Built Up Roofs
Once the traditional approach to flat roofing in America, Built-Up Roofing
Systems are enjoying renewed popularity due to significant improvements in
materials, design and application techniques.
Key Feature
- Durability. The strength of today’s composite, built-up
roofing systems make them resistant to puncturing and general rooftop
abuse. They are often a great choice for roofs that see a great deal
of traffic.
Additional Features
- Good life expectancy (15-25 years) if properly maintained
- Easy to
maintain and service
- Reliable
- Can be completed without a final coat of gravel for projects requiring
a finished surface that is both
smooth and ultraviolet light-reflective
Limitations
- Limited ability to handle expansion and contraction requiring
the installation of expansion joints
- Ponding water can shorten the
roof’s effective service
life
- Can emit an offensive odor during the installation process
- Caution
required during installation due to the need for an open flame
- More
maintenance is generally required
