Thank you for Subscribing to Construction Business Review Weekly Brief
Lon Hansen, Vice President, Marketing and Business Development“Everything we do is built around relationships,” says Lon Hansen, vice president, marketing and business development. “Our motto is, ‘We don’t just want this project. We want the next 10 jobs.’”
The relationship-driven approach starts well before a crew reaches the jobsite. During preconstruction, ALLIANCE brings roofing and waterproofing expertise to product selection, installation methods as well as potential problem areas, allowing contractors and design teams make informed decisions early. While not a designbuild firm, ALLIANCE draws on its field and technical knowledge to guide project teams through complex decisions. Its services span commercial roofing, re-roofing, waterproofing, tenant improvements and ongoing services including 24-hour, 365-day leak response.
Helping Contractors Navigate Complex Roofing and Waterproofing Decisions
ALLIANCE’s senior team members bring recognized industry expertise in below-grade waterproofing, single-ply roofing and metal roofing. Their longstanding relationships with major manufacturers and extensive familiarity with their products help them identify potential issues and recommend alternatives when needed. For clients, that expertise can deliver meaningful savings when a product or approach creates an unexpected cost challenge.
ALLIANCE extends that expertise beyond individual project decisions through ALLIANCE University. This program consists of 11 classes that cover a variety of roofing and water proofing topics. They can also be aligned with specific project needs, giving general contractors and preconstruction teams a deeper understanding of the work before construction begins.
A recent large project demonstrates how ALLIANCE’s technical expertise and attention to detail can translate into significant client savings. When the cost of a visually preferred metal product came in significantly over budget, ALLIANCE researched alternatives from other manufacturers and identified an alternative product that could closely mimic the desired look. The switch saved approximately $2.5 - $3 million while preserving the appearance and quality the client desired.
That same attention on every project continues once work moves into the construction phase, where safety and risk management become another part of ALLIANCE’s client support. ALLIANCE maintains dedicated safety and risk management divisions that conduct weekly personnel visits on active projects. Their assessments include not only ALLIANCE’s own crews but also the conditions of other teams working adjacent to them, These assessments give clients and general contractors added visibility into jobsite risks.
Service That Earns the Next Call
ALLIANCE support continues after installation through their dedicated service division. This team handles leaks, roof maintenance, tenant improvements and other service needs. Their 24-hour, 365-day leak response ensures clients can reach a service team member when urgent issues arise.
The value of this responsiveness becomes especially clear during major Bay Area storms. The nimble structure allows ALLIANCE to respond quickly even when hundreds of leaks are reported during a single rain event. Experienced personnel from the company’s various production teams can be pulled into the service operation, significantly expanding response capacity. Teams quickly prioritize critical leaks in critical locations before working through the broader demand.
ALLIANCE’s commitment becomes especially important when something goes wrong. The company stands behind its work, people and services, and works to resolve issues and make things right. Being there when clients need support has become a source of continued expansion.
Organic growth often comes when construction professionals move to new general contractors. Previously established trust and technical relationships can open the door to new customers and project teams. The company also pursues opportunities in active markets such as data centers and healthcare while adapting to changes in the commercial construction environment.
Whether solving a roofing challenge, responding to an emergency or helping a new team make the right decision, ALLIANCE ROOFING COMPANY focuses on being the contractor clients can rely on.
Technical Judgment and Accountability in Commercial Roofing and Waterproofing
Problems with a commercial roof can begin long before installation. Materials may be selected and schedules drawn up before all site conditions are known. By the time a contractor gets involved, certain details may already be difficult or expensive to change. Early technical input can help avoid these problems, particularly on projects where roofing and waterproofing work meet at different parts of the building envelope.
Material selection is an important part of that early work. The type of membrane and how it is attached can affect cost. It also needs to be compatible with nearby building components and allow for future maintenance. An experienced roofing contractor can spot problems with a proposed system and suggest changes before work begins. This advice should support the design team without taking over its responsibilities. Knowledge of different manufacturers and approved systems also gives contractors more options to recommend when a specification needs to change.
“ALLIANCE ROOFING COMPANY, INC.’s involvement begins during preconstruction and continues through installation, safety oversight and service after completion.”
Once construction begins, coordination becomes just as important. Roofing and waterproofing crews often work alongside several other trades. Poor communication can cause delays or leave questions about who is responsible for a particular task. Field supervisors and project managers need to stay in close contact with the general contractor so that problems can be resolved quickly. There also needs to be a clear way to reach senior management when an issue cannot be settled on-site. That prevents decisions from depending entirely on one project manager or one working relationship.
Safety is another concern. Roofing crews work near roof edges and penetrations, often on sites where conditions change as construction progresses. Regular site visits help identify risks before they lead to accidents. Having dedicated safety personnel makes a difference because someone is looking at conditions across active projects, not simply checking whether individual crews are following the rules. Sharing those findings with project teams also helps general contractors stay informed about risks around the roofing work.
The contractor’s responsibility continues after installation. A roof leak can interrupt building operations, and the problem may need attention outside normal working hours. A dedicated service team can handle these calls without pulling crews away from scheduled construction work. Smaller teams can also take care of repairs, tenant-related work and routine maintenance. During severe weather, however, the number of service requests can rise quickly. Contractors need enough flexibility to bring in additional experienced workers when that happens.
ALLIANCE ROOFING COMPANY, INC. brings these capabilities to commercial roofing and waterproofing projects. The company works with general-contractor preconstruction teams before bidding, helping address technical questions while project details are still being developed. It also provides training through Alliance University. Its senior project managers have product-specific knowledge of major roofing and waterproofing systems, allowing them to support projects that involve different materials and installation requirements.
The company has risk-management staff who visit active job sites and share their findings with project teams. This keeps safety oversight connected to the work taking place in the field. Alliance Roofing also operates a separate service division that responds to leaks around the clock. When service demand increases, Alliance Roofing can bring in experienced roofing crews to handle the additional work.
With roofing and waterproofing services under one contractor, ALLIANCE ROOFING COMPANY, INC. can support projects where the two scopes need close coordination. Its involvement begins during preconstruction and continues through installation, safety oversight and service after completion. For commercial building owners and general contractors, that means access to technical expertise early in the project and a team that remains available when the roof needs attention later.
