Why should I consider a roof restoration vs. a tear-off of the existing roof?

An experienced consultant can locate problem areas and an Approved APOC contractor can repair the wet insulation and damaged deck at a fraction of the cost of a complete tear-off and replacement.

Why should I consider roof restoration vs. a re-roof?

Restorations are fully adhered to the existing roof membrane. As a result, they do not allow the lateral transmission of water between roof layers. This means that leaks are easier to find and the roof can then be maintained. If water can travel between roof layers, leak locations can be very difficult to find and expensive to fix.

How soon after installation can a new asphalt/blacktop parking lot or driveway be sealed?

We recommend you wait at least 6 months including one full summer season prior to sealing to allow it to fully cure and weather. After 6 months use the water bead test to determine if the surface is ready to be sealed: spray water across the surface; if it forms beads, it is not fully cured and not ready to be sealed yet, so you’ll have to wait a bit longer.

How soon after sealing can I drive on a blacktop surface?

Under most conditions you can drive on asphalt 24-48 hours after the last coat is finished. There are a few issues to note that affect dry time: 1) Areas in full shade will take longer than areas in full sun. 2) Cooler temperatures below 80° F and higher humidity above 50% can add up to 12 hours to the full cure time. 3) Driveways & parking lots with many cracks take longer; the more cracks and the deeper the cracks, the longer it takes to cure. 4) Thicker coats slow dry time. We always recommend two thin coats for best results.

Should an asphalt surface be hot or cold when applying sealer? Wet or dry?

A hot, dry parking lot or driveway above 95° F will dry too fast; the result can be a very uneven finish. We recommend cleaning the surface first, which also serves to cool off the surface. Make sure there is no puddled water before sealing. If the surface is too cold means the sealer will not set and cure properly. For best results we always recommend application at 65° F or higher for several hours before application, to ensure the surface is warm enough to allow a proper protective film. Shady areas, high humidity or cloudy conditions can slow the cure time of the sealer, so additional dry time between coats may be needed.

Why do I need 2 thin coats? Won’t one thicker coat work?

Applying two coats of any sealer will dry and create a better finish much better than one thick coat. These sealers are water based, and they cure and form a film primarily during the evaporation of water from the coating. A thin coat will evaporate much faster and create a single uniform layer. A second thin coat will fill in areas not filled by the first coat and create a deeper, richer, more uniform coat. Single thick coats cure less evenly, have a tendency to puddle, and are prone to tracking.

Can puddles harm my waterbased coating?

Yes. If your roof has any areas where rain water gathers and forms pools, your waterbased coating will not do its job properly. For one thing, these puddles can gather dirt and other debris which could restrict your coating's reflective ability. Constant exposure to standing water can cause cracking, peeling and holes in the protective coating. It is essential that you make sure to keep gutters clear and that any roof you intend to use a waterbased coating on has the appropriate slope required to provide positive drainage and eliminate puddles entirely.

Can thinners be used on my roof coatings?

It is highly unadvisable to use any kind of thinner when applying cool roof coatings. In fact, you may be in violation of federal regulations by doing so. Besides, these roof coatings come ready to use, so there really is no need to add anything before application. Make sure that any necessary cleaning of associated brushes or other items used to apply the coating are done using water. If thinners do make their way into roof coatings, they may experience a shorter lifespan. Additionally, the coating of your roof may appear uneven as a result of exposure to thinners, and blistering and peeling could become more commonplace. The possibility of mold growth may also be heightened by the use of thinners.

Can I use these coatings on any type of roof?

Every one of our products has a label which indicated the roof types on which it can be used safely. Not every coating is right for every surface, and one that is fine for use on plywood may not be safe for tar paper or asphalt roofs. Before using any coating on any roof, you should read the label, and if you are still unsure, contact the manufacturer directly to avoid any problems or the potential voiding of your roof's warranty.

What about a rubber roof?

First, you need to determine whether or not your roof is truly a Rubber Roof (aka EPDM) or if it is a “Rubber Modified” Asphalt Roof. In roofing the terminology “Rubber Roof” is loosely used and can have various meanings. As for the use of coatings, APOC products can be used on all types of Rubber Roofs including true “EPDM Rubber Roofs.” When applying to an EPDM Rubber Roof, APOC 295 Primer must be used prior to application of coatings. Some rubber roofs are amenable to the use of acrylic latex elastomeric coatings, while others most certainly do not. It is always best to check with the manufacturer before you use any coating. If your rubber roof is able to use our coatings, be sure it is completely clean before application. Remove any and all chalking, dirt or dust. You may want to consider a professional powerwashing as well to ensure all mildew is eliminated. As with all product applications, it is probably advisable to test a small area of the roof, specifically in an especially damp or shadowy area of the roof before applying to the surface as a whole.

How do I tell the difference between a Rubber Modified Asphalt Roof and an EPDM Rubber Roof?

Contact APOC and we will be more than happy to help you with this.

Will this coating provide complete protection against leaks?

No system of protection is 100 percent foolproof and even the best coating materials will lose their effectiveness over time. However, if your roof is built properly, with good materials, and allows for proper drainage of any rain water to prevent pooling from taking place, then adding our coating will certain decrease your chances of having a leak. Remember that it is essential to always keep your drains clear and to repair any cracks or small leaks with the right kind of cement as soon as you are aware that they exist. The sooner you catch these problems, the better your chances at fixing them.

How will use of cool roof coatings affect my heating bill?

In the winter, the earth is farther from the sun that in the summer. Additionally, days are shorter and the sun is lower in the sky. That is, if there aren't clouds in the sky obscuring direct sunlight in the first place. All of this adds up to less heat entering your home through the roof. If anything, in the winter, heat enters houses through windows. After a snowfall collects on your roof, the amount of sunlight it receives may be eliminated completely. Cool roof coatings have no impact on your winter heating costs. They only limit the amount of heat coming into your building during the summertime.
