Upgrading a Leaky Asphalt Shingle Roof to a Durable Torch-On System

12125 Acadia Street, Maple Ridge, BC V2X 3B5

In this case study, Cheri contacts Vantage Roofing Ltd to replace failing asphalt shingles on a low-slope roof, preventing interior water damage.

Project Context

Cheri in Maple Ridge reached out to Vantage Roofing Ltd after discovering water stains and active leaks on her low-slope roof. Originally covered with standard asphalt shingles—an unsuitable choice for a surface that doesn’t shed water quickly—the roof’s condition was worsening, risking damage to her home’s interior.

The Challenge

The main challenge was two-fold:

  1. Roof Type Mismatch: Asphalt shingles are not designed for low-slope applications, leading to premature wear and water infiltration.

  2. Preventing Major Damage: Cheri needed the replacement completed before any significant water ingress caused structural or cosmetic damage inside her home.

Why The Client Chose Us?

Cheri selected Vantage Roofing Ltd because of our:

  • Expertise in Low-Slope Systems: We clearly explained why a torch-on membrane was ideal for her roof’s angle.

  • Transparent, Trustworthy Quoting: Our detailed estimate and open communication built confidence from the first phone call.

How We Responded?

  • Site Assessment: We conducted a thorough inspection to confirm deck soundness and roof slope.

  • Careful Removal: Existing asphalt shingles and underlayment were stripped away to expose the roof deck.

  • Torch-On Installation: A new torch-on membrane system was installed—heat-welded seams ensure a fully waterproof barrier suited to the low slope.

  • Quality Checks: Final inspections confirmed proper adhesion, drainage, and sealing at all penetrations and edges.

The Results?

  • Leak-Free Performance: Cheri now has a brand new torch-on roof that fully withstands rain and standing water.

  • Long-Term Durability: The chosen membrane carries a 20-year life expectancy under normal weather conditions.

  • Customer Satisfaction: Cheri expressed high satisfaction with the professional process, clear communication, and peace of mind knowing her home is protected.
