Commercial Roofs include: TPO,EPDM, PVC, Various Modified Bitumen roofs including “Hot Tar” and coating systems, Metal, Tile and Asphalt Shingles.
Commercial roofing covers a lot of ground, but whatever system you choose make sure it is one that suits your needs for insulation, fire rating, insurance approval, energy efficiency and possible LEED credits. We will also work with engineers to custom tailor a commercial roof system that fits all of your needs. We install almost all low slope roofing systems including: single-ply TPO, EPDM and PVC
(Mechanically fastened and fully adhered), built-up roofing, modified, polyurethane foam with coating, and stand-alone roof system coatings.
Maintenance and Inspection
Remember the saying an ounce of prevention is worth a pound of cure. Nowhere is that saying truer than in commercial roofing .If you don’t have a maintenance and inspection plan in place for your commercial roof you could be costing yourself loads of cash that may have been prevented for very minimal costs. Call us and set up a consultation. We would be glad to customize a maintenance and inspection system for your roof.
Nothing ruins a day more than someone getting hurt on the job. Although accidents are a fact of life, we’ve minimized the risk of them happening by implementing a complete safety system according to OSHA 1926 standards for the construction industry.
Insulation is one of the most important factors on a low slope roofing system. Insulation can be tapered and have a slope to assist with drainage and have a significant impact on your buildings energy consumption, not to mention the stress on your HVAC systems. Some types of roof insulation systems are: ISO Board, Dens Deck, EPS, and Fiberboard.
Ventilation is probably the most overlooked element by building managers and roofers alike. However, this small detail can greatly improve the life of a roof. Should the roof system fail and have a small leak, there is a way for that moisture to escape as quickly as possible. It also prevents large bubbles particularly in built-up roofing. Ventilation is how your roof breathes in the hot and cold months and allows moisture to escape preventing mold in humid climates. Let us design a roof ventilation system that is right for your building and the roofing system you’re using.
It is imperative that every low slope roof has adequate drainage in the form of a slight roof or insulation slope, drains, or scuppers. There should not be any ponding water on a low slope roof 48 hours after a rain. If there is then your roof is very susceptible to failing earlier than expected. This also leaves room for algae to grow and even foliage on top of your roof. A ¼” slope is recommended for every linear foot of roof to perform positive drainage that meets most manufacturers’ specifications.
Installing a “cool roof” system can not only prolong the life of the roof, but can save a tremendous amount of money in cooling costs and HVAC wear and tear. In short, a cool roof system refers to an energy efficient roof. A cool roof reflects and emits the sun’s heat back to the sky instead of transferring it to the building below. “Coolness” is measured by two properties, solar reflectance and thermal emittance. Both properties are measured from 0 to 1 and the higher the value, the “cooler” the roof. Read More
The Cool Roof Rating Council (CRRC) is an independent, non-profit organization that maintains a third-party rating system for radiative properties of roof surfacing materials.
TPO is now the leading commercial roofing system of choice. It is available in white which qualifies as a “cool roof” making it an energy efficient roof system and possible candidate for LEED credits from the U.S. Green Building Council (USGBC). It is also one of the most affordable roofing systems on the market. Standard thicknesses are 45, 60 and 80 mil with 60 being the most popular because of balance between cost and protection.
PVC roofing is better than TPO for restaurants because of its ability to stand up to grease coming off the ventilation system. PVC also comes in “cool roof” colors.
Sprayed Polyurethane Foam with an elastomeric coating system is also becoming a very popular system because of the technology of “closed cell” foam with a coating system, making this a seamless “cool roof” system. Combined with a very economical cost factor, this is a system that is hard to beat and is being looked at more and more by building owners and managers.
A built-up-roof is composed of alternate layers of bitumen and reinforced fabric or felt usually with a base sheet on the bottom and a mineral surfaced cap sheet at the top to build a finished membrane. The number of plies that cross in a section is the number of plies on the roof. Most built up roofs are 3 or 4 ply. Built up roofs can be built with hot asphalt or coal tar that is heated up in a kettle, or cold process solvent based asphalt adhesives.
Modified bitumen roof system membranes are composed of multiple layers, much like BUR membranes.
There are two types of Modified Bitumen roofing membranes:
- SBS polymer-modified bitumen membranes commonly are installed in hot mopping of asphalt (similar to BUR systems) or cold adhesive. Some SBS modified membranes are self-adhering; that is, they contain an adhesive backing.
- APP polymer-modified bitumen membranes typically are heat-welded or torch-applied. Consumers should be cautioned that NRCA does not recommend torch-applying a modified bitumen membrane sheet directly to a wood deck.
