Commercial Built Up Roof

A built-up roof consists of layers of reinforcing material (organic felts, fiberglass mats or polyester), inter-ply layers of bitumen (asphalt or coal tar) and a finish surfacing, such as mineral surface cap sheets, or coatings.

The repetitiveness of a built-up roofing system — its layer upon layer nature — provides both flexibility and durability. The number of plies and the materials used for surfacing can be varied to adapt the system to virtually any environmental or aesthetic concerns. For the same reason, a built-up roof is more durable than are many other roofing systems under harsh heating conditions of a Houston Summer.

In today’s money-conscience society, built up roofs for commercial buildings have become the choice for its impressive impact in lowering costly utility bills and overall heating and cooling costs.

What is a Built Up Roof?

Commercial Built Up Roof come in two basic types, asphalt and coal tar, and three basic components:

  1. the waterproofing component
  2. the reinforcing componentcommercial-built-up-roofer-houston
  3. the surfacing component which is used to protect the other components from the elements

The roofing membrane is protected from the elements by a surfacing layer, either a cap sheet or gravel embedded in bitumen or a highly reflective coating material. The most common surface for a built up roof system, is a fiberglass mineral surfaced cap sheet. It offers a number of advantages. It has a white granular look, it is cost effective, and is relatively maintenance free.

Are Built Up Multi-ply Roofs energy-efficient?

Thermal Performance

Built-up roofing systems exhibit exceptional resistance to the conduction of heat between the exterior and interior commercial built up roof houston Texas, commercial built up roof system houston Texas, commercial built up roof systems houston Texas, commercial built up roofs houston Texas, of a building, resulting in noticeable reductions in heating and cooling costs.

  • Built up roof systems incorporates the roofing insulation into the monolithic roofing membrane and results in better insulation or a higher R value for better thermal performance your roofing system can achieve.
  • built up roof systems may have a ballast layer added to them (local building code permitting) which can increase the thermal performance. (Need Better Language from the SPRI report Andre Wrote on ballasted systems)
  • A built up roof system generally incorporates insulation in the design of the roofing system because of the multiple layers increasing the insulation properties that can boost the energy efficiency of the system.

How do Built Up Multi-ply roofs provide added protection?

Fire and Uplift Resistance

Built-up roofing systems are tested through Underwriters Laboratories and Factory Mutual Research Corporation to meet very strict fire resistance requirements and ensure adequate uplift resistance under extreme wind conditions.

  • Uplift: The built up roof systems continuously adheres each layer to one another forming a monolithic structure with out the need for fasteners. This monolithic layering reduces the number of penetrations and stress points caused by fasteners and increases wind resistance.
  • Fire Resistance: FM1 include the highest fire rating available. UL Class A is the best in the industry.

Can an Commercial Built Up Roof be used to meet cool roofing standards and meet Energy Star program requirements?

Yes, multiple options exist to make a black Built Up Roof into a highly reflective or “cool” Built Up Roof:

  • A commercial built up roof can be coated commercial built up roof houston Texas, commercial built up roof system houston Texas, commercial built up roof systems houston Texas, commercial built up roofs houston Texas, with UV reflective material to become a more highly reflective “cool” roof. This is typically done with an aluminum coating to increase the surface reflectivity. A highly reflective white coating can be used but special precautions must be taken to ensure the white coating does not yellow over time due to a phenomenon called bleed-through.
  • Commercial built up roof systems can be covered with a white granulated cap sheet to meet cool roofing requirements.
  • Ballast may be added—-DETAILS WHY considered cool.

Is a multi-ply Commercial Built Up Roof System economical?

Compared to other high performance commercial roofing systems, built-up roofing is one of the best investments on the market today due to its competitive cost per year of expected service life.

  • Low maintenance: Recommended annual inspection to check for clogged drains, gutters, pitch pockets needing to be tipped off, damage caused by a service repairman, etc.
  • A multi-ply smooth surface built up roof system can be restored by resurfacing a flood coat of asphalt, a fibered aluminum roof coating, a white or pigmented elastomeric roof coating, and/or asphalt coating and gravel.
  • Multiple-ply means fewer headaches, when using the roof as a platform for your vegetative roof, solar array or outdoor living space. The multiple ply provide added protection so there’s no need for expensive deconstruction of items inhabitation the roof to affect repairs like single-plys.
