PROTECT AND ENHANCE YOUR HOME WITH VINYL AND POLYMER SIDING
While your roof protects your home from the elements, the exterior walls also play a key role in shielding your home and typically do so through the use of siding. The number of siding choices and materials have advanced beyond just aluminum siding with a growing variety of affordable vinyl and polymer siding options for every house.
Siding’s job is to shed water, protect the walls and in some cases insulate your home. Because of the many types and wide variety of colors and styles, siding matters in the aesthetic appeal of your home.

At Greenawalt Roofing, we recommend and install CertainTeed siding products. The company offers vertical siding, horizontal siding, shake and shingle siding for the look of shake without the maintenance and even insulated siding with the look of natural wood that can help reduce your heating and cooling bills.
We know that choosing a siding style and color can be challenging so we are happy to assist you in selecting the right look for your home. CertainTeed also offers online design tools that allow you to see what different colors and styles look like on different homes.

What Central Pennsylvania property owners should consider
SIDING INSTALLATION is best understood in the context of the whole property, not from one symptom alone. The age of the materials, previous repairs, water-management details, installation methods, and nearby exterior components can all affect what is visible. Central Pennsylvania’s mix of heavy rain, wind, summer heat, falling leaves, freeze-thaw cycles, and winter weather can also make the same concern look different from one home or building to another.
Start with observations that can be made safely. Avoid climbing onto the roof or disturbing damaged materials. Instead, note when the concern appeared, whether it changes during particular weather, and whether it is isolated or occurring in several areas. Photographs taken from a safe location and notes about prior work can help a professional understand the history without relying on memory alone.
Details worth documenting
- open seams, failed trim, or areas where water may enter
- fading or mismatched repairs that affect the project scope
- signs that the concern may extend behind the visible siding
- cracked, loose, warped, or missing panels
- staining or softness around windows, doors, and penetrations
These details do not replace an on-site evaluation, but they make the conversation more useful. They also help separate a maintenance item from a repair need or a larger project. A clear evaluation should explain the observed condition, the likely scope, the surrounding components that were checked, and any assumptions that could affect the recommendation.
Questions to ask before authorizing work
- Can the affected area be repaired cleanly, or is replacement more practical?
- Is there evidence of moisture behind the visible surface?
- How will trim, flashing, and penetrations be handled?
- Can the existing profile and color be matched?
- What ventilation or drainage details are part of the wall system?
- How will nearby roofing, gutters, windows, and doors be protected?
Ask for the proposed work in writing and compare scopes rather than price alone. Materials, labor, disposal, cleanup, ventilation, flashing, permits, warranties, and possible concealed conditions should be easy to identify. If alternatives are available, the practical differences should be explained in plain language so the decision reflects the property’s needs and the owner’s priorities.
