The primary purpose of a roof is to provide overhead protection against the elements. A roof protects the interior of a building from the rain, wind, snow and the sun. It would be easy to think that a roof is just a roof. That the same structure you put on top of your home would hold and have the same attributes as the structure over a commercial building. If you approached roofing contractors for a new installation they would want to know whether you wanted a residential or commercial installation. It is important to distinguish between the two because there are major differences in terms materials, structural design and cost. Let’s look at what makes commercial roofing by Armor Services different from residential roofing:
1. Structural Requirements
Commercial roofing has its own structural requirements that are different to those of residential roofs. For instance, a commercial roof may need to accommodate skylights, chimneys, ventilation systems, pipes and a plethora of other additions you would not need on a residential roof. The load capacity of commercial roofs is therefore higher than that of residential roofs.
2. Construction Specification
There are also construction specifications that are dictated by the type of activity happening within the commercial building. For instance, if you are building a roof of a commercial building where there is heavy use of machinery then the roof needs to be able to withstand the heat discharged by the machinery. Residential roofs are constructed to provide that overhead cover and protection, the most important consideration are durability, maintenance and appearance.
3. Design Specifications
The major factor that goes into designing a commercial roof is the size of the building it is meant to cover. Most commercial roofs are low sloped or flat. Flat roofs work well for commercial buildings because it is easier to install air condition units and ventilation systems. Flat roofs are cheaper and they are more practical for roofing that has to go over large buildings.
Design also takes into consideration the load capacities and all the additional features that the roof is supposed to support in addition to providing adequate protection from the elements and insulation. Commercial roofing is therefore designed to be robust, to withstand much more than a residential roof.
4. Material Specifications
Roofing materials for commercial buildings vary life expectancy, cost and application. Commercial roofing usually consists if a flat, metal or membrane roof. Residential roofs are steep and have more material options than the commercial kind. There are some materials that these two might have in common like Asphalt shingles, single-ply membranes or standing seam metal panel roofing.
5. Maintenance Requirements
The maintenance requirements for commercial roofing is different from that of residential roofing. Because of the low-slope, commercial roofs develop issues like water ponding, membrane punctures, seam separations, shrinkage, cracking, flashing around penetrations and other problems that do not develop for residential roofing. This is why commercial roofs need to be inspected and maintained to avoid problems.
When you are looking for a roofing contractor it is important to make sure that you choose someone who has the experience with commercial roofing. An experienced professional will know the ins and outs and all the other structural and design considerations that an inexperienced contractor might not be aware of.
