Replacing Your Commercial Flat Roof
When it’s time for your commercial roof replacement, a professional roofing service will give you the best results. An experienced roofer can design, install, maintain and repair your roof. As commercial roofs are typically large structures, flat roofs are preferable.
Flat Roof Systems
Flat roofs are easier than slant roofs to construct and maintain. They are long-lasting and durable. Some common types of commercial flat roofing materials include:
- EPDM Roofing
- White TPO Roofing
- Metal Roofing
- Torch Down Roofing
- Hot Tar Roofing
Replacing a Flat Roof
These roofing types require regular maintenance, but putting a new covering on a flat roof is much easier than on a slant roof. There are many ways to install a commercial roof replacement. Here is one method.
Removing the Old Roof
First, professionals will remove the old roofing and replace damaged surfaces underneath the membrane before installing the new roof.
Next, contractors remove the leftover nails to avoid ripping the roofing membrane’s felt. They will install wooden or synthetic cant strips next. These strips fill in the spaces that are not filled by felt.
Laying Down Base Sheets
After, they will lay down the base sheets. Paper, polyester or fiberglass base sheets typically have a two to four-inch seam. Once the sheets are in place, roofing nails spaced about eight inches apart fasten them to the roof.
Preventing Water Damage
Your installation professionals will then cut the base sheets to fit around vents and add flashings to avoid water damage. They will lay the first roll of roofing felt over the base sheet and add more layers with hot tar or asphalt.
Adhering the Roof
The roofers then apply asphalt with a large mop, one row at a time. They must keep the asphalt at the optimum temperature as they unroll the felt.
When your roof is leaking or in need of commercial roof replacement, consult a professional to determine the best methods and materials. A commercial roofing service will save you time and money while ensuring a long-lasting roof for your business.
