Commercial Roof Installation in Greeley, CO

A new commercial roof is one of the largest investments a building owner makes, and in Northern Colorado it has to survive more than most roofs in the country. Hail, high winds, intense UV, heavy spring snow, and big temperature swings all test the installation, not just the materials. Two buildings can get the same membrane from the same manufacturer and see very different results. One lasts decades. The other starts leaking after its first hail season.

Martinez Roofing Inc installs commercial roofing systems for business owners, property managers, developers, and HOAs in Greeley and throughout Northern Colorado. For more than 26 years, we’ve handled full roof replacements, insurance-funded hail replacements, and new roofs on new construction and additions. Every project is managed by our own team from the first inspection through the final walkthrough.

Commercial Roof Installation Services

Full Roof Replacement

When an existing roof has reached the end of its life, we remove it down to the deck. We inspect the structure, repair or replace any damaged decking, and install a complete new system. A full tear-off exposes problems that would stay hidden under a new layer, and it resets the life of your roof entirely.

Hail Damage Replacement

In Weld County, many commercial roof replacements start with a hailstorm. We document the damage, meet with your adjuster, and review the insurance scope line by line so nothing required for a proper installation gets left out. If your policy includes ordinance or law coverage, it may help pay for upgrades the building code requires during replacement, such as added insulation. Learn more about our storm damage repair services.

New Construction and Additions

For new buildings and additions, we work alongside your general contractor, architect, or project manager. We review plans for drainage, insulation, penetrations, and edge details before materials are ordered, so issues get solved on paper instead of on the roof. We also coordinate our schedule with the other trades to keep the project moving.

Roof Recover

In some cases, a new membrane or coating system can go over a single existing roof layer. That is only an option when the old roof is dry, sound, and allowed under local code. A recover can reduce tear-off and disposal costs, but it is never the right choice over wet insulation. We verify conditions before recommending one.

Commercial Roofing Systems We Install

We recommend a system based on your building’s use, drainage, rooftop equipment, hail exposure, and budget.

• TPO: A reflective, heat-welded single-ply membrane that lowers summer cooling loads. Thicker membranes over a high-density cover board hold up much better to hail.
• EPDM: A synthetic rubber membrane that stays flexible through freezing nights and hot afternoons, and is simple to maintain and repair.
• PVC: A heat-welded membrane that resists grease, chemicals, and fire. It is the preferred choice for restaurants and many industrial buildings.
• Modified bitumen: A multi-ply asphalt-based system that handles foot traffic and service visits well.
• Metal roofing: A long-lasting system with strong hail and wind performance. Our custom metal manufacturing lets us fabricate panels, flashings, and trim to fit your building.
• Asphalt shingles: Impact-rated shingle systems from Owens Corning, GAF, and Malarkey for apartment communities, HOAs, churches, and other steep-slope commercial buildings.

Building a Roof for Northern Colorado Weather

A roof designed for a mild climate won’t last long on the Front Range. We plan every installation around the conditions your roof will actually face.

Hail Resistance

Hail damage on commercial roofs often happens below the surface. Hailstones crush the insulation and bruise the membrane from underneath. We build hail resistance into the assembly with three choices:

• High-density cover boards
• Thicker membranes
• Systems that have been tested for hail performance

These choices add some cost up front, but they can mean the difference between a roof that shrugs off a storm and one that needs a claim.

Wind Uplift

Northern Colorado’s wind puts the most stress on roof edges, corners, and perimeters. We attach insulation and membrane to the manufacturer’s wind requirements, add fastening where the loads are highest, and install new edge metal and coping built to stay put.

UV Exposure and Temperature Swings

At our elevation, sunlight is more intense, and afternoon temperatures can climb far above the overnight low. Materials expand and contract every day. We choose membranes, flashings, and sealants rated for those conditions, and we detail seams and transitions to handle constant movement.

Snow Load and Drainage

Spring storms can drop heavy, wet snow on low-slope roofs. Snowmelt that can’t drain refreezes at night and puts extra weight on the structure. We use tapered insulation and proper drain placement to move water off the roof, and we check that drains, scuppers, and gutters are sized for the building.

What Goes Into a Properly Installed Commercial Roof

Every commercial roof is an assembly of layers. When one bid comes in far below the others, a layer is usually missing or being done cheaply.

