There are a ton of factors you must bear in mind when deciding on the appropriate insulating material. It should abide by existing energy codes, before anything else. It ought to likewise meet the requirements of your property insurance carrier and, of course, be well-suited to your house's roof design.

A sensible choice of insulating material results in an efficient and durable roofing system. A substandard choice leads to unsatisfactory roof performance, which becomes easily apparent a very short time after installation. Thankfully, Federal Way and Des Moines roofing experts can help you make the first one.

It is essential to understand which roof insulation material goes (or does not go) with specific kinds of roof covering. For instance, polystyrene must not be placed in direct contact with thermoplastic PVC single-ply membranes. Doing so leads to plasticizer migration, which makes the PVC membrane brittle. Likewise, standard built-up, as well as modified bitumen membranes, ought to not be directly used over foam plastic insulation boards. Cover board insulation is instead recommended for these roofing materials.

One more consideration is whether a specific insulation material is approved for a particular roof deck kind. Building codes allow, for instance, the direct application of polyisocyanurate and polystyrene over steel roof decks—as long as the manufacturer of the material has tried out and passed the needed tests. Certain remedial procedures, though, may be undertaken if the roof insulation product has not passed the necessary tests. In the instance above, a thermal barrier (such as perlite or gypsum), may be put underneath the foam plastic insulation.

Insurance company requirements must also be considered when choosing a roof insulation material. A lot of properties in Washington and across the United States are insured by an FM Global affiliate or a company that calls for FM Global-approved roof assemblies. Such approvals are really particular concerning the kind, manufacturer, and configuration of the roof insulation material.

The importance of getting an insulation product that works with the design of your roof system and meets many other requirements cannot be focused on enough. It may appear like an overwhelming task, but, thankfully, trusted Des Moines and Federal Way WA roofing professionals are always eager to provide assistance.
