Mount Lebanon's pre-war housing stock presents one of the most interesting — and demanding — roofing inventories in the Pittsburgh area. Tudor Revival and Colonial Revival homes built in the 1920s and 1930s were commonly roofed in slate, and many still carry that original material in varying states of condition. Where original slate has already been converted to asphalt, the replacement shingles may themselves be 25 to 30 years old and due for replacement. Understanding what is actually on a Mount Lebanon roof — its material, its condition, and its generation — requires a careful inspection that looks beyond the visible surface.
Why Roofing Matters in Mount Lebanon
Pre-war Mount Lebanon homes were built with roof geometries that maximize curb appeal: steep pitches, decorative dormers, eyebrow windows, and hip-to-gable transitions that are beautiful but create complex flashing requirements. Those transitions are where water finds its way in, and where a contractor who does not understand period construction techniques can inadvertently cause more damage than the deteriorated roof they replaced. Ireland Contracting has worked on enough South Hills pre-war homes to approach these projects with appropriate care — and to recognize when a historic slate field has enough life remaining that repair is the better recommendation.
What's Different for Roofing in Mount Lebanon
-
Mount Lebanon pre-war homes may still carry original 1920s or 1930s slate — condition assessment, not age alone, determines whether repair or conversion is correct.
-
Steep-pitch Tudor and Colonial Revival rooflines require experienced valley and dormer flashing work; these transition points are where most roofs eventually fail.
-
Algae-resistant shingles are a baseline recommendation for Mount Lebanon's tree-lined streets, where shaded north slopes see persistent moisture retention.

Roofing in Mount Lebanon — FAQ
How do you handle large mature trees near the roofline in Mount Lebanon?
Overhanging trees are common in Mount Lebanon and we note significant ones in every inspection. Limbs in contact with roofing material accelerate granule loss and can trap moisture that promotes rot at the fascia and decking level. We document the condition in our report and recommend tree trimming as a priority before or shortly after any roofing work. Gutter guards are also a strong recommendation for any tree-heavy property.
How long does a full roof replacement take?
Most single-family homes in the Pittsburgh area can be completed in one to two days, depending on the size of the roof, the number of layers being removed, and weather conditions. We will give you a realistic timeline during the estimate appointment.
What warranty comes with a new roof from Ireland Contracting?
As an Owens Corning Platinum Preferred contractor, we can offer enhanced limited lifetime warranties on qualifying shingle lines that provide stronger coverage than standard installer warranties. Specific terms depend on the product selected — we walk through all options during your consultation.
