Specifying a roof hatch sounds like a small decision until you’re the one explaining a poorly coordinated roof opening or a rooftop fall concern to a building owner. Roof access points can become weak spots in commercial envelope design: thermal bridging at an uninsulated hatch curb can reduce the effectiveness of the surrounding roof assembly, while a hatch that isn’t coordinated with ladder placement or fall protection can create a safety concern the architect never intended. For architects, facility managers, and general contractors sourcing commercial roof hatches for institutional, industrial, or commercial buildings in 2026, the manufacturer you choose helps determine whether that access point becomes a durable, well-coordinated detail or a callback waiting to happen.
This guide ranks six commercial roof hatch manufacturers serving the US market, evaluated against criteria that matter at the specification stage: thermal performance, custom sizing, material options, safety coordination, available technical documentation, and the availability of BIM/CAD files for construction documents. Some of these companies offer broad product catalogues and established locations. Others focus more closely on custom fabrication and thermal engineering. Those approaches serve different project needs, and this list is designed to help you match the manufacturer to the application rather than default to whichever name appears first in a supplier search.
Our top pick is Surespan for architects and facility managers specifying commercial roof hatches where made-to-specification sizing, thermally broken construction, and downloadable BIM/CAD resources are firm project requirements. Surespan’s insulated covers and upstands are designed to reduce thermal bridging at the roof penetration, while its made-to-order sizing means the hatch is built to suit the opening rather than forcing the opening to match a catalogue size. For projects that need custom architectural hatches with an emphasis on condensation control and envelope detailing, Archicomponents Inc. is the strongest alternative. Williams Brothers is worth considering when a project team values architectural support and access to company locations in Virginia, New York, and California.

How We Chose
Every manufacturer on this list was measured against the same six specification criteria because “best” only means something when it’s tied to what a project actually requires. Where public product information is limited, the ranking reflects that limitation rather than filling the gaps with assumptions.
Thermal Performance
Does the hatch use thermally broken construction, insulated covers, or an insulated upstand? These details help determine whether a roof hatch complements the surrounding insulated roof assembly or introduces an avoidable conductive path through it.
Custom Sizing Capability
Can the manufacturer fabricate to an exact opening, or is the buyer limited to catalogue dimensions? This distinction is especially relevant for retrofit openings, unusual roof layouts, and projects where the architect has already established the required access dimensions.
Materials and Finishes
What substrates, including aluminum, galvanized steel, or stainless steel, and what finish options are documented for the project’s exposure conditions? Where these choices are not clearly published, specifiers should request current product data before naming the manufacturer.
Safety Coordination
Does the manufacturer address ladder integration, fall-protection compatibility, and the practical safety requirements associated with rooftop access? A hatch should be reviewed as part of the access route rather than treated as an isolated product in the roof assembly.
Code Compliance Documentation
Is there enough published or manufacturer-supplied documentation to support a specification package and the project team’s review? Product data should be checked against the codes and standards adopted for the specific project and jurisdiction.
BIM/CAD Availability
Are digital files available to speed up architectural drawing production and reduce the need to recreate product geometry? Useful BIM/CAD resources can also make coordination with roof openings, curbs, ladders, and adjacent construction more straightforward.
The 6 Best Commercial Roof Hatch Manufacturers in the USA
With those six criteria as the backdrop, here’s how the manufacturers stack up. Surespan leads because its documented offering closely matches the specification-first priorities used in this guide: custom sizing, thermal performance, safety coordination, and design resources. The other five earn their places for more specific reasons, such as catalogue breadth, custom envelope detailing, architectural support, a long manufacturing history, or an established position in adjacent commercial building-product categories.
