Long-Term Energy Savings

The MR-24 roof, combined with 2, 4, 6 or more inches of fiberglass insulation stops the energy lost through an old, badly deteriorated built-up roof system. Butler provides a total roof system. We know that very few roofs are free of obstructions. And often those obstructions can create places where water can leak in and energy can leak out. Butler provides more pre-designed solutions for roof conditions because we know your roof must act as a total system. You don’t just want panels, clips and flashings – you want a complete roof system that’s weather tight. No matter how many penetrations and problems your current roof has, the MR-24 roof system can give you weathertight security and save long term energy and maintenance costs for years to come.
