Spray Foam Roofing is a common word used in the building industry, but still not as readily used in our market. There are typically 2 types of spray foam used today. One is an open cell foam insulation and the other is a closed cell foam insulation.
You said it just right. Its all our own benefit to inspect our roofs by professional inspection team. Great post. Thanks for sharing.
Hi Michael,I am a roofer in Toronto and was called by my city customer to come and look at her cottage up in Port Sydney, Ontario. She has been having "leaking" since june and based on the pictures I thought it was maybe ice damming, but given she noticed the leaking in June I was puzzled. Then she told me leaking was coming from the peak where the ridge ventilation was installed. My next thought was maybe that was installed incorrectly. She then told me the insurance company was called and they had an engineer who said "condensation" was the trouble. I found this blog post and believe based on your comments it is a few things.Her cottage is on the side of the hillthere is multiple levelsI am not sure if is was a year round cottage for the previous owners.She paid for the road to be regraded, a new 20,000 roof was put on and the roofing compnay has come out several times to fix or upgrade this roof.This poor woman is at her wits end as she is looking at 50,000 in interior damages.In a desperate attempt to get an "honest roofers" opinion she commissioned me and my roofer to go up a few sundays back.There was already a foot of snow up on her roof and from what we could see this 20,000 roof she installed was of excellent quality workmanship and top quality products.We opened up the soffits and notice very little insulation and what appears to be wet marks.WE know that she plans to use this year round, maybe the former owners only used it in the summer who knows.Given you seem to know alot about condensation and cottages are there any questions I need to ask her to get conclusive answers.Given your blog I now think it is condensation , can water really "pour" down a wall and through beams if it is condensation?I look forward to your response.take careTrish
