Flat Roofing Options for Replacements and Repairs
We offer a range of flat roofing materials designed to meet various needs in durability, energy efficiency, and cost. Choosing the right material depends on building requirements, weather conditions, and long-term maintenance preferences.
TPO and PVC Roofing
TPO (Thermoplastic Olefin) and PVC (Polyvinyl Chloride) are popular single-ply membrane options known for their durability and reflectivity. Both materials provide strong resistance to UV rays, chemical exposure, and punctures, making them suitable for commercial and multi-family buildings.
TPO is often favored for its heat-welded seams that reduce leakage risks and its cost-effectiveness compared to PVC. PVC offers superior chemical resistance and is slightly more flexible, which can be advantageous in areas with temperature fluctuations.
Modified Bitumen Systems
Modified bitumen roofing is a durable option combining asphalt with modifiers for enhanced elasticity and waterproofing. Its layered construction offers strong resistance to punctures and tears, suitable for buildings with moderate to high foot traffic on the roof.
Installation methods include torch-down, self-adhered, or cold-applied adhesives, providing flexibility depending on the building and site access. Modified bitumen withstands various weather conditions, including intense sun and heavy rain, with a typical lifespan of 15 to 20 years.
Built-Up Roofing (BUR)
Built-Up Roofing consists of multiple layers of bitumen alternated with reinforcing fabrics, creating a thick, waterproof barrier. BUR is well-established and valued for its reliability and fire resistance.
The layered structure makes BUR heavy but highly protective against water infiltration and mechanical damage. It is commonly finished with gravel or a reflective coating to increase durability and UV protection.

Flat Roof Replacement & Repair FAQs
How much does flat roof replacement cost in Mission Viejo?
Flat roof replacement costs $7-$13 per square foot, with most projects ranging from $8,000-$25,000. TPO systems from Firestone or GAF run $7-$9/sq ft, PVC from Sika Sarnafil or IB Roof Systems costs $9-$12/sq ft, and premium materials like Duro-Last PVC or Carlisle EPDM range from $10-$13/sq ft. Commercial buildings over 10,000 square feet see 10-15% lower per-square-foot costs. Price varies based on existing roof removal, substrate condition, and rooftop equipment density.
What are signs my flat roof needs repair?
Watch for membrane blistering or bubbling, cracked flashing around perimeters, and water ponding lasting 48+ hours after rain. Interior signs include ceiling water stains, musty odors, and increased energy bills. UV degradation appears as membrane shrinkage or surface erosion. Check for lifted membranes after Santa Ana winds. Granule loss on modified bitumen surfaces indicates advanced wear, while alligatoring (cracked patterns) on built-up roofing suggests oxidation damage requiring immediate attention.
Which flat roofing materials last longest in Southern California?
PVC membranes from Duro-Last and IB Roof Systems last 25-30 years with excellent UV resistance and flexibility for thermal cycling. TPO systems from GAF and Firestone offer 20-25 year lifespans. Single-ply membranes outperform traditional built-up roofing due to superior heat and UV resistance. 80-mil membranes provide better puncture resistance than standard 60-mil options, particularly for commercial applications. Proper slope installation (minimum 1/4" per foot) prevents water accumulation and extends service life.
How long does flat roof replacement take?
Residential flat roof replacements take 3-5 days, while commercial projects require 5-10 business days. The process includes removing existing roofing (1-2 days), repairing the substrate (1 day), installing insulation board (1 day), and applying the new membrane with proper flashing (1-3 days). Installation requires dry conditions and temperatures above 50°F. Our crews are certified by GAF, Firestone and Carlisle, ensuring proper techniques that maximize service life.
Can a leaking flat roof be repaired or does it need replacement?
Leaking flat roofs can often be repaired if damage is localized and affects less than 25% of the roof area. Isolated punctures, small tears, or flashing failures cost $350-$1,200 to repair. Replacement becomes necessary with multiple widespread leaks, significant membrane deterioration (brittleness, cracking, shrinkage), or saturated insulation. We assess using infrared moisture scanning and core samples to determine the most cost-effective solution. For roofs over 15 years old with recurring issues, full replacement typically proves more economical than continuing repairs.
