Ratings & Reviews for Sashco Through the Roof 10.5-oz Exterior and Specialty Clear Paintable Synthetic rubber Caulk
Ratings may include incentivized customer reviews.
What Customers Are Saying
Customers overwhelmingly praise this roof sealant for exceptional leak-stopping performance, with many reporting sealed gaps, flashing, gutters, and siding lasting five years or more through heavy storms. Reviewers consistently describe it as durable, tough, and versatile across metal roofs, vinyl siding, and vent pipes. Most find it easy to apply and appreciate its paintable finish. However, some report the caulk is extremely thick and difficult to squeeze from the tube, and several note the advertised wet-surface application claim is misleading—the product fails to adhere during rain or wet conditions. Despite these application concerns, the vast majority consider it a top-tier solution for urgent roof repairs.

This Stuff Sticks
Would RecommendThrough the Roof works great on asphalt shingles. It sticks, it's thick but manageable, and stays flexible. It does not create a mess! It does reflect sunlight so, if that bothers you, keep this mind or throw some shingle granules onto your repair.

Makes job look neat and clean.
Priced a bit on the high side, but makes your job look much better than the black tar that’s the alternative. Excellent quality and worth the money.
