Slate Roofing
Slate Roof Repair Oradell, NJ
Most slate roofs in Oradell 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 (551) 383-2310 to talk with a local roofer about the repair.
On a slate roof, the stone is usually the last thing to fail. Original iron or steel nails rust through, flashing corrodes and valley metal wears thin, and slates then slip, crack or let water past. When nails rust through, slates slide out of place and leave gaps, a problem sometimes called nail sickness.
Repairing slate the right way uses tools and materials made for it. 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. Tar on slate is a shortcut that fails, and removing it later adds work.
Do not climb onto a slate roof to look. Walking on slate breaks it and is dangerous when the stone is wet, so slate roofers use hook ladders and staging instead of walking the field. From the yard, note any missing or slipped slates, flaking surfaces and rusted metal at valleys or chimneys.
If the problem goes deeper than it first looked, an Oradell roofer may also recommend slate roof replacement or slate roof installation.

The slate roof repair process
Here is how a slate roofer usually handles a repair.
Stage from ladders
The roofer sets a hook ladder over the ridge or installs roof brackets, so weight stays off the slate. Work only happens when the roof is dry, since wet slate is slick.
Trace the leak
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.
Remove broken slate
With a slate ripper, the roofer cuts the nails holding the broken slate and draws it out. The slates above stay in place the whole time.
Fit matching slate
A matching slate is fitted and secured with a hook or a covered copper nail so no fastener is exposed. 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 Oradell, NJ
Before repairs, an inspection sorts out whether the slate itself is sound or nearing the end. It covers slate condition, nail failure, valley metal, chimney and wall flashing and any old tar repairs. Hard slate in good condition rings when tapped, while worn soft slate sounds dull and breaks easily.
For a slate roof inspection in Oradell, much of the surface can be checked from a ladder, with binoculars and with drone footage, so the stone is not walked on. Inside, the attic shows where water has gotten through and whether the board sheathing is sound. The result should tell you how many repairs are needed now, what can wait and how much life the slate has left.

Slate Roofing Company Oradell, NJ
Not every roofer works on slate, and the wrong repair can do more harm than the original problem. 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. A roofer whose first suggestion is coating the roof with tar is a red flag.
When looking for a slate roofing company in Oradell, ask about past slate jobs and whether they keep salvaged slate on hand for matching. Salvaged slate that matches the original is the key to repairs that do not stand out. One call to (551) 383-2310 is a good place to start.

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, building ice dams that push water up under the shingles. Coastal storms and heavy spring rain drive water sideways into flashing, valleys and old chimneys. That is why roof repair in Oradell is busiest after a hard winter and before the next one.

Slate Roof Repair FAQ
Can tar be used to repair slate?
Roof cement is a shortcut that tends to cause more trouble on slate. 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.
Why are slates sliding off my roof?
The nails holding each slate are the usual culprit. Many older slate roofs used nails that corrode in time, and once a nail fails, the slate slides out of its row. Individual slates are rehung with hooks, but widespread slipping points to relaying the roof with copper nails.
What is the lifespan of a slate roof?
Hard slate can last well over a century, while soft slate lasts a shorter but still long span. 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.
Can I walk on my slate roof?
Walking on slate is best avoided. 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.
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.
