Asphalt Shingle Roofing in Roberts Creek: Older Houses, Long Driveways and Uneven Wear

Drive Lower Road, or any of the lanes running off it, and the houses tell you how they were built. A core from the sixties or seventies. A bedroom wing added when the family grew. A sunroom closed in a decade later. A shop or a studio joined on at the back, sometimes with a breezeway between. A good number of them were framed by the people who lived in them, with lumber that was cheap at the time and spans that were decided on site.

From the driveway it reads as one house. From a ladder it is four roofs meeting each other at angles nobody drew.

That is the thing about shingling in Roberts Creek. The canopy and the debris get most of the attention, and they do matter — we went through what permanent shade and constant needle fall do to a roof in our post on metal roofing in Roberts Creek. But the part that actually decides how a shingle job goes on these lots is the building underneath: what it is framed from, how many times it has been added to, and how far it sits from the road.

Asphalt shingles are not our specialty and we do not pretend otherwise. Flat roofs are. We install a great many shingle roofs on houses that also have a low-slope section, and on a Creek house there is almost always a low-slope section somewhere. What follows is what we look at before quoting one.

Four roofs pretending to be one

Start with pitch, because it is not one number. It is normal on a Creek house to find a 9:12 or 10:12 over the original core, a 6:12 over a wing, and a 3:12 shed roof over an addition or a carport that was built to tuck under a window. Each of those is a different installation. The steep sections are straightforward. The shallow ones change what has to go underneath, and anything that has drifted below 2:12 is not a shingle roof at all, whatever is on it now.

Then look at where the additions meet. A hand-framed valley between a 1970s core and a 1980s wing is often built with the rafters simply landing where they landed, and the cricket that should divert water out from behind the join was frequently never built. Eaves rarely line up either. When one section sits 300 millimetres below the next, there is no course that runs continuously across the join, and trying to make one look continuous is how water gets behind the work. The correct answer is a deliberate, flashed break between two roofs, detailed as such and visible as such.

The sheathing is the part that surprises owners most. On one house you can find original 1x6 shiplap boards over the core, two different thicknesses of plywood on two additions, a patch of skip sheathing left over from a cedar shake section, and on an eighties add-on the occasional sheet of particle board that should not be holding a nail at all. That matters in three ways: fastener length has to change as the crew moves across the roof, holding power is not the same on every plane, and old boards cup, so the nail line moves and the finished courses show it.

Two more things we look for on this stock. A second layer. Overlaying a tired roof instead of stripping it was common into the nineties, and a Creek house with two layers has double the tear-off weight and a deck nobody has seen in thirty years. And the plane itself. Where a rafter was undersized for its span or a ridge has taken a set, the deck is no longer flat, and shingles telegraph a wavy deck mercilessly in low afternoon light. That is a conversation to have before the work rather than after: you are either paying to correct the plane, which usually means framing, or accepting that the finished roof will show what the framing is doing.

None of this is a reason to be gloomy about an owner-built house. They are often better built than their reputation and they have usually been looked after by someone who understood them. It is a reason the assessment has to be done properly, and a reason we take photographs of every plane and every deck type and give them to the owner, so the quote and the house are describing the same roof.

One roof, two lifespans

The mechanism is simple and we set it out in the Gibsons shingle post: under a second-growth canopy a north slope stays damp for most of the year while a south or west slope takes the sun, and the two sides of one roof wear at different rates. In the Creek that difference is wider than anywhere else on the lower Coast, because the shade is deeper and it never lets up.

The practical result is the finding we deliver most often here. One slope has six to eight years left in it. The other is finished — mat exposed in patches, edges curled, granules in the splash block. And the obvious question follows: can you just do the bad side?

Sometimes. Four things decide it.

• Colour. Shingles weather. A new slope beside an eight-year-old slope will not match, and if the two planes are visible together from the driveway or the road, you will look at that difference for a decade.
• The joint you are creating. Old work has to terminate into new work somewhere, and that somewhere is a ridge or a valley. A ridge is a reasonable place to stop. A valley is not: tying new courses into existing ones through a valley means re-cutting a detail that was already the hardest-working part of the roof, and you have manufactured a seam on purpose where there was none.
• Mobilization does not halve when the area does. Access, ground protection, the bin, the crew's travel and the first day of setup cost roughly the same for half a roof as for all of it. Two half-roofs five years apart cost appreciably more than one roof now, and on a lot with a long driveway the gap is wider still.
• Warranty. A manufacturer system warranty is written against a system installed in full, including underlayment and ventilation. If half the roof is new, ask in writing what is covered and what is not, rather than assuming.

Where doing one section is clearly right is when it is genuinely a separate roof: the shop, a detached garage, a wing with its own ridge, its own eaves and no shared valley. That is not half a roof. That is its own roof, and it should be quoted and warranted as one.

