RECURRING LEAKS
Leaks appearing in multiple areas can signal that the roof has moved beyond a single isolated repair problem.

COMMERCIAL ROOF REPLACEMENT IN ATLANTA, GA
Ameristar Roofing develops commercial roof replacement scopes around the existing assembly, drainage, insulation, rooftop equipment and building operations before selecting the new system.

QUICK ANSWER • WHEN DOES A COMMERCIAL ROOF NEED REPLACEMENT?
Replacement becomes the stronger long-term option when failures are widespread, moisture or system deterioration is no longer localized, repair spending is accelerating, or the existing assembly no longer supports the building’s performance and lifecycle goals.
COMMERCIAL REPLACEMENT STARTS WITH THE EXISTING ASSEMBLY
DO NOT SPEC THE NEW ROOF BEFORE YOU UNDERSTAND THE OLD ONE.
Commercial roof replacement is not simply a larger version of residential re-roofing. Existing membranes, insulation, deck type, moisture, rooftop equipment, drainage, penetrations, edge conditions and building operations all affect what can reasonably be installed.
Ameristar Roofing evaluates the visible roof conditions and project constraints before developing the replacement scope. The objective is to understand why the existing roof is failing, whether any sections can remain, what tear-off is required and which new assembly fits the building.
That up-front work is what separates a defensible commercial re-roofing plan from “remove old roof, install new roof,” the construction equivalent of writing “do better” on a work order.
- Existing roof assembly and visible condition review
- Drainage and low-point evaluation
- Roof penetrations and rooftop equipment coordination
- System, insulation and attachment planning
- Access, staging and operational sequencing
WHEN REPLACEMENT BECOMES THE BETTER INVESTMENT
REPAIR HAS A LIMIT. FIND IT BEFORE YOU CROSS IT.
WIDESPREAD MEMBRANE OR METAL DETERIORATION
Broad cracking, splitting, seam issues, corrosion or aging can make localized repair less reliable over time.
TRAPPED MOISTURE
Moisture within insulation or the roof assembly can change the replacement scope and may limit overlay options.
DRAINAGE PROBLEMS
Chronic ponding or poorly functioning drains, scuppers and gutters can accelerate deterioration and should be addressed in the new design.
TOO MANY PRIOR REPAIRS
A roof covered in patches may still be serviceable, but the pattern can show that maintenance spending is no longer buying enough useful life.
CHANGE IN BUILDING NEEDS
Renovations, equipment changes, energy goals or a new ownership strategy can justify moving to a different roof assembly.
COMMERCIAL REPLACEMENT SYSTEMS
SELECT THE NEW ROOF AROUND THE NEW REQUIREMENTS.
01
BUILT-UP ROOFING
Multi-ply asphalt and reinforcing layers used on low-slope commercial roofs where redundancy and proven performance matter.

02
MODIFIED BITUMEN ROOFING
Asphalt-based sheets modified for added flexibility and strength, commonly used on low-slope roofs and detail-heavy areas.

06
METAL ROOFING
Standing seam and other commercial metal systems for buildings that need durability, long-term performance and architectural impact.
EXPLORE METAL ROOFING →WHAT THE REPLACEMENT SCOPE SHOULD ADDRESS
A COMMERCIAL RE-ROOF IS AN ASSEMBLY, NOT A MEMBRANE ORDER.
01
TEAR-OFF + SUBSTRATE
Existing materials are removed as required by the approved scope so deck and substrate conditions can be addressed.
02
INSULATION
Insulation type, thickness, attachment and existing conditions are considered as part of the new roof assembly.
03
DRAINAGE
Drains, scuppers, gutters and water paths are reviewed so the replacement does not preserve an avoidable drainage problem.
04
FLASHINGS + PENETRATIONS
Curbs, pipes, walls, edges and equipment transitions require deliberate details because these areas routinely determine roof performance.
05
ROOF COVERING
The membrane, built-up, modified bitumen or metal system is selected around slope, building use, lifecycle and project conditions.
06
CLOSEOUT
Final review, cleanup and applicable manufacturer or project documentation should be part of the completed replacement.
COMMERCIAL REPLACEMENT LOGISTICS
THE ROOF CAN CHANGE. THE BUSINESS STILL HAS TO RUN.
Replacement planning should account for what is happening below and around the roof. That means understanding entrances, deliveries, tenant activity, equipment, parking and sensitive interior operations.
- Staging and material-loading locations
- Roof access and equipment protection
- Interior sensitivity to noise or vibration
- Tenant, employee and customer access
- Weather exposure during tear-off
- Phasing and sequencing where practical
COMMERCIAL ROOF REPLACEMENT PROCESS
FROM EXISTING CONDITIONS TO FINAL CLOSEOUT.
01
ASSESS
Review the existing roof, problem areas, drainage and visible project constraints.
02
DEFINE
Build the replacement scope around tear-off, insulation, system type and details.
03
PLAN
Coordinate staging, access, deliveries, operations and weather strategy.
04
PREPARE
Protect the property and establish the work sequence before removal begins.
05
INSTALL
Complete the approved roof assembly with attention to drainage and detail work.
06
CLOSE OUT
Finish cleanup, final review and applicable documentation.
COMMERCIAL ROOF REPLACEMENT FAQS
THE QUESTIONS THAT CHANGE THE REPLACEMENT SCOPE.
Can a commercial roof be overlaid instead of torn off?
Sometimes, but overlay suitability depends on the existing roof assembly, moisture, code requirements, deck and insulation conditions, number of existing layers and manufacturer/system requirements. It should be evaluated project by project.
What commercial roof systems are available?
Ameristar's commercial roof-system pages cover built-up roofing, modified bitumen roofing, TPO roofing, PVC roofing, EPDM roofing and metal roofing.
How long does commercial roof replacement take?
Duration depends on roof size, system, tear-off, deck or insulation repairs, weather, access, rooftop equipment and phasing requirements. A schedule should be developed after the scope is defined.
Can a commercial roof be replaced while the building is occupied?
Often, but the project needs a plan for access, staging, noise, debris control, deliveries, entrances, rooftop equipment and any sensitive interior operations.
Should drainage be changed during roof replacement?
If existing drainage contributes to ponding or poor water movement, replacement is the right time to evaluate whether drains, scuppers, gutters, tapered insulation or related details should be corrected.
