Commercial Services Provided By San Jose Roofing Contractors

Commercial roofing services are different than residential services and there are many contractors out there that specialize in these, promising to ensure custom satisfaction.

Finding a San Jose roofing company and selecting the best one for your project is quite similar as in the case of selecting a residential contractor: building owners must look for licensed companies committed to respecting the state`s building codes and requirements, fully insured and willing to stand behind their work. However, the detail that should not be overlooked by prospective commercial clients is looking for a roofing contractor with commercial experience, because commercial roofing projects have their own particularities, involving different materials and techniques than residential roofing.

The difference between residential and commercial roofing

  • The design of the roof

Most commercial roofs are completely flat or with just a slight slope because this type of roof system is easier to be installed on large buildings without putting too much pressure on their structures.  In the same time, flat roofs require more maintenance services

  • The roofing material

Although there are roofing materials suitable for both residential and commercial project (asphalt shingles are probably the best example), some materials are typically used only in commercial buildings; they include modified bitumen and EPDM, which are resistant and cost effective for large buildings

  • The cost of roofing installation

Commercial roofing projects are typically more demanding than residential projects, due to larger roofing areas and structural challenges

  • Repairs

Different materials will require different repair techniques

The pros and cons of flat roofing

When it comes to commercial roofing projects, most contractors choose to build flat roofs that are basically formed by two components: a top coat and an under layer – both sealed together to become waterproof.

Flat roofs work great in California’s mild climate. Other advantages include:

  • If installed properly, they remain stable and provide good protection
  • They can be easily climbed and inspected
  • They do not negatively affect the overall aspect of a building
  • The installation costs are affordable and re-coating is also cheaper than in the case of other sloped roofs

As about the disadvantages, first of all, we must mention that flat roofs require periodical intensive maintenance, otherwise they will lose their integrity and efficiency sooner than other roof systems. A maintenance program for commercial buildings should always be performed by San Jose roofing contractors  and include inspection and documentation, free estimates and the maintenance operations (cleaning, reconditioning, small repairs, prevention etc.)

Also, it is essential that the roofing company takes all the necessary measurements before the installation in order to determine if the covered area will allow the roof to remain stable in any circumstance. If the weight of the roof is not properly supported, it must be compensated with interior structural support.

Flat roofing materials

  • Modified bitumen – cost effective, energy saving and aesthetically pleasing
  • Synthetic rubber (EPDM) – very durable
  • PVC – easy to install and very efficient
  • Silicone – sustainable and applicable on top of other substrates