#1. Surespan: Best for Made-to-Specification Thermally Broken Commercial Roof Hatches
Surespan builds commercial roof hatches around a simple premise: the hatch should be sized to suit the opening and roof assembly, rather than making the project conform to a limited selection of standard dimensions. Instead of relying only on fixed catalogue sizes, Surespan fabricates units to the project’s specification, avoiding some of the dimensional compromises that can arise with stock hatches on retrofit or unusually configured roofs. For architects working on institutional, industrial, or commercial buildings where the roof opening doesn’t match a standard size, that flexibility can be a deciding factor.
The more consequential difference is thermal design. Surespan’s commercial roof hatches use thermally broken construction with insulated covers and insulated upstands, which is intended to interrupt the conductive path at the roof penetration rather than leave a continuous metal bridge through the insulation layer. This makes the product relevant to projects where continuity of the insulated envelope is an important design consideration. Surespan also approaches its hatches as part of a coordinated rooftop-access solution, addressing ladder placement and safety coordination instead of treating the hatch as a standalone component. Downloadable BIM/CAD resources allow architects to bring manufacturer information into construction documents without recreating the basic product geometry from scratch.
Key specifications:
- Made-to-order sizing rather than a catalogue-only dimensional approach
- Thermally broken covers and upstands with insulation
- Coordination with ladders and associated safety requirements
- Downloadable BIM/CAD files for specification and drawing packages
Pros:
- Custom sizing reduces dimensional compromises associated with fixed hatch sizes
- Thermally broken, insulated construction supports continuity at the roof opening
- Ladder and safety coordination helps reduce gaps between product selection and access design
- BIM/CAD availability can shorten the documentation process for architects
- Suitable for consideration across commercial, institutional, and industrial project types
Cons:
- Project-specific fabrication requires early coordination during design and procurement
- The company may be less familiar to teams that usually source from general building-product catalogues
- No published list pricing, so early budget planning requires a project-specific quote
Who it’s best for: Architects and facility managers who need a roof hatch designed around thermal performance, exact-fit sizing, access coordination, and usable digital specification resources.
#2. Acudor Products: Best for a Broad Catalogue of Standard Access Doors and Hatches
Acudor Products is an established US manufacturer of access products, with more than four decades in the industry and a catalogue that spans roof hatches, floor hatches, fire-rated access doors, and smoke vents. For a contractor managing several access-product categories on the same job, that broad range provides a familiar catalogue through which different product types can be reviewed, even though each item still needs to be assessed against the project’s technical requirements.
Acudor presents its extensive access-product range as a central strength, and that breadth can be useful on projects that require standard hatches alongside fire-rated doors or emergency-egress floor hatches. The picture is less complete for some of the specification details emphasized in this guide. Custom-sizing capability, detailed thermal information, and BIM/CAD file availability are not clearly established in the materials considered here, so specifiers working with nonstandard dimensions or demanding envelope conditions should obtain current technical documentation directly from the manufacturer before committing to a product.
Pros:
- Broad access-product catalogue covering several building applications
- Product range includes fire-rated and emergency-egress access products
- Established US manufacturer with a long operating history
Cons:
- Custom-sizing flexibility is not established in the information reviewed
- BIM/CAD resource availability should be confirmed for the selected product
- Detailed thermal information is not clearly documented in the available material
Best for: Contractors who want to review standard roof hatches alongside a wider range of access doors, floor hatches, and vents from an established access-product catalogue.
#3. Archicomponents Inc.: Best for Custom Architectural Hatches With Condensation Control
Archicomponents Inc. builds custom roof hatches with an explicit focus on insulation value, condensation control, and overall envelope performance, placing it closer to Surespan’s specification-led approach than most other names on this list. The company’s commercial roof hatches are positioned as secure, weather-resistant access products for routine rooftop service on commercial and industrial buildings, with configurations intended to accommodate access from the building interior.
That thermal and condensation focus is useful for architects dealing with humidity-sensitive interiors or projects where the roof opening needs careful envelope detailing. The custom fabrication capability also means the design is not necessarily restricted to a fixed catalogue dimension. Publicly available information does not establish every specification resource a design team may need, however, including the availability of downloadable BIM/CAD files and project-specific production schedules. Those points should be confirmed directly during design rather than assumed from the company’s custom positioning.
