Greeley Roofing: Article About Weatherproofing Techniques
When you look at your roof, you see a layer of asphalt shingles, tiles or metal. This layer is typically the aesthetic layer, or the layer designed to cover up the building materials underneath. Like siding or paint, the aesthetic layer acts as a superficial barrier but really offers little protection against the elements. The real safeguard against inclement weather comes in the form of underlayment. In order for your Greeley roofing system to work, you need layers of underlayment to protect your home against water intrusion. Here is an outline of different modern weatherproofing techniques.
If your home has eaves or valleys, then you'll need extra protection. Any time the roof's direction changes or intersects with another story or object, this change increases the likelihood of water penetration. Contractors install a waterproofing membrane onto areas like these in order to offset the risk of water exposure. In areas that receive a lot of snow and inclement weather, waterproofing membrane may be required by local building codes. If you're unsure, just ask your local development office for a guidebook on building codes.
In drier areas, waterproofing isn't always required, and you can save some money by forgoing the installation. However, keep in mind that extra weatherproofing is never a bad decision. One freak rainstorm could undo your entire roofing system via leaks.
On top of the waterproofing membrane or in lieu of this layer, a layer of felt will be installed.

The felt layer acts as an additional shield against water exposure. Contractors nail this layer down in sections. As a DIY project, layering felt is relatively simply, but you need to pay attention to the nail placement.
Modern roofing materials have evolved from traditional products like felt paper, which means you have more options for the type of material you install. The latest trend in weatherproofing centers on synthetic underlayments made from materials like fiberglass fabric, polyester and polypropylene. Synthetic underlayments offer better protection than their felt predecessors in terms of moisture resistance, tearing and UV blocking. They're also lightweight and can last on an exposed rooftop for six months while builders work on the roof.
Before final installation of the top aesthetic layer, roofers install flashing around the same areas they put waterproofing material. Chimneys, skylights, valleys, seams and joints all need this layer to prevent water from building up under the roof. Made of corrosive-resistant metal, flashing ensures that water runs off of sensitive areas in order to mitigate water damage. For extra precaution, roofers will install drip edges around the edges of the roof. Drip edges encourage water to run off smoothly from the roof, thereby preventing water from collecting on the side of the house.
