Next question you may be asking, “How long does a PVC roof last?” Good question. There are warranties available
from the manufacturer ranging from 10 to 25 years, so I feel like I can safely say that a PVC roof will last 10 to 25 years,
properly installed. Roof longevity depends on a variety of factors, which I'll get to in a separate article.
How much does a PVC roof cost? The question can only be answered with a series of other questions:
- Whose PVC do you want to use? There are many options out there like Sarnafil, GAF, Johns Manville, Stevens, Carlisle, etc.
- How thick do you want the new roof? 50 mil? 60 mil? 80 mil? 115 mil?
- How is it going to be installed? Fully adhered, and if so, solvent- or water-based adhesive? Mechanically attached? Ballasted?
- Are we removing the old roof? If so, how many roofs are there right and how thick are they?
- How much roof insulation, and what types are going under the new roof?
- What type of roof deck are we going over? Wood? Concrete? Steel? Lightweight insulating concrete? Gypsum?
- How tall is the building?
- How busy is the roof, meaning how many penetrations are there and many sections are there?
- Are there any parapet walls? Parapet walls require flashing which requires additional material and labor.
- How good is access to the building?
All of the above affect the cost of a PVC roof, or any type of roof for that matter. For more information, click on this link:
