Architectural shingle

Laminated asphalt shingles with a shadow line that reads like wood or slate from the street. The best value per year on most homes, and the easiest to repair.

Two layers of fibreglass mat and asphalt bonded together, with ceramic granules on top. The laminated second layer gives the ragged, dimensional look and roughly doubles the weight of the old three-tab shingle, which is most of why it lasts longer in wind. We install it as a full system: synthetic underlayment over the whole deck, ice and water shield at eaves, valleys and every penetration, pre-bent drip edge, starter strip on eaves and rakes, and six nails per shingle on every job, not just in high-wind zones.

Lifespan

25–30 years

Wind rating

110–130 mph

Weight

240 lb/sq

Minimum pitch

2/12 (4/12 without extra underlayment)

Impact rating

Class 3 standard, Class 4 option

Typical install

3–5 days on a typical home

What it does well

+

Lowest cost per year of service on most homes

+

Any roofer can match and repair it for decades

+

Over 30 colours, so it suits almost any siding

+

Class 4 impact-rated versions cost about 10% more

What to weigh up

–

Granules wear off faster on south and west slopes

–

Hail over 1 inch will bruise standard grades

–

Needs a full tear-off when it is done, around the 25-year mark

How we install it

Tear-off to the deck, deck check with photos, 6-nail pattern, closed-cut or metal valleys, shingle-over ridge vent balanced with soffit intake.

Looking after it

Clear valleys and gutters each autumn, keep branches 6 feet off the roof, and look for loose granules in the downspouts after year 15.

Best for

Most houses, most budgets, and anyone planning to stay 10 to 25 years.

Standing seam steel

Continuous steel panels with raised, concealed-fastener seams. Sheds snow and hail well, reflects heat, and never needs a tear-off again in your lifetime.

24-gauge steel with a factory paint finish, roll-formed into panels that run in one piece from eave to ridge. The seams stand 1 to 1.5 inches proud and the clips that hold each panel are hidden under the next seam, so there are no exposed screws to back out as the steel expands and contracts. It goes over high-temperature underlayment, and every trim piece (eave, rake, ridge, valley, wall) is bent to fit on the job.

Weight

Typical install

What it does well

+

Outlasts two or three shingle roofs

+

Sheds snow cleanly, with snow guards over doors and paths

+

Hail usually dents the finish rather than breaking the seal

+

Light enough to suit older framing

What to weigh up

–

Two to two-and-a-half times the cost of shingle up front

–

Dents from large hail are cosmetic but permanent

–

Needs a crew that knows metal: poor trim work is where these roofs leak

How we install it

Tear-off, high-temperature underlayment, panels formed to length on site, hidden clips at 24-inch centres, vented ridge with closure strips, snow guards where roof meets walkway.

Looking after it

Almost none. Rinse off tree debris, keep dissimilar metals (copper, pressure-treated wood) from touching the panels, check sealant at pipe boots every 10 years.

Best for

Modern and farmhouse styles, low pitches, and houses in hail corridors.

Stone-coated steel tile

Steel pressed into a tile or shake profile and coated in stone granules. The look of tile at a fraction of the weight, with a Class 4 impact rating.

Galvalume steel panels pressed into a barrel tile, shake or shingle profile, coated in acrylic and bonded stone granules. Each panel covers about the same area as eight to ten clay tiles, and they fasten to wooden battens, which leaves an air gap that helps the attic run cooler. The granule coat hides small dents, which is why it holds up so well in hail.

+

Walkable for maintenance, unlike clay

What to weigh up

–

Costs more than shingle and has fewer colour choices

–

Granules can shed in the first year and collect in gutters

–

Not every roofer carries the trims, so repairs need the right supplier

How we install it

Tear-off, synthetic underlayment, counter-batten system on steep slopes, panels screwed to battens, profiled ridge and hip caps, closed valleys with factory trays.

Looking after it

Flush gutters after the first year of granule shedding, then an autumn check like any roof. Scratches can be touched up with the manufacturer's granule kit.

