Understanding Roofing Underlayment and Why ProArmor® from Owens Corning Takes the Lead
Admin • September 20, 2019
You’ve probably heard about covering, sheathing, flashing, and other elements that make up a roof system a dozen times before. But what both contractors and consumers often fail to pay heed to is underlayment. Well, they shouldn’t. Just because it is an extra part of that complex structure does not make it of no significance. Underlayment protects your deck from water penetration, thereby preventing attic leaks and mold growth. Isn’t that important? We think it really is.
Simply put, underlayment is an added line of defense against the elements. To better understand what it serves as, think of your roof system as a sandwich, in which the first slice of bread is its deck while the second one stands for shingles. Underlayment is installed right in between, providing additional protection against leakage and structural damages.
Although applying it onto the deck is not a must, roof underlayment is necessary for low-slope building coverings. The thing is that the risk of leaks with these roofs is higher than with steep-slope ones because rainwater drains too slowly. However, it’s not uncommon to install underlayment even on steep slopes for better insulation.
Which type of underlayment protects your property most effectively?
With all the advancements in modern roofing technologies, 3 types of underlayment are considered most popular these days. Here’s a closer look at each of them:
- Felt underlayment. It is a traditional and least expensive type known as #15 or #30 (depending on the thickness option). As its name implies, it is made from asphalt-saturated felt that may be reinforced with fiberglass. What you must know is that this underlayment does provide some water resistance, yet it’s not waterproof.
- Rubberized asphalt membrane. Made from rubber-like materials, this type is one of the best in terms of sealing properties and the easiness of roof underlayment installation. It is flexible, non-skid, and designed to stand up to UV rays. Its heat resistance qualities are second-to-none, too.
- Synthetic underlayment. If you’re in the market for a waterproof barrier that is light, yet as durable as brick, you now know what to go for. The membranes of this type rely on polypropylene or polyethylene to ensure effective insulation, and they are the longest-lasting solutions. Of all them, ProArmor® synthetic underlayment is definitely one that stands out.

A well-built deck creates an inviting outdoor living space that adds value, functionality, and curb appeal to your home. If you're looking for a durable, low-maintenance alternative to traditional wood, TimberTech composite decking is an excellent choice. Designed to resist moisture, fading, staining, and splintering, TimberTech products provide the appearance of natural wood with significantly less upkeep. This guide walks through the major stages of building a TimberTech deck, from planning to the final inspection. Home Run is an official TimberTech Gold installer with specialized TimberTech training and access to enhanced warranties. Planning the Project Every successful deck begins with careful planning. Determine how the deck will be used, whether for entertaining, outdoor dining, or simply relaxing. Consider the size, shape, and location of the deck while taking into account access points from your home and the surrounding landscape. Select the TimberTech decking collection and color that best complements your home's exterior. At this stage, establish a realistic budget that includes materials, hardware, permits, and any specialized tools you may need. Before construction begins, verify local building codes and obtain any required permits. Preparing the Site Once the design is complete, prepare the building site by clearing vegetation, removing obstacles, and marking the deck layout with stakes and string lines. Confirm that the area is level and that drainage directs water away from the home's foundation. Accurate measurements during site preparation help ensure the framing and decking install smoothly later in the project. Building a Strong Foundation The strength of any deck depends on its foundation. Install concrete footings below the local frost line according to building code requirements. Secure support posts to the footings before installing beams and floor joists. Carefully check that all framing members are square, level, and properly spaced. Solid framing provides the support needed for the composite decking and helps prevent movement over time. Installing TimberTech Deck Boards With the framing complete, begin installing the TimberTech deck boards according to the manufacturer's recommendations. Many TimberTech products use hidden fastener systems that create a clean, fastener-free surface while maintaining consistent spacing between boards. Work methodically across the deck, checking alignment frequently. If your design includes a picture-frame border or decorative patterns, install those features as you progress. Take extra care when constructing stairs to ensure uniform rise, run, and secure fastening. Installing Railings Railings enhance both safety and appearance. Install railing posts securely to the deck framing before attaching the top and bottom rails. Complete the system by installing balusters and any gates required for stairways or access points. Choose railing styles and colors that complement your decking for a cohesive finished look. Adding the Finishing Touches Complete the project by installing fascia boards to conceal the framing and create a polished appearance. Many homeowners also choose to add deck lighting, post cap lights, stair lighting, or under-rail illumination to improve safety and extend the enjoyment of the deck into the evening. After construction is complete, clean the deck surface and remove any remaining debris. Final Inspection Before putting the deck into regular use, perform a thorough inspection. Verify that all fasteners are secure, railings are solid, stairs are stable, and the structure complies with applicable building codes. A careful final inspection helps ensure the deck is safe, attractive, and built to last. Maintaining Your TimberTech Deck One of the biggest advantages of TimberTech decking is its minimal maintenance requirements. Unlike traditional wood, composite decking does not require annual sanding, staining, or sealing. Routine maintenance typically includes: Sweeping away leaves and debris. Washing the deck periodically with mild soap and water. Cleaning spills promptly to prevent staining. Inspecting railings and fasteners during seasonal maintenance. With proper care, a TimberTech deck can maintain its appearance for many years while requiring significantly less maintenance than a wood deck. Conclusion Building a TimberTech deck is an investment that enhances both your home and your outdoor lifestyle. By carefully planning the project, constructing a solid foundation, following proper installation techniques, and performing regular maintenance, you can create an outdoor space that is beautiful, durable, and enjoyable for years to come. Whether you're building the deck yourself or hiring a professional contractor, choosing quality materials and following best practices will help ensure a successful project and lasting results.

How often to clean gutters depends on your trees, climate, and gutter type. Louisville homeowners guide — schedules, signs, and when to call a pro.
Metal roofing has gone from a niche product to one of the most talked-about options in residential roofing over the last decade. You've probably seen it on newer builds, heard it mentioned by a neighbor, or come across it while researching a roof replacement. And then you ran into the price tag. That sticker shock is usually where the research stops — or where homeowners start looking for reasons to justify it. This guide doesn't do either. It gives you the honest metal roofing pros and cons and a clear framework for deciding whether it makes sense for your specific home in Louisville. What Is Metal Roofing? Before getting into pros and cons, it helps to understand that "metal roofing" covers several different products that perform and cost very differently. The two most relevant for residential homes in Louisville: Standing seam metal roofing — panels run vertically from ridge to eave with raised seams that interlock. No exposed fasteners. This is the premium option you see on high-end custom homes. It's what most people picture when they hear "metal roof." Metal shingles / stone-coated steel — metal panels shaped and coated to look like traditional shingles or tiles. Lower profile than standing seam, easier to retrofit, and less expensive. There's also corrugated metal — the classic ribbed panels more common on agricultural buildings and outbuildings. You'll occasionally see it on residential homes for a specific aesthetic, but it's not what most Louisville homeowners are evaluating. Standing Seam vs. Corrugated Metal Roof Since both come up in residential conversations, here's a direct comparison:
