Here at Luso Roofing we get called in from time-to-time to fix a leaky roof. On this occasion the homeowner bought a brand new home off a developer. Two months into taking possession of the home the roof starts leaking! We came in to inspect the roof and we found no underlayment used at the eaves and the valleys?!
The Ontario Building Code requires a minimum two feet of felt paper underlayment along the eaves only, however, in this case no roof underlayment was used at all! To lower cost and raise profits some roofing companies will skip out on the installation of roof underlayment!
We believe that all roofs should have ice-and-water shield installed on all valleys and eaves. In terms of felt, halfway up should be a minimum requirement for all roofs other than garages. Roof underlayment is a secondary protector of your roof and there are many benefits to installing roof underlay, which will not be explained in this article. Tip to home owners, be weary of roofing contractors not installing roof underlayment on your home.
