Q: How much does it cost to replace a roof?
A: The short answer is...it depends. Variables like square footage, the pitch of the roof, the quality of roofing material used and the removal of old roofing materials (if necessary) all factor into the cost. Other budget variables include obtaining a roofing permit, city license, labour and if it is a 1 or 2-story home.

Q: Can I apply new shingles over existing shingles?
A: Yes we can apply new shingles over the existing shingles. It depends on the condition of the roof. Although it can be done, we recommend that we remove and start from scratch.



Q: How can I ensure proper performance from shingles in cold climates?
A: Make sure that the roof is properly ventilated. When applying ridge caps, keep the shingles that are being used as ridge caps in a warm place so that they will be flexible enough to bend. When re-covering an existing roof with new shingles make sure that the old shingles are flat.



Q: What is winter curling?
A: They are roofs that have slopes of 4:12 or less. Never apply asphalt shingles to slopes that are below 2:12. If you do they do not last as long as shingles on steeper roof pitches, due to the increased exposure to sunlight and other weather conditions.



Q: What are low slope roofs?
A: Make sure that the roof is properly ventilated. When applying ridge caps, keep the shingles that are being used as ridge caps in a warm place so that they will be flexible enough to bend. When re-covering an existing roof with new shingles make sure that the old shingles are flat.



Q: What will happen if my roof is not properly ventilated?
A: Asphalt odors from hot shingles entering the home’s interior. Blistering, curling or premature aging of asphalts shingles. Splitting Rotting of wood decks. Bucking



Q: How much ventilation do I need on my roof?
