Flat roofs are a modern and stylish alternative to traditional pitched roofs. Massachusetts homeowners are increasingly opting for flat roofs for new home construction or for replacing existing roofs. Flat roofs require less material than pitched roofs, making them a good economic choice. They’re also highly energy efficient because they eliminate the space between the bottom of the roof and the top of your house.
However, like any other part of your house, flat roofs are susceptible to wear and tear. The experts at Dynamic Roof Tech share the warning signs of flat roof damage and how to know whether you need a simple repair or a whole new roof.
Warning Signs of Flat Roof Damage
Some signs of damage are easy to spot, such as when you go outside after a storm and notice pieces of your roof on the ground. Other signs may be harder to see, especially for non-professionals.
We strongly recommend calling an experienced, trustworthy roofer as soon as you notice any signs of damage to your flat roof, or after major weather events. Only they have the expertise to spot and assess hidden damage.
Leaks
Flat roofs aren’t technically 100% flat. They’re built with a minimum of slope for water drainage. However, since they are far less sloped than their pitched counterparts, they’re more prone to leaks. Leaks can enter your home and cause even more damage that can be expensive to fix.
Any of the following may be signs of a leaky roof:
- Ceiling stains
- Mold or mildew
- Water in your attic
- Wet or soft walls
Ponding Water
A leaky roof inevitably leads to ponding water around your home, which promotes the growth of harmful bacteria or algae. Not only can these growths damage your roof’s materials, but they can also be hazardous to your health.
Note, too, that ponding water doesn’t only happen due to leaks. Because of their extremely low pitch, water can stagnate on the roof without leaking into the building. This stagnated water can wear away at roofing materials if not addressed quickly.
Blisters, Bubbles, or Cracks
If your flat roof was installed by a trustworthy roofer, they will have sealed it to protect it from harsh weather, including UV rays in the summer. Over time, though, that seal starts to wear away. As the seal degrades, the materials of the roof blister, bubble, or crack – known sometimes as “alligatoring,” due to the similarity to alligator skin.
Shrinking Roof Materials
Here in Massachusetts, we’re subject to extreme weather fluctuations: hot summers and cold winters. Enduring hot and cold over and over again causes roofing materials to expand and contract throughout the year. Usually, this is fine. However, over time, the constant movement will cause the roof to shift and the materials to warp, potentially leading to leaks.
Wind Damage
Whether from major summer storms or harsh winter blizzards, we get lots of strong winds in coastal Massachusetts. While you may know that wind can blow shingles off pitched roofs, you might not realize that flat roofs are also affected. Flat roofs are typically made from a single layer of material, so when strong winds hit, the entire roof may sustain damage.
Age
No matter how well-constructed and installed, no roof is safe from the effects of time. Flat roofs can last 20–30 years, sometimes even longer. If your roof is at least 20 years old, or if you’re not sure how old it is, we strongly recommend a professional inspection.
Repair Vs. Replace
Once a professional roofer confirms that there’s damage, should you repair or replace the roof? Your pro will offer their own expert opinion, but here are some factors to consider as the homeowner:
- Age of the roof
- Plans for your property
- Extent of damage
- Cost
Repair
Repairs are typically advised for minor damage. It’s often cheaper to repair small problems than to remove and replace the entire roof. For example, if the only problem is a single leak, and the rest of the roof is generally in good condition, a simple repair will save you time and money.
Replace
Unfortunately, sometimes a full roof replacement is the only logical solution. If you find yourself paying for repairs in the same spot, it might make more sense to invest in a new roof installed correctly.
Similarly, if you’re considering selling your house soon and your roof is 20 years old or older, it might make sense to replace it. This increases your home’s ROI on the market.
Any type of major or widespread roof damage will almost certainly require a new roof.
Maintenance Tips for Flat Roofs
While you can’t help time and weather affecting your flat roof, there are a few tips you can follow to help keep it in the best shape possible:
- Professional inspections: Conduct them about once a year – and definitely after extreme weather events – call a trustworthy roofer to inspect your roof. They’re trained to spot problems you might not be able to see.
- Gutters and drains: Clean and clear them every spring and fall.
- Don’t neglect signs of damage: Any signs of damage listed earlier should be taken seriously to avoid becoming major (expensive) problems.
- Stay off the roof: You should only go onto your roof to check for debris or damage.