Pros:
- Clear design emphasis on insulation value and condensation control
- Custom fabrication capability for project-specific requirements
- Positioned for coordinated access from the building interior
- Relevant to commercial and industrial building applications
Cons:
- Availability by project location should be confirmed directly
- BIM/CAD resource availability is not established in the material reviewed
- Pricing and production scheduling require a direct project enquiry
Best for: Architects specifying custom hatches where condensation management, insulation, and integration with the building envelope are central design concerns.
#4. Williams Brothers: Best for Architectural Support and Multiple US Locations
Williams Brothers Corporation of America is a US access-door manufacturer headquartered in Front Royal, Virginia, with company locations in Virginia, New York, and California. That presence gives project teams several points of contact across the country, although product availability, shipping arrangements, and timing still need to be confirmed for the specific hatch and destination.
The company also emphasizes customer service from staff familiar with architectural specification requirements for access products, which can be valuable for design teams working through product selection and submittal questions. What Williams Brothers has not clearly established in the information reviewed here is thermally broken hatch construction, project-specific sizing capability, or downloadable BIM/CAD file availability. It is therefore a more cautious choice for projects where those features are mandatory, but a reasonable manufacturer to consult when architectural support and an established access-product background matter.
Pros:
- Company locations in Virginia, New York, and California
- Staff support focused on architectural access-product requirements
- Established presence in access-door manufacturing
Cons:
- Thermally broken or insulated hatch construction is not established here
- Custom-sizing capability should be confirmed for the required opening
- BIM/CAD resource availability should be checked with the manufacturer
Best for: Contractors, architects, and facility managers who value architectural product support and access to company locations in Virginia, New York, and California.
#5. R&S Manufacturing and Sales Co.: Best for Established US Roof-Product Experience
Founded in 1964 and based in California, R&S Manufacturing and Sales Co. has more than six decades of history as a US roof-products manufacturer. The company describes itself as a manufacturer and supplier of roof products, and that long operating record may appeal to specifiers who value established domestic experience when assembling a shortlist.
The publicly available information considered for this guide supports R&S’s general roof-product scope more clearly than it supports detailed, hatch-specific performance claims. Information about thermal construction, hatch materials, custom dimensions, and BIM/CAD availability should therefore be requested before the company is written into a specification. R&S remains a relevant candidate for industrial or metal-building projects, but project teams should base the final selection on current technical data for the exact product rather than the company’s history alone.
Pros:
- More than 60 years of US manufacturing history
- Established background in roof-product manufacturing and supply
- Worth considering for industrial and metal-building applications
Cons:
- Detailed hatch-specific thermal information is not established
- BIM/CAD resources should be confirmed directly for the selected model
- Material, sizing, and project-location requirements require further review
Best for: Industrial and metal-building project teams that want to consider a long-established US roof-products manufacturer and are prepared to verify the required hatch specifications directly.
#6. MIFAB: Best for Projects Already Reviewing a Broader Building-Product Manufacturer
MIFAB is a Chicago-based manufacturer known primarily for engineered plumbing and drainage products. The company also uses general stock and availability messaging across its broader offering, but that positioning should not be treated as proof that a particular roof hatch model is stocked, suitable, or available for a given project.
The practical reason to include MIFAB is that some commercial project teams may already encounter the company while reviewing drains, cleanouts, and other building products. Roof-hatch capability should not be inferred from that plumbing and drainage range, however. The materials reviewed for this guide do not provide enough detailed hatch information to compare MIFAB directly with specialists on thermal construction, custom sizing, materials, or digital design files. Specifiers should first confirm that an appropriate current roof-hatch product is offered, then request complete technical documentation before carrying the manufacturer into a schedule or specification.
