Roofing FAQ's

Signature Exteriors developed a comprehensive Roofing FAQ page as an educational resource. The FAQ page is just another way to help homeowners have a good experience finding a qualified roofing contractor. Our goal is to help educate homeowners to make a roof repair decision that is truly best for them. Whether it’s using Signature Exteriors as your roofing contractor or not. Our company’s priority is to treat you as we would our neighbor before treating you like a potential sale. Why? Well, because that’s what we’d want for ourselves too.

We reference many different terms during our roof inspection recap. These terms can be confusing if you’re unfamiliar with the details of your roof structure. Signature Exteriors has provided roofing services for over 10 years with the sole mission of providing quality roofing services to customers. To us, that means educating homeowners on standard roofing terms and offering answers to frequently-asked roofing questions.

If you have a question but don’t see the answer here, please call us at (704) 729-4898 or click here to suggest adding to our roofing FAQ’s list!

Hail damage on roofs can cause dents, tears, and granule loss to shingles. Identifying hail damage to a roof often requires a physical inspection of the roofing system. Your homeowners’ insurance covers hail damage. Click here to schedule an appointment.

Roof Repairs

The quickest way to give you an accurate and fair quote on your roofing, gutters, or siding is to have our inspector complete their onsite inspection of your property. We do this to ensure that we account for all required materials and measurements before providing you with a quote.

It’s crucial to hire a roofing professional that is both licensed and insured. Another important item to consider is how long the contractor has been in business and what their customers say about them. 

We stake our reputation on providing high-quality roof repairs and offer a workmanship warranty with all services. 

Not all leaky roofs need a full roof replacement but, depending on the circumstances, it may be worthwhile to invest in a roof replacement. Our inspectors first need to complete their inspection but afterward, we will always be honest and upfront about the roofing solutions we think would work best for you and will provide free estimates for the cost of roof repairs or replacements.

We wrote an in-depth article in our blog titled: “Should I repair or replace my roof,” if you’re looking for more information.

Once your project is complete, we’ll send you your invoice electronically. We accept checks, credit cards, and debit card payments. Ask your Signature Exteriors representative if there is a processing fee associated with the method of payment you select.

Roof Replacements

Unfortunately, there isn’t a single set price for a roof replacement (and there shouldn’t be, so be wary of contractors offering such a deal). The cost of a new roof depends on the square footage, roof pitch, and the type of roof material selected. It’s essential to have a qualified roofing contractor perform an inspection so they can provide you with an accurate roof replacement quote.

On average, a residential roof replacement can take 1-2 days, except for larger roofs which typically take 3-4 days to complete. Our operations team will provide an accurate estimate of how long your roof replacement will take after we conduct your free roof inspection.

There are a lot of factors that influence the cost of a shingle roof vs. a metal roof. Most roofing materials are priced by the square (100 square feet) or the bundle (33.3 square feet). Asphalt shingle averages $80 – $120 per square before installation, whereas metal often ranges from $300 – $400 per square.

On top of the material cost, there is also the cost of labor (unless you’re a DIY-er). Depending on your area and local demand, labor costs can average around $200 – $300 per square to install asphalt shingle material onto your home. In contrast, metal roofing labor costs can range from $300 – $500 per square foot.

To get an accurate quote for your home, contact a local roofing contractor with experience in metal roofing to put together a comprehensive quote.

We wrote an in-depth article outlining how to prepare for a roof replacement!

  1. Remove fragile items from your walls: think pictures, mirrors, anything shakey on your shelves. The vibrations from roof replacements can often cause objects to fall from hangers.
  2. Clear the perimeter of your home: think patio furniture, barbeques, plants, sculptures.
  3. Prepare for noise: There will be constant hammering on your roof during your roof replacement.
  4. Parking: Park your car on the street or a nearby cul-de-sac so the materials may be delivered.
  5. Work Area: Keep children and pets away from the immediate work areas until the cleanup crews have finished sweeping for debris and nails.
  6. Cleaning: Our crews use the most up-to-date cleaning equipment such as rolling magnets, pin magnets, and metal detectors. Stubborn nails may remain hidden in brush and grass around the home. Please exercise caution for a few days after your roof replacement.
  7. Material Removal: We will send more material than is noted on your contract. Our goal is to ensure that we can complete your project promptly, so we send extra material to account for any unexpected hiccups (damaged shingles, etc.). We will have this material removed by our supplier within 1-3 days after your roof replacement.

Roof insurance claims vary depending on the insurance carrier and the storm damage (wind & hail) on your roof. We recommend checking your policy to see what your insurance provider covers. We will do everything we can to identify any storm damage, provide pictures and documentation, attend the adjuster meeting with your insurance carrier to ensure they’re documenting everything correctly. Having a Signature Exteriors representative present gives you the best chance for an approved roof insurance claim!

We work with all home insurance providers. Our in-house roof insurance claims specialists will make sure that the claim will cover any related damages so you can restore your home to its pre-loss condition.

