Local Weather Impact on Roofing
Tustin's Mediterranean climate features hot summers averaging 85-87°F and mild, wet winters with 3.07 inches of rainfall in February. Your roof must resist heat damage in summer and handle occasional rain without leaks. This mix can challenge roofing materials that expand and contract across the city's 11.1 square mile area.
Sun exposure can cause asphalt shingles to crack or fade faster. Flat and low-slope roofs common in commercial buildings need effective waterproofing to prevent water pooling during the wettest months from December to March, which account for over 8 inches of annual rainfall. We recommend roofing options designed to reflect sunlight and manage moisture well, extending your roof's life in this city with 26,476 housing units.
Common Roofing Materials
You'll see several common roofing materials used in Tustin, including:

- Single-Ply Membranes: Materials like TPO, EPDM, and PVC are ideal for flat roofs on commercial buildings because of their waterproofing and flexibility serving Tustin's business community including 10 major employers.

Specialized Roofing Solutions
We provide roofing options designed to meet the unique needs of your commercial property. These solutions focus on durability, weather resistance, and energy efficiency to keep your building protected and running smoothly throughout Tustin's temperature variations.
TPO Roofing Systems
TPO (Thermoplastic Olefin) roofing is popular for its heat-reflective properties and energy savings. It is a single-ply membrane that comes in a white or light color, which helps reduce cooling costs by reflecting sunlight crucial during Tustin's summer months with temperatures reaching 87°F. TPO roofs are resistant to UV rays, chemical exposure, and punctures. They are also flexible, making installation easier on flat or low-slope roofs common in Tustin's commercial buildings. We use high-quality TPO membranes that offer strong long-term performance with low maintenance. This roofing system is a great choice if you want a durable, energy-efficient roof that handles harsh weather without cracking or shrinking.
Modified Bitumen Roofing
Modified bitumen roofing is a type of asphalt-based roofing designed to improve durability and weather resistance. It uses modifiers like rubber or plastic to make the asphalt more flexible and strong ideal for Tustin's climate conditions. This roofing is applied in layers, often with heat or adhesives to create a tough, seamless surface. It works well on flat rooftops where water drainage is minimal important during Tustin's wet winter months. You can expect excellent resistance to UV rays, temperature fluctuations, and physical damage. It's repairable and suited for commercial buildings where durability is a priority.
Single-Ply Membranes
Single-ply membranes include materials like PVC (Polyvinyl Chloride) and EPDM (Ethylene Propylene Diene Monomer). These membranes are pre-fabricated and installed in large sheets to cover your roof securely across Tustin's diverse commercial properties. PVC membranes are highly resistant to chemicals and fire, making them ideal for industrial or commercial use near harsh environments. EPDM is known for its elasticity and durability, suitable for Tustin's varying weather conditions from 46°F winter lows to 87°F summer highs. Both types provide waterproofing and are relatively lightweight. We install these membranes with precision to ensure watertight seals, reducing the risk of leaks and costly repairs later on.

Inspection and Repair Processes
We focus on thorough inspections to spot issues early and carry out precise repairs to extend your roof's life. Our approach ensures your flat roof stays strong and weather-resistant throughout Tustin's seasonal changes.
Roof Assessment Techniques
We start by examining your roof's surface carefully. This includes checking for cracks, blisters, seams, and weak spots. We use visual inspections combined with infrared technology to detect hidden moisture or heat loss, which often signals damage beneath the surface particularly important in Tustin where summer temperatures can reach 87°F.
We also assess the roof's drainage system to avoid water pooling during Tustin's rainy season. Roof slope and flashings are inspected for proper installation and wear. Our team documents all findings with photos and detailed notes to guide repairs and give you a clear report.
Leak Detection and Repair
When leaks happen, they usually start small but can cause big problems if left unchecked. We pinpoint leaks using water tests and moisture sensors to find the exact entry points crucial given Tustin's 13.87 inches of annual rainfall.
Repairs involve sealing all cracks and damaged areas with compatible roofing materials like TPO or modified bitumen. We replace worn-out flashing and reinforce weak spots. Our aim is to restore your roof's waterproof barrier with long-lasting materials and proper sealing techniques, reducing the chance of future leaks.
