Slate Roof Repair Dover, NJ
A roofer in Dover 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. Call (862) 430-1002 to reach a local roofer who works on slate.
Natural slate can last a century or more, so most slate repairs deal with what holds it on and what seals it. 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. 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 cracks under foot, especially older slate, and it is slick when wet or icy, so roofers work from ladders hooked over the ridge and roof brackets rather than walking on the stone. From the ground, binoculars show slipped slates, missing pieces and rusted flashing well enough to describe on the phone.
Many slate roof repair calls in Dover also turn up a need for slate roof replacement or slate roof installation.

How slate roof repair works
Slate repair follows a careful routine.
Rig the roof
Access is set up with ridge hook ladders and staging so nobody has to walk on the slate. Work only happens when the roof is dry, since wet slate is slick.
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.
Cut the old nails
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.
Hang a replacement
The new slate goes in and is hung on a slate hook, or nailed through the gap above and covered with a copper bib. Matching is easiest with salvaged slate of a similar type and age.
Fix the valleys
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 Dover, NJ
Inspecting slate is about telling a stone problem from a fastener or flashing problem. It covers slate condition, nail failure, valley metal, chimney and wall flashing and any old tar repairs. Tapping a slate is a quick test: sound slate rings, worn slate thuds.
A slate inspection on a Dover home relies on ladders, binoculars and drone footage more than walking, to protect the slate. 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 Dover, NJ
Choosing a slate roofing company matters more than with most roofs, because slate needs its own tools, methods and experience. Good questions include how they remove broken slate, how they fasten replacements and how they avoid walking on the roof. Be wary of anyone who wants to tar the roof or tear off a roof with mostly sound slate at the first visit.
For Dover homeowners, a good sign is a slate roofer who keeps a stock of salvaged slate and talks about repair before replacement. Salvaged slate that matches the original is the key to repairs that do not stand out. One call to (862) 430-1002 is a good place to start.

How the weather here affects roofs around Dover
Cold winters bring snow, ice and a long stretch of freezing nights. When warm attic air melts the snow, the meltwater runs down and freezes again at the eaves, building ice dams that push water up under the shingles. Strong coastal storms push rain into every weak spot at the flashing and valleys. Most homeowners in Dover, NJ have the roof checked in the fall and again after the snow melts.

Slate Roof Repair FAQ
Can a slate roof be repaired instead of replaced?
Most slate roofs can be repaired as long as the stone itself is still sound. 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.
What causes slates to slip?
The nails holding each slate are the usual culprit. 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.
Can I walk on my 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.
Is roof cement a good fix for a slate roof?
Tar and roof cement are poor fixes for slate. 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. A real repair uses new slate and new flashing instead.
How long does a slate roof last?
Hard slate can last well over a century, while soft slate lasts a shorter but still long span. The nails and flashing need attention long before the slate does. Kept up with repairs, a slate roof can serve for generations.
