New roof installations designed for Pasadena's climate — proper deck preparation, quality underlayment, material selection matched to your property, and a clear written estimate before any work begins.
A new roof installation is one of the larger investments a Pasadena property owner makes. Getting it right from the beginning means more than simply laying new material over the existing deck. It means evaluating the deck condition, selecting underlayment appropriate for the roofing system, planning flashing details at every penetration and transition, and ensuring drainage works properly for the roof's slope and configuration.
Whether you are building on a new property, installing a roof on an addition, or replacing a system that has reached the end of its service life, TSPO Roofing begins every installation project with a complete on-site property evaluation — not a phone estimate based on square footage alone.

The right roofing system depends on your property type, roof slope, structural capacity, drainage configuration, and budget. No single material works equally well for every Pasadena home or commercial building.
Architectural shingles are widely used on residential properties across Pasadena, Hastings Ranch, and East Pasadena. Installation includes starter strips, proper alignment, valley flashing, ridge and hip caps, and ventilation review. In Pasadena's hot climate, selecting shingles with appropriate UV ratings matters for long-term performance.
Tile roofing is common on Spanish-style and Mediterranean architecture throughout South Arroyo, San Rafael Hills, and older Pasadena neighborhoods. Tile installation requires structural confirmation of the roof deck's load capacity, appropriate underlayment, battens where specified, and careful flashing at chimneys, skylights, and wall transitions.
Standing-seam and exposed-fastener metal roofing systems suit certain Pasadena property types and are durable in high UV and wind conditions. Metal expands and contracts with Southern California's temperature swings, so fastener selection, panel layout, and penetration details all affect long-term performance. Reflective metal options can reduce heat absorption.
Flat and low-slope roofing is common on commercial properties near Downtown Pasadena and Old Pasadena, and on residential structures with flat sections. Proper drainage design is essential — ponding water shortens membrane life significantly. We evaluate slope, drain placement, and substrate condition before selecting the appropriate system.
TPO membranes are a practical option for commercial flat and low-slope roofing. Heat-welded seams, perimeter flashing, drain and scupper integration, and penetration details are all critical components of a properly installed TPO system. Cool-roof grade TPO can help reduce heat gain on Pasadena commercial buildings exposed to sustained summer sun.
Underlayment is not optional and not uniform. Self-adhering underlayment products, synthetic underlayments, and felt systems each have appropriate applications depending on the roofing material, roof slope, and project requirements. The deck beneath must also be sound — damaged sheathing is identified and replaced before installation proceeds.
Every installation follows a planned sequence — from property evaluation through final cleanup. Here is what to expect at each stage.
We assess the roof slope, deck condition, drainage configuration, existing penetrations, and ventilation. Material options are discussed based on what suits your specific property.
You receive a detailed written scope covering materials, work sequence, permit requirements where applicable, and total cost. No phone estimates or guesswork.
Damaged or deteriorated sheathing is identified and replaced before any new roofing material goes down. Property protection — landscaping, driveways, surfaces — is in place before work begins.
Underlayment, roofing material, flashing at all penetrations and transitions, ridge and hip details, and drip edge are installed according to the agreed scope and applicable specifications.
Where permits are required, inspection is coordinated with the applicable building department. We manage the scheduling and documentation required for permit sign-off.
Magnetic nail pickup, debris removal, and a final site walkthrough confirm the property is in proper condition. Completed work is documented with photographs before we leave.
Several local factors influence material selection, installation method, and permit requirements for Pasadena roofing projects.
Pasadena's extended summers subject roofing materials to prolonged UV radiation and heat. Material selection should account for heat and UV resistance — particularly for asphalt shingles and membrane systems that degrade faster in high-temperature conditions without appropriate ratings.
Santa Ana wind events create wind uplift conditions that affect fastening patterns, material selection, and installation details. Properly secured shingles and tiles, with appropriate flashing at edges and penetrations, provide better resistance to wind-driven rain and uplift.
Clay and concrete tile are significantly heavier than asphalt shingles. Before installing a tile system on a property that previously had lighter roofing material, the structural capacity of the roof framing and deck must be confirmed. This is evaluated during the property assessment.
New roof installations in Pasadena typically require permits from the City of Pasadena Building and Safety Division. California's Title 24 energy code includes cool-roof provisions that may apply to your project. We identify applicable requirements during planning and coordinate permit submissions where required.
Whether you are building new, adding to an existing structure, or replacing a system that has run its course — contact us to schedule a property evaluation. Material options and written estimates follow after we see the roof in person.
