Flat roofs are becoming an increasingly popular choice for your commercial property, and in some cases, your home. They are a flexible alternative to asphalt shingles or metal roofs because they can provide heavy loads of material. This is particularly helpful for Minnesota winters where large snow falls accumulate week after week. There are many people in the Denver Colorado area looking for a company that would help them choose the proper roof covering, and that is what Twin City Roofing is here to do.
Benefits of a flat roof
There are many advantages when it comes to building a flat roof. This is one of the most cost-effective methods of roofing alternative due to the fact that it allows the full height of the rooms below to be utilized and it reduces the quantity of required material for roofing.
Flat roofs, depending on the system selected, are “green” roofs, and can meet Energy Star performance levels, making your roofing system an all-around environmental friendly selection. This can save you money in the heating and cooling department.
Flat roofs are also considered low maintenance. Because there are no slopes or valleys, they are easier to clean and maintain than a pitched roof.
Flat roofs also provide the option for recreational or decorative finishes not available with a pitched roof.
Flat roofs are also convenient for installing large HVAC equipment that otherwise would have to be installed on the ground.
Disadvantages of a flat roof
The primary disadvantage to a flat roof relates to drainage or lack thereof. A flat roof can be designed to drain water moderately well. The more pronounced drainage problem occurs during winter, when snow sits until it melts. However, Minnesota code requires a ¼” slope per foot to ensure proper draining and to prevent ponding. This is called tapered insulation.
Modern technology has addressed this problem and today a rubber membrane can be added to the roof that should stop leaks instantly.
A flat roof can require repairs sooner than its sloped counterpart, however, it is still going to be considerably cheaper as an overall system.
The three most popular flat roof systems that we install are EPDM, TPO and Duro-last.
EPDM has superior resistance to hail damage for up to 2” hail
It will not become brittle and shatter due to low temperature flexibility
EPDM is installed from Minnesota to Texas, showing the extreme temperature fluctuation that it is resistant to
Due to excellent UV resistance, EPDM materials can be warrantied for up to 30 years
EPDM was originally designed for pond linings, so compared to many other flat roofing systems, it has superior water resistance and is not affected by pooling or standing water
TPO systems are often the cheapest flat roofing system and are often widely chosen on this fact
TPO is a white covering and is also an attractive choice for energy and environmental reasons
The system comes in smaller rolls which are attached to the roof and to each other
TPO can be attached mechanically (screwed) or fully adhered (glued) depending on the size of the roof and budget
The system offers varying thicknesses depending on the nature of the project
TPO roofs can have some problems with high exposure to UV rays
Every Duro-Last roof is manufactured to exact size in a controlled factory environment. This eliminates a large portion of rooftop installation seaming and ensures an excellent fit.
The Duro-Last roofing system is resistant to fire, chemicals, grease, high winds, and punctures, and easily accommodates wide temperature extremes.
Duro-Last protects the commercial and industrial building owner with either a 15-year full warranty or a 20-year prorated warranty.
Duro-Last offers a white membrane that qualifies for an Energy Star rating as well as black and our popular rock pattern, ideal for surfaces that will be visible.
DecTec is a great solution for trafficked areas. It can be used directly over living areas and is ideal for sundecks, patios, balconies, roof decks, boathouses, and garage decks.
100% expansion factor allows for expansion and shrinking caused by the variable elements of weather and the element of lumber drying.
A PVC membrane reinforced and coated to a polyester fabric mat through a spread-coating process provides durability plus UV, mildew and salt resistance.
Minimal maintenance combined with proven longevity equals low life-cycle costs based on a “per year” expense when compared to alternate walkable roofing options.
