EPDM ROOF COATING: The best EPDM coating depends on your application and environment. We have products for roofs which get light foot traffic, products for enhanced heat reflection, and such. RoofMate HT is most popular. All repairs should be made before coatings are applied. EPDM Cleaning AND Priming using an EPDM primer is a must, before applying any coating to assure good long-term adhesion, regardless of manufactures claims. Primer is SCRUBBED into the surface, as per manufacturers instructions.

SEAMS: This is the most important area of any roof installation, repair or replacement. Three popular methods:

  1. Use Eternabond Doublestick: < -- click link for instructions. This is self-priming, longer lasting and potable water grade. After making seam, then seal outside edges of the EPDM with M1 sealant, OR
  2. Using Primer with Butyl Seam Tape: First clean the EPDM surfaces to be seamed with a Scotch-brite pad; stir primer well; then apply EPDM Primer to both surfaces by scrubbing into the surfaces with the Scotch-Brite pad; let primer dry about 10 minutes; then apply Doublestick / Seam Tape to one side of EPDM following seam tape instructions; then fold over the other side of EPDM; then begin to remove release liner and simultaneously ROLL overlapped seam WELL to fuse sealant as your go. See Video Movie of Seam Tape application process. Finishing Seam Edges: Either add M1 sealant at exposed cut edge AND,
  3. Highly recommended: Create Double Overlap Seam. on the outside surface along the exposed seam, clean and apply EPDM Primer and apply a secondary Coverstrip layer, like this.

SEAMS REPAIRS: EPDM seam failures are a common first point of aging related wear out. Old seams can be repaired and reinforced to greatly extend the life of a EPDM roof. First clean the EPDM surfaces to be seamed; apply EPDM Primer with a scotch brite scrub pad and gloves, scrubbing primer into both surfaces; let primer dry, about 10 minutes; then apply Doublestick Seam Tape in between the overlapping layers following seam tape instructions. THEN on the outside surface along the exposed seam, clean and apply EPDM Primer and apply a secondary Coverstrip layer. EPDM Coatings are applied last, over all repairs. EPDM primer should be used under all coatings.

EPDM CLEANING: The can be accomplished several methods, depending on the type of cleaning needed. The objective is to remove all surfaces contaminate and create a fresh surfaces. Burnishing with a plastic scrub pad is quick and effective. EternaClean is also effective. For very large areas, scrubbing with a mixture of TSP and bleach is used by some. Regardless, the final surface must be free of dirt and not have any powder-like residues. Follow cleaning with an EPDM Primer. Special EPDM cleaners are available which etch away a layer EPDM. These are strong materials which can harm other surfaces. Email us for more information.

EPDM MEMBRANE ADHESION: First clean surfaces to be bonded. Stir well, then apply adhesive to both surfaces with roller, and allow solvent to flash off until tacky. Then set carefully roll EPDM adhesive coated membrane into adhesive, rolling out any bubbles as you go. Detail Instructions. EPDM adhesives included water based (VOC / solvent free/ non-flammable), solvent based (greater adhesion), and M1 Sealants (for smaller repairs. Smaller areas and repairs can also use Eternabond Doublestick.

EPDM TEAR OR BUBBLE REPAIRS: Email us at sales@bestmaterials.com with a description of your repair problem for a more detailed recommendation.

Generally smaller tear repairs or (bubbles) can be made by cutting and peeling back the membrane as far as needed to get to solid adhesion areas (cut with a razor knife as needed). Clean deck and the underside of membrane as above. Prime both surfaces. Apply M1 or EPDM adhesive. Lay EPDM Membrane back and roll out bubbles. In high stress areas (most RV roofs), add mechanical fastening along each repair edge using stainless steel ring shank nails or SS staples. Clean the outer layers. Apply Eternabond RoofSeal or EPDM coverstrip, and overlap the coverstrip past the repair line 3 inches in each direction. Roll all seams using a seam roller. Alternative methods:

HOW CAN I TELL ITS EPDM? White EPDM used on RVs is white on the outside and black on the bottom. It bends and forms EASILY (and thus will wrap edges easy). A few newer motor-homes have used TPO or PVC membrane. This will be very stiff. TPO and PVC can also be melted and seams are welded, not glued. Sometimes TPO has an additional black layer on the back which has reinforcement fabric embedded in it. EPDM is not generally produced with a reinforcement.

EPDM roofing membrane (rubber roofing) is a high performance synthetic rubber (elastomeric polymer) synthesized from ethylene, propylene and a small amount of diene monomer, compounded with carbon black, processing oils and various cross-linking and stabilizing agents. EPDM roofing has been used for over 45 years, with more than 600,000 warranted roof installations and more than 25 billion square feet. Annually, EPDM accounts for over 1 billion square feet of new roof coverings in the United States, and is still the most frequently used roofing material in the marketplace. White EPDM has been installed on RV's since the early 1980's. Providing flexibility, low maintenance, ease of repair, clean appearance, noise insulation, and temperature insulation. White EPDM roofing membrane is now standard on 3 out of 4 new RV's. Now the energy efficiency of white EPDM makes it ideal for house boat roofs, mobile home roofs, and residential flat or low pitched house roofs.

Our EPDM Roofing System Features:

  • ICC-ES Evaluation Report Testing of our EPDM Materials.
  • Fire Code Approveal , FM & UL Rating Guide

  • Thermal shock durability
  • Ultraviolet radiation resistance
  • Very high wind uplift resistance - up to I-120 Factory Mutual rating
  • Ease and speed of application without special tools
  • Cold applied, non-flammable adhesive systemsRoof Top Garden EPDM Roof System

ROOF TOP GARDENS: EPDM Roofing Systems - We have Roof Garden Systems available with a variety of waterproofing options and a full line of accessories to insure a high performance system. This includes a range of membranes such as the 60-mil EPDM and TPO which are ideal for the Ultra Extensive Roof Gardens (shallow) with 15-20 life expectations. Standard Roof gardens in 4" to 8" of depth are classified as a Medium Assembly (Extensive) using 75-mil EPDM or 72-mil TPO membranes 10-15 year lifecycles, and 90-mil EPDM or 80-mil TPO membranes for 20 years. For the Intensive Roof Gardens (deep), the membrane options include 90-mil EPDM, 80-mil TPO and the 115 through 145-mil FleeceBACK membranes. Also available is an option mop down the AFX FleeceBACK EPDM membranes over two plies of base felts to provide a durable hybrid system.
