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 length 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.
Local Pick-up Only can specify to have membrane rolled and not boxed, note this in the comment section during checkout.
PVC Membrane This is the newest Technology in RV roofing. It’s high level of strength, durability and resistance to UV rays, as well as chemicals, make it a natural choice for RV roofs.
PVC roofing systems not only reflect sunlight and solar energy, but they extend the useful life of the roof while helping to keep interiors cooler.
This membrane meets the high standards for RV roofing. Unlike stationary buildings, RV membranes must withstand extreme environments including subtle flexing and torsion of the chassis or frame during travel.
This product passed all the tests with flying colors. It has enough flexibility to work well in most any RV installation.

Membrane Ships Folded Depending on size of kit you will get one or two boxes (glue / membrane)

As soon as possible, while on top of clean unit remove membrane from box, do not drag over edge of unit.
·Do Not allow membrane to sit boxed for long periods, use as soon as possible.
·Do Not allow membrane to touch ground, dirty surfaces, sharp objects, or surfaces, including lifted screw head and edges.
·Do Not drag the membrane as this can cause punctures and tears, this is not covered under warranty.
·Membrane can be glued either side down. Single-Ply membranes are the same color throughout.
Membrane must be installed onto clean wooden surface, do not install on top of existing membrane, glue, etc.
·Router all vent and accessory openings. Sand all openings, seams, and edges to a smooth finish. Remove all debris off roof with air hose.
·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)
·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.
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 decking, brush can be used but is more difficult. (1 gal. will cover approximately 160-200 sq ft. best when applied in air temperatures over 50 deg F (10 deg C).
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) or linoleum roller; press firmly working from the center outward toward the edges, do not be on the roof during this time.
All wrinkles must be removed at this point for a quality installation. The roof will tighten and conform as the adhesive cures removing creases, be sure to complete roof securing steps before allowing roof to dry.
6.Repeat steps 2 – 5 for remaining half of roof.
Roof Securing Steps
7.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.
If roof-edge moldings are not installed on roof during this time membrane will peel-up as drying.
8.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.
Class A Customs Acrylic Water Based Adhesive is a technically advanced scientific formula of water base adhesive designed for use as a bonding adhesive for single ply roofing membranes.
Class A Customs Adhesive is a high solids adhesive with a short drying time. It is used in the Recreational Vehicle and Commercial Roofing industries to adhere membranes to wood decking (not designed for fiberglass).
It is ideal for applications where a quick dry time is dictated by production line speed or other variables.
Class A Customs Adhesive does not lose peel value over time, but remains flexible to allow for expansion and contraction of the membrane. When tested side-by-side with competitors RV adhesives, Class A Customs Adhesive was proven to be stronger and keep a better hold on both the rubber roofing, and the materials it was applied to.
Water Based Acrylic Adhesive Fast Setting - dries clear Bond grows stronger with age but remains flexible to allow for expansion and contraction of various roofing materials. Excellent adhesion to plywood, particleboard, MDF, and most roofing membranes such as EPDM, PVC, TPO, etc... Coverage 160-200 sq ft/gal
Best when applied in air temperatures over 50 deg F (10 deg C) For glue roller applicators and glue spreaders, can be hand applied by brush. Apply to one substrate with 10-12 mil coat weight to achieve excellent bond. To achieve best bond, apply to both substrates with 5-6 mil coat weight and allow to dry, then laminate to membrane and apply pressure with roller to insure 100% contact.
Diluent Water, if required. Use as received.
