Reviews
A Quick Look at Customer Sentiment
Customers overwhelmingly praise Excelsior Roofing for their exceptional expertise, prompt and efficient service, and remarkable professionalism. Many reviews cite impressive communication, meticulous cleanup, and innovative problem-solving—from detailed consultations by Mark and Eduardo to success with complex projects like skylight installations and tar/gravel roofs. Although most feedback is highly positive, one concern was raised about unpermitted work and hazardous conditions near a school, highlighting an area for improved adherence to permits and community safety protocols.
Deep Dive: Detailed Analysis of Customer Reviews
We’ve gathered and analyzed reviews from real customers across the web to give you an in-depth look at their experiences with Excelsior Roofing Co.. Here’s what people are saying about their service quality, professionalism, and reliability:
Overall Experience & Satisfaction
The majority of customers report a high level of satisfaction with Excelsior Roofing. Homeowners appreciated the quality of work and the visible care taken from start to finish. Many noted that the finished roofs not only met, but often exceeded their expectations. However, one review raised serious concerns about unpermitted roofing work near Francis Scott Key Elementary School and issues with nearby double parking, emphasizing the impact on community safety.
Service Quality & Expertise
Clients consistently highlight the team’s outstanding technical expertise whether installing new tar and gravel roofs, handling repairs for leaky skylights, or integrating complex features like solar tilt rack anchors. Experienced crew members such as Mark, Eduardo, Roberto, and others were frequently mentioned for their deep knowledge and commitment to doing the job right the first time. Their ability to diagnose problems—from hidden wood rot to malfunctioning drains—demonstrates commendable proficiency and innovative problem-solving skills.
Customer Service & Communication
Reviewers frequently commend Excelsior Roofing’s communication and customer service. Customers reported prompt responses, often within an hour, and clear, detailed explanations during consultations. Personal interactions with staff members were noted as friendly and informative, with many customers appreciating before-and-after photos, regular updates, and courteous on-site explanations from foremen and managers alike.
Value for Money & Pricing Transparency
While Excelsior may not always be the cheapest option, many customers felt that the pricing was fair given the high quality and reliability of the service. Clients appreciated the transparent bidding process and detailed estimates that compared fixed and variable costs. The add-on value in extras such as improved insulation, custom skylight solutions, and comprehensive clean-up further bolstered the perception of good value for the investment.
Timeliness & Efficiency
Timeliness is a recurring theme in the reviews, with many customers noting that appointments were easily scheduled and that the teams arrived on time. Whether completing full roof installations in two or three days or swiftly diagnosing and addressing leaks, the efficiency was a strong point. Although one project experienced a slight delay because of high demand, the overall consensus was that the work was completed promptly without sacrificing quality.
Professionalism & Trustworthiness
Professionalism emerges as a key strength for Excelsior Roofing. Clients spoke highly of the uniformed, union-trained workers who maintained a respectful and ethical work environment. From the initial consultation by knowledgeable staff members to follow-ups and warranty services for leaks, the company built trust by offering honest assessments and standing behind their work without unnecessary upselling.
Facility, Environment & Ambience
Though primarily a service-based company, multiple reviews mentioned the impressive state of the worksite. Customers were delighted to find that their properties were left cleaner and in better condition than before the work commenced. Extra care was taken in tidying up debris and ensuring that the construction area did not disrupt the overall ambience of the home or building.
Accessibility & Convenience
The process of engaging with Excelsior Roofing was described as convenient and customer-friendly. Clients found it easy to schedule consultations and appreciated the accessibility of key staff members via phone and email. The promptness of appointments and the willingness of the team to accommodate specific project needs further enhanced the overall customer experience.
Problem Resolution & Follow-up
Excelsior Roofing earned accolades for their effective approach to problem resolution. Whether fixing leaks, addressing issues with skylights, or diagnosing hidden drainage problems, the team was proactive in identifying and resolving issues. One review specifically noted the team’s commitment to a free re-inspection in the event of recurring leaks, demonstrating a reliable follow-up process that reassured customers of their ongoing support.
Unique Strengths & Areas for Improvement
Unique strengths of the company include its decades-long experience, the depth of technical expertise, and the personable, honest approach of its staff members. Reviewers appreciated the innovative integration of additional features (such as UV resistant insulation and solar solutions) and the commendable work ethic of the entire crew. However, one notable area for improvement involves better regulatory compliance, as one review raised concerns about unpermitted work and the resulting safety implications in a community setting. This feedback suggests that while the company excels in technical performance, attention to permitting and community standards could be enhanced.
