Repair vs. Replacement - Which do I need?

Roofing problems are often intimidating and worrisome to most property owners. It can easily become overwhelming to try and determine the state they are in and if it is doing its job properly. Ensuring that your roof on your commercial or residential space is crucial for success and security. The last thing you want is to come home and notice water damage after a major storm, or other roofing malfunction consequences.

But how can you tell the difference between a minor repair and an entire replacement? Here are some of the warming signs that you need to be looking out for:

Missing Shingles

This is the most common and obvious warning signs that you need to call for a roof inspection. Your roof is as strong as it is shingles, and if they are falling off, your roof is becoming weaker by the second. If you start to notice shingles are falling or missing, you need to call your local roofing professionals as soon as possible.

Curling Shingles

If shingles are curling or buckling, you need to have your roof replaced entirely. This only happens when there is a defect in your roof, or it is well past its life expectancy. If you do not get this changed right away, you are going to start or continue to see interior damage from outside elements getting into your home or office.

Roof Sagging

You know how your roof should look—any noticeable sagging is a clear sign that something is wrong. This type of issue can signify deep structural faults in your attic or top floor or the foundation of your home. – if you witness this happening you need to contact us immediately so we can replace your entire roof. There is no way of getting out of this one. You need professional and respectful assistance.

Interior Signs

Your roof is meant to keep snow, rain, ice, and sun out of your home. If you are walking down the hallway and start to notice water damage, cool or hot air or light beams peeking through, you need to have an expert come out and inspect your roof. Often time this just calls for minor repairs.

Before your give us a call, take these factors into consideration so we can provide the best roofing service for you:

What is the age of your roof?

Roofs are designed to last 10-15 years. If you have approached or are near this mark, you should be monitoring your roof and have an inspector come out and look at your shingles. 

What is the extent of the damage?

If a few shingles have fallen or there are other minor issues, you most likely just need a roof repair. If there are large patches of missing shingles or leakage you might be looking at partial or full roof replacement.

What future do you have for your property?

Depending on your plans, its important to balance the options of a new roof. If you plan on living there for another 10+ years, you might as well invest in the replacement. If not, then choosing to repair might be the better option.

Questions That You Should Ask Your Roofing Contractor

If you are making the decision of choosing a roofing contractor solely based on a recommendation can be risky. This is why we have provided you with a list of questions that you should consider asking your prospective roofing contractor before you begin a roofing project.

1. Do you have proper insurance coverage?
Your roofing company should carry insurance that helps protect your home from any accidental damage that is caused. At L & D Wilson Siding & Roofing, our contractors hold at least $1,000,000 in general liability insurance.

2. Do you offer additional warranties and workmanship coverage?
Your roofing contractor should be able to offer a warranty that can include workmanship coverage. Our team offers different levels of roofing warranties that offer up to a lifetime of material and workmanship coverage.

3. Do you comply with all building codes?
Your roofing contractor should know and comply with all building codes, especially local codes.

4. Will you provide me with a written estimate?
The contractor that you decide to work with should provide you with a written estimate which includes an accurate description of the work that is to be performed and any work that may be contracted out.

5. Will you perform a detailed inspection?
In addition to inspecting your roof to see if there is storm damage, your contractor should perform a detailed inspection of your home’s entire roofing system. This includes inspecting the deck, attic, flashing, chimney, soil stacks, and any other roof penetrations.

Water and Ice Barriers for Your Roof

Roofing systems that are available in today’s market are the products of years of engineering achievements and innovations. A roofing system is a key part of your home or business, but it is not just one part, many components make up the system.

There are three main layers of a roofing system. The most visible layer is the roof shingles; however, the other layers include parts such as ice and water barriers, ventilation, insulation, and underlayment. All of these pieces work together to help your roof properly do its job. Because of their location on the roof deck, ice and water underlayment products help create a waterproof seal on your roof, ensuring that moisture is kept out.

How To Prevent Water from Reaching the Roof Deck

lands on the shingles and runs down the slope of the roof and into the gutters. These gutters then use downspouts and drains to move the water away from the foundation. When it comes to snow, it follows the same steps that rain does once it beings to melt.

In many situations, there are things that can disrupt the flow of water and cause standing water, which is not good for a roof. This water can cause a variety of problems, and eventually will make its way under the shingles and into your home.

Roof Leaks

There are certain conditions that can cause your roof to leak including:

1. Ice Dams
These are caused by melting snow that refreezes over the eaves and blocks the path to the gutter. Standing water on the roof can eventually start to seep underneath the roof shingles.

