Why El Monte Superior Roofing is the Best Choice for Roof Re-Covering Services

Our roof re-covering services are specifically tailored for El Monte's unique environmental challenges. Located in the San Gabriel Valley at just 305 feet above sea level, El Monte properties face intense solar radiation with UV index ratings frequently exceeding 10 during summer months. This extreme exposure accelerates roofing deterioration, particularly for commercial buildings in the Flair Park business district and residential properties along Valley Boulevard where shade coverage is minimal. Our re-covering solutions incorporate UV-resistant materials calibrated specifically for our region's 280+ annual days of sunshine.



El Monte's position in microclimate zone 9b creates distinct challenges with temperatures regularly exceeding 95°F for over 120 days annually, causing significant thermal stress on roofing materials. Properties near the Rio Hondo Watershed face additional challenges during our concentrated rainy season (November-March) when approximately 17 inches of annual rainfall occurs in brief, intense downpours. Our re-covering techniques comply with L.A. County Title 24 energy efficiency requirements while addressing El Monte's particular needs for thermal resistance.


The diverse architectural styles throughout El Monte neighborhoods, from older ranch-style homes in the Mountain View district to newer developments near Lower Azusa Road, require customized re-covering approaches that account for different roof pitches and existing materials common in our community. This localized expertise ensures optimal performance for re-covered roofs against El Monte's specific climate challenges.

Our Roof Re-Covering Process

We follow a thorough process designed to ensure your roof's longevity and performance. From detailed inspection to final cleanup, each step is handled with precision and care to meet both commercial and residential standards.

Roof Inspection and Assessment


Our process begins with a comprehensive inspection of your existing roof. We check for structural integrity, water damage, and underlying issues such as dry rot or weakened decking. This helps us determine if the roof qualifies for re-covering or if full replacement is necessary.


We also evaluate the current roofing material, looking for compatibility with new layers. This assessment informs our recommendation on the best approach to enhance durability and weather resistance.

Roof Material Selection


We prioritize using high-quality materials that fit the specific needs of your property and climate. Options include modified bitumen, TPO, and single-ply membranes for commercial roofs, while residential roofs often benefit from asphalt shingles or synthetic underlayments.


Our team helps you select materials based on factors like lifespan, energy efficiency, and budget. We work with trusted brands known for their durability and manufacturer warranties, ensuring a reliable roof system.

Preparation and Safety Measures


Before installation, we prepare the roof deck by removing debris and assessing minor repairs where necessary. Proper cleaning and spot repairs ensure that the new layer adheres correctly and performs as expected.


Safety protocols are strictly followed to protect both workers and occupants. This includes using fall protection, securing work zones with barriers, and complying with local safety regulations and OSHA standards.

Final Installation and Cleanup


During installation, we apply the new roofing layer with expert craftsmanship, ensuring tight seals and proper overlap to prevent leaks. For flat roofs, membrane welding and seam sealing receive extra attention to enhance waterproofing.


After installation, we conduct a detailed inspection and remove all construction debris. We also provide maintenance advice to help extend the life of your new roof covering.

Roof Re-Covering Solutions We Offer

We provide roof re-covering services designed to extend the life of your existing roof without the need for full replacement. Our methods focus on using durable materials and proven techniques to enhance protection and performance while minimizing disruptions.

Commercial Roof Re-Covering

For commercial properties, we specialize in applying new roofing layers over existing surfaces to reinforce waterproofing and improve energy efficiency. We work with materials such as modified bitumen, TPO, and EPDM membranes to suit different building types and climates. This process preserves the structural deck while upgrading the roof’s durability.



Our team assesses conditions thoroughly before re-covering, ensuring proper adhesion and ventilation. We also offer roof restoration coatings that increase resistance to UV damage and chemical exposure. These solutions help reduce maintenance costs and extend the life of commercial roofs by several years without the downtime of a full tear-off.

Residential Roof Re-Covering

In residential applications, we focus on enhancing roof protection with overlay systems compatible with asphalt shingles, metal, and flat roofing materials. Our re-covering options improve waterproofing and insulation, helping to regulate indoor temperatures and lower utility costs.



We ensure the existing roof deck is in good condition before proceeding to layer new materials. Our technicians follow industry best practices to secure flashing, seal joints, and prevent leaks. This approach offers homeowners a cost-effective way to refresh roofs that have minor wear but not enough damage to warrant replacement.
