Why does your Lap Sealant contain petroleum distillates, yet you tell people not to use products containing petroleum distillates?
The petroleum distillate used in our lap Sealant is used strictly in the curing process. As the material cures, the petroleum distillate evaporates. When we say not to use petroleum distillates on the roof we mean products that sit on the roof (cleaners, conditioners, UV resistors, etc).

Will my Brite-Ply EPDM roof oxidize?
Yes. It's suppose to. In a dozen years it may oxidize 10% of it's thickness. This is normal. Cleaning it at least 4 times a year using a medium bristle brush will greatly help. Dicor Roof Gard will help fill in the pores of the membrane and help keep it cleaner.

Do I need special materials to maintain my roof?

What do I need to care for my roof?
Periodic cleaning (see Dicor care & maintenance instructions). We recommend you stay away from anything that smells "fruity" or "flowery". These smells will attract birds, bees, squirrels, raccoons & other "critters".

How long can I expect my roof to last?

What is the warranty of my roof?
Dicor offers a 12 year warranty for the sheeting only. The warranty covers only premature deterioration to the point of failure due to weathering only. It does not cover the original installation or the (glue, lap Sealant, Butyl tape) to install the roof. It is a pro-rated warranty. The first 5 years would include parts and labor. Years 6-12 are pro-rated for material replacement only, no labor. This warranty is offered only to the original purchaser.

Why is the warranty only offered to the original purchaser?
Due to the contingency of the warranty being that the roof be properly maintained, once a unit has changed hands several times, care and maintenance cannot be confirmed. Basic industry warranty limits are to the first owner only.

Is the warranty transferable?
No. The warranty is only offered to the original purchaser and cannot be transferred.

If you are going to buy a used unit, is there a way to tell if previous owners used petroleum distillates on the roof?
Yes, two things. First, swelling, an uneven thickness of material. Second, loose areas. Petroleum distillates will cause the membrane to swell or balloon.

My roof has air bubbles. Is this normal?
Typically, if air bubbles occur they occur during or very soon after the roof has been applied. A couple of reasons for the air bubbles would be that they were not broomed out during application, and we ask the installer not to stretch the material during installation to allow for expansion and contraction of the membrane. Air bubbles will occur with weather conditions and humidity. Air bubbles can also occur at the seams of the roof decking due to flexing and twisting that occurs during transit. Sometimes they occur if there is a significant difference in the temperature between the inside and outside of the unit.

Will the air bubble effect the performance of my roof?
No. The air bubbles will not blow up and pop. They will come and go with the weather conditions, humidity, etc. Please do not puncture the air bubbles. Air bubbles mean there is room for expansion and contraction, lessening the chance of stress cracks later.

Is it easy to repair tears in the roof membrane?
Yes. Any tear in an EPDM roof membrane can be repaired using a number of repair methods. Dicor has developed several prepackaged peel and stick repair kits that work well on tears.

If my roof has to be repaired, how long should I expect the patch to last?
If the repair is applied properly, the patch should last the duration of the membrane. It should be checked periodically.

My roof has developed mold/mildew. Can this be cleaned?
There isn't anything in the chemical makeup of the membrane that will promote the growth of mold/mildew. Dicor has developed cleaning instructions for mold/mildew. These instructions can be downloaded here. Note: It is recommended the instructions be printed and read prior to using the cleaning procedure.

Are there any other cautions concerning the roof membrane?
We would suggest you use extreme caution when working on the top of the vehicle. The wet membrane may be extremely slippery.

  • Do not use cleaners or conditioners containing petroleum distillates, harsh abrasives, or citric based cleaners.
  • Beware of areas where fruit, tree sap or harsh environmental fall-out may stay on the roof for an extended period of time. These conditions may result in unremoveable stains. You may have to increase the frequency of your cleaning or premature deterioration may occur.
