Commercial Roofing Contractors for the Front Range
Northern Lights Exteriors repairs, replaces and installs commercial roofs for HOAs, apartment and condo communities, retail, office, light industrial, church and civic buildings across Colorado’s Front Range. We work on flat, low-slope and steep-slope roofs in TPO, EPDM, PVC, metal and asphalt, and we restore eligible metal and flat roofs with silicone and acrylic coatings.
The short answer: one project manager from first inspection to closeout, a line-item proposal that compares repair, restoration and replacement side by side, phasing built around occupied buildings, and an on-demand client portal where your board, owners or managers can see schedules, photos, inspections, warranty documents and payments without waiting on a call back.
Commercial Roofing Services
- Commercial Roof Repair: Leak investigation and repairs at seams, flashings, penetrations, drains and edge metal.

- Commercial Roof Installation: TPO, EPDM, PVC, metal and asphalt systems on new and existing buildings.
- Roof Coatings: Silicone and acrylic restoration for metal and flat roofs to extend life and improve reflectivity.
- Multifamily & HOA Roofing: Phased schedules, resident notices, access coordination and inspections.
- Roof Inspections: an in-person inspection on the roof and a written condition report with photos, so you know where the roof stands before you budget.
- Storm Restoration: Hail and wind claims, code upgrades and closeout documentation.
Commercial Roof Repair & Leak Response
Most commercial roof leaks start at a detail, not in the middle of the membrane. Freeze-thaw cycles, strong UV at altitude and hail all work on the same weak points, so that is where we look first. An active leak is treated as an emergency: call the office and it goes to the front of the inspection schedule.
- Seams and laps: open or failed seams on TPO, PVC and EPDM, re-welded or re-sealed to manufacturer details.
- Flashings and penetrations: pipes, curbs, rooftop units, skylights and hatches, often the source of leaks that seem to move around.
- Drains, scuppers and gutters: clogged or undersized drainage and ponding water that shortens roof life.
- Edge metal and coping: loose or lifted perimeter metal after wind events, a common starting point for blow-offs.
- Hail and impact damage: punctured or bruised membrane, cracked cover board and dented metal panels.
- Metal roof leaks: backed-out fasteners, failed sealant at laps and panel ends, and rusted trim.
Every repair comes with photos before and after, a short written summary and a note on what else we saw while we were up there, so you can plan instead of react. If repairs are no longer the smart money, we will tell you, and show you why.
Commercial Roof Replacement: Repair, Restore or Replace?
The right answer depends on what is under the membrane. A moisture survey and core samples show whether insulation is wet, how many roofs are already on the building and what the deck looks like. Then we price the options side by side.
| Option | Best when | What it involves |
|---|---|---|
| Repair | The roof is sound and leaks trace to specific details. | Targeted work at seams, flashings, penetrations or drains, documented with photos. |
| Restore (coating) | A metal or flat roof is dry and well attached but aging. | Cleaning, seam and penetration repairs, then a silicone or acrylic coating system. |
| Re-cover | Code allows another roof layer and the existing insulation is dry. | New cover board and membrane installed over the existing roof. |
| Full replacement | Insulation is wet, leaks keep returning, or the roof is at the end of its life. | Tear-off to the deck, new insulation and tapered drainage, new membrane, flashings and edge metal. |
Your proposal lists each option with its scope, price and expected service life, so a board or owner can compare long-term cost rather than just the lowest number.
Commercial Roof Installation: TPO, EPDM, PVC, Metal & Coatings
- TPO: reflective single-ply membrane with heat-welded seams, a common choice for energy savings.
- EPDM: durable rubber membrane, proven on large low-slope roofs. Black or white, fully adhered or mechanically attached.
- PVC: chemical- and grease-resistant for restaurants and industrial buildings.
- Metal roofing: standing seam and exposed-fastener systems for commercial, agricultural and mixed-use buildings.
- Asphalt shingles: steep-slope roofs on multifamily, clubhouse and community buildings.
- Fluid-applied coatings: silicone and acrylic systems for eligible metal and flat roofs.
Need more than a roof? We can put roofing alongside windows, doors, siding and gutters on the same proposal, with one project manager across every trade.
Hail and Commercial Roofs on the Front Range
Hail is the biggest single threat to commercial roofs here. On low-slope roofs the damage is often invisible from the ground: bruised or punctured membrane, crushed insulation, cracked cover board, and dented metal edge, panels and rooftop unit fins.
- After a storm: we inspect and document every roof section, not just the obvious spots, so the claim reflects the whole roof.
- On a new roof: we can specify hail-resistant assemblies, such as a high-density cover board under the membrane and thicker membranes, and we will show you what each upgrade costs.
- With your carrier: we meet adjusters on site and make sure code-required items are part of the scope. Learn more about commercial storm damage claims.
Working on Occupied Buildings
Most of our commercial roofs are on buildings that stay open: apartments and condos, HOA communities, stores, offices and churches. The plan is built around the people inside.
- Assessment: an in-person inspection on the roof, photos, core samples, infrared imaging as needed, and a code review.
- Phasing plan: building-by-building or section-by-section order, crane and delivery days, parking and staging areas.
