SAGGING
If you notice there are parts of your roof that sag, this can be a very bad sign. Sagging is generally a symptom of structural damage in your roof such as inadequate bracing, inadequate spacing or structural failure. If you notice sagging on your roof, you definitely need to contact a roofing professional ASAP.
DETERIORATED FLASHING
If you have any exposed flashing on your roof (such as around your chimney), check it when you inspect your roof. If there are any loose, cracked, or deteriorated sections, then those areas should be repaired. If you notice leakage or water stains in or around any of these joints, you may have a more severe problem, depending on how long the flashing has been leaking. Moisture can cause rot and if it has infiltrated your house, you may have structural roofing damage.
MOISTURE
Moisture is the enemy of houses made in North America as most have wooden frames and moisture can eventually lead to rot and structural damage. Check your attic for signs of moisture leaking in from your roof in the form of: mould, mildew or watermarks on the wood.
TIME
What type of roofing material do you have? What was its estimated lifespan when it was installed? If you have a roof that was installed over 20 years ago, chances are you may need a new roof. Look for aging warning signs such as curling, pitting, brittle, cracked, or chipped shingles. For asphalt shingles, also look for bald spots where granules may have worn off. If more than one third of your roof’s shingles look to be in bad shape, then you will definitely need a roof replacement.
MISSING SHINGLES
A few missing shingles don’t often mean a full roof replacement, but depending on how many are gone and where they were pulled from, it may mean severe damage to your roof. Any missing shingles are a warning sign, because it might mean that the wind has pulled up a great deal of your shingles (even if they are still in place), and may have let water in, potentially damaging the wood below. Look especially for missing shingles around roof valleys, as these are the areas where rain and snow collect as they slide off your roof. Missing shingles here will mean leaks and often, greater damage. If you notice any of these potential warning signs, or are unsure of whether you might have a problem, don’t hesitate to contact us today!

First you need to determine where the leak is coming from. Unfortunately this is difficult to do when it is not raining. Once you determine where the leak is coming from, you will need to remove the shingles in the affected area. Depending on the extent of the damage to the roof, you may need to replace plywood in addition to the roofing paper and shingles.
