Any way around this if you've just purchase a home under a year old? I'm hiring a home inspector when we approach the one year mark in our new house.
There is nothing you can do about Mattamy roofs, the materials they use, or their Roofers lack of common roofing knowledge.
Mattamy roofers wrap themselves tightly in the Ontario Building Code's lame minimum standards. They don't even follow basic guidelines and fundamentals which tells me that they lack basic understanding with regards to shingle installation.
In fact, the OBC rules with regards to roofs are so poor and vague that virtually all other roofing companies in the country follow other guidelines set out by the
Canadian Roofing Contractors Assossiation.
Simple issues like exposed nail-heads are still common on 90% of Mattamy homes. Even when they are sealed, the job is done poorly. This reflects a bad attitude.
The OBC requires a "Starter Strip" at the eaves of roofs, yet often these strips are short, incomplete, or facing the wrong direction. At a home a week ago, the Starter Strips were short and incomplete at six locations. One area that was short, was clearly visible from the street and was in fact, the first problem I saw when I arrived at the house.
At gable edges, Mattamy Roofers usually don't install a Starter Strip at the edges. This small detail is required by the CRCA because it is recognised as a basic detail that should be on all roof edges. It improves the look, the strength, and water resistance to every roof edge. This detail would take 20 minutes of time and $20. in materials to do properly. I have no idea why Mattamy or any other builder would consider this acceptable.
The CRCA requires that the ridge shingles that overlap each other, overlap facing away from the prevailing winds. This prevents water from blowing under the shingles and soaking the structure at the peak of the house.
This costs nothing to do properly yet Mattamy roofers seem oblivious to this basic fundamental of shingle installation. In southern Ontario, the prevailing winds come from the west. Any Roofer that does not know this should go home and look for another job.
The Tarion Construction Performance Guidelines and the CRCA require that shingles overhang all roof edges a minimum of 12mm / 1/2" yet Mattamy's management has forgotten this major detail and has built hundreds of homes with this serious defect. In this case, the problem is not the Roofers fault, it's the fascia installers fault for extending the outward bend at the top of the fascia too far. This "mistake" should have been caught by Mattamy supervisors early on but has been missed. Now, like I said, there are hundreds of homes out there with this major defect.
In the last year I have been watching this "shingle overhang issue" get worse and worse only to find out that Mattamy has been sending people over to my clients homes who convince owners that these issues are not legitimate concerns. When I found this out, I contacted Tarion and arranged a meeting with Tarion and upper level Mattamy management. At this meeting they agreed that this issue was important and that they would improve this problem.
This however, does not fix the fact that many dozens of my clients were mislead and cheated from getting these legitimate repairs done. If, in the last year, I brought this "shingle overhang issue" to your attention during your inspection, only to be told by Mattamy that they would not fix this it, then please phone me. I will contact an individual at Mattamy who has assured me that these repairs would be done. In addition, I did contact the technical people at Tarion regarding this issue and they did agree the shingles must overhang the gable / fascia edge the minimum required 12mm / 1/2" but even they suggested 3/4" overhang was better.
Do your shingles properly overhang the edges of your gables ??
For those that don't know, a Gable is the upside-down V shaped roof. There are Gables on most roofs. Stand directly under the gable and look up. You should see the shingles overhanging the edge of the gable by at least 12mm or 1/2". Most roofers prefer a 3/4" overhang and consider that standard, so 1/2" should be the minimum amount to overhang this edge.
