Flat Roof Repair and Maintenance (A Simple Guide)

Your flat roof is vital to the integrity of your home. But Toronto homeowners too often neglect their roof until there’s a leak or bigger problems like mould growth, structural issues, or damaged insulation. That’s why it’s important that you get your roof inspected periodically and know the basics of roof maintenance.

When Is the Right Time for Roof Inspection?

Homeowners too often only get their roof inspected for damage after a significant weather event. But you should be checking after your roof’s health more often than that.

In this regard, timing is vital. The best time to book a flat roof inspection in Toronto is before winter sets in. This is especially important if you have a newly installed roof because new shingles don’t seal down properly in cold weather.

Attempting roof repairs in winter can be dangerous, so any issues you discover during this time will have to wait until spring. Also, some repairs, like getting rid of moss and lichens, take time. In this case, the treatment works through the long winter, with the now-dead moss and lichen to be swept away in the spring.


Should You Have Your Roof Professionally Inspected?

Some obvious problems can be spotted without clambering up on your roof. But certain types of damage are invisible to untrained eyes. That’s why it’s important to hire a flat roofing company for a professional inspection, especially if your roof is older than a decade.


What Does a Professional Roof Inspection Entail?

An inspector will look for leaks, organic growth issues, unusual wear and tear, damage caused by debris from strong winds, or any problem that occurred during installation or previous roof repairs. There are four main facets of roof inspection:


Inspection of Structure

This is where they look for uneven roof planes and signs of sagging. Damages to your chimney and chimney caps; the condition of soffits, your gutter system, and fascia; and venting in your attic will also be checked.


Inspection of Material

Your inspector will check loose, curling, or missing shingles and fasteners. They will also look for stains, rust, and moss, and inspect for deterioration or gaps in the rubber boots and seals around the vent pipes.


Inspection of Interiors

Roof leaks can be dangerous to your home, so they look at the interior of your ceiling, attic, and interior walls for mould, rot, water stains, and other similar signs of water leakage.


Inspection of Workmanship

Problems in workmanship can sometimes lead to issues in the roof like leaks or other damage. Other red flags include incorrect flashing around roof penetrations like vent pipes, chimneys, and skylights.

You will get a detailed report after the inspection. If you require a roof repair, you will need to schedule it as soon as possible.


When Should You Schedule a Roof Repair?

Here are three things you should keep your eyes on. If you notice even the slightest sign of these, book the repair immediately.


1. Damaged Shingles

Take a good look at your shingles. If you see any missing, dented, or cracked ones, or if they’ve started to curl around the edges or have missing granules, it means they need attention. If it’s just a few shingles, it’s an inexpensive expenditure, but if it is widespread, you may have to call your flat roofing company.


2. Clogged Gutters

Leaves clogging your gutters aren’t a big deal. Simply clean them to be able to spot any other issue. However, if you find sludge, granules, or shingles while cleaning, it means your roof is deteriorating. So don’t wait around to call a professional for roof repairs.


3. Sagging Deck

A roof in good condition should appear straight along the lines. So, if you see an area that looks warped or sagging, call a professional to take a look. It could indicate a major problem that will only get worse.

If you come across any one of these three signs, it means you need a professional as soon as possible. There are a few things however that you can do to maintain your roof.


Tips for Maintaining Your Roof

Here are some tips to help you maintain your roof’s health.


1. Remove Debris

Loose gravel, dirt, and twigs left on the roof can retain water, and that moisture can damage the roof and aid in the growth of mould and algae.


2. Clean the Drain

Ponding can cause structural damage and leaks, which is why you should clean the field and auxiliary drains from time to time.


3. Check the Roof Surface

Keep checking your one-ply roof for holes, fastener back-out, or cracks, and your built-up roof for exposed felts and kissing gravel. Inspect all seams, seal cracks and holes, and schedule a professional roof repair. And try to avoid DIY roof repair ideas.


4. Check the Roof Penetrations

Drains, pipes, and other components protruding through the roof are susceptible to leaks, so inspect conduits, HVAC units, rain collars, vents, pipe boots, and gas lines from time to time. If you see any damage or leaks, call a roof repair professional right away.

Flat roofing has its pros and cons, but routine professional roof inspection and timely repairs can make it last longer. Need help? Call us at 416-699-2007.
