Commercial Roof Replacement
Planned Around Your Building
When a roof is past saving, Bloom specifies the system against what your building does to its own roof, then plans tear-off, staging and work windows around the people and operations below.
Confirm the Scope Before Committing to Replacement
The right approach depends on the existing roof assembly, moisture conditions, deck condition, drainage and project requirements. Different roof areas may need different responses, so evaluate the building before assuming a full replacement is necessary.
A recover adds a new system over an existing assembly that can carry it. A tear-off removes specified materials so the conditions underneath can be addressed. Verified conditions, code and manufacturer requirements decide which one you get. Further investigation may be needed first, and restoration is sometimes worth comparing.
How a Replacement Project Runs
Evaluation and scope
Review the existing assembly, conditions and project requirements, then define the proposed scope and system.
Coordination and phasing
Plan staging, access, work sequencing and temporary weather protection around the building and its operations.
Installation and closeout
Install the agreed assembly, complete required inspections and hand over the project documentation.
Choosing the Right System
Bloom installs TPO, EPDM, PVC and modified bitumen. System selection considers exposure, drainage, roof traffic, attachment, building requirements and manufacturer specifications. Compatibility must be confirmed for the actual conditions.
TPO
A heat-welded thermoplastic single-ply membrane, commonly supplied in light colors.
EPDM
A synthetic rubber single-ply membrane, available in wide sheets and installed with adhered, fastened or ballasted methods.
PVC
A heat-welded thermoplastic single-ply membrane, with formulations and reinforcement that vary between products.
Modified bitumen
A multi-ply asphalt-based system, often chosen where a thicker, layered assembly suits the building.
What Affects the Cost
Replacement pricing depends on the building and the details more than on area alone. The scope is priced after the roof has been reviewed.
Access and staging
Where lifting equipment and materials can be positioned, and what must be protected to get them there.
Building height
Height affects the lifting equipment and how long it is needed.
Deck type and condition
The deck affects attachment methods, and deterioration found during work can add scope.
Existing layers
The number of existing roofs and whether any suitable insulation can remain affect removal and material quantities.
Details and penetrations
Curbs, stacks, ducts and other penetrations each require their own detailing.
Code and insulation requirements
The project must account for applicable code, permit, insulation and detail-height requirements. Confirm those requirements for the jurisdiction and proposed scope with the responsible project professionals.
Warranty and Care After Installation
Available manufacturer and workmanship coverage, eligibility, exclusions and owner obligations should be confirmed in writing for your project. Warranty terms vary by system and manufacturer.
Plan for maintenance after installation from the start, so visit records are kept alongside the warranty documents.
Questions About Roof Replacement
Should I repair or replace my commercial roof?
The decision should follow the condition of the assembly, not age alone. Repair may suit limited problems on a serviceable roof, while widespread moisture or deterioration can call for a larger scope. An inspection helps establish which applies to each roof area.
How will a reroof affect my building?
Work is sequenced and phased for the project, with temporary weather protection planned. The effect on operations depends on access, staging, details and weather; the proposal should describe the phasing so you can plan around it.
Will a reroof require added insulation?
It may. Applicable energy code and permit requirements can affect insulation and detail heights. Confirm those requirements for your jurisdiction and scope with the responsible project professionals.
Can the new roof go over the existing one?
A recover may be possible where the existing assembly is suitable and code and manufacturer requirements allow it. Verified conditions decide whether recover or tear-off is appropriate.