The driveway is part of the quote

On a Creek property the roof is often 100 to 200 metres from the road, up gravel, under limbs, past a well head and across or beside a septic field. Material has to go up that driveway and waste has to come back down it, and the waste is heavier than the material.

The arithmetic is worth having. A 2,000 square foot roof is twenty squares. Asphalt shingles run roughly 250 to 350 pounds a square depending on the product, so the old roof coming off weighs somewhere between two and a half and three and a half tonnes. If there are two layers, double it. And under a canopy in October it comes off wet, which adds weight that nobody estimated.

So before the crew is booked, several things get answered on site rather than on the day:

• Can the bin truck get in, and can it get under the limbs? A roll-off truck with its arms up is tall. Branch clearance is a measurement, not an optimism.
• Where does the bin sit? Close to the house is fastest. If the driveway will not take it, the alternative is a bin at the road and a dump trailer shuttling, which is slower and costs more, and should be priced as what it is.
• What is under the gravel? In the wet season a soft shoulder will take a loaded truck down to the axle. Ground protection where it is needed is cheaper than a repaired driveway.
• Where are the well and the septic field? Nothing heavy parks on a field, and nothing gets staged on a well head. On rural lots this is the first thing we ask and the thing most often not marked.

Then disposal, which deserves a line of its own. A tear-off load goes to a transfer station and the tipping is charged by weight. Ask whether the quote includes disposal or estimates it, and if it is a per-bin allowance, ask how many bins are allowed for. On an old house that may have two layers, an unstated bin count is the single most common way a shingle quote turns into a larger invoice.

Worth noting that this is a different logistics problem from the one metal creates. For a metal roof the difficulty is length — panels that want to arrive in one piece down a driveway that bends. For shingles it is weight, in both directions. Same driveway, two different conversations.

Staging a tear-off under trees

The first job on a Creek roof is sweeping it. You cannot read a deck through two years of needles, and you cannot see which valleys have been holding water. That half hour before anything comes off tells you where the surprises will be.

Then the question of how much roof to open at once. The standard is not negotiable: the roof is watertight at the end of every working day. Under a deep canopy the practical consequence is that the sections get smaller, because the deck does not dry between showers the way it does on an open lot in Gibsons or on the water at Davis Bay. Underlayment follows the tear-off closely rather than catching up in the last hour, and on a borderline day that is the difference between a dry house and a ruined ceiling.

The canopy also sets the clock. A Creek roof drips for a couple of hours after the rain has stopped and the sky has cleared, so a start here can be genuinely later than a start fifteen minutes down the highway on the same morning. That is scheduling, and it should be said out loud rather than discovered.

Two more practical points on treed lots. Overhanging limbs within reach of the work have to come back before the roof goes on, both so the crew can work safely and so the new roof starts its life clean. Tree work is a separate trade on a separate quote; we do not do it, and a roofer offering to take a bit off with a chainsaw from the roof deck is describing a different kind of risk than the one you hired them for. And in late summer, nests. Wasps in a soffit or behind a fascia board are a legitimate half-day delay, and pushing on through it is how someone comes off a ladder.

Ground protection on these lots is not only about the house. Plywood and tarps go against the walls and over any glass, but you are also protecting plantings, a deck the crew cannot see from above, and whatever is stored along the north wall of a rural house, which is usually quite a lot.

What it costs in the Creek

We quote architectural asphalt shingles at $5.50 to $9 per square foot installed, before 5% GST, with 20 to 25 years of service on the Coast. On a 1,900 square foot roof area that is roughly $10,450 to $17,100.

Where a Creek house lands in that range is driven by:

• The number of separate planes and the pitch inventory. Complexity is the main reason two houses of the same area quote differently, and it bites harder on some materials than others — the full version of that argument is in our metal versus shingles post.
• Deck work. On owner-built framing with mixed sheathing, some replacement is likely. Insist on a stated price per sheet of plywood so the allowance is a number rather than a surprise.
• A second layer to remove, which changes both labour and disposal.
• Access. How far material and waste travel between the driveway and the roof, and whether a bin can reach the house.
• Tree work by others, and disposal, stated separately.

On permits: Roberts Creek is in the Sunshine Coast Regional District, and SCRD Building Bylaw No. 779 (2025), section 4.3(h), exempts replacement of roofing on a standard building unless the replacement results from building envelope failure. A straight re-roof needs no permit. But structural work needs a permit everywhere, and on this housing stock that is not a remote possibility: sistering a rafter, re-framing a sagged section, or correcting a span that was never right is structural work. If your assessment turns up framing, expect a permit to be part of the plan. The boundary between exempt and not exempt is worth reading carefully, and we walked through it in the Gibsons post.

There is no ferry premium on our pricing. Coast work is booked in blocks: crew, materials and equipment cross together and stay until each roof is watertight.
