Your trusted partner in historic preservation and landmark restoration
Historic preservation presents complex challenges. Landmark buildings must be protected from environmental exposure, aging materials, and evolving performance demands. From civic institutions and museums to heritage sites and historic roofs, each of these structures represents a responsibility beyond function.
At Siplast, our high-performance roofing, waterproofing, and building enclosure systems are designed to help protect original systems and assemblies without sacrificing the character or integrity of the building’s exterior. Our high level of collaboration helps design professionals, contractors, and owners navigate complex detailing, phased construction, and preservation standards with confidence.

Frequently asked questions
High-performance roofing materials that can provide impact resistance, such as Siplast SBS-modified bitumen membranes and Paratherm NH polyiso insulation, can help mitigate the risk of water infiltration and structural damage, while helping to ensure the preservation of the site's architectural heritage.
Energy-efficient roofing systems can help reduce operational costs by utilizing highly reflective roof membranes, like Siplast Parasolo TPX and SBS-modified bitumen sheets with light-colored surface options, and advanced insulation can help lower the demand on HVAC systems to potentially lower cooling costs.* By stabilizing indoor temperatures and managing moisture, these systems can help prevent thermal expansion and contraction that can lead to cracks and structural fatigue. This approach helps historic sites meet modern performance standards while maintaining their original architectural character.
Durable and dependable roofing systems help reduce the frequency of roof replacements, which helps minimize the risk of exposing vulnerable historic interiors to the elements during construction. By investing in a high-quality roofing solution, like Siplast SBS-modified bitumen or PMMA liquid-applied systems, conservators can ensure the building’s integrity is maintained.
Siplast uses PMMA liquid-applied waterproofing to create a seamless layer that conforms to the irregular geometries and intricate transitions common in historic structures. This flame-free application provides a monolithic bond that bridges varying materials without the need for mechanical fasteners. By integrating PMMA resins with traditional membrane systems, Siplast can ensure that irregular architectural details remain watertight without compromising the building's original aesthetic or structural integrity.
