The four most common reasons for a roof leak are pretty straightforward and are oftentimes, with proper annual maintenance and care, preventable. The most common causes are:
- Aged Roof Coverings — Sometimes roofs leak because they’re old — plain and simple. With time, all roofs will wear out, particularly asphalt-based roofs. If your flat roof is over 15 years old, or your pitched roof is over 25 years old, call a roofing contractor for an inspection to find out if it is in need of immediate repair or replacement.
- Clogged Gutters and Downspout Pipes – Rain and wind cause leaves and other debris to collect in the gutters and downspout pipes of homes, and without regular yearly clearing, the detritus may cause a serious blockage. Hire a roofing contractor, plumber, or handyman to service your gutters and downspout pipes prior to the arrival of the rainy season, as well as before any oncoming heavy storms, to ensure that your roof will remain watertight.
- Corrosion of Flashings and Metal Roof Accessories – Over time, the metal parts on your roof (flashing, pipe collars, copings, etc.) will corrode, especially if fabricated out of galvanized sheet metal. It is an obvious problem to spot – just look for evidence of rust, and fixing the problem will usually involve a pretty uncomplicated replacement. Pro tip: Always opt for a premium metal, like stainless steel or copper, instead of galvanized metal, when purchasing a new roof and/or flashing – you’ll have the peace of mind to know that your metal roof accessories will last for a generation or longer.
- Weakened Skylight Glass Seals – With changes in air temperature and moisture, the caulking used to seal skylight glass panels can weaken in as short amount of time as a two to three years post-installation, putting you at risk of a leak. Before the rainy season begins (or better yet, during spring and summer’s slow season), hire your roofing contractor to check your skylight glass panels and, if necessary, re-seal them.
And as always, don’t wait to spring a leak before you have your roof checked. Call a roofing contractor today!

One of the most common mistakes homeowners make when renovating is not having a roof checked prior to getting the work started.
If your roof is less than five years old, it should be too early to worry about any roof failures or corrosion, but keep in mind that with every passing year, it is worth keeping an eye out for corroded roof metals (flashings) or separations of the roof layers. And don’t forget to clean out your gutters and downspout pipes annually.
Renovations are expensive, and the rainy season isn’t over yet, so don’t waste hard-earned money and lose any home improvement work to something as avoidable as a leaky roof!
We often get callers who are unsure of what information to have ready when they decide to contact us. A few questions that your contractor will likely ask you:
- How old is your roof?
- Do you have a flat roof or a pitched roof?
- Are you currently experiencing a leak or other problems?
- Are you considering having your roof repaired, or would you prefer to have it replaced?
- How tall is your building (in stories)?
- Will a ladder be needed to access your roof?
If you have difficulty answering any of the above, feel free to speak with a representative. Otherwise, with the answers to these questions in hand, you should be able to schedule an estimate appointment with ease and confidence.

Fall is just around the corner, so here’s what you should do to keep your flat roof in good shape.
With summer’s long warm days, homeowners often allay their concerns about any existing problems with their roofs until the arrival of fall. Instead of waiting, we recommend to make most of what remains of the current seasonable weather and take a moment to inspect your roof.
To start, plan for either the morning or late afternoon, when the roof is cooler and the risk of damaging your roof’s surface is minimal. Bring a camera with you to document any problems or concerns you may encounter during your inspection.
Take a look all around and make sure that there isn’t any obvious signs of damage, cracks, or seam separations to the main roof membrane. Carefully check the edges of the roof, particularly the metal trim around the roof perimeter (called “flashing”) for signs of corrosion, separation from the roof membrane, and storm damage. Check all roof accessories, like chimneys and vent pipes, making sure they are sealed properly, fastened securely, and aren’t suffering from heavy corrosion. As for gutters and downspout pipes, clear away any debris, remove any obstructions, check for damage/corrosion/separations, and ensure that they all hardware are properly fastened in place.
If you see anything worrying, take a photo and call a roofing professional for their opinion. Consider having your roof coated (or re-coated) with a U.V. protectant to shield it from the elements. If your roof requires maintenance, repair, or replacement, don’t wait — have it done while the good weather lasts!
