The Sashco Through The Roof is a premium roof sealant designed to stop leaks and protect roof penetrations. This review compiles practical insights from product specs, expert testing, and user feedback to help homeowners decide if it fits their repair needs. It covers surface compatibility, application tips, drying times, pricing, and how real-world users rate its longevity and value.
What Is Sashco Through The Roof
Through The Roof is a silicone-based sealant engineered for exterior roofing applications. It remains flexible, adheres to a range of materials, and forms a durable, weatherproof seal around vents, flashings, skylights, and flashing seams. The product is marketed for long-lasting protection against UV exposure, temperature fluctuations, and ponding water, making it a popular choice for stubborn roof leaks.
Key Features And Benefits
Excellent weather resistance and UV stability are highlighted attributes, helping the sealant maintain elasticity and seal integrity over many seasons. Strong adhesion to asphalt, metal, wood, and certain plastics enables reliable performance on varied roof substrates. The silicone composition contributes to improved waterproofing in high-traffic or exposed areas where membranes might crack. Some formulations are noted as paintable after cure, allowing color matching to roof trim or flashing if desired.
How It Performs On Different Roof Surfaces
On asphalt shingles, metal, clay or concrete tiles, and EPDM membranes, Through The Roof aims to provide a flexible, long-lasting seal. Users report it handles irregular joints and small gaps effectively, with minimal shrinkage. The sealant tolerates seasonal temperature swings, remaining pliable rather than cracking. For flat or low-slope roofs with persistent leaks, the product is commonly applied around vent pipes, skylights, and seam intersections for reliable sealing.

Application Tips And Drying Time
Preparation is key: clean the surface free of dirt, dust, and oil before application. Apply the sealant in a steady, continuous bead around the target area, then smooth with a caulking tool or finger for a uniform finish. Typical cure times range from 24 to 48 hours in dry, moderate conditions, though heavy applications or cooler climates may extend curing. Surface reactivity with certain cleaners or paints may vary; always test on a small area if color compatibility is a concern.
Pros And Cons From Real-World Use
- Pros: Long-lasting waterproofing, strong adhesion across roof materials, stays flexible under temperature changes, durable against UV exposure, paintable after curing (subject to manufacturer guidance).
- Cons: Higher price point relative to basic sealants, requires dry conditions for optimal cure, careful surface prep is essential, some users report strong odor during application in enclosed spaces.
Pricing And Availability
Through The Roof is sold through home improvement retailers, roofing suppliers, and online marketplaces. Prices vary by tube size and formulation, but it generally sits at the premium end of exterior sealants. Buying in larger quantities or bundles can yield cost savings. Availability may differ by region, with specialty roofing stores offering expert advice and matching colors when applicable.
Sashco Through The Roof vs Competitors
Compared with standard roofing sealants, Through The Roof emphasizes long-term flexibility and UV resistance. It typically outperforms generic silicones on durability and adhesion, especially in roofline joints exposed to sun and weather. When pitted against polyurethane-based products, it may offer better elongation and weatherproofing in certain climates, though cure times and clean-up experiences can differ. For users needing a paintable finish, confirm the exact product line and curing guidance, as options vary by formulation.
User Feedback And Common Questions
Most reviewers praise the product for sealing stubborn leaks and holding up under harsh weather. Positive notes often point to ease of application and visible results within a day or two. Critical feedback frequently mentions price and the necessity of thorough surface prep for best adhesion. Common questions include whether the sealant is paintable, how long it remains flexible in extreme cold, and which roof materials it adheres to most reliably. For best results, follow the manufacturer’s instructions and use compatible primers or cleaners when recommended.
