Marley TIle roof repairs

Skylight Replacement

Cementing & Changing Valleys

Cementing & Changing Valleys

 

Old skylights on Marley tile roofs don’t just fog up—they leak, waste heat, and pull the whole roof down with them. We don’t patch. We replace.

We supply and install premium Velux skylights that fit your existing curb perfectly. If the old frame has rotted or shifted, we rebuild it from the outside—new pressure-treated curbs, precise cuts, no shortcuts. Every new unit gets custom lead flashing, hand-formed and soldered on site, integrated so tightly with the Marley tiles that water has nowhere to go.

The result: brighter rooms, lower bills, and a roof line that looks like the skylight grew there. One visit, permanent seal, zero callbacks—even after the worst Toronto ice storm.

Done once. Done forever.

Cementing & Changing Valleys

Cementing & Changing Valleys

 

Old lead valleys on Marley tile roofs look fine for years—until they don't. Freeze-thaw cycles, thermal expansion, and decades of water flow cause the lead to fatigue, crack, and tear along the folds. Once that happens, water slips behind the lining, rots boards, and turns a small split into major interior damage.

We don't patch lead. We remove it completely and upgrade to heavy-gauge steel valley liners—ribbed for debris flow, fully supported on new boards, and woven under the tiles with proper overlaps. Then we re-cement the tile edges with reinforced mortar that flexes instead of cracks.

No more tears. No more hidden leaks. The valley handles Toronto downpours and ice buildup without blinking.

One upgrade, permanent quiet.

Re-Flashing Chimneys

Cementing & Changing Valleys

Re-Cementing Hips & Ridges

 

Chimneys are the first place leaks show up on older Marley tile roofs. Surface-mounted flashing pulls away, cheap solder joints fail, and water works its way behind the tiles straight into the attic.

We don't surface-mount. We cut a clean reglet into the stone—deep enough for the counter-flashing to lock in without relying on caulk that cracks in two seasons. Then we dress 4lb lead sheet (Code 4 equivalent, heavy enough to last decades) over the base flashing, tuck the top edge into the reglet, and wedge it tight with lead slugs before pointing with flexible sealant.

Every corner gets double-lapped and bossed by hand. Step flashing weaves under each Marley tile. The result: a seal that moves with the chimney, shrugs off freeze-thaw, and stays watertight long after lighter materials would tear or corrode.

No mortar beds that shrink and crack. No callbacks—even on exposed Toronto chimneys.

Permanent from the brick to the tile.

Re-Cementing Hips & Ridges

Re-Cementing Hips & Ridges

 

Hips and ridges take the worst beating on any Marley tile roof—wind uplift, thermal movement, and decades of settling cause the old mortar to shrink, crack, and fall out entirely. A simple re-point often fails in one season.

We strip the loose material clean, reset any shifted ridge tiles, and lay galvanized wire mesh reinforcement bedded into the mortar in multiple passes—dense, flexible, and locked to the mesh so it can't pull apart.

The finished line is straight, weather-tight, and strong enough to handle Ontario's freeze-thaw cycles without a single crack for decades.

No crumbling beds. No loose caps rattling in the wind. Just a solid crest that protects the roof below—permanently.

Eave closures (Bird stops)

Re-Cementing Hips & Ridges

Eave closures (Bird stops)

 

 Open eaves on Marley tile roofs invite birds, squirrels, wasps, and wind-driven rain. Once pests get in, they can damage underlayment, block ventilation, and create costly nesting problems. Cheap plastic or foam closures crack, shrink, or blow away in the first winter.

We install custom-fabricated galvanized steel eave closures (bird stops) cut on-site to fit your exact tile profile. The steel is bent to sit snug under the first course of tiles. No flimsy inserts that fall out. Just a clean, permanent barrier that protects the roof edge for decades—without needing replacement.

Wall Flashings

Eave closures (Bird stops)

 

Where a Marley tile roof meets a sidewall or abutment, poor flashing is the silent killer—water drives down the wall face, slips behind the tiles, and rots sheathing before you ever see a ceiling stain.

We don’t rely on surface strips or caulk that peels in five years. We install 4lb lead chased into a reglet cut in the brick or stucco. Every step is shaped tightly to the tile that driven rain has no path inside—even on tall gable walls exposed to Toronto wind.

No mortar fillets that crack and fall out. No shortcuts that leak the next season. Just a permanent, invisible seal that protects the junction for decades.

One proper installation, zero wall leaks.

Frequently Asked Questions

Please reach us at Conor@alexanderslate.com if you cannot find an answer to your question.

 

Common issues include leaks around chimneys, skylights, valleys, or hips; missing, cracked, or slipped tiles; deteriorating mortar in ridges/hips/valleys; animal intrusion (squirrels/birds); moss/algae buildup; or damaged flashings. In Ontario’s freeze-thaw climate, small problems escalate quickly to water damage or structural issues. At Alexander Slate, our expert inspections catch these early—contact us for a thorough assessment to protect your luxury home.


 

Yes—Marley tiles (concrete-based) are no longer produced in Canada, but repairs are fully feasible. We source high-quality reclaimed Marley tiles or exact-match alternatives, ensuring seamless integration in color, profile, and durability. Our master artisans handle replacements without disrupting the roof’s elegance or performance, often extending lifespan by decades.


 

No—high-pressure washing can erode tiles, dislodge mortar, damage flashings, and force water under tiles, causing leaks. We use only gentle Soft Wash techniques with low-pressure, eco-friendly solutions to safely remove moss, algae, and stains while preserving your premium Marley roof’s integrity.


 

Costs vary by scope. As Ontario’s #1 rated luxury specialists, Alexander Slate provides transparent, no-hidden-fee quotes after inspection—repairs are often far more cost-effective than full replacement.


 

 Yes, many repairs (e.g., flashing, tile replacement, leak fixes) are possible in winter with proper safety measures and tarping. Ontario’s cold weather can worsen issues like ice dams, so prompt action prevents interior damage. We prioritize emergency winter repairs for discerning homeowners.


 

 With our premium methods—reinforced mortar beds, heavy-gauge flashings, custom closures, and precise installations—repairs often last 20–40+ years, matching or exceeding the original roof’s performance. We focus on permanent solutions: done once, done forever.


 

 Leaks typically stem from cracked/slipped tiles, shrinking/cracked mortar in valleys/hips/ridges, failed flashings at chimneys/skylights/walls, or poor animal-proofing at eaves. Freeze-thaw cycles accelerate these in Ontario. Our comprehensive repairs address root causes, not just symptoms.


 

 We recommend professional inspections at Bi annually or after major storms, plus 3-5 year gentle Soft Wash cleanings. Early detection prevents costly escalation—trust Alexander Slate, Ontario’s premier tile roof experts, for proactive luxury care.


 

 Yes—common in Ontario (squirrels, raccoons, birds). We install custom galvanized steel eave closures, seal entry points, and repair any resulting damage (chewed flashings, displaced tiles) while preventing future issues without harming animals.


 

 As Ontario’s #1 rated luxury roofing specialists, we deliver artisanal, permanent restorations using premium materials and techniques—no shortcuts or callbacks. From Toronto estates to GTA homes, we treat every Marley roof as a masterpiece. Schedule your private consultation today.
