First Methodist Church Laconia, USA

Proven performance over time is perhaps the signature attribute of Sika roofing systems, which are also known for effective watertightness, energy efficiency and minimal environmental impact. This longevity under real-world conditions is proven around the world, for all construction types and in all types of climates. The roof of the First United Methodist Church in Gilford, NH (USA) has two unique features. The first is obvious – it has a very distinctive, sweeping shape known as the hyperbolic paraboloid. The second characteristic is not so apparent – installed in 1976, this roof was one of the very first Sika single-ply membrane installations in North America. It replaced a failing roof buildup that was only a few years old. The roof is still in place today, periodically maintained and in good condition.

Customer: First United Methodist Church in Gilford, New Hampshire (USA).

Project: One of the very first Sarnafil® single-ply membrane installations in North America, for a complex-shaped roof in Gilford, USA.

Requirements: The customer sought a long-lasting roof solution for a demanding structure.

Sika Solution: The 48 mil (1.2 mm) Sarnafil® G410 membrane was adhered to the plywood decking with Sarnacol® 2170 on the sloped roof area. On the flat roofs the 48 mil Sarnafil® G410 membrane was adhered by Sarnacol® 2170 to mechanically fastened 25 mm thick polyisocyanurate (PIR) thermal insulation.

Sika Sustainability Approach: The original roofing solution by the competition
lasted only 8 years. The alternative Sarnafil® G410 membrane was installed in 1976 (and in 1985 on the other part) and still serves to this day.
