Roof Deck Protection

Roof Deck Protection is very similar to a Leak Barrier.  The difference is that Roof Deck Protection is installed on the entire Roof Deck area instead of only on "special areas" as we mention in the Leak Barrier section.

Typically, Roof Deck Protection is a step lower in quality than a Leak Barrier.  As with Leak Barriers, there are many different types of Roof Deck Protection available to choose from ranging from basic felt/tar paper to advanced rubber based membranes with adhesives.  Choosing a reliable Roof Deck Protection is an important part of a Quality Roof System.

A word of caution; most roofing companies in Calgary use felt paper as Roof Deck Protection.  Although using felt paper is a standard and acceptable practice, some issues can arise if the felt paper becomes wet during or after the installation.  Ever notice how paper tends to curl when it dries after it was wet?  In a similar way, felt paper can curl if water or excess moisture touches it.  For this reason, and because the cost is quite small, we recommend installing a higher quality Roof Deck Protection such as a GAF/ELK Deck Armour.  For a relatively small additional cost, you'll be rewarded with a much more reliable Roof Deck Protection.

Ask your Calgary Roof Hospital representative about which under-layer would be best for your Roof System.
