Slate Roof Repair New Milford, NJ
Most slate roofs in New Milford 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) 374-2044 to talk with a local roofer about the repair.
A slate roof leak rarely means the slate is worn out. The nails that hang each slate and the metal at valleys and walls are what wear out, long before most of the stone does. 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.
Do not climb onto a slate roof to look. 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.

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. Slate is never worked on while it is wet or icy.
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. Widespread slipping points to nail failure rather than isolated damage.
Cut the old nails
The damaged slate is freed by cutting its hidden nails with a slate ripper. The slates above stay in place the whole time.
Set new 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.
Renew the metal
Valleys and wall flashings that have rusted through are replaced with new metal, with the slates carefully removed and relaid. Copper flashing is common on slate because its service life comes close to that of the stone.
What is included

Slate Roof Inspection New Milford, 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.
In New Milford, 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 New Milford, 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.
A slate roofing company that works in New Milford should be able to describe recent slate repairs and where it sources matching slate. Salvaged slate that matches the original is the key to repairs that do not stand out. Call (551) 374-2044 to talk with a roofer who works on slate.

What the local climate does to a roof
Winters here are long and cold, with snow on the roof for weeks at a time and plenty of nights below freezing. 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. Most homeowners in New Milford, NJ have the roof checked in the fall and again after the snow melts.

Slate Roof Repair questions
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.
Is it safe to walk on a 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.
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.
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. An inspection tells you which way your roof leans.
Can tar be used to repair slate?
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. The lasting fix is replacing the broken slate and renewing the flashing with metal.
