1) Drip edge or eaves starter - the main purpose of drip edge or eaves starter is to help keep ice from backing up over the eavestrough and up and under the shingles which leads to damaged shingles and possible leaks. Drip edge can be installed at either the eaves or the rakes (peaks) or both and it is never a bad option for our service areas like Orillia, Barrie, Midland, Gravenhurst, Bracebridge, Muskoka or Simcoe.
2) Flashings - all of the flashings and metal work we install are a pre-painted enamelled steel and there are various parts of the roof that need the metal replaced.
Chimney flashing is only replaced if necessary and sometimes it is removed while other times it is just replaced by going over existing flashing depending on how it was installed. A new chimney flashing ensures and protects against possible leaks at the base of the chimney and helps to preserve the integrity of the chimney structure.
Wall or step flashing - wall flashing goes on any horizontal areas where the roof surface meets a wall such as above a garage, overhang or under a window. Step flashing goes on any diagonal or inclined surface where the roof surface meets a wall such as above attached garages and down the sides of dormers. Both serve as an extra barrier to keep weather out of a possible entry point and to preserve the life of your roof along the outer edges.
Skylight flashing - this flashing goes around the perimeter of your skylight. New skylights generally come with the appropriate flashing kit. If you are re-using a skylight it is sometimes best to re-use the existing flashing and just reseal it with ice and water shield unless it is too deteriorated to do so.
Valley - steel valley material should be present in every valley whether the valley is "closed" or "open". An open valley is where you can see the steel valley and a closed valley is where you only see shingles in the valley area but there should still be a steel valley underneath. Most of our valleys are open as we believe that open valleys are less likely to leak since water and snow can run off more easily and closed valleys have faster shingle deterioration in that area setting the stage for a possible roof leak.
It's very important to have metal flashings in good shape on your roof, installed and caulked properly and checked regularly for possible cracks in the caulking as that is the most common areas we see leaks starting from.
