Over the past 30 years, the company’s personnel have become experts in a wide variety of Built Up, Single Ply, Steep and Green systems and is dedicated to providing the right solution to every job. BT professionals understand the intricacies of every system and have the experience necessary to deliver superior quality and service, because it matters.

Bigham Taylor’s Service Department works with building owners and managers to help maintain their building’s roof integrity, plan and execute tenant improvement, seismic retrofit and structural repair projects, as well as performing crucial Roof Analysis and Budgeting services.



Preventative Maintenance
Preventative maintenance can ward off serious leak problems and extend the service life of a roof system. BT personnel spend thousands of man-hours a year servicing buildings across northern California and Nevada.
Emergency Roof Repairs
BT personnel are available every day of the year by calling our main office — (510) 886-0197 — or our toll-free number — (800) 244-0197 — for emergency repairs. Regular clients have access to a secure portal to report roof leaks and check on service request status.
Tenant Improvements
BT boasts outstanding service, competitive rates and quick response times. Also, as a Premier Applicator for the industry’s leading roof manufacturers, Bigham Taylor is certified to work on all types of systems while maintaining the manufacturer’s warranty.
Seismic Retrofit
BT plans, manages and executes roof seismic retrofit projects, often integrating the work with other roofing needs. By merging the two jobs, often without subcontractors, Bigham Taylor is able to provide budget savings to owners and create a seamless process that reduces the impact on occupants.
Structural Work
Many projects call for structural repair work where dry rot and defects occur. BT is regularly able to integrate structural work with roofing needs, often without subcontractors, which provides budget savings to owners and creates a seamless process that reduces the impact on occupants.
Maintenance Systems & Coatings
One of the ways to extend the life of a roof system is by applying a roof maintenance system that includes a coating process and the installation of a reinforced polyester mat into a combination of asphalt emulsion and coatings. In addition to extending the life of a roof, these systems can create a Title 24 compliant roof system and reduce the heat load on a building.
Roof Analysis & Budgeting
Bigham Taylor’s long experience provides perspective and knowledge to clients who are looking for help analyzing roofs and building maintenance budgets. The company’s personnel can provide information about roof system service life expectations and how to best maintain or replace those systems.
