Houses spread along the river road on old orchard ground. Limbs over the ridge drop twigs into valleys. The wildfire plan's note on tussock moth damage in Westsyde from 2009 to 2011 is relevant only as debris: needles that remained fuel in the gutter. It is not a claim that moths hole shingles on a schedule. If a branch actually punctured the covering, photograph the limb and the hole from a safe spot and keep people out of the room underneath.
Say how far up the river you are
Westsyde Road is long. A crew that starts at Station 4's neighbourhood, 615 Porterfield Road, still needs your cross street. "Westsyde" will not do. The Westsyde hub explains why this is not Brocklehurst: more canopy, further from Tranquille, same 1.8 kPa side of the bylaw. The repair itself is still a boot, a valley, or a small hole, unless the deck is soft.
Valleys under trees, chimneys in the open
A Westsyde valley that stays damp under a canopy will grow a mat of needles even when the ridge looks dry. Have that valley cleaned and looked at, not only the hole you noticed from the kitchen. Where a lot opens toward the river, the chimney and the ridge take more sun and wind than the back slope. Describe both, or the repair will be sized for one weather and fail in the other. Manufactured homes were not verified as a Westsyde specialty. If you have one, say so, because the roof edge may be a different assembly than the framed house next door.
When the covering is generally done, switch to Westsyde replacement. For an active leak, call (236) 836-0303 with the cross street and whether a tree is still on the roof. A tree that is bringing down a line is 911, not a roofing form.
