What is considered commercial roofing?
Commercial roofing is roofing work on buildings used for business rather than as a home, such as shops, offices, restaurants, warehouses, industrial buildings and multi-tenant properties. Most of those buildings have flat or low-slope roofs covered by a membrane or metal panels instead of the steep shingle roofs on houses, so the materials, the leak points and the repair methods are different.
What type of roof is best for commercial buildings?
It depends on the building. Low-slope roofs are usually single-ply membranes (TPO or EPDM) or modified bitumen; metal panel roofs suit low-slope and pitched commercial buildings and last a long time when the fasteners and seams are kept up. The right choice depends on the roof deck, the slope, what sits on the roof and how long you plan to own the building. We look at what is on your roof now and explain the options before recommending anything.
How do you repair a commercial flat roof?
First find where the water is actually getting in, which is often not where it shows up inside. On flat roofs the usual culprits are open seams, failed flashing at walls and curbs, cracked sealant around penetrations like vents and HVAC units, and ponding water that works into weak spots. The repair is to dry and clean the area, then patch or re-seal the membrane or panels and rebuild the flashing so the detail sheds water again.
How often does a commercial roof need to be replaced?
Commercial roofs commonly last somewhere between 15 and 30 years depending on the material, and well-kept metal roofs often go longer. Ponding water, foot traffic, storm damage and skipped maintenance shorten that. Regular inspections and small repairs are what push a roof toward the long end of its life instead of an early replacement.
How much does it cost to fix a commercial roof?
It depends on the roof type, the size and access of the area, and what has failed underneath. A seam or flashing repair is a very different job from replacing wet insulation across a section. We inspect the roof first, photograph what we find, and give you a written estimate before any work starts, so you know the scope and the price up front.
Who is responsible for roof repairs in a commercial lease?
Your lease decides that. Many commercial leases make the landlord responsible for the roof structure and replacement and the tenant responsible for reporting leaks or for routine maintenance, but terms vary widely, so check the repair and maintenance sections of your lease. Either way, we can inspect the roof and document the condition with photos that both the owner and the tenant can work from.
