Slate Roof Repair Mountainside, NJ
Most slate roofs in Mountainside 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. Call (908) 728-6030 to reach a local roofer who works on slate.
On a slate roof, the stone is usually the last thing to fail. The nails that hang each slate and the metal at valleys and walls are what wear out, long before most of the stone does. Rusted nails let slates slip loose one by one, which is why slipped slates often show up in gutters.
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.
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 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, a Mountainside roofer may also recommend slate roof replacement or slate roof installation.

The slate roof repair process
Slate repair follows a careful routine.
Set safe access
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.
Pin down the source
The roofer checks whether the problem is a single broken slate, rusted nails across a slope or flashing at a valley, chimney or wall. If many slates are slipping, it tells the roofer the nails are failing roof wide.
Pull damaged slates
The damaged slate is freed by cutting its hidden nails with a slate ripper. Nothing around the repair has to come off.
Fit matching slate
A matching slate is fitted and secured with a hook or a covered copper nail so no fastener is exposed. Matching is easiest with salvaged slate of a similar type and age.
Repair the flashing
Corroded valley metal, step flashing and counter flashing at chimneys and walls are replaced, usually in copper, by lifting and resetting the slates around them. Copper flashing is common on slate because its service life comes close to that of the stone.
What is included

Slate Roof Inspection Mountainside, NJ
Inspecting slate is about telling a stone problem from a fastener or flashing problem. Key checks include the slate type, how many slates are cracked or delaminating, whether nails are rusting and how worn the valleys and flashings are. Tapping a slate is a quick test: sound slate rings, worn slate thuds.
In Mountainside, a slate roof inspection is done mostly from ladders and with a drone so the inspector does not crack the slate checking it. The attic is checked as well for stains, daylight and rotted sheathing boards. 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 Mountainside, NJ
Choosing a slate roofing company matters more than with most roofs, because slate needs its own tools, methods and experience. Ask about their tools and methods: slate rippers, hooks, staging and the flashing metals they use. A roofer whose first suggestion is coating the roof with tar is a red flag.
For Mountainside 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. Call (908) 728-6030 to talk with a roofer who works on slate.

How the weather here affects roofs around Mountainside
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, which is how ice dams form and back 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 Mountainside is busiest after a hard winter and before the next one.

Slate Roof Repair questions
Can a slate roof be repaired instead of replaced?
Slate roofs are built to be repaired one slate at a time. 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.
Is roof cement a good fix for a slate roof?
Tar and roof cement are poor fixes for 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.
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.
What causes slates to slip?
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. 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 is not made to be walked on. 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.
