Product details

RoofTopGuard II is the newest technology in high-performance roofing underlayment. Recommended for use in place of standard underlayments such as 15 and 30-pound felt, RoofTopGuard II blows the competition away when it comes to performance and installer-friendliness.

High-Tech Protection – Hurricane Proven

As a contractor, you know all too well the problems of conventional roofing underlayments– they're prone to tearing and ripping, they're hot and heavy to work with, they're unpredictable in storms. They stick to metal roofing and tear with expansion and contraction. They can be dangerously slippery when wet. The list goes on and on, and add up to increased costs, worries and liabilities for you.

RoofTopGuard II is the high-tech, high-performance answer to these and other problems. Its 5-layer polypropylene/ polyethylene construction results in high strength, while maintaining low weight (under 43 pounds per roll) which makes it suitable for use under all roofing materials. Its 60" width and 10-square roll size speeds installation and minimizes seams so it installs faster, easier and is more secure.

Superior Foot Traction

RoofTopGuard II's exclusive "Fiber-grip" surface is slip resistant offering superior foot traction– independent laboratory tests show RoofTopGuard II has more friction and slip resistance than standard roofing felt, and other polymer-based underlayments can't match it for performance. Its excellent moisture barrier and wide-roll width reduces the need for ice and water protection. And, RoofTopGuard II contains no asphalt or asbestos– zero out-gassing.

Unmatched Product Performance

The bottom line? RoofTopGuard II meets or exceeds all national building code requirements, including Dade County, and consistently out-performs and out-tests conventional underlayments. In terms of product testing, our tests speak for themselves: for strength, elongation, UV resistance, watertightness and water vapor transmission, RoofTopGuard II consistently exceeds the standards.

Installation (no staples can be used)

VENTILATION: RoofTopGuard II must be installed above properly ventilated spaces (follow local building code) as it is considered a vapor barrier.

ROOF PITCH: RoofTopGuard II should not be used on slopes less than 2:12. [17% slope]

LAYING METHOD: RoofTopGuard II is laid horizontally (parallel) to the eave with the printed side up, and with 4" horizontal laps and 6" vertical laps. [The use of a slip sheet is not required underneath metal roofing]
Except in cases where Clay or Concrete tiles are to be installed. In those cases where the slope is from 2 ½:12 up to 4:12, the underlayment must be horizontally lapped a minimum of 30 inches [763 mm] to the center line of the underlying course to form a double layer with 6-inch [152 mm] vertical laps.

FASTENING METHOD: RoofTopGuard II must be attached to the structural Roof Deck Material using Plastic or Steel Cap roofing nails, having a minimum of 1" diameter cap, spaced at 12" on vertical and 14" on horizontal.
All Plastic, or Steel Caps, must be attached flush with the underlayment surface and nails must be fastened at a 90 degree angle to the deck. Follow the nailing pattern, which is marked by X's on the product.

BATTEN APPLICATION: For batten secured applications, the use of plastic cap roofing nails is required only to secure the underlayment and prevent blow off until the batten system is installed. DO NOT USE STAPLES TO SECURE BATTENS!

TILE INSTALLATION: For tile installations use a pressure sensitive, double sided tape such as MFM Double-Bond Tape acting as a self-sealing gasket or an SBS peel and stick foil faced tape, or a double sided tape approximately 2" in width, placed underneath the batten (parallel with the batten) to help seal any gaps between the underlayment and the battens or use the “Flow Through” batten system.

SEALANT: Where seams or joints require sealant or adhesive, use only a high quality, low solvent asbestos free plastic roofing cement meeting ASTM D-4586 Type 1 (Asbestos Free), Spec SS-153 Type 1 (Asbestos Free). In areas subject to wind-driven rain where the underlayment will be left exposed to the weather for an extended period of time, seal all seams with a butyl rubber, urethane, or EPDM based caulk or tape sealant.

SITE PROTECTION: Prior to loading the roofing materials onto the RoofTopGuard product, it is recommended that a roof jack, with planks, toe boards, or a strong platform be secured to the underlying roofing deck to prevent slippage of stored materials on steep sloped roofs (greater than 4 : 12 pitch). See OSHA regulations (Standard 29 CFR), fall protection systems criteria and practices – 1926.502.

FINAL INSTALLATION: Installing final roofing within 6 months from initial underlayment application is recommended.

The maximum allowable exposure of RoofTopGuard II when used as a Tile Roof Underlayment in FBC HVHZ jurisdictions is 30 days.