Best for

Homeowners who want a tile look without reinforcing the roof structure.

Natural slate

Split stone laid by hand with copper nails. Heavy, slow to install and expensive, and on the right house it will outlast the people who paid for it.

Metamorphic rock split into slates 3/16 to 3/8 inch thick, holed and hung with two copper nails each, lapped so that every point on the roof is covered by at least two layers of stone. Most of our slate work is restoration in Ashford Old Town, where we keep the sound original slate, replace the broken ones with reclaimed stone of the same colour and rebuild the flashing in lead or copper. On new slate roofs an engineer checks the rafters first.

How we install it

Structural check, battens or solid deck with felt, slates hung with copper nails and a 3-inch headlap, copper or lead valleys and step flashing, snow guards on long slopes.

Looking after it

A look from the ground each spring for slipped slates, and a flashing check every 10 years. Slipped slates are refixed with copper tingles, not sealant.

Clay tile

Kiln-fired barrel or flat tiles that keep their colour for decades. Excellent in heat, fragile underfoot, and always needs an engineer to check the rafters.

Natural clay shaped into barrel (S or two-piece) or flat interlocking tiles and fired in a kiln. The colour runs through the tile, so it never fades the way paint or granules do. The tile itself rarely fails; the underlayment beneath it does, usually at 25 to 30 years, so on older clay roofs we often lift the tile, replace the underlayment and battens, and relay the same tiles with 10 to 20% new stock.

Cedar shake

Split western red cedar that silvers to grey within a few years. Beautiful and breathable, but it needs cleaning and treating to reach its full life.

Hand-split or taper-sawn western red cedar, laid over spaced sheathing or a breathable mat so the wood can dry from both sides. We use pressure-treated, fire-retardant grades with stainless steel nails, because bright or galvanised nails stain and corrode within a few years.

What to weigh up

–

Needs cleaning and treating every 3 to 5 years

–

How we install it

Tear-off, breathable underlayment or interlayment felt, spaced sheathing where needed, two stainless nails per shake, 1/4-inch gaps for swelling, copper ridge strip to slow moss.

Looking after it

Blow off debris twice a year, keep branches trimmed back for sunlight, clean and apply a preservative every 3 to 5 years, and replace split shakes as they appear.

Cedar shake

Split western red cedar that silvers to grey within a few years. Beautiful and breathable, but it needs cleaning and treating to reach its full life.

Hand-split or taper-sawn western red cedar, laid over spaced sheathing or a breathable mat so the wood can dry from both sides. We use pressure-treated, fire-retardant grades with stainless steel nails, because bright or galvanised nails stain and corrode within a few years. The warm red colour silvers to grey within two to three summers unless it is treated.

Tear-off, breathable underlayment or interlayment felt, spaced sheathing where needed, two stainless nails per shake, 1/4-inch gaps for swelling, copper ridge strip to slow moss.

Looking after it

Blow off debris twice a year, keep branches trimmed back for sunlight, clean and apply a preservative every 3 to 5 years, and replace split shakes as they appear.

Under 10 years, architectural shingle is almost always the best value. Ten to 25 years, shingle or stone-coated steel. The rest of your life, standing seam or slate start to pay for themselves.

Below 3/12, only standing seam steel (or a membrane on porches) keeps water out reliably. Slate wants 6/12 or more. Everything else is happy between.

Can the structure take the weight?

Can the structure take the weight?

Slate and clay weigh three to six times as much as shingle. On a new install an engineer checks the rafters first. If they need reinforcing, stone-coated steel gives a similar look at a fraction of the weight.

Kestrel Heights sits in the valley’s main hail corridor. Class 4 shingle, stone-coated steel and standing seam all hold up far better, and some insurers lower the premium for them.

What does it cost per year?

What does it cost per year?

Divide the installed price by the years it lasts. Shingle, clay and steel tile land close together; cedar costs the most per year once you add its upkeep.