- Notices: resident and tenant notices before work starts and schedule updates as it moves.
- Daily site safety: protected entrances, egress and accessible routes kept open, and odor-sensitive adhesives where air intakes are close.
- Coordination: rooftop unit disconnects and resets coordinated with your mechanical contractor.
- Closeout: final inspection, punch list, warranty registration and a photo package.
Proposals Built for Boards & Property Managers
An HOA board or ownership group has to approve the work, often months before it starts. Our proposals are written so they can be presented as-is.
- A line-item scope with alternates (repair, restore, re-cover, replace), so the board compares options in one document.
- Phasing that can follow your reserve study or budget year, building by building.
- Photos and inspection findings attached, so members who were not on the roof can see what was found.
- One contact for the board, the manager and residents. More on how we work with HOAs and property managers.
Your Whole Project in One Place: Our Client Portal
Commercial roofing involves a lot of people who all want the same answers. Our custom-built, on-demand client portal keeps them in one place:
- Your signed contract and itemized scope, so you can easily get a refresh on what was agreed, on your own, any time.
- Permit status and inspection results.
- Material delivery and install schedules.
- Before, production and final photos.
- Payments, per trade.
- Warranty documents after closeout.
Portal access is set up for each client once a project begins, and a manager can share it with board members and owners.
Commercial Roof Warranties, Explained
- Manufacturer material warranty: covers defects in the membrane, panels or coating itself.
- Manufacturer system warranty: available on qualifying projects; the manufacturer reviews the installation and covers the roof system as a whole.
- 5-year installation warranty: our warranty on how the roof was installed, in writing.
Your proposal states exactly which warranties apply to your roof before you sign. At closeout they are registered and stored in your client portal, so nobody has to dig for paperwork years later.
Spec Options to Hit Your Goals
- Efficiency: reflective membranes, tapered insulation and edge securement for wind ratings.
- Durability: walk pads, traffic routes and penetration details that stop recurring leaks.
- Compliance: edge metal to ANSI/SPRI ES-1, fire ratings, and guard requirements near roof edges.
- Operations: odor-sensitive adhesives, low-noise methods and storm-season staging.

Commercial Roofing FAQs
How do I choose the best commercial roofing company near me?
Start with a few friendly questions: are they licensed, will they pull the permit, and who is your one point of contact from proposal to closeout? Northern Lights Exteriors has served Colorado since 2001 as a Class C general contractor (license #C120350). Every project has one project manager, a line-item proposal with options, and an on-demand client portal so boards, owners and managers can check schedules, photos, inspections and payments on their own, any time.
Do you handle commercial roof repair, or only replacement?
Both. We repair leaks at seams, flashings, penetrations, drains, scuppers and edge metal on flat, low-slope and metal roofs, and we document every repair with photos. When repairs stop making financial sense, we lay out restoration and replacement options side by side so you can compare cost and remaining service life.
What should I do if my commercial roof is leaking right now?
Call our office at (303) 776-5263. Protect what is below the leak, photograph the ceiling and the roof area if it is safe to reach, and note when it happens (during rain, snowmelt or wind-driven storms). We treat an active leak as an emergency and schedule it for an in-person inspection first, and the inspection report tells you whether a repair, a coating or a replacement is the right next step.
When should a commercial roof be replaced instead of repaired?
Replacement usually makes sense when wet insulation is widespread, the membrane has shrunk or split across large areas, leaks keep returning in new places, or the roof has reached the end of its expected service life. A moisture survey and core samples show what is actually under the membrane, so the decision is based on evidence rather than guesswork.
Which flat roof system is best for my building?
TPO, EPDM and PVC each fit different needs: rooftop traffic, grease or chemical exposure, reflectivity goals, local code and budget. TPO is reflective with heat-welded seams, EPDM is a proven rubber membrane for large low-slope roofs, and PVC resists chemicals for restaurants and industrial uses. We spec the system to your building and goals.
Are roof coatings a good alternative to replacement?
On metal and flat roofs, yes, when the membrane and insulation are sound. Silicone and acrylic coatings can extend service life and improve reflectivity. We test adhesion, repair seams and penetrations first, and confirm which warranty applies before you commit.
Can you work on occupied HOA, apartment and retail buildings?
Yes. We phase work by building or roof section, send resident and tenant notices, keep entrances, egress and accessible routes open, plan crane and material deliveries around operations, and coordinate inspections so the property keeps running.
Do you help with hail and wind insurance claims on commercial roofs?
Yes. We document damage across the whole roof, meet adjusters on site, estimate in the same platforms carriers use, and make sure code-required items are included. What an insurer pays is the insurer’s decision; our job is complete, accurate documentation.
What warranties come with a commercial roof?
Usually up to three layers: the manufacturer’s material warranty, a manufacturer system warranty where the project qualifies, and our 5-year installation warranty. Your proposal spells out which ones apply, and the warranty documents are registered at closeout and kept in your client portal.
Do you work with property managers across multiple properties?
Yes. Managers can keep every property’s proposals, schedules, photos, inspections and payments organized in the client portal, with one project manager coordinating across sites.
