How do I know if I need a new roof?
If you see that your shingles are torn, cracking or are curling, it is likely your roof needs replacing. If you see any staining on the ceiling inside your home, or blistering of paint, you may have a leak. Our consultants will be happy to come out to your home and advise you on what is required to repair your roof. As always, we offer free, no obligation quotes on your roof repair or replacement.


Do light coloured shingles last longer than darker shingles?
Light and dark shingles should last the same amount of time, given that they are installed on a house with a properly vented attic.  A key component to a longer lasting roof is proper attic ventilation.


How much will a new roof cost?
The cost of your new roof depends on size, shape slope and number of existing roof layers.  We offer free, no obligation quotes, so call us today to discuss your options.


Why are there dark streaks on my shingles?
The dark streaks that you see on your roof are commonly caused by algae growth.  They usually show up on the north-facing slope, the area of the roof that receives less sunlight.  There are new shingle products available which can help prevent this algae growth.  Please call us and we would be happy to explain the shingle options that help to inhibit algae growth.


Why does one side of my roof wear faster than the other?
Because UV rays slowly break down roofing material, the area of your roof that receives the most sun exposure will wear faster.
