Roofing could be considered the first line of waterproofing with a vast array of types and systems available. We stock a variety of specialty roofing materials for our roofing contractors needs including hot or cold patching, underlayments, flashing, reinforcement fabrics and primers.

Self-Adhered Underlayments

Ice dams are a significant contributor to residential sloped roofs leaking and self adhered underlayments have been the best solution to that problem for many years. As this has become better understood this material is no longer a “specialty” item and is almost considered a necessity for a properly functioning sloped, shingled roof. Fully adhered underlayments are one of our most popular products in our roofing division.

Synthetic Underlayments

Much stronger, lighter and longer lasting than conventional organic felts, synthetic underlayments offer a secondary protection layer under asphalt shingles to promote water shedding especially in driving rain. They are slip resistant, impermeable membranes, lightweight and easy to install. Synthetics will not rot or crack over time as traditional felt will and with the improved safety factor due to the slip resistance they give a contractor peace of mind both during and after the installation process. Synthetic underlayments can also be used as temporary roof protection due to storm damage but are considered water resistant rather than waterproof so they are not permanent fixes.

Low Slope (flat) Roofing

Unlike sloped roofs, a low slope or flat roof cannot depend on gravity to shed the water toward a gutter or drain. This requires the roofing material to be a waterproof, monolithic membrane that will keep the water out of the structure without the expectation it will drain away easily. “Flat” roofs will generally have a slight slope (less than 3-in-12) to help steer water in the direction of drains, surrounded by a parapet wall. Built Up Roofs (BUR), modified bitumen and single layer membrane roofs are the most common systems employed for these roofs.

Fluid Applied

Hot or cold fluid applied materials offer a seamless waterproof membrane for use in low slope roofing systems primarily. These products can be used to completely roof a building or as a repair material for an existing roof system.

Reflective Coatings

Reflective roof coatings not only reduce energy costs but will increase the lifespan of the roof as well. Thermal shock is reduced, which puts less stress on the roof and consequently mitigates the number and frequency of leaks. Most types of roofs are suitable surfaces for reflective coatings with the main exception being ballasted gravel roofs without special surface preparation. On top of all the other benefits, aesthetic improvement is the most obvious and can certainly be another factor in making a decision.

Tools & Accessories

Roofing systems often require ancillary items, primers, rollers, squeegees, reinforcement materials as well as many other specialty tools and accessories. Confirm with CDS Technical that you have all the materials you need before the job commences as some of these items are often overlooked.
