second row is where most real problems live. The overwhelming majority of exterior failures
are not defective product — they are water finding a path through a detail that was installed
wrong. So the installation warranty is the one that actually protects you.
Why “lifetime installation warranty” deserves a follow-up question
A lifetime installation warranty is a promise about the contractor’s
lifetime, not yours. If a company has been in business eight or twelve years, a lifetime promise is
a forecast about a track record that does not exist yet. It is not necessarily dishonest — but
it is unverifiable, and it costs nothing to print.
Worth asking any contractor, including us:
- How many years have you been in business under this name and this ownership?
- Is the installation warranty written into the contract, or described verbally?
- What specifically is excluded, and what voids it?
- Who performs the warranty repair — your own crew, or a subcontractor?
- Is it transferable if I sell the house?
Where we stand: Northern Lights Exteriors has been in business since 2001 —
about 25 years. We offer a 5-year installation warranty on our workmanship, alongside
the manufacturer warranties on the products themselves, which typically run 20 to 50 years. We would
rather put a number on it that we have the history to stand behind than print a word that sounds
bigger and means less.
