Denver’s Green Roofing Ordinance for Commercial and Multi-Family Roofing

Denver’s Green Roofing Ordinance for Commercial and Multi-Family Roofing If you are thinking about replacing your commercial or multi-family roof in the City of Denver, then here are 5 things you must know to make sure your roof is compliant with Denver’s new Green Building Ordinance! 1. Minimum Requirements: If your building’s total square footage is over 25,000 sf, then the roof replacement request must go through Denver’s Green Building Ordinance review. There are a few exceptions, but for the most part buildings over 25,000 sf will be subject to review. The review for a Green Roofing permit is a much longer process than pulling a traditional roofing permit for a single-family residence and your commercial or multi-family roofing permit could take up to a few weeks or longer for review and approval.  2. “Cool Roof”: One of the main requirements for Denver’s Green Building Ordinance is to install a “cool roof” system.  a. For flat commercial roofs, the roof must meet “cool roof” requirements, such as a highly reflective membrane, appropriate insulation, and air/moisture barrier. The membrane could be TPO (Thermoplastic Polyolefin) or white EPDM (Ethylene Propylene Diene Terpolymer). If you are getting estimates to replace your roofing system, ensure the estimate includes the above requirements for a “cool roof” in Denver.  b. For steep-sloped roofs, be careful as Denver may require the use of “Cool Roof” shingles. If that’s the case, the costs for a “Cool Roof” shingle system are dramatically more expensive than traditional shingles and the lead time to have them delivered to Colorado could be weeks to months.

Compliance Options: Additionally, on top of the “cool roof” system, Denver may require you to meet one of the following compliance options: a. Green Roofs / Green Space: Very expensive! b. Installing on Site or Purchasing Off-site Solar or other renewable energy: Very Expensive! c. Energy Cost Savings: Cost-Effective! d. Green Building Certifications: Cost-Effective!

Snow on the Roof: What You Need to Know About Colorado Heavy Snow

Snow on your roof is not always the worst thing. There are some advantages to having a light layer of snow on top of your home, but you should be aware of the possible dangers and how to avoid them.  Advantages of Snow on the Roof  Snowflakes gathered on top of each other form air pockets causing sound to become muffled. As a result, you experience a sense of quite calm. A layer of snow can act as a form of insulation, protecting your home from losing heat. How quickly snow melts can be an indication of whether you are losing heat through your roof. If you have gaps and cracks in your roof, warm air will rise and escape, causing the snow to melt quicker than conditions should allow.     Problems with Heavy Snow on the Roof  However, different roofs are designed and manufactured to handle different weight loads. Too much ice and snow accumulations on your home’s roof can put it at risk of collapse. Colorado’s wet, heavy spring snows can cause considerable pressure. Heavy snow, poor roof drainage combined with poor construction can reduce your roofs’ integrity. Over-stressed roofs will begin to creak, leak, and cause ceiling sagging. Do not delay in contacting NexGen Roofing if you see or hear any these tell-tale signs.    What to do After a Heavy Snowstorm  Colorado’s snow loads plus freeze-thaw cycles can exaggerate existing roof problems. It is a good idea to have your roof inspected for loose, unsecured roof flashing, dislodged shingles, and open gutter seams where caulk has been broken.   Roof damage can be expensive to fix. Heavy snow accumulation on your roof can lead to severe water damage, which can lead to costly roof repairs. Unfortunately, not doing routine maintenance on your roof can void warranties and homeowner's insurance will not cover repairs and maintenance.   Your roof IS your home’s first line of defense against severe weather. Having a roof protection plan can help you avoid costly repairs, leaks and other problems related to roof damage.   NexGen Roofing’s Peak Protection Plan offers low-cost roof protection, starts with a FREE 25 Point Roof Check-up that gives you piece of mind after a snowstorm.     Watch the video to learn more about our roof protection plan.
