Roof Replacement vs. Roof Repair

Repairing a roof is a big job, but replacing a roof? It doesn’t get much more significant. And how do you know whether you should repair or replace your roof? Here are five factors to consider that will help you answer that question:

Commercial Roofing St. Charles.

Commercial and residential roofs have the same function: Protection against the elements. However, that is where the similarities end. 

Commercial roofs differ from residential ones in a few significant ways: size, materials, slope, and price tag. Instead of the shingles or panels, you see on houses, commercial buildings often use heavy-duty stuff like single-ply materials (think TPO, PVC, EPDM), concrete, modified bitumen, built-up systems (BUR), or even tar and gravel.

Unlike the typical pitched roofs on homes, commercial ones are usually flat or just a bit sloped. They can also have unique shapes and tricky spots that make installing them a bit of a puzzle.

Installing roofs requires the same basic skills, whether for homes or businesses. But because commercial roofs are more complex, hiring a commercial roofing contractor who knows their way around the project is much more critical.

Factors to Consider

Here are factors to consider when choosing a roofing company and what type of roof you want for your home or business.

These include:

  1. Reputation: Does the roofing company you’re considering have a good Google review? What are people saying?
  2. Cost: Purchasing a new roof is a considerable investment, and you’ll have to balance the need to save a little now vs. the desire for your roof to last longer and require less maintenance. Always get 2-3 quotes to compare.
  3. Lifespan: Some materials last longer than others, and there will likely be an inverse relationship between cost and lifespan, but it pays to have a roofing contractor explain where you can find the best value for both.
  4. Warranty: Warranties will vary based on materials, roof type, and brand, with some offering more excellent coverage for a longer duration than others.
  5. Maintenance: How much time or money do you want to spend maintaining your roof, as this will differ too based on some factors?

Types of Roofing

Asphalt Roofs

Asphalt roofs consist of shingles made of asphalt-saturated bases, which can be made from organic materials or fiberglass. Organic shingles contain a combination of asphalt, waste paper, ceramic granules, and salt coatings. In comparison, fiberglass shingles are made from glass fiber coated in asphalt and minerals like stone, ceramic, slate, quartz, mica, and schist.

The advantages of choosing an asphalt roof include:

  • Durability and lifespan
  • A large variety of colors to choose from
  • Wide choice of shingle shapes and sizes
  • Relatively straightforward repairs
  • Eco-friendly and sustainable options
  • Wind and fire resistant

We have partnered with CertainTeed because their asphalt roofs offer superior quality and value.

Certainteed’s asphalt shingles are a reliable, high-quality choice whether you’re more interested in beautifying your home or protecting it. CertainTeed has developed valuable technologies that help homeowners build better, safer, more comfortable homes. Imagine how good your home would look with a new roof.

Metal Roofs

Whether you’re looking for a roof for your home or business, metal roofing is a worthwhile consideration for the following reasons:

  1. Longevity: Metal roofs have a life expectancy of 40+ years.
  2. Safety: Metal roofing has strong fire retardant properties.
  3. Energy efficiency: Metal roofs reflect radiant heat from the sun, which keeps your home cooler in summer.
  4. Environmentally friendly: Metal is one of the most eco-friendly roofing materials.
  5. Ease of maintenance: How does no maintenance sound to you?
  6. Increased value: A professionally-installed metal roof can command higher rent and resale prices.

When it comes to metal roofing, there are two brands we trust the most: Central States and ProVia.

Central States Manufacturing

Central States Manufacturing has several panel roof types designed to look great and outperform traditional shingles. Central States has you covered regardless of your taste or environment (as in St. Louis hail storms).

The Central States has metal roofs for every budget. They have many styles, from classic and historical to modern and upscale. They also have varying levels of dent-resistant panels, benefiting the crazy St. Louis weather.

ProVia’s metal roofing combines the beauty of cedar shingles or clay tile with the durability of a professionally-engineered metal roof system. And a metal roof from ProVia will likely be the last roof you’ll ever have to buy. 

Whether you want to improve your home’s curb appeal and value or get 50+ years of protection, ProVia likely has something for you. Imagine having a roof that requires little to no maintenance. Imagine saving money on utility bills. And Provia’s metal roofs are made right here in the USA using domestically-sourced materials.

Slate Roofs

Slate is a highly durable metamorphic stone. Proponents of slate roofs will tell you that slate provides today’s longest-lasting roofing options. And slate roofs have become increasingly popular, primarily due to their distinct beauty, longer-than-average lifespans, and warranties that cover more and last longer.

The advantages of choosing slate roofing for your next roofing project include these five factors:

  1. Aesthetics: Beauty is in the eye of the beholder, but most people agree that slate roofs are stunning.
  2. Durability: Slate roofs are made of naturally occurring stone that can easily withstand the worst weather Mother Nature can toss.
  3. Lifespan: Regarding longevity, slate roofs are the gold standard, with the best slate rated to last 75+ years.
  4. Low maintenance: If slate roofs are rugged as a stone and nearly waterproof, maintenance issues will be few, far, and few between, if at all.
  5. Home value: Want to increase your home’s value? Top it off with a slate roof.
American Slate

We have partnered with American Slate for all of your slate roofing needs. The natural beauty of their slate roofing conjures images of the world’s most incredible mountain ranges. Every piece of their handcrafted slate is unique, with numerous customization options.
