M&R Roofing

This roof replacement was completed 9 years ago and as you mention we have returned to address any warranty issue in the past so some patience based on that history and the fact that the initial work was completed with no issue as you yourself mention would be appreciated. We never said that it would not be addressed this time around or in the future either, but will so on our schedule which is very busy this season as we attempt to prioritize our commitments. None of this suffices a 2-star review to get our attention. It certainly does not help in contractor and client relations.

The issue at hand is not asphalt shingles falling off. The asphalt shingles are still intact. There is no exposed wall area as you can see from the photos. These "laminate" (architectural) asphalt shingles are composed of two parts, the base layer and the second layer that cover only the exposed bottom half of the base layer and is adhered to the base layer with asphalt. The shingle is nailed in the middle through both layers, however this second layer appears to be slipping away from the base layer (i.e. de-laminating). This is unrelated to our installation workmanship. It is simply the product de-laminating. I wouldn't even fault it as a manufacturer failure, I would say that given the following circumstances, asphalt shingles may not have been the best solution for that vertical wall. The front mansard wall is almost vertical so the asphalt shingles do not lay on the wall. Instead they hangs, which contributes to the slippage pressure and possibility that the second layer that is only adhered to the base layer with asphalt and a nail at the very top of the second layer can slip over time. Especially so, since the that wall has lots of sun exposure due to it's south western exposure and the shingles also being black and absorbing the heat. This heat causes the asphalt that is adhering the two layers to run and the layers to de-laminate even slip around the nail. So, given the recent heat wave we have had, these couple of shingles have de-laminated. Please note this has began to occur in the ninth year of the installation. In hindsight, though it is an economical solution to install asphalt shingles on a vertical wall, when exposed to south west direction and lots of sunlight and heat over the years, conventional vinyl, aluminum or other siding as on your neighbours mansard wall would be preferred.

Again, we are will address this de-laminating issue within the warranty period. However, I think a 2-star review and a review at all to address this issue is unnecessary, exaggerated and unfair. Unfortunately, this seems to be the age that we live in. Please contact us directly to address this issue.
