But not only at the exterior of your roof you can detect problems. When inspecting your roof, also head to the attic to look for any of the following problems:

• Leaks around the chimney, vents, etc.
  
  >>> check out the problematic spots and try to seal them with IKO Shingle Stick.
• Sagging between rafters
  
  >>> a professional roofer or carpenter can try to brace it from the inside but this is not always a possibility.
• Cracks on roof sheathing
  
  >>> this can be temporarily fixed from the attic space but a complete renovation must be done before the winter.
  
  Snow loads can cause bigger damage/
• Proper ventilation
  
  >>> check if the intake and exhaust openings are not plugged or too small. The air under the deck must circulate freely.
• Signs of moisture
  
  >>> somewhere there is improper ventilation, check the full ventilation system.
• Visible light from the outside
  
  >>> control and repair the metal flashings around the chimney.
• Signs of damage from pests
  
  >>> repair damaged parts if possible and protect the roof attic from the pests.

Even problems that seem minor, such as small cracks or cracked roof shingles need to be addressed right away. Fixing problems and keeping up with the standard roof maintenance is the best way to ensure the longevity of your shingles roof.

If you are unable to safely access your roof or if you are uncertain about your ability to detect problems, we advise you to contact a professional roofing company.

Good luck and a happy spring and summer season!

A successful roofing project requires more than only the right shingles. The job has to be done properly, following the correct application methods. In our previous blogpost we covered the first 5 common roofer mistakes. The list of mistakes doesn’t end there, let’s take a look at the following 5 topics:

• Improper shingle nailing
• Use of improper nails
• Not aligning shingles correctly
• Improper flashing installation
• Reusing old flashings

Shingles can slide down or blow off if they aren’t nailed correctly or if less nails have been used. You should use at least four nails per shingle. When installing a roof with steep graded, that minimum should be raised up to six nails. The placement of the nails is as important as the number of nails. They should be completely covered and kept dry by the next row of shingles. All nails should be driven straight into the wooden deck. Crooked, over-driven or under-driven nails can cause roof leaks!

Solution:

Unstick the shingles carefully and try to fix all under-driven and high nails. Secure these spots with an extra bituminous mastic. But be aware: an excessive amount of mastic can cause blistering! Cover exposed nails with a piece of shingle or apply a small dot of Shingle Stick and some granules over it.

Shingle alignment - both vertical and horizontal - is required. The best way to ensure that the shingles are horizontally aligned in new applications is by the use of a chalk line. Especially for tab shingles, the use of chalk line is highly recommended. The bottom edge of laminated shingles must align with the tops of the saw teeth of the shingles in the underlying course. Too high alignments increase the chance of wind blow off and wind driven rain backing up under the shingles.

Solution:

When the roof doesn’t leak this is only an aesthetical problem.
