When it comes to roofing, a contractor’s perspective can shed light on what matters on maintaining one of the most vital components of any building. A roof does more than shield your family from the elements; it ensures the structural integrity of a property. Let’s look at some essentials and insights to know about your roof. Weather conditions, installation errors, and lack of regular maintenance can significantly reduce these lifespans. Routine inspections are critical to maximizing durability.
The Anatomy of a Roof
Understanding the components of a roof helps contractors diagnose and address issues effectively:
Roof Deck: The base layer, typically made of plywood, pine boards or oriented strand board (OSB).
Underlayment: A protective barrier between the deck and shingles, often made of synthetic material or felt paper.
Shingles or Roofing Material: The outermost layer that protects against the elements.
Flashing: Installed in vulnerable areas to prevent leaks.
Ridge and Ridge Vent: The peak of the roof and its ventilation system.
Drip Edge: Metal strips along the edges to guide water into gutters.
Gutters and Downspouts: Direct water away from the foundation.
Soffit and Fascia: Protect the roof’s edges and support gutters.
The lifespan of a roof depends on its material, installation quality, and maintenance. Here are the roofing types most often used in this area.
Asphalt and Fiberglass Shingles: 20-40 years – most commonly used and is most cost effective
Metal Roofing: 40-70 years – often used as a feature area on a roof. It is used more often in heavy snow areas. The labor and material for this roofing can be as much as five times more costly than shingles.
Slate Roofing: 50-100 years – hardly used on new construction. This roofing was used on many historical houses. This is more of a maintenance issue as the cost for this roofing is even higher than the metal roofing.
So, when can you overlay and when should you replace the roof? An overlay involves placing a new layer of shingles over the existing roof, while a replacement requires tearing off the old roof and starting fresh. Here’s how we evaluate the choice:
Overlay:
If the roof already has 2 layers, then a third layer cannot be installed as per the building code as it adds to much weight to the roof.
Suitable if the existing roof is in decent shape, with no significant structural damage.
Ideal for cost-conscious clients, as it saves on labor and disposal costs.
Replace:
Necessary if the roof deck is damaged or the current roof has widespread issues such as leaks, mold, or rot.
Provides an opportunity to inspect and address underlying problems, ensuring long-term stability.
How can your chimney impact your roofing? Chimneys can be a roofing challenge due to their potential for causing leaks. Here’s why,
Seam Vulnerabilities: The intersection of the chimney and the roof is prone to water intrusion.
Flashing Importance: Properly installed flashing around the chimney prevents leaks by directing water away.
Maintenance Needs: Regular inspections ensure that the mortar and flashing remain intact and functional.
If chimney-related leaks persist, we may recommend solutions such as installing a cricket (a small, peaked structure designed to divert water).
What is Flashing, and Why is It Important? Flashing is a thin material, commonly made of metal and installed at vulnerable areas of a roof to prevent water penetration. These areas include valleys, edges, around chimneys, vents, and skylights. Properly installed flashing ensures waterproofing and protecting the joints at vulnerable points.
From choosing the right materials to addressing unique challenges like chimneys and flashing, roofing requires a careful balance of expertise and attention to detail.
