Flat Roof Systems Tucson AZ

Challenge

Homeowner's 1,800 sq ft modern home featured a 12-year-old black EPDM flat roof that was failing. Multiple leaks during monsoon season had caused $3,200 in interior damage. The black membrane absorbed intense heat, causing roof surface temperatures exceeding 180°F and driving summer cooling costs to $380 monthly. Existing drainage had two ponding areas that accelerated membrane deterioration.

Solution

We performed comprehensive roof assessment and recommended complete replacement with white 60-mil TPO membrane system. Installation included complete tear-off of failed EPDM, new tapered polyiso insulation creating 1/2-inch per foot slope eliminating ponding, four strategically placed roof drains with overflow scuppers, mechanically-attached white TPO with heat-welded seams, and upgraded parapet flashing. Our crew completed the installation in 3 days with zero weather delays.

Challenge

Commercial property owner's 3,500 sq ft office building had a 22-year-old built-up tar and gravel roof with extensive cracking, blistering, and multiple leak points. Previous patch repairs totaled $8,500 over 5 years. The aging roof required complete replacement, but the owner needed cost-effective solution to fit limited budget while ensuring long-term reliability for their tenant.

Solution

We recommended fully-adhered black EPDM system as the most economical choice providing 25-30 year lifespan. Project included complete removal of 5-ton tar and gravel system, deck inspection and repairs to 3 soft spots, new 2.5-inch polyiso insulation (R-18), fully-adhered 60-mil EPDM membrane with seamed edges, new metal edge flashing and counter-flashing, upgraded 6-inch roof drains (existing were undersized 4-inch), and comprehensive 5-year maintenance plan. Completed in 5 days including cleanup.

Challenge

Commercial retail center's 8,500 sq ft black EPDM roof was 16 years old and showing signs of aging. While the membrane remained structurally sound with no major leaks, UV exposure had caused surface chalking and minor deterioration. The property manager faced a difficult decision: invest $55,000-$68,000 in complete roof replacement, or explore restoration options. The black roof absorbed intense heat, driving summer cooling costs to $1,850 monthly for the 6,500 sq ft conditioned space. Tenants complained about inadequate cooling during peak summer months despite the HVAC system running continuously.

Solution

After comprehensive roof inspection confirming the EPDM membrane's structural integrity, we recommended professional silicone coating restoration as a cost-effective alternative to replacement. The project included thorough pressure washing removing all surface contaminants and oxidation, repair of 12 small membrane punctures and edge details, complete seam reinforcement with polyester fabric and coating, application of premium silicone roof coating at 30-mil thickness (two-coat system), installation of reflective white finish coat, upgraded edge flashing and termination details, and new walkway pads protecting coating in maintenance areas. Installation completed in 5 days with minimal disruption to operating tenants. Total investment: $22,100 ($2.60 per square foot).
