Our Service Approach

The Celoseal approach to roofing excellence is rooted in it's sincere desire to ensure total customer satisfaction while offering fair and competitive pricing within an ethical environment. Toward this end, a wide variety of advanced roofing specialties are offered including commercial, multi-family residential, diagnostic inspections, and preventative maintenance and repair.

Roofing Inspections


A high quality and thorough roofing inspection performed by a qualified roofing specialist is the first step necessary when undertaking any roofing project. At Celoseal we take great pride in offering some of the most comprehensive and complete diagnostic roofing inspection capabilities available in the industry today. Our roofing inspections are conducted by a knowledgeable and experienced company specialist who is trained to evaluate the performance of the roof and identify any roof problems or potential problem areas. Using this methodical examination method, Celoseal will provide a detailed report to you that outlines all recommended routine maintenance and corrective actions needed to maintain an attractive and water-tight roofing system.

Our comprehensive six point roofing inspections examine the following areas: 
• Roof membrane condition 
• Roof slope and drainage 
• Metal flashings
• Gutters and downspouts 
• Roof mounted equipment
• General appearance 

Ideally, regular roofing inspections should be scheduled twice per year. These inspections can minimize structural and interior damage to a building by detecting roof problems caused by extreme weather conditions in the summer and winter months. Fall inspections are designed to prepare the building and roofing system for the upcoming rainy season. Spring inspections are made to detect any damage to the roof that occurred during the winter months. Roofing systems often fail prematurely due to lack of proper maintenance and repair. Roof leeks often result in expensive interior and structural damage. Roof leaks may also threaten the safety of the building’s occupants. What is the condition of your roof? Contact us today so that we may schedule a thorough diagnostic inspection. 

Repair and Preventative Maintenance


Routine repairs and preventative maintenance can reduce roofing related disasters and maximize the value of all roofing systems. Roof repairs and maintenance are opportunities to secure the building owner’s investment. At Celoseal we believe it is better and more cost effective to take proactive measures to prevent roofing problems rather than suffer the consequences of a failed roofing system.

Our service technicians are trained to repair all types of roofs and can quickly identify the source of leaks or potential leaks. We employ the state-of-the-art repair methods that are recommended by the National Roofing Contractors Association and by leading roofing manufacturers, which is crucial because improper roofing repairs may have lasting adverse effects. The proper selection of repair materials and the repair application process are critical to ensuring long-term roofing repair solutions. 

When leaks do occur, building owners often incorrectly assume that a complete new roofing system is necessary. To the benefit of our clients, our service technicians many times are able to very effectively restore a leaking roof to a water-tight condition. A carefully designed and applied repair and maintenance program can add many years to an existing roofing system.

Our repair and maintenance specialists have an outstanding record of success and have saved our customers hundreds of thousands of dollars over the years. Contact us today to find out how we can extend the life of your roofing system through an affordable and high quality roofing repair and maintenance program.

Commercial Buildings


For more than 50 years, Celoseal has been designing commercial roofing specifications in locations throughout Southern California. Our professional approach and high quality craftsmanship has allowed us to establish Celoseal as a leading designer of commercial roofing systems. We work directly with property managers, building owners, asset managers, maintenance and building supervisors, and general contractors to design and install the best possible roofing or waterproofing system for the building. Our roofing specialists are trained in hot asphalt applied built-up and modified roofing, torch applied modified roofing systems, single-ply roofing, and cold adhesive applied roofing systems. 

We are experts in helping you to determine the proper roofing system based on several critical factors including roofing budget, building utilization and occupancy type, roof drainage and slope, condition of the roof deck and the building’s construction, roof mounted equipment, roof traffic, and local climatic conditions such as wind resistance, fire safety, protection from excessive roof moisture and airborne chemical contamination.

Relevant roof design is critical to maximizing the value of a new or existing roofing system. We believe that a proactive stance in protecting the building and its contents is the most practical approach. We have developed a Customized 5-Point Roof Design Plan (link) that assists us in selecting the most practical, functional and durable roofing system for each of our commercial building clients. In the long run, properly securing the building from water infiltration will save the building owner money and help protect the investment.
