Grace Ice And Water Shield Nail Laps High Pitch Roofs

Here s how proper installation of grace ice water shield the conventional method.

Grace ice and water shield nail laps high pitch roofs. I am about to reroof using grace ice and water shield for the first two courses then a synthetic underlayment above. Apply roof covering material at temperatures of 40 f 5 c or higher. Cut the membrane into 10 15 ft 3 5 m lengths and reroll loosely. Apply roof covering material at temperatures of 40 f 5 c or higher.

Grace ice water shield is used as an underlayment for sloped roofs to resist water penetration due to water back up behind ice dams or wind driven rain. Ice dams grace ice water shield should be used in conjunction. Grace ice water shield ht roofing membrane is used as an underlayment for sloped roofs to resist water penetration due to water back up behind ice dams or wind driven rain. The best defense against ice dams in cold climates is a so called cold roof consisting of high levels of ceiling insulation separated from the roof surface by a free flowing vent space see preventing ice dams page 97 in the printed text best.

Cut the membrane into 10 15 ft 3 5 m lengths and reroll loosely. If installed properly this reliable roofing underlayment can save homeowners 18 000 in reroofing costs. Press the membrane in place with heavy hand pressure. Tack secure the end of the roll with a nail.

Cut the membrane into 3 5 m 10 15 ft lengths and re roll loosely. Peel back 300 600 mm 1 2 ft of release liner align membrane. Grace ice water shield also offers leak protection in trouble prone spots like valleys skylights protrusions and other flashing areas. Grace ice water shield is designed to perform for the life of the roof covering.

End laps can be 4 to 6 and side laps in overlying courses lapped to either the 2 or 4 lay lines. Seals around nails the rubberised asphalt layer in grace ice water shield seals around roofing nails resisting leakage caused by water back up behind ice dams or from wind driven rain. Forms watertight seal at overlaps. Dual barrier protection rubberised asphalt and polyethylene are combined to form two waterproofing barriers providing maximum protection.

Eaves flashing recommendations for asphalt shingle roofs. Back nail the waterguard rain ice when a section of roof is covered use a heavy membrane roller over the entire surface to ensure complete adhesion. Peel back 1 2 ft 300 600 mm of release liner align the membrane and continue to peel the release liner from the membrane. Protects all standard sloped roofs slate tile shakes or metal as well as ordinary asphalt shingles.

Forms a watertight seal around fasteners used to install shingles and other roof coverings. Peel back 1 2 ft 300 600 mm of release liner align the membrane and continue to peel the release liner from the membrane. Roll overlap areas thoroughly.
