Roofing Materials for a Lifetime Roof
A new roof that you install can last a lifetime if the work is done properly and that includes laying a plywood decking just right and using the best roofing materials for the underlayment.
Roofing contractor Thomas Garvey, owner of Garvey Roofing has worked in cities around the San Gabriel Valley for over 30 years and has fixed mistakes that other local roofing companies have made. The underlayment they’ve chosen wound up leaking and parts of the plywood decking get soaked and slowly rot.
So take a look at what goes under your roof and supports those attractive roofing tiles, shingles or solar panels.
Whether you’re needing a roof in Pasadena, Arcadia, Bradbury or Azusa all roofs have something in common: they prevent leaks and will reduce your energy costs—if they’re properly installed.
If you’re wondering if you need a new roof or can get your roof repaired, then call Garvey Roofing for a free estimate.

Plywood Decking
Here’s where it all starts. Plywood can last for decades. It’s so simple and yet it’s incredibly durable. However, choosing decking that lays flat and hasn’t been warped is so important.
The plywood decking connects your roof to the frame of your house. It’s the decking that provides a flat plane and makes it possible for roofers to lay the underlayment and shingles flat.
Do roofers choose OSB or plywood?
One key difference is that OSB takes longer than plywood to get saturated, but once it does then it also takes longer to dry out. If OSB is exposed to chronic leaks, then it’ll break down faster than plywood.
But chronic leaks won’t be a problem if the right underlayment is used and, again, installed the right way.
Underlayment
Most homeowners or commercial building owners don’t even think to ask about underlayment. And yet it is important for the health of your roof.
There are three kinds:
- Asphalt-saturated felt
- Rubberized asphalt
- Non-bitumen synthetic
There’s a write-up on underlayment by the International Association of Certified Home Inspectors.
Keep this in mind since the sun’s heat gets trapped in the San Gabriel Valley, especially in cities between the 210 and 60 freeways like Temple City and the El Monte area or Hacienda Heights.
It’s not just rain that’s hard on roofs. The sun’s UV rays can do far more damage. Heat will make asphalt-felt deteriorate.
That’s why reflecting the heat and preventing it from coming into your attic is also critical.
So here’s another underlayment option—Therma Sheet.
Therma Sheet
This is an underlayment that helps lower the temperature in your attic. It’s a polished aluminum facing with a cell foam core and reflects up to 97% of the sun’s heat that’s bearing down on your home or commercial building.
Therma Sheet can be installed with or without airspace depending on the type of roofing material used.
Conclusion
The right foundation helps a newly installed roof last its full lifetime. The combination of decking and underlayment creates lasting protection against rain—and heat, the biggest culprit.