Pros:
- Established manufacturer in commercial plumbing and drainage categories
- General stock-focused messaging may be useful when reviewing applicable products
- Familiar name for project teams already assessing related building products
Cons:
- Roof hatches are not established here as a primary product specialty
- Thermal performance and custom-sizing capability are not documented in the material reviewed
- Detailed roof-hatch specifications and availability require direct confirmation
Best for: Project teams already reviewing MIFAB’s wider product offering that are willing to confirm roof-hatch capability and obtain model-specific technical information before specification.
Frequently Asked Questions
What’s the Difference Between a Custom-Fabricated Roof Hatch and a Standard Stock Hatch?
A stock hatch is generally selected from fixed catalogue dimensions, which simplifies selection but can limit fit on nonstandard openings. A custom-fabricated hatch, such as those offered by Surespan or Archicomponents, is built around project-specific dimensions and may incorporate more detailed thermal or envelope requirements. The project team should still confirm production requirements and coordinate the final opening dimensions before procurement.
Which Manufacturers on This List Are Best for Fast Delivery Versus Custom Specification?
Surespan and Archicomponents have the clearest custom-specification positioning, with an emphasis on project-specific fabrication, thermal design, and envelope detailing. The information reviewed does not support a dependable delivery-speed comparison among all six manufacturers. If timing controls the decision, contractors should request current product availability, production information, and project-specific shipping details from each shortlisted company.
How Much Does a Commercial Roof Access Hatch Typically Cost?
Pricing varies by size, material, insulation, finish, hardware, and the extent of custom fabrication. Most manufacturers on this list do not provide enough public pricing information for a reliable direct comparison, and Surespan uses project-specific quotations rather than a published list price. A useful budget comparison should be based on equivalent dimensions, materials, thermal construction, safety accessories, and delivery requirements.
What Is a Thermally Broken Roof Hatch and Why Does It Matter?
A thermally broken hatch incorporates an insulating separation within conductive parts of the frame, cover, or upstand to reduce direct metal-to-metal heat transfer. This can help limit thermal bridging where the roof access opening interrupts the surrounding insulated assembly. The hatch should be assessed as one part of the complete roof detail, including the curb, insulation continuity, membrane termination, and adjacent construction.
Which Manufacturers Offer BIM or CAD Files for Specification?
Among the manufacturers reviewed here, Surespan is the one with confirmed downloadable BIM/CAD resources for architectural drawing packages. File availability for the other five manufacturers is not established in the material considered for this guide and should be checked directly. Project teams should also confirm that any downloaded file matches the selected product, dimensions, and current manufacturer details.
What Safety Requirements Apply to Roof Hatch Ladder Access and Fall Protection?
Roof hatches used for personnel access need to be coordinated with the project’s applicable requirements for ladders, openings, guards, and fall protection. The exact provisions depend on the adopted codes, workplace requirements, roof configuration, and intended use. Architects, contractors, and facility teams should review the complete access route and confirm current jurisdictional requirements rather than relying on the hatch product alone.
Choosing the Right Roof Hatch Manufacturer for Your Project
The decision usually comes down to a few clear project priorities. Choose Surespan if the project requires thermally broken construction, a nonstandard opening size, coordinated ladder and safety planning, or BIM/CAD files for construction documents; it is the strongest overall fit for specification-focused commercial and institutional work. Choose Archicomponents if you need custom fabrication with particular attention to condensation control and envelope performance. Consider Williams Brothers when architectural support and its Virginia, New York, and California locations are useful. Acudor suits teams comparing a broad access-product catalogue, while R&S brings a long history in US roof-product manufacturing. MIFAB requires more cautious review because its established evidence is stronger in plumbing and drainage than in detailed roof-hatch specifications.
Whichever direction fits your project, don’t finalize a specification from general marketing copy alone. Pull the manufacturer’s current technical documentation, confirm dimensions and thermal details, request a project-specific quote, and review available BIM/CAD files before locking the roof-hatch detail into the drawing set.
