Slate Roof Repair Pequannock, NJ
Most slate roofs in Pequannock 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 (862) 458-0110 to reach a local roofer who works on slate.
A slate roof leak rarely means the slate is worn out. 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. 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. 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.
Depending on what the roofer finds, slate roof repair in Pequannock, NJ can go hand in hand with slate roof replacement and slate roof installation.

How slate roof repair works
Slate repair follows a careful routine.
Stage from ladders
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
Leaks are traced back to their source, which on slate is often a valley, a flashing joint or a cluster of slipped slates. If many slates are slipping, it tells the roofer the nails are failing roof wide.
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
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
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.

Slate Roof Inspection Pequannock, 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.
A slate inspection on a Pequannock 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. The result should tell you how many repairs are needed now, what can wait and how much life the slate has left.

How the weather here affects roofs around Pequannock
Winters here are long and cold, with snow on the roof for weeks at a time and plenty of nights below freezing. 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. Most homeowners in Pequannock, NJ have the roof checked in the fall and again after the snow melts.

Common questions about slate roof repair
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.
Can a slate roof be repaired instead of replaced?
Most slate roofs can be repaired as long as the stone itself is still sound. It is when the slate is delaminating widely, or slipping everywhere, that a full strip and relay becomes the better plan. An inspection tells you which way your roof leans.
Is it safe to walk on a 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.
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. The nails and flashing need attention long before the slate does. With timely repairs, many slate roofs outlive several generations of owners.
What causes slates to slip?
Slipped slates come from failed nails far more often than from broken stone. 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.
