Sashco Through The Roof is a premium, clear roof sealant designed to protect and seal roof penetrations, flashing, valleys, chimneys, skylights, and gutters. It provides a durable, flexible barrier that resists UV light, ponding water, and temperature fluctuations. This guide explains what the product is, where it works best, how to apply it correctly, and how to maximize its lifespan on U.S. roof surfaces.
What Is Sashco Through The Roof?
Through The Roof is a high-performance exterior sealant engineered for roof applications. It adheres well to common roofing substrates such as metal, asphalt, ceramic tile, and concrete. The formulation remains elastic as temperatures vary, reducing the risk of cracking or peeling around critical roof penetrations. Its clear appearance helps preserve the roof’s aesthetics while delivering strong, long-lasting protection against leaks.
Key Features And Benefits
- Weatherproof and UV Resistant: Stays flexible under sun exposure and temperature swings.
- High Adhesion To Roof Surfaces: Bonds to metal, shingles, masonry, and flashing materials.
- Clear Finish: Minimizes visual impact while sealing joints and penetrations.
- Waterproof After Curing: Forms a durable barrier against rain and ice damming.
- Crack-Bridge Capability: Accommodates movement without losing seal.
Common Uses On Residential Roofs
Through The Roof is suited for sealing around chimney flashing, vent pipes, skylights, gutters, ridges, and metal flashing. It’s often chosen for pitch roofs and flat roof transitions where a flexible, long-lasting seal is essential. Homeowners may use it to address small leaks caused by aging sealant at roof penetrations, degraded flashing seams, or minor structural movements that circles around joints and valleys.
Application Steps For Best Results
- Prepare The Surface: Clean the area of dust, dirt, moss, and old sealant. Ensure the surface is dry and free of loose material.
- Protect Surrounding Areas: Mask adjacent surfaces to keep a neat bead line and prevent staining.
- Prime If Required: Some substrates may benefit from a compatible primer; follow product guidelines for your material.
- Cut And Load: Load the cartridge into a caulk gun and cut the nozzle at a 45-degree angle to create a controlled bead.
- Apply Even Bead: Move steadily along the joint or seam, maintaining consistent pressure for a uniform seal.
- Tool For Finish: Use a caulking tool or gloved finger to smooth and compress the bead, ensuring full contact with the substrate.
- Allow To Cure: Let the product cure per the manufacturer’s guidelines; cure times vary with temperature and humidity.
Tips For Maintenance And Longevity
- Temperature Comfort: For best results, apply during moderate temperatures as recommended by the product label.
- Reinspect After Weather Events: Check flashings and joints after heavy rain or freeze-thaw cycles and re-seal if needed.
- Regular Inspections: Plan periodic roof inspections to identify aging sealant before leaks emerge.
- Storage And Shelf Life: Store in a cool, dry place; reseal the cartridge promptly to preserve usable material.
Safety And Storage
Always wear protective gloves and eye protection when applying caulk. Ensure good ventilation in attic or roof spaces during application. Read and follow all safety warnings on the product label. Keep away from children and avoid contact with skin and eyes. After use, cap the nozzle securely and store the product in a temperature-controlled area to prevent premature curing.
Performance Comparison And Considerations
Compared with polyurethane or acrylic-based roof sealants, Through The Roof offers a balance of elasticity and clarity with strong adhesion to typical roofing substrates. It performs well in direct sun exposure and can accommodate roof movement without cracking. For projects requiring a clear, non-opaque seal that blends with roofing aesthetics, this product is often preferred. Consider substrate compatibility, UV exposure, and the expected movement of your roof joints when choosing between sealants.
Pricing, Availability, And How To Buy
Through The Roof is available at major home improvement retailers, online marketplaces, and specialty roofing supply stores. Prices vary by size and retailer, with standard 10-ounce to 29-ounce cartridges commonly in circulation. Look for store-specific promotions or bundled roofing kits that include compatible tools. When purchasing, verify the product is rated for exterior roof use and check the expiration date for optimal performance.
