Roof planning for commercial buildings in Ohio and Michigan
A commercial roof protects tenants, inventory and equipment, and it is one of the largest capital items on the building. Leaks in the middle of a lease are expensive in ways that never show up on a roofing invoice.
What we hear most from commercial buildings
- Leaks over tenant space, inventory or electrical equipment
- Rooftop HVAC and service traffic damaging the membrane
- No written record of what the roof is, how old it is or what has been fixed
- Surprise capital requests when the roof finally fails
- Bids that price different systems and warranties
A plan that works
- Inventory the roof: system, age, area and leak history.
- Start an inspection program, spring and fall.
- Use a moisture survey to decide repair, coat, recover or replace.
- Budget five years out and bid with one written RFP.

Office, retail and mixed-use roofs
Tenants change the math
A leak over a tenant space can trigger rent abatement, inventory claims or a lease dispute. Check each lease for who pays for roof repairs and replacement, and how much notice tenants must get before work.
Rooftop equipment is the weak spot
HVAC curbs, exhaust fans, conduit and service traffic cause a large share of membrane damage. Walkway pads to each unit and a rule that service techs report roof damage cost little and prevent a lot.
Energy code at replacement
A full replacement can require added insulation to meet the current energy code, which changes the cost and the height of edge metal and curbs. Ask your building department and each bidder how it applies to your roof.
Put these in your bid package
- Roof plan with areas by section
- Existing system and number of layers
- Moisture survey results and wet-area replacement
- Insulation to meet current energy code
- Curb, penetration and edge-metal details
- Tenant notice, access and after-hours work
- Warranty type: manufacturer system or material-only

Questions from commercial buildings
How often should a commercial roof be inspected?
Twice a year is common, spring and fall, plus after major storms. More often around heavy rooftop equipment or kitchen exhaust.
Is a coating cheaper than replacement?
Often, when the roof qualifies: a mostly dry, sound roof with a compatible membrane. Our commercial roof cost planner puts planning ranges side by side.
What should a roofing RFP include?
Roof areas and systems, the scope you want priced, insulation and code requirements, warranty, schedule, safety rules and insurance requirements. The RFP generator builds it.
