Your roof is the first line of defense against the elements, shielding your home and loved ones from rain, wind, snow, and harsh weather conditions. However, missing or damaged roofing shingles can compromise the integrity of your roof. In this article, we will explore the risks of neglected roofing shingles and highlight the importance of addressing these issues quickly to protect your home.
Understanding the Role of Roofing Shingles
An asphalt roof is made up of three distinct layers: sheathing, underlayment, and shingles. Shingles are arguably the most important component of an asphalt roof as they provide the outermost and most durable layer of protection for your roof against water, wind, and sunshine.
Shingles are designed to efficiently pass water from one shingle to the next, preventing rain from seeping into the interior of your home. Shingles are designed to expand and contract together to prevent damage during drastic changes in temperature.
Under your shingles is a thin layer of roofing underlayment. Underlayment is generally made of synthetic felt paper that is designed to catch any water that seeps in beneath shingles and direct it off your roof. Synthetic underlayment is not meant to seal off your roof completely. Instead, it redirects any water that sneaks in beneath your primary line of defense, the shingles.
Sheathing is the structural component of the roof, made of plywood or particle board, to which the rest of the layers are secured.
How to Flash Ducting and Chimneys
The main goal of installing flashing is to get all the water that falls onto the roof to end up running down the shingles and not finding its way into your home via ducts or any other roof penetrations.
Most roof leaks occur at a vulnerable spot such as a chimney, vent, duct, or skylight. We’ll show you how to successfully install step flashing to protect your roof from leaks.
You’ll want to use step flashing to allow the water to cascade down the roof without any chance of encountering an unprotected spot. You’ll also need to account for wind, rain, and snow when installing your flashing. Don’t skip important steps because the natural flow of water wouldn’t be an issue. With the right conditions, almost nowhere on your roof is protected from the elements.
Following the slope of the roof, install several steps of flashing starting from the lower end of the duct or chimney and moving upward, creating a layered barrier of flashing and shingles, as indicated in the video.
When you’re installing the flashing along the topmost edge of the duct or chimney, make sure you use a single piece material. Using smaller shingles will give water a chance to leak into your roof structure because it won’t be able to run down the roof due to the duct blocking it’s path.
Depending on the state of your duct or chimney, you’ll want to attach the upper, unsecured portion of the flashing to the duct via screws and silicone to be extra sure that your roof stays water tight for years to come!
Benefits of Installing Drip Edge
Water Diversion: One of the primary functions of a drip edge is to channel rainwater away from the roof's edge and into the gutters, or onto the ground in the case of a roof without gutters. This prevents water from collecting or pooling on the roof, which can accelerate deterioration and cause leaks.
Protection Against Wind-Driven Rain: During heavy storms, wind-driven rain can be forced up and underneath the roofing material. A drip edge acts as a barrier, preventing water from infiltrating your roof's underlayment and deck.
Preservation of Fascia and Soffit: Without a drip edge, water can flow directly onto the fascia and soffit, causing wood rot, mold, and compromising the structural integrity of your roof's overhang.
Extended Roof Lifespan: By preventing water damage and ensuring proper water drainage, a drip edge contributes to your roof's longevity. It shields vulnerable areas from moisture, reducing the risk of decay and deterioration. Many other factors contribute to roof lifespan, but drip edges are one measure you can take to extend it.
Prevention of Ice Dams: In colder climates, ice dams can form at the roof's edge during winter, leading to water backup and potential leaks. A drip edge helps prevent the formation of ice dams by allowing water to flow freely into the gutters.
Proper Positioning: Drip edge should be installed along the bottom edge of the roof and along the sloped sides. It should extend slightly over the fascia and into the gutters.
Secure Attachment: Drip edge should be securely fastened to the roof's decking using roofing nails or screws. It's important to follow manufacturer guidelines for spacing and attachment methods.
Angled Design: Drip edge features an angled design that ensures water is directed away from the fascia and into the gutters, preventing water accumulation.While the drip edge may seem like a small detail, its impact on your roof's overall health and longevity is substantial. Installing a drip edge is a smart investment that pays off in the form of reduced water damage, prolonged roof lifespan, and protection against the elements. If you're installing a new roof or considering roof improvements, don't underestimate the importance of incorporating a drip edge into your roofing system.
