Roofing in Mansilingan

Get at least three quotes from established local firms in Mansilingan, ask each for recent local references and proof of insurance, and check membership of the national roofing trade body where one exists. Prioritise roofers who inspect from the roof (or with a drone) and show photos, over anyone quoting from the ground or the kerb.

Two separate ones: a manufacturer warranty on materials (often 20-50 years, sometimes conditional on certified installation) and the contractor's own workmanship warranty (5-10 years is respectable). Get both in writing and understand what voids them — foot traffic, unventilated attics and pressure washing are common exclusions.

Typical service lives: asphalt shingles 15-30 years, concrete tile 40-60, clay tile and slate 60-100+, metal 40-70, flat membranes (felt, EPDM, TPO) 15-30. Underlayment and flashings usually fail before the covering itself, which is why old roofs leak even with intact tiles.

Yes, over time — moss holds moisture against the surface, lifts tile and shingle edges, and accelerates frost damage. Have it removed by soft washing or manual scraping, never high-pressure washing, which strips granules and forces water under the covering. Zinc or copper strips slow regrowth.

Sometimes — an overlay saves tear-off cost but hides deck problems, adds weight, and often shortens the new roof's life and warranty. Many codes and manufacturers limit roofs to two layers. Tear-off costs more upfront and is usually the better long-term decision; get both options priced.

Re-roofing with pre-painted GI sheets typically runs ₱800-₱2,600 per m² for materials plus labour, with labour alone at ₱150-₱500 per m². A full re-roof of a 100 m² home commonly lands at ₱80,000-₱300,000 depending on gauge, insulation and structure.

In the dry months, roughly December to May. Typhoon season (June-November) both causes the damage and makes repair scheduling unreliable — and post-typhoon demand spikes push prices up and quality down. Pre-season inspection is the cheap option.
