A St. Paul contractor that works on one thing: flat roofs.
Hamlinoen building is a St. Paul roofing contractor for low-slope commercial roofs. We survey, repair, replace and maintain TPO, EPDM and PVC roofs on offices, retail centers, clinics, churches, schools, light-industrial buildings and apartment buildings of four or more units. Every replacement is quoted as a fixed price based on measured roof area, with photos and closeout documents delivered at the end.
Low-slope roofs fail in specific ways: wet insulation, open seams, clogged drains and flashing that pulls away in freeze-thaw cycles. Focusing on these roofs lets us price them accurately and repair them right the first time.
How we work
Measure first
No replacement price is given from a photo or a satellite estimate. Every quote is based on a site survey with measured areas and core cuts.
Put it in writing
Scope, price, schedule and any change are written and signed. Verbal approvals on the roof are not used to change cost.
Photograph everything
Conditions before, during and after work are photographed by section, so the closeout file shows what was installed under the membrane.
Compliance and paperwork
Owners, lenders and property managers need documents, not promises. These are provided on every project.
- Contractor registration. Commercial contractors in Minnesota register with the Department of Labor and Industry under Minn. Stat. 326B.701; registration can be verified in DLI's online lookup.
- Building permits. We apply for and close out the permit with the city, including the St. Paul DSI Commercial Reroof Requirements checklist for low-slope roofs.
- Certificate of insurance. Issued per project before mobilization, naming the owner and manager as additional insured on request.
- Lien notices and waivers. Minnesota pre-lien notice delivered as required by Minn. Stat. 514.011, and lien waivers attached to every payment request.
- Pay applications. Progress billing against a schedule of values, in AIA G702/G703 format for lender-funded projects.
- Licensed trade partners. Electrical and gas work at rooftop units is done only by Minnesota-licensed electrical and mechanical contractors.
