Slate Roof Repair Summit, NJ
Most slate roofs in Summit that leak still have plenty of good slate, and the fix is usually new slates in a few spots and new flashing, not a new roof. Dial (908) 679-5768 to talk with a local roofer about the repair.
On a slate roof, the stone is usually the last thing to fail. Hard slate can last well over a hundred years and soft slate somewhat less, but in both cases the nails, flashing and valleys often wear out first. A slipped slate in the gutter is a common sign that the nails, not the stone, are failing.
Slate repair is a specialty, and the methods matter. Roofers cut the hidden nails with a slate ripper, set a matching slate and fasten it with a hook or a covered copper nail. Roof cement smeared over cracks and seams is a common bad repair that traps water and makes proper repairs harder later.
Stay off the roof yourself. 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.
Depending on what the roofer finds, slate roof repair in Summit, NJ can go hand in hand with slate roof replacement and slate roof installation.

Call nowThe process
What happens during a slate roof repair
Good slate repair keeps foot traffic off the stone and leaves no exposed nails.
Rig the roof
Before any repair, the roofer rigs ladders and brackets that keep feet off the stone. Work only happens when the roof is dry, since wet slate is slick.
Find the cause
Leaks are traced back to their source, which on slate is often a valley, a flashing joint or a cluster of slipped slates. Widespread slipping points to nail failure rather than isolated damage.
Pull damaged slates
With a slate ripper, the roofer cuts the nails holding the broken slate and draws it out. Nothing around the repair has to come off.
Set new slate
The new slate goes in and is hung on a slate hook, or nailed through the gap above and covered with a copper bib. Salvaged slate of the same type and color often gives the closest match.
Repair the flashing
Valleys and wall flashings that have rusted through are replaced with new metal, with the slates carefully removed and relaid. Copper is the traditional choice because it lasts about as long as hard slate.

Slate Roof Inspection Summit, NJ
A slate roof inspection decides whether the roof needs a few repairs or a bigger plan. 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.
A slate inspection on a Summit home relies on ladders, binoculars and drone footage more than walking, to protect the slate. The attic is checked as well for stains, daylight and rotted sheathing boards. You should come away knowing whether the roof needs a repair, a section relaid or a long term replacement plan.

Be wary of anyone who wants to tar the roof or tear off a roof with mostly sound slate at the first visit.
When looking for a slate roofing company in Summit, ask about past slate jobs and whether they keep salvaged slate on hand for matching. Matching size, thickness and color is what makes a repair disappear into the roof. One call to (908) 679-5768 is a good place to start.

Slate Roof Repair Near Me
Around Summit, most slate roofs date back decades, and many still have plenty of good slate left. Homes in Summit and neighboring communities such as Chatham, Mountainside, New Providence and Short Hills with original slate usually need nail and flashing repairs long before the stone itself wears out, and storms that drop limbs on the roof add broken slates to the list.
For slate roof repair in Summit, NJ or nearby towns like Chatham, Mountainside, New Providence and Short Hills, call (908) 679-5768 to reach a roofer who covers your street.
What the local climate does to a roof
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. That is why roof repair in Summit is busiest after a hard winter and before the next one.

Slate Roof Repair FAQ
How long does a slate roof last?
Slate is among the longest lasting roofing materials, with hard slate often lasting more than a century. The nails and flashing need attention long before the slate does. With timely repairs, many slate roofs outlive several generations of owners.
Is roof cement a good fix for a slate roof?
Tar patches on slate fail and make proper repairs harder. They dry out and crack, hold moisture against the slate and add work for the next repair. A real repair uses new slate and new flashing instead.
Is it safe to walk on a slate roof?
Slate roofs should be kept free of foot traffic. Slate breaks easily underfoot and becomes dangerous when wet. Slate roofers use hook ladders and roof brackets to keep their weight off the slate, so leave the climbing to them.
Do I need a new slate roof or just repairs?
Repair is the right call when most of the slate is solid and the problems are nails, flashing or a few broken pieces. Replacement makes sense when a large share of the slate is flaking, soft or breaking, or when nails are failing across the whole roof. A slate inspection shows which situation you are in.
Why are slates sliding off my roof?
Rusted nails are the usual cause. Older slate roofs were often hung with iron or steel nails that rust through long before the slate wears out, letting slates slide down and fall. 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.
