Leaks are often the first sign that something is wrong. Make sure you inspect your roof and gutters twice a year. Look for cracked, warped or missing shingles or tiles or excessive surface granules accumulating in the gutters – these can all be visible signs that your roof has a problem. Indoors you should look out for bubbled or peeling wallpaper, cracked paint, discoloured plasterboard or anything out of the norm. Remember, the longer you leave a problem the more expensive the solution can become.
