Although Built-Up Roofing Systems (BUR) and Modified Rubber Roofing Systems are often used commercially, these types of roofs can also be used effectively for residential homes.
BUR roofing systems are the most popular and conventional roofs on the market today. There are several different types of BUR roofing systems available for installation:
All BUR systems are "built up" using hot asphalt. They are still the most popular roofing systems, and the most cost-effective. With the introduction of Title 24, some of the BUR Systems are approaching the same pricing as the Single Ply Systems. The biggest drawback to the BUR Systems is the smell of hot asphalt and the noise of the kettle.
Modified Bitumen Rubber Roofing Systems are applied with a hand-held torch. On larger jobs, a "dragon wagon" is used. This is a 3-foot-wide machine pulled by one technician. Modified rubber is similar to single ply as they both consist of one layer of waterproofing. All drains, metal, and flashing get an extra layer of modified rubber. This is what we in the roofing industry call "sandwiching the metal."
The application of a Modified Bitumen Roof is more convenient than the application for BUR systems, since a kettle and hot asphalt are not needed, and the pricing is comparable to that of the higher-end BUR Systems.
I was very happy with Midwest Roofing's work. We had scheduled a different company, but when the season got busy they stopped returning our calls. This never happened with Midwest. They maintain good communication, and all of our calls were returned promptly. They were extremely competitive on the pricing. Mark was the supervisor, and he handled everything perfectly . . .
