8.5 foot wide x 400 foot long EPDM Roll
EPDM Membrane EPDM roofing lasts 20 to 25 years and has been in use since the 1960's and has been proven to last well on RV roofing applications, as well as being the easiest roofing type to install.
Single-Ply Membrane More durable than double-ply membrane (rubber with black bottom and white top)
Less likely to crack than other membrane types, however it absorbs more heat than TPO and PVC roofing
Color White, same throughout the entire surface.
Textured Surface for better traction install with the textured size facing up and the smooth side down toward the roof (facing glue) however the rubber may be installed with the smooth side down if you wish.
PRECAUTION ON ALL PRODUCTS This material in the liquid or vapor phases is extremely flammable. Keep away from sparks and open flame - do not smoke by this product. Avoid prolonged breathing of vapors of this product - use in a well ventilated area. Prolonged breathing of vapors may cause headaches and even unconsciousness.
Direct contact of uncured sealant irritates eyes and may irritate skin. In case of eye contact flush eyes with water for 15 minutes and call a physician. In case of skin contact, thoroughly wash skin with soap and water. Material may be harmful or fatal if swallowed. If swallowed, do not induce vomiting. Seek medical attention immediately.
Membrane Ships Folded Depending on size of kit you will get one or two boxes (glue / membrane)
Membrane Length / Width It is recommended to get a size that is longer / wider than your unit due to possible curve of the roof, raised or lowered areas, removing the excess is much better than not having enough.
Membrane must be installed onto clean wooden surface, do not install on top of existing membrane, glue, etc.
1. Router all vent and accessory openings. Sand all openings, seams, and edges to a smooth finish. Remove all debris off roof with air hose.
2. Apply seam tape (2” minimum width) evenly onto roof and sidewall to cover any sharp edges, it is required that seam tape be used to avoid edge splits. (We do not provide seam tape due to different sized needed)
3. Make sure all screw heads and surfaces are smooth and level throughout, raised screws will snap and puncture membrane and is not covered under warranty.
As soon as possible, while on top of clean unit remove membrane from box, do not drag over edge of unit.
1. Do Not allow membrane to touch ground or dirty surfaces.
2. Do Not allow membrane to touch sharp objects or surfaces, including lifted screw head and edges. 3. Do Not drag the membrane as this can cause punctures and tears which is not covered under warranty.
4. Membrane can be glued either side down. Single-Ply membranes are the same color throughout.
Membrane Installation
1. Cut the membrane to fit roof length with an excess of at least 6” front and rear.
2. “Bed Sheet” the membrane. That is, fold it in half so half of the roof is exposed.
3. Apply adhesive in a wet film thickness of 8-10 mils with a short-napped paint roller to the exposed half of the roof. (1 gal. will cover approximately 160-200 sq ft.) brush can be used but is more difficult. 4. Lay the roof membrane over the wet adhesive, the membrane needs to be adjusted both in width (side to side) and length (front to rear) to ensure the membrane is as flat as possible before the squeegee process. Let surplus material drape over the side of the unit for perimeter finishing.
5. Remove all air pockets and wrinkles with a squeegee (gray neoprene head will not streak), linoleum roller; press firmly working from the center outward toward the edges, do not be on the roof during this time.
6. All wrinkles must be removed at this point for a quality installation. The roof will tighten and conform as the adhesive cures.
7. Repeat steps 2 – 7 for remaining half of roof.
8. Apply putty /butyl tape to the backside of the roof-edge molding. Then while holding the bar, draw surplus material tight with a downward pull, but do not stretch the membrane. Drive screws through molding, membrane, and roof framing members. For best application install molding from center of unit to ends. Alternative method, staple membrane in place using ½” staples 3”-5” apart then apply bar. 9. If roof-edge moldings are not installed on roof during this time membrane will peel-up as drying.
10. Apply putty /butyl tape to the backside of the front and rear termination moldings/caps. Front cap will lay on top of the membrane, membrane should lay on top of the rear cap. Reinstall termination molding using screw type fastener, make sure to screw into sufficient roof structure to prevent lifting. Both edges of the front and rear roof molding must be sealed with caulk/sealant. A minimum 3/8” bead will work for most applications.
Openings & Vents and Appliance Installation
1. Using a utility knife “x” cut all roof openings. Make sure you round all 90-degree corners to eliminate the possibility of running cuts.
2. Surplus material must be secured by staples or screws inside the openings, trim all excess material.
3. Apply putty/butyl tape to all vents and accessories, when installing if any bubbles are noticed in membrane smooth bubble to vent opening and secure vent with screws.
4. Seal around all vents and accessories. Apply sealant to all visible screw heads. There is no need to spread the sealant as you are applying it. A minimum 3/8” bead will work for most applications.
*Butyl tape provides the “Primary Seal” against water infiltration or penetration in these membrane roof assemblies. The lap sealant is a secondary seal. Butyl tape must be compressed 30% to 40% to perform correctly.
Either side can be installed facing down. Some people think for better traction to install with the textured size facing up and the smooth side down toward the roof (facing glue), some people think for easier cleaning to install the smooth side facing up.
My roof turned pink!
This will happen when your roof is exposed to too much carbon dioxide, you leave the unit indoors or covered too long with no access to fresh air, once the unit is outside the pink will slowly disappear.
Why is the roof wrinkled around all the vents and skylights?
The solvents in the 1021 self-leveling sealant temporarily swell the roofing membrane. In the warmer months it takes 3-5 days to go away & 5-9 in the colder months.
Cleaning The Roof
Be sure to only clean each material with appropriate cleaning materials, we do not sell cleaning products.
