Luciano did not try to sell me a new roof. Appreciated the honesty — he showed up when he said he would.
We had a leak diagnosed by two other contractors who could not find the source. Blue Knight found it on the first visit and fixed it the same week.
Flat roof replacement on a commercial unit. Clean, fast, no surprises on the invoice. The crew left the site cleaner than they found it.
Called after a storm damaged our roof. Someone was on site within hours, tarped everything, and had us fully repaired before the next rain.
Had a slow basement leak for years. Every other company just caulked it. Blue Knight found the actual source and did a proper waterproofing job. No issues since.
Our neighbours recommended them for a valley repair. Small job, but they treated it like it mattered — showed up on time, matched the shingles perfectly, and charged exactly what they quoted.

Emergency Roof Repair questions for Forest Hill.
Typically within 60 minutes. Forest Hill is central and small, so the drive is seldom what holds us up. The containment itself takes longer here, because protecting slate while stopping the water is slower than simply nailing a tarp down.
It will if it is fastened the usual way, and that is a common and avoidable outcome. Nails driven through slate to hold a tarp break the pieces they pass through and leave holes in the ones around them. We batten and weight instead, which holds in wind without penetrating the covering.
Three things, in order: the water is stopped, the failure is photographed before any sheeting covers it, and the entry point is traced, which on these houses is more often a chimney or parapet than the slate itself. By the time the crew drives off, the water has stopped and you have in writing what gave way.
Yes, including weekends and holidays. On a house of this value the case for stopping water quickly is straightforward: interior finishes, plaster, and original woodwork are considerably more expensive to restore than to protect.
Yes. Photographs are taken before anything is covered, and the report sets out what failed, why it most likely failed, and what the permanent repair requires, down to the slate, tile, or copper specification an adjuster needs to value a heritage roof correctly.
Yes. The lasting repair is priced in daylight once matching slate or tile has been located, which can take a while on a discontinued profile, and we tell you plainly whether the temporary cover will hold safely until then.
Call us once everyone is clear of the rooms below. If the limb is still resting on the house an arborist has to lift it off first, and then we sheet and weight the opening without nailing through the surrounding slate, photograph the broken material and framing, and record it all for your insurer.
Please do not. Wet slate and clay tile are slippery and crack under a boot, so a well-meant look can turn one broken piece into a dozen on a roof that is steep and high. Photograph what you can from inside and from the ground, and leave the roof to us.
Stopping a leak on a heritage roof is its own discipline, and doing it the usual way is costly. The usual emergency tarp is nailed straight through the roofing into the boards below, harmless enough on asphalt that is due to come off anyway. On slate or clay tile those nails crack the pieces they pass through and punch fresh holes in a roof that was sound apart from the one failure, so the containment ends up costing more than the leak.
Our crews hold the sheeting down with weights and battens instead, without a single fastener through the slate or tile. It is slower on the night, and it is exactly why a Forest Hill emergency should go to people who work on these roofs rather than to the first number that picks up.
Containment Without Damage
The central problem in a heritage roof emergency is that the fastest containment method is the one that causes the most damage. A crew working to a stopwatch will nail a tarp down, stop the water, and leave you with a repair bill for the containment itself.
Weighted and battened systems take longer to install and hold perfectly well once they are on. That trade of time for damage is the right one on a slate or tile roof, and it is the practical reason these calls should go to somebody who has done them before.
Protecting Plaster and Woodwork Below the Leak
On a 1920s or 30s house most of the cost of a leak is inside. Original plaster ceilings hold water, sag, and can come down in sections, and oak floors, panelling, and trim stain and cup once soaked, none of which is cheap or quick to restore.
So on arrival we look at what sits under the leak as well as where it is coming from, and move or cover what we can before turning to the roof. Once the water is stopped, the report notes which rooms took water and where, which helps both the insurer and whoever restores the interior afterwards.
Storm Nights Under a Mature Canopy
The trees that give Forest Hill its character also shape its storm calls. High wind brings limbs down onto roofs and into copper valleys, and leaves and twigs packed into valleys and gutters push water sideways under slate that would otherwise shed it.
After a big storm we go first to houses where water is actively coming in, then to those with open damage but dry rooms, and we give every caller an honest time rather than a hopeful one.
We also cover nearby cities.
