Asphalt Shingle – The Most Popular for Solar Energy

In New England, the most popular material used for homes and most other pitched roofing surfaces is the asphalt shingle, sometimes referred to as a composite shingle. These shingles have been used for decades and offer perhaps the greatest visual diversity which give home designers almost unlimited options.

Mounting Solar Panels on Asphalt Shingle Roofs

Homes and structures covered with asphalt shingles are typically pitched and not flat. The degree and style of roof pitch depends on the architectural effect targeted. Solar panel racking and mounting systems are designed with this in mind.

Southern Light Solar follows best practices both in selecting and installing solar panel mounting and racking hardware on shingle roofs. By designing with components from reputable and proven manufacturers such as IronRidge, among others, we are assuring our customers that years of experience is working for them.

More than choosing the best mounting hardware, a good installer must establish a dependable practice to install and fasten everything for years of reliable service.

  • Use effective techniques to locate rafters below the asphalt shingles and underlayment;
  • Follow roofing council guidelines that ensure anchor bolts are properly placed including drilling and creating pilot holes when needed;
  • Size and install flashing within each asphalt shingle manufacturers recommendations;
  • Use the highest integrity sealing materials and methods.

Benefits

Because of widespread and near universal use, asphalt shingles have the economic benefit over most any other choice:

  • Designed to have the best balance of initial cost and performance over the 15 to 20 year lifetime before replacement.
  • Comparatively unending range of styles – shapes, sizes, colors, and textures can all be modified.
  • Fit almost every standard roofing structure design. No need for additional support or structural revision.
  • Although not fully maintenance free, they are designed to be low maintenance and easy to repair by any reputable roofing contractor.

Adding Solar

Being the most traditional roof material, there is a large supply of suitable racking and solar panel mounting designs.

  • It is best to ensure an existing asphalt shingle roof will last 10 or more years before mounting a solar energy system on top.
  • Anchoring the solar energy system to the underlying roof support structure is mandatory.
  • The necessary anchoring penetrations are easily sealed using time-tested flashing methods or UV-resistant sealants.
  • Southern Light Solar uses extra caution to make sure the installation activities are gentle and avoid any potential damage to the shingles themselves and especially to the typical underlayment. This maintains the integrity of every roof’s water barrier over time.
