Cornerstone Roofing in Farmington Hills shares how to find hidden roof dangers before it’s too late.

When the roof on your home begins to show signs of age, when its shingles curl up or the roof looks wavy, it’s time to find professional help.

Victor Pintican, owner of Cornerstone Roofing in Farmington Hills, warns against waiting too long to repair or replace a roof on your home. Pintican should know. He started Cornerstone Roofing three years ago after working in the home improvement industry for more than two decades. Because he understands all aspects of building, Pintican helps homeowners avoid the pitfalls of a costly roof repair. Here’s how to tell if a roof is in need of replacement:

1. Look for a sign.

“The first sign of a roof in need of repair — its shingles will curl up,” Pintican says. “When you see this you know it’s time to have an inspection.”

2. Inspect it periodically.

Pintican says it’s a good idea to have a roof inspected about every 10 years to find any underlying damage before it becomes a costlier and more complicated project.

3. Don’t delay.

“A lot of people will wait until the last moment to have a roof replaced,” he says. “If there is a leak it can cause the plywood beneath it to rot.” Homeowners may not even notice the leak because it initially will not impact the drywall of a home, but the damage is done. It can cause mold and damage the insulation if it’s not changed in time.  That can become a costly fix.

4. Don’t just add another layer of roofing.

“Manufacturers will not warranty it,” Pintican says. “We don’t recommend it. Adding a layer instead of replacing a roof will shorten the life of the shingle by five years.”

5. Check the flashing.

In some cases, inexpensive materials are used in plumbing or sewer pipe flashing, which can crack after about 10 years, causing a leak. “Homeowners might not notice it until it’s way too late,” Pintican says.

Some signs of wear and tear are less problematic than others.

Darker spots on a roof may not necessarily mean it’s in need of a replacement immediately, Pintican says. “After 10 years you may see darker spots caused by algae, which can be removed,” he adds.

And the size and shape of a roof can mean a lot. When it comes to the pitch of a roof, steeper is better. It might cost more when it is time to replace it, but roofing will last longer because it dries faster in the elements, according to Pintican.

While most roofing is made to last about 30 years, there are factors that can impact its durability. In the 1990s, Pintican says an organic roof material was placed on many homes.  The material began to disintegrate and was found to last less than 15 to 17 years. It is no longer available, but Pintican and his team are now replacing many rooftops due to use of this organic material.

Expect a new roof to cost anywhere from $3,500 to $25,000 to replace, based on its size and pitch. A new roof should last 30 to 50 years, depending on the materials used. Today’s roofing is primarily made of either a tar-based substance called bitumen, or a rubber material called styrene butadiene styrene, which Pintican says will last longer but also costs more to install compared to other materials.

When it comes to repairing or replacing a roof, be sure to seek out a licensed contractor like Pintican. He provides inside knowledge of the building industry that can only benefit a homeowner who needs a roof inspected or repaired.

  1. My husband and I are new homeowners, so I wanted some maintenance and cleaning tips for our roof. I didn’t know you should have your roof inspected every 10 years to spot potential problems. I’ll have to keep that in mind to find a roof repair company that can replace shingles that are missing, thanks to this post!

  2. I’ve got your point here. Like what other people say, you will never know what will happen next time if you miss one step of the way. Neglecting our roof is a major problem in the future, don’t make everything too late. I don’t have anything to add up here everything you said is perfect as your blog, Thank you!

  3. Those tips you have given are very useful for all the homeowners. Never neglect the leaks and other damage of the roofing so that you will not have a big problem in the long run.

  4. I loved that you elaborated on the importance of inspecting your roof periodically to find any potential damage before it happens. My mother’s helper noticed that some parts of her roof look damaged, and we are looking for advice. I will let her know about the benefits of calling a roofing contractor to have her roof inspected.

  5. I loved that you elaborated on the importance of inspecting your roof periodically to prevent further damage. My husband and I noticed that the roof at my mother’s house looks damaged, and we are looking for advice about how to help her.

  6. I like that it is mentioned in this article that adding a layer instead of replacing a roof will shorten the shingle’s lifespan. On top of strategic avoidance of costly roofing work, I should also hire a roofing supplement estimate consultant just to be sure. I’d want to get the best price for my roofing so I can still come out with a profit after I sell it.

  7. My husband noticed that the roof in his office looks damaged, and we are looking for advice about what to do. I loved that you mentioned it is recommended to call a roofing company if you notice damaged or curling shingles. I will make sure to call a professional roofing company to help my husband.
