If your roof shows signs of damage, it may be difficult to decide whether repairing it is sufficient or it is more appropriate to have the entire roof replaced. Trusted roofing contractors such as Dunsmore Exteriors can help you determine which option is the best for your home. So, how do you know when to replace your roof?

Roof replacement is the best choice if your current roof shows signs of aging, is leaking or has storm or hail damage. Having your roof replaced is often a better solution than to repeatedly pay for roof repairs. 

Don’t hesitate to contact Dunsmore Exteriors if you want professional roofing contractors to inspect your roof and evaluate its condition.

Let’s take a closer look at the benefits you can expect from having your roof replaced by trusted roofing contractors.

Superior Durability

New roofs have superior durability compared to the older roofs. The stability of roofs decreases with age. A roof that is aged is more susceptible to damage caused by storms, high winds, and hail. Even a small problem can turn into an extensive issue if it is not addressed.

If you want to ensure your home is fully protected from the elements, consider a roof replacement. That way, you won’t have to worry about smaller roofing issues turning into an expensive nightmare.

Enhanced Energy Efficiency

A new roof will improve the energy efficiency of your home and reduce monthly heating bills. Unlike old roofs, especially those with some problems, a new roofing system will hold the heat better.

Old roofs can have various problems, such as leaks, missing shingles, rotting or damaged wood, among other things. Choosing to replace your roof with Dunsmore Exteriors means new shingles, proper underlayment (including winterguard and felt paper), and replacing damaged or rotted sheeting.

Peace of Mind

Roof replacement offers peace of mind in knowing that you and your family are safe. Deteriorated roofs make for an unsafe structure, putting you and your family at risk. With a new roof, you won’t have to worry about being nickel and dimed on small repairs anytime soon.

Increased Curb Appeal

Not only does a new roof prevent damage and keep you safe, but it also enhances your home’s appearance. Roofs are one of the most visible components of a home’s exterior, and when they have cracks or missing shingles, they can affect the overall appearance of a house.

Opting for roof replacement by Dunsmore Exteriors improves the curb appeal of your home and increase its property value. If you plan to sell your house in the future, keep in mind that replacing your old, deteriorated roof will positively impact your home’s resale value.

What are the Warning Signs that You Need a New Roof?

Signs that you need roof replacement are sometimes quite obvious, and in other cases, they can be very subtle. If you want to spot the warning signs on time, you should practice regular roof maintenance and look for signs of damage. Here are some warning signs you should watch for that it may be time to have your roof replaced:

Roof Leaks

Roof leaks are probably the most obvious sign that it is about time to consider roof replacement. To spot the leaks on time, you should inspect your attic regularly – it is best to do it after a rainfall because that’s when it is the easiest to notice the leaks. If you see signs of water intrusion, do not drag your feet – call Dunsmore Exteriors right away.

The worst thing you can do is wait because this problem will only get worse over time. Once we inspect your roof, we will determine the severity of the issue, as well as the best course of action for your particular situation.


If you notice algae, mildew, or mold growing in your home, this may mean that you have a roof leak. Algae is caused by moisture deposits on shingles, which allow spores to grow. Eventually, algae can eat away at your shingles.

Mold usually develops on wood, drywall, and other surfaces that absorb water, and it can cause health issues. Mildew is also harmful to your health if you are exposed to it for a prolonged period, and it is found on wet surfaces.

All these growths occur in damp environments, and if you see them in your home, it may mean that your roof is leaking and that you may have to replace it, depending on the severity of the issue.

Cracked or Brittle Shingles

If you notice cracked shingles on your roof, they are probably caused by extreme cold and wind damage. In case there are only a few cracked shingles, you can simply replace them with the new ones. On the other hand, if the cracks are dispersed randomly all over your roof, it is a warning sign that you may need a new roof.

Poor Energy Efficiency

If you notice your heating bills increasing year after year, a poorly insulated roof may be to blame. Most homeowners focus on door and window insulation as a solution to decrease their energy bills, and it often doesn’t cross their minds that their roof may be the culprit. If your energy bills are very high, it may be because your roof doesn’t hold the heat properly.


The lifespan of a roof depends on the materials used. Some roofs have a life expectancy of around 20 years, such as those with asphalt shingles, whereas metal and slate roofs can last several decades, maybe even more. If you are unsure of the age of your roof or the condition, give us a call, and we will get you scheduled for an inspection.