• Roof deck: We inspect and repair the steel, wood, or concrete deck before anything goes on top.
• Vapor retarder: It keeps interior moisture out of the insulation in high-humidity buildings, such as restaurants, pools, and laundries.
• Insulation and tapered insulation: Rigid insulation controls energy costs. Tapered insulation creates slope toward drains to stop ponding.
• Cover board: A dense board over the insulation that improves hail and foot traffic resistance and gives the membrane a solid surface.
• Membrane or metal panels: The weatherproof layer, attached by adhesive, fasteners, heat welding, or a combination, depending on the system.
• Flashings and penetrations: Walls, curbs, pipes, vents, and drains are where most leaks start. Each one is flashed to the manufacturer’s specifications.
• Edge metal and coping: The perimeter is the first thing wind attacks. New edge metal, fabricated to fit, keeps the whole system in place.

Our Commercial Roof Installation Process

1. Inspection and Measurements

We measure the roof, document its condition, check drainage, note all rooftop equipment and penetrations, and look for trapped moisture and hail damage. On replacements, we also check the interior for leak history and deck problems.

2. Written Estimate and System Recommendation

You receive an itemized written estimate showing:

• The system and each layer of the assembly
• Insulation thickness
• Flashing details
• Warranty options

If more than one system would work, we lay out the differences in cost, lifespan, and hail performance so you can decide. On insurance projects, we compare our scope against the adjuster’s estimate and flag anything missing.

3. Permits and Scheduling

We handle the required permits with your local building department. We then schedule around your business hours, your tenants, and the forecast. Deliveries, dumpster placement, and equipment lifts are planned ahead of time and confirmed with you.

4. Site Protection

Before work begins, we set up safety perimeters, protect entrances and landscaping, and cover interior areas below the work zone when needed. If rooftop units need to be disconnected or raised, we coordinate with your mechanical contractor.

5. Tear-Off and Deck Repair

We remove the old roof in sections that can be sealed the same day, so the building is never left open overnight. During hail season, we plan each day’s work to be closed up before afternoon storms typically roll in. If we find damaged decking, we send you photos before replacing it.

6. Installation

Our crew installs the full assembly: insulation, cover board, membrane or metal panels, flashings, and edge metal. Seams and details are checked throughout the day, not just at the end.

7. Final Walkthrough and Cleanup

We walk the finished roof with you or your property manager, review the details, and clean the site completely, including magnetic sweeps for nails and fasteners. You’ll receive before and after photos for your records and your insurance file.

Keeping Your Business Running During Installation

A new roof shouldn’t mean closing your doors. On every commercial project, we:

• Keep entrances, sidewalks, and parking areas open and clearly marked
• Schedule the loudest work around your hours whenever possible
• Give you one point of contact who answers the phone and returns calls
• Secure the roof at the end of every workday
• Clean the site daily
• Help you prepare notices for tenants, residents, or staff

Commercial Roof Installation FAQs

How long does a commercial roof installation take?

It depends on roof size, the number of existing layers, the amount of rooftop equipment, and the weather. Smaller buildings can often be finished in a few days. Large or complex roofs may take several weeks. Your estimate includes a projected timeline, and we keep you updated if storms affect the schedule.

Will insurance pay for a new commercial roof after hail?

If your roof has covered hail damage, your policy may pay for repair or replacement, minus your deductible. Coverage depends on your policy terms, the extent of the damage, and your insurer’s decision. We document the damage thoroughly, meet with your adjuster, and help make sure the approved scope covers what a proper installation requires.

What is the most hail-resistant commercial roof?

Metal roofing and single-ply membranes installed over a high-density cover board both perform well against hail. Membrane thickness and the strength of the layers underneath matter as much as the membrane itself. We’ll recommend an assembly based on your building and budget, and we’ll explain how each option holds up to hail.

Do I need to tear off my old roof?

Not always. A new system can sometimes go over one existing layer if that roof is dry, sound, and allowed under local code. If there are already multiple layers, or if the insulation is wet, a full tear-off is required. Covering wet materials traps moisture and shortens the life of the new roof.

Can you install a commercial roof in the winter?

Often, yes. Northern Colorado gets plenty of dry, sunny winter days that work well for roofing. Some adhesives and materials have temperature limits, so we choose products suited to cold weather and schedule around storms. If waiting a few weeks would produce a better result, we’ll tell you.

What warranty comes with a new commercial roof?

A new commercial roof typically includes a manufacturer warranty on the materials and a workmanship warranty from the contractor. Depending on the system and our certification with that manufacturer, some warranties cover the full roofing assembly. We explain your coverage options in writing before work begins.