Residential Roofing FAQ

Asphalt shingle roofing is the most common and, generally, the least expensive roofing material. Asphalt shingles are durable, reliable, and relatively inexpensive. They offer a wide variety of colors and styles, ease of installation, and they’re suitable for different climates and weather patterns. Asphalt shingle roofs should last about 20 years on average.

There are two general types of asphalt shingle roofs: 3-tab shingle and architectural shingle.

3-tab shingle vs Architectural shingle

3-tab shingle: composed of 1 flat layer and do not have a dimensional look. 3-tab shingles cost less than architectural but typically have a shorter life span.

Roofing term 3-tab shingle

Architectural Shingle: shingle tabs with various sizes and shapes and are thicker than 3-tab shingles. Generally a bit more expensive but offered with a longer life-span.

Roofing Term Architectural Shingle

Residential roofs can also be made of tile, wood, slate, and metal.

Metal roofing and asphalt shingle roofing typically have different installation costs due to the material. Installation costs are generally higher with any metal, tile, or slate roofing but they offer a much longer life span.

Types of Metal Roofing: Aluminum, Copper, Corrugated Metal, Metal Tile, Metal Slate, Standing Seam, Steel, Tin, and more.

Types of Shingle Roofing: Asphalt 3-tab Shingles, Asphalt Archictectural Shingles, Coal & Tar Shingles, Clay Shingles, Concrete Shingles, and more.

We wrote an in-depth article on the difference between shingle roof vs metal roof!

Most new residential roofing systems are designed with a life-span of 20-30 years. This varies depending on the type of shingle you select. The lifespan of a roof also varies depending on the quality of the material and the installation.

As shingles age they can show discoloration or streaking. Often seen on portions of the roof that receive less sunlight, these streaks are typically caused by algae growth. Discoloration or streaking is often just an aesthetic concern and does not always impact the life-span or waterproofing characteristics of your roof.

Although some do, we don’t recommend installing new shingle over the old shingle roof system. This practice is typically not covered by warranty, can cause unusual shaping, and it makes it impossible to inspect the decking underneath for rotting or deterioration.

A pitched roof is a roof with a sloping surface or surfaces. For a complete guide on different pitched roof types, check out our blog!

Commercial Roofing FAQ

Flat roofs are one of the most common types of roof for commercial buildings. Typically, building and re-roofing flat roofs is more cost effective than building or re-roofing other types of commercial roofing. There are many types of flat roofing materials such as EPDM, TPO, Modified Bitumen, and Built-Up Roofing.

Maintenance and drain cleaning is easiest on flat roofs since there is no pitch, they can walk easily and safely regardless of weather conditions.

Flat roofs experience a common issue with poor drainage since there is no pitch on the roof for water to run off. Standing water on flat roofs is a common cause for leaks on commercial buildings.

Often found on warehouses, factories, and apartment buildings. Low-slow roofing can appear flat but does have a slight pitch compared to commercial flat roofing. Low-sloped roofing for commercial buildings is designed to allow for water runoff. Low-sloped roofing materials often include EPDM, TPO, and Modified Bitumen.

There is no one roof system that works best for all applications. The answer to this varies on your specific building structure. Manufacturers for low-sloped roofing may not offer warranties on their material so it’s critical you work with a professional roofing contractor to get a detailed proposal for your unique flat roofing needs.

Our technicians are certified in EPDM, TPO, and modified bitumen.

Commercial roofing maintenance requires routine checks of sealant, membranes, caulking, and flashing.

If you’re noticing major water damage or interior staining, you should notify your local roofing professional immediately. In general, we recommend inspecting your commercial roof after a large storm, before any severe weather, and at the change of each season.

Gutter Services

Getting debris like leaves and twigs out of your gutter system is crucial for them to retain functionality. Debris can cause clogs, cracks, and holes in the gutter system. It’s generally recommended to clean your gutters atleast twice a year (Spring and Fall), but we recommend doing so more frequently if your gutters are located near trees or after a heavy storm.

Gutter cleaning can be made easier by installing gutter guards.

We always recommend homeowners have a functioning gutter system on their home as they’re built to re-route water away from your siding and foundation. They are essential to divert water away from your home and, if left neglected, can cause basement flooding, foundation issues, and even mold!

On average, gutter installation costs $4 to $9 per linear foot depending on the type of gutter material. However, not all gutter cost quotes are created equal. The price of gutter installation can vary depending on the size of the home and any other accessories you’re needing. As always, to get the most accurate quote, reach out to your local roofing and gutter contractor for a free estimate!

The best gutter material varies depending on your budget, climate, and if you want to add any flare to your home. Standard vinyl gutters are typically the most inexpensive option while copper tends to be the most expensive. Most homewoners opt for aluminum gutter material which has a mid-price point while still offering durability and decorative elements.

With proper care and maintenance, most gutters last between 15-20 years without needing any replacement. Copper gutters have a lifespan of up to 50 years! Small holes or cracks can often be sealed but if you’re noticing multiple areas with gutter damage, it may be time to opt for a new gutter system.


A gutter guard is any piece that attaches to the gutter and prevents unwanted material such as pine needles, leaves, and branches from entering the gutter system. Gutter guards prevent clogs and cracks in your gutters.
