Not So Obvious Signs Your Roof Is At The End Of Its Life

inspect your roof before sell

Many times you can tell just by looking at your roof, that it needs repair. It’ll give you common signs like sunshine rays passing through or perhaps collapses. But there are times, the indicators are not that straightforward, and you may not know whether your roof needs repair or replacement, especially for commercial rooftops. Commercial buildings use different roofing materials and designs to support the massive footprints. As such, signs of deterioration aren’t that obvious. And again, it is easy to inspect the roof of your house as it is just a few feet up there. However, it’s almost impossible to get the view of an office building rooftop with over five floors, unless you go up to the ceiling. But even with that, you’ll be able to see only the common signs like the cracks and tears. Here are not so obvious warning signs that it might be time to call a roofer.

Not So Obvious Signs Your Roof Is At The End Of Its Life

Paying More Electricity Bills

Many reasons cause your energy cost to increase. But did you know that a bad roof is one of them? If it feels like you are trying too hard to control the weather inside your house, then it may be an indication that you need a new roof. A good start will be to take your electricity bill receipts over the last years and compare all relevant factors including the temperature. It’s best that you also put into consideration any changes that you made, which might be affecting the energy costs such as additional blinds. Make sure that you compare month to month. For instance, if February is less warm this year than last year, your electricity cost would be higher. But if the only thing you did was adding UV reflecting materials and the temperatures have dropped, but you still see a rise, that should raise your suspicions. Someone with a poor quality roof will be paying more money on energy because their roof is unable to efficiently seal the building hence unable to control the temperature. Which means, during warmer and colder climates the air conditioning system will use more energy to bring the temperatures inside the house to favorable degrees.

Presence of Bubbles and Blisters

Tears and cracks are visible signs that your roof needs replacement. But another indication that should worry you is if you notice bubbles and blisters on your roof. When liquid moisture is trapped on the roof membranes, bubbles are formed. If the problem is not solved right away, and the moisture is such that is trapped between the layers of the membrane or even the deck, blisters are formed. Science tells us that water evaporates when it is heated and enlarges the void that contains it. And with time, this leads to the creation of a blister. When the temperatures cool, the moisture condenses and creates a partial vacuum that can draw in air or water vapor via the tiny cracks. The process continues over a long time as the blisters enlarge and cause more damage to the membranes. However, the presence of blisters and bubbles doesn’t automatically mean that your roof needs repair. Check to analyze the damage (if any) first.

Rings of Dirt

After the rains, water dries up and leaves behind algae, fungus, dirt, and dust. If you don’t clean your roof regularly, moss could trap moisture against the roof which can damage it. Check mostly where the water puddles for any signs of moss. Remember, the more brown or green dirt rings or moss you have, the higher the chances that your roof may be nearing its end.

Your Roof is in its Late Twenties

Most roofs have a life span of between 20-30 years and some 50 years. Even if your roof is not showing any warning signs of poor performance, just the fact that it has stayed for over 20 years should be enough reason for you to make repair or replacement arrangements. It can be hard to tell if your roof is in bad shape especially if you are not a roofing expert. That is why it is essential that you have it inspected regularly by professional roofers. Doing that can help you know the early signs and fix them immediately before they become a bigger problem.

Converting Flat Roofs into Pitched Roofs

Why Use Flat Roof For Your Commercial Building

Interested in converting your existing flat roof into a pitched roof? If so, you probably know the possibilities pitched roofs offer, such as increasing storage space, curb appeal, and in some cases your living space. However, did you know a pitched roof requires less maintenance on average while reducing the risk of structural issues later? Although, there are some downsides to making the leap and converting a flat roof. For instance, pitched roofs can still leak, and pose issues. The largest setback many encounters is the overall cost.

To help you take a closer look into considering if the switch is right for you, we will go over the basics so you can decide what’s best for you.

Flat Roofs, Bad Reputation

Although flat roofs are commonly used on commercial structures, they typically have a poor reputation within the residential building business. A stroll around a flat roof enriched area will reveal this phenomenon clearly. Did you know there are insurance company’s that simply refuse to cover flat roofs? But, why?

They require consistent maintenance, replacing roofing materials, and the cost of installation. Over time, gravity results in a sagging structure because flat roofs have a single (slight) pitch. Meanwhile, repairs or installations are often used low-quality material. Even professionals could lack experience, leading to vulnerabilities, including undersized structural members and sections where the roof planes connection. Furthermore, residential properties do not typically use the higher graded roofing materials used by large commercial structures.

Methods of Roof Conversion

Depending on the situation, the flat roof can be removed or left while a pitched roof is built above it. Leaving the flat room installed lowers costs, but it adds additional weight to the structure that it may not be designed to handle. Removing the old flat roof costs more, but creates options for extra space, higher ceilings, etc. Pitched roofs can be designed and built using traditional rafter framing or engineered wood trusses. Finally, the decision to convert has to gain approval from a certified building professional or engineer.

Reasons to Consider Converting a Roof?

Below are common reasons why property owners decide to convert:

Maintenance: Original construction design was low-quality and/or improper causing constant leaks. While a single leak may not be enough to convert, experiencing multiple leaks in a short period could be.

Expense: Old flat roofs with significant structural problems could result in repetitive repairs and possibly a full renovation. In these situations, the repair expense can be within a range of installing a pitched roof.

Increased Lifespan: Flat roofs should have similar lifespans, but due to improper installation being common, and improved material quality, pitched roofs tend to last longer. Additionally, homeowners should compare overall high-quality durability between shingles and flat roof options, torch down, tar and gravel, and others.

Improved Ventilation and Insulation: Because of the limited space a flat roof offers, using insulation with high R-values are difficult, but not with pitched roofs. Also, a flat roof generally is not ventilated (and should not be in most cases), whereas a pitched roof can benefit from ventilation.

Additional Space: Sometimes that additional storage or living space is important. Many factors determine how much space is added, from slopes, house size, and structure. Others aim for visual appeal with raising the ceiling height.

Curb Appeal: The final choice here depends on the taste of homeowners. Modern home designs have utilized flat roofs for many homes for centuries, but most prefer the look, low maintenance and overall space from a pitched roof.

Selling: When selling a property, the roof could become the difference between a fast sale or sit on the market. Pitched roofs have become the favored modern style, while some still prefer the older flat roof look.

Reasons Not to Convert?

Pitched roofs, just like flat roofs will eventually leak from failing flashing, materials or metal pieces that cover joints. In other cases, roofing materials wear out over time or could have poor installation, repairs or low-quality design. Other elements may wear down or cause issues, such as the walls, a chimney, ventilation piping, etc.)

Frequently, property owners learn their issues are caused simply from improperly installed or low-quality materials, while the overall structure and roof design remain solid.

To determine if converting is needed, have your roof diagnosed by a professional. Simply upgrading the roofing to high-quality materials could provide the same lifespan of a pitched roof.
