Slate Roof Repair Leonia, NJ
A roofer in Leonia can repair a slate roof by replacing broken slates, rehanging slipped ones on copper hooks and renewing the flashing and valleys where most slate leaks start. One call to (551) 348-8956 reaches a nearby slate repair pro.
A slate roof leak rarely means the slate is worn out. Original iron or steel nails rust through, flashing corrodes and valley metal wears thin, and slates then slip, crack or let water past. Rusted nails let slates slip loose one by one, which is why slipped slates often show up in gutters.
Slate needs repairs done with slate methods, not shingle methods. The broken slate is removed by cutting its nails with a slate ripper, and the replacement is secured with a slate hook or a nail under a small copper bib so no nail is exposed. Coating slate with tar or roof cement only hides problems and stains the stone.
Look from the ground, not from the roof. Slate breaks easily underfoot and is slippery, which is why slate work is done from ladders and brackets rather than on foot. From the yard, note any missing or slipped slates, flaking surfaces and rusted metal at valleys or chimneys.
Slate Roof Repair is often paired with slate roof replacement and slate roof installation, depending on the cause.

What happens during a slate roof repair
Here is how a slate roofer usually handles a repair.
Rig the roof
Access is set up with ridge hook ladders and staging so nobody has to walk on the slate. Slate is never worked on while it is wet or icy.
Find the cause
The source is pinned down first, since a slate problem and a flashing problem are fixed very differently. If many slates are slipping, it tells the roofer the nails are failing roof wide.
Pull damaged slates
A slate ripper slides under the broken slate, hooks each nail and cuts it so the slate slides out without disturbing its neighbors. The slates above stay in place the whole time.
Set new slate
A replacement slate matched in size, thickness and color is slid up into place and held with a copper or stainless slate hook. Matching is easiest with salvaged slate of a similar type and age.
Renew the metal
Worn flashing is renewed by removing the surrounding slates, installing new metal and rehanging the same slates. Copper flashing is common on slate because its service life comes close to that of the stone.
What is included

Slate Roof Inspection Leonia, NJ
Inspecting slate is about telling a stone problem from a fastener or flashing problem. The inspector looks at the type of slate, the share of broken, slipped or flaking pieces, the nails where slates are missing and the state of every valley and flashing. Hard slate in good condition rings when tapped, while worn soft slate sounds dull and breaks easily.
In Leonia, a slate roof inspection is done mostly from ladders and with a drone so the inspector does not crack the slate checking it. Inside, the attic shows where water has gotten through and whether the board sheathing is sound. You should come away knowing whether the roof needs a repair, a section relaid or a long term replacement plan.

Slate Roofing Company Leonia, NJ
Choosing a slate roofing company matters more than with most roofs, because slate needs its own tools, methods and experience. Ask whether the crew uses a slate ripper, slate hooks or copper nails with bibs, hook ladders instead of walking the roof and long life flashing metal. Be wary of anyone who wants to tar the roof or tear off a roof with mostly sound slate at the first visit.
For Leonia homeowners, a good sign is a slate roofer who keeps a stock of salvaged slate and talks about repair before replacement. Matching size, thickness and color is what makes a repair disappear into the roof. Call (551) 348-8956 to talk with a roofer who works on slate.

Roofs in this climate
Cold winters bring snow, ice and a long stretch of freezing nights. Heat escaping from the attic melts snow on the upper roof, and the water refreezes at the colder eaves, which is how ice dams form and back water up under the shingles. Strong coastal storms push rain into every weak spot at the flashing and valleys. Most homeowners in Leonia, NJ have the roof checked in the fall and again after the snow melts.

Slate Roof Repair FAQ
What causes slates to slip?
Rusted nails are the usual cause. Many older slate roofs used nails that corrode in time, and once a nail fails, the slate slides out of its row. Each slipped slate is rehung with a slate hook or covered copper nail, and if slipping is widespread, the roof may need to be stripped and relaid with new nails.
Is roof cement a good fix for a slate roof?
Tar patches on slate fail and make proper repairs harder. They crack as they age, trap water against the stone and stain it, and they have to be scraped off before a proper repair can be done. The lasting fix is replacing the broken slate and renewing the flashing with metal.
Can I walk on my slate roof?
Slate is not made to be walked on. The stone cracks under weight, especially older slate, and it is very slippery when wet, icy or covered in moss. Slate roofers use hook ladders and roof brackets to keep their weight off the slate, so leave the climbing to them.
Can a slate roof be repaired instead of replaced?
Slate roofs are built to be repaired one slate at a time. It is when the slate is delaminating widely, or slipping everywhere, that a full strip and relay becomes the better plan. An inspection tells you which way your roof leans.
How long does a slate roof last?
Slate is among the longest lasting roofing materials, with hard slate often lasting more than a century. Fasteners and flashing are what wear out first, which is why repairs keep slate roofs going so long. With timely repairs, many slate roofs outlive several generations of owners.
