Emergency leak during a storm. Tarp on my roof in under 3 hours. Saved my ceiling. Permanent repair done two days later. Lifesavers.
They called me back right away. Booked the estimate in 24 hours. Clear quote. Great follow up. I will call them again for my next roof.
Replaced my whole roof in one day. Worked into the dark to finish. Left my yard cleaner than they found it.
Found missing shingles after a storm. They matched the colour perfectly. Looks brand new. Would recommend to anyone in the GTA.
Another company did a bad job before. TilTop fixed everything the right way. Honest, fast, and fair. Best roofers we have hired.
