The Roofing Process
The Normal Process of Building a Plano Roof
All roofs start with the framing, which determines the shape of the roof, and the insulation. The insulation is not technically part of the roof. Still, it’s an essential component of how well your roof regulates the temperature in your home.
On top of the framing goes the roof deck, which is typically plywood sheets. This material is secured directly to the framing. A water barrier then goes over the plywood sheets to protect the sheets from moisture. Then the Dallas roofer adds the underlayment, which adds protection and a smooth surface to attach shingles.
At this point, the roof does not look much like a residential roof. The starter strip is added to the roof’s edges, ensuring that the roof’s underlayment seals. From there, it’s on to the shingles, tiles, or metal sheeting that give your roof its signature roof.
Once the laying is complete, roofers add the last pieces to seal the roof. This process includes the ridge caps, which go over all the peaks of the roof. It also includes flashing. Flashing is generally metal that molds around anything that sticks out, like chimneys, ventilation, and dryer vents.
What is a Roof Overlay?
Putting in a replacement roof in Dallas is a process that often includes labor and disposal costs as well as the new roofing materials. A roof overlay is an alternative to roof replacement once your roof starts showing signs of failure.
Signs of failure include:
- Roof leaks
- Missing shingles
- Rust spots
- Broken gutters
Shingles are the typical material for roof overlays. Rather than removing the old roof, a roofer puts down a new layer of shingles over the old one. Some Dallas roofers may also add additional flashing or other roof layers depending on the specific roof issues.
When Taking the Old Roof Off is Necessary
While roof overlays are a good option for many Dallas homeowners, a roofing company must carefully evaluate whether it’s the right choice for the home. There are as many reasons a roof overlay will not work as there are that it would.
First, an examination of local building codes is necessary. For example, many municipalities restrict shingles to two layers, regardless of the addition time. Additionally, there may be material restrictions that affect your decision.
Another reason to do a roof replacement is underlying problems. While overlays may extend the life of your roof, they cannot fix all the possible structural problems like leaks. Adding a roof overlay can actually compound these problems.
Third, while shingles may not seem heavy, some roofs are not built to hold the additional weight. Unfortunately, older homes or those not built to code often have these structural failures that you must correct at your own expense.
