The basic differences in a flat over an angled covering in commercial repair is one of preference. Both will require timely maintenance. For flat surfaces that are smooth, it will require cleaning in preparation for repair. If there is wet insulation under the membrane, it will need to be removed and replaced. If there is damage to the beams or structure it is fixed at this time. Afterwards, a new surface is installed, there needs to be a total replacement. If there are only certain areas that are needing attention, it will be done by cutting out the old and replacing it with new layers and coating. Elastomeric coatings are used for the superior expansion characteristics that are desired in climates with extremes in temperature. All in all, commercial repair for a flat surface is done similar to any other flat roof that is not a commercial roof. Our website provides info about commercial roof repair
Taking a look at some repair materials for an angled exterior surface, we find that so many are used that it is not possible to mention them all. Some are metal coatings, canvas, recycled materials, gravel foam systems, mansard, single-ply, standing seam, and others. Metal is a popular choice. The TPO system is another popular choice and is made of a thermoplastic, reinforced fabric, and rubber together. All the commercial roof repair projects on these are going to need different tools and expertise. The metal covering is corrugated to fit together and channel the rain downward. The repair on this is sometimes just a simple coating. For more extensive repair, sheets may be removed and replaced.
The TPO commercial roof repair is dependent on the age of the surface. A TPO covering has membranes that age under the stress of sun wind and rain. They are repaired using a heat welding process. It is quite simple. What happens is that you scuff up the surface, prime it with primer and then use a sealant to replace old material with the new.
As easy at is sounds, commercial roof repair is still a big job, covering what sometimes can be acres of area. Dealing with large numbers is a basic difference between commercial roof repair and residential home repair. Different materials are used because the aesthetic value of a commercial roof is less than a residential one. All in all, commercial roof repair is simply an ongoing task every business should be ready for.