2. High Winds workmanship coverage?
These can lift up the edges of shingles.  Rain can quickly take advantage of these openings and infiltrate around the nails, which can then wet the roof deck.

3. Clogged Gutters
These are a double-edged sword for water issues. Water spilling over gutters can seep down into your home’s foundation. Water that pools into gutters can come up beneath the shingles and makes its way through the fascia and along any interior walls.

The reality is that leaves, seeds, and other objects get into the gutters of your home. Snow and ice also cause issues, but by making sure that you have an ice and water barrier, you can help make sure that the water doesn’t get too backed up and leak into your house.

What are Ice and Water Barriers?

One solution to solving water leakage problems is by using water and ice barrier underlayment below your roof’s shingles. When you adhere it directly to the roof decking, the barriers keep a tight seal around the nails and keep moisture from reaching inside of your home.

These barriers offer added protection to your roof and can be used in these areas:

1. Entire Roof Surface
Depending on where you live, it may make sense to utilize a waterproof barrier across the entire surface of your roof beneath the shingles. If your home is susceptible to losing shingles during storms, you can rest assured that the deck is secure against the rain until proper repairs are made.

2. Roof Penetrations
Any time you cut into the roof’s decking; you create an opening for water to infiltrate into it. Placing a barrier around skylights, vents, and chimneys allows you to seal off gaps around these more vulnerable areas.

3. Eaves
Your roof’s edges are exposed, and wind can catch the tips of shingles and lift them up. This lets water onto your roof deck, and then into your home.

4. Valleys
Your roof will have a variety of valleys and peaks depending on the architectural design. Rain trickles down from the roof and then collects in the valleys before it flows into the gutters.

Ice and water underlayments protect your home and create a waterproof barrier that helps not only protect your roof from rainstorms but from snow and ice as well.

Ice Dams 101

When you have the combination of below-freezing temperatures, heat loss from the attic, and rooftop snow, you can expect ice dams to form. The colder the temperature and the more snow involved, the worse the outcome.

Here is how an Ice Dam Forms:

  1. Snow collects onto your roof.
  2. The snow melts due to rooftop heat transfer from your attic.
  3. The melted water flows down the surface of the roof.
  4. It refreezes once it reaches the eaves, which creates a solid wall of ice.
  5. Additional snowmelt starts to pool behind the ice dam.

By eliminating the above issues, you can help prevent an ice dam from forming. Make sure that if you are suffering from ice damns forming on your home’s roof that you contact your local roofing contractor.

Synthetic VS Felt Roofing Underlayment

When most people think about roofing, they typically just think about the metal or shingles that are what you first see. What many people may not know is that there is another layer of protection that is located directly on top of the roof deck and under the roof coverings which performs a crucial role in making sure that your home is protected from moisture and damage.

Roofing Underlayment: What is it?

Roofing underlayment is the layer that lies between the roof deck (also known as roof sheathing) and the shingles. The roof deck is the layer that is typically made from plywood or OSB and has the underlayment installed right on top of it in order to provide an additional layer of protection from the elements.

There are two common underlayment materials: Synthetic and Felt

Each of these products has its own set of pros and cons, and the type that you choose may depend on roofing materials used, roof design, and budget, as well as what your roofing contractor suggests is best.

Synthetic Roofing Underlayment

For extra water resistance & protection from nature’s wrath, many roofers choose to go with a synthetic roofing underlayment. These products are usually created from long-lasting polymers, which provide longevity with added strength. This type of underlayment is moisture-resistant, and when properly installed, is better at protecting from the elements when compared to felt.


  • Durability: Synthetic roofer underlayment is known to be extremely durable. This type of underlayment does not tear and is tough against extended moisture and UV exposure. This type of roofing underlayment is also strong against foot traffic, which is important as your roofing contractor will be walking around on its surface as it is being installed.
  • Lighter: Compared to other types of underlayment, synthetic is up to four times lighter.
  • Safe: Synthetic underlayments are great for worker safety. The surface of our synthetic roofing underlayments features a variety of slip-resistant surfaces which enhance walkability. It is also typically well-marked with indicators of where the fasteners should be placed and overlay guides that help maintain accuracy and consistency during the installation.
  • Moisture-Resistant: Synthetic roofing underlayments are built to repel water. This is crucial for homeowners because it prevents any moisture from reaching inside of the home, causing damage such as mold or water leaks.


  • Many synthetic roofing underlayments are more expensive when compared to felt underlayments. The upfront investment in this type of high-quality roofing material can save you money down the road. This is why contractors recommend that even though it is more expensive, this investment is worth keeping your peace of mind.
